Also known as:
Legendary Serial Killer
Jack the Ripper (ジャック・ザ・リッパー, Jakku za Rippā?), Class Name Assassin of "Black" ("黒"のアサシン, "Kuro" no Asashin?), is the Assassin-class Servant of Reika Rikudou of the Black Faction in the Great Holy Grail War of Fate/Apocrypha. Originally summoned by Hyouma Sagara, Reika becomes her Master shortly after.
The Legendary Serial Killer (伝説の連続殺人鬼, Densetsu no Shiriaru Kirā?). Although there are numerous theories about who Jack the Ripper could have been, she is one interpretation of the series of gory murders in 19th Century England. Her true nature is that of a collection of wraiths born from the aborted children of prostitutes in Whitechapel, London. Because she is a collection of wraiths and not a single entity, piercing her heart will not lead to her immediate death, but the spillage of said wraiths.
Once the number of aborted children who were disposed of in rivers reached the ten-thousands, the collection of resentment that the children shared eventually formed the shape of a human. Because she was created from children who had yet to even be born, she lacked common sense and morality, and simply killed prostitutes so she could return to the womb. To put it another way, this is the heretical Jack who was born from the “side of the victims”.
After killing several women, she was given the name "Jack the Ripper," and rejoiced at having been given a name that she had been denied for so long. However, even they themselves do not know for certain whether or not they were “Jack the Ripper”. After all, they are an amalgamation of evil spirits, so their memories are always vague and, even if they remember having killed prostitutes, it’s uncertain who exactly they killed. What they kill as Assassin is not a specific individual, but rather the society that killed them, and the strong emotions they carry cannot be understood by any other hero, making them beyond salvation. Eventually, a magus discovered that the culprit of the bizarre killings was of a magical nature and extinguished her.
She will likely perpetually reign as an eternal mystery and eternal darkness carved into the history of England. While her identity was never discovered, her knives were left behind after her death and later obtained by Hyouma Sagara.
There are a numerous number of incarnations that share the true name of "Jack the Ripper," due to the case never having been resolved. For example, Berserker is a completely different entity from Assassin.
Jack has the appearance of a white-haired (lavender in the anime, and promotional and supplementary materials) girl with green-yellow eyes, with stitched-up scars on her face. Her upper body is that of a adolescent, while her lower body is more mature like that of an adult, creating an odd juxtaposition to her appearance. She dons a black vest, black panties and black stockings with pink shoes. Both her arms are bandaged but only her left hand wears a glove. She has a purple oval-shaped 'O' on each of her shoulders. At the small of her back she carries a number of sheathes that holds her knives. In her first stage in Fate/Grand Order and in the anime, she wears a tattered coat as a cloak over her outfit.
She is a young girl who embodies contradiction itself, combining the dual natures of "day" and "night." She displays a childish manner of speech, but she is truly quick of thought. Rationality dominates her behavior, but there are many inherent weaknesses to her psyche. Her personality is both pure and cruel, and she is inclined to repay cruelty with cruelty and benevolence with benevolence. To her killing is no different than it would be to pick a flower or step on an ant. Her psyche is inherently broken, and mistreatment toward her may result in irreversible deterioration. She uses first person plural pronouns, such as "us" and "we", to address herself, and often lamented the fact that all of the voices she heard on the streets would never mourn "them."
Due to her time on the streets, her ultimate wish from the Holy Grail is to return to the safe and comfortable warmth inside her mother. This desperate wish was the driving motivation behind the murders. While dissecting the women she labeled as her "mother", she would constantly apologize that she wants to "go back" while crying and rubbing a part dissected from the woman against her face. Rather than continue on the cold streets, she wished to return where it was warm.
As a child that was never loved, she strongly seeking out for love. Regardless of whatever the Master is male or female, she will probably demand his/her love as a "mother". While there is no problem in responding to that love, she might intend to sneak into your abdomen. Considering that, the compatibility between Jack and their former master Hyouma Sagara was pretty much the absolute worst possible—or rather, perhaps it is better to say that all magi have the worst compatibility with Jack. Reika Rikudou is the only Master that is compatible with the existence known as Jack. While she fawns over her wounded Mother, Reika Rikudou, she easily turns cold and maims her proper Master, Sagara Hyouma, with ease before returning to her concerned filled expressions towards Reika. After casually devouring him, she turns childishly bashful and asks Reika to pat her head. Despite becoming easily flustered by Reika's question a moment earlier, she can just as easily casually rip out and eat the hearts of loan sharks without any expression. She is extremely affectionate and childlike towards her Mother, but cruel and ruthless towards others.
Reika feels that the Servant's disposition sometimes matching that of the Master is true in their case. She, who does not truly feel alive, and Jack, for whom the word "alive" may not even be applicable, met due to fate. She is surprised by the notion of having a home to return to after having lived out on the streets her entire life. Remembering her desperate struggle for survival, she cannot help but feel that "going home" is an occasion that has nothing to do with her. While Servants do not require food to survive, Reika tells her that she is going to cook dinner for her. While she is initially unresponsive to the idea, once Reika tells her it's a reward for her work, she smiles happily and dances around in joy.
Fate/Apocrypha Act1: Unbirth
Hyouma Sagara, a magus, wishes to summon Jack the Ripper as a Servant, but he fails to do so even with her six knives as the catalyst. He concludes that he needs to create the conditions where the blades were practically used in order to establish a better connection. He quickly decides to use Reika Rikudou, a prostitute he is living with, as a sacrifice. In his attempt to summon Jack by killing her, Reika's wish to live is what brings Jack into the world. While Sagara is the proper Master with Command Spells, Jack quickly shows that she has concluded that Reika is her Master instead. Before he can tell her to commit suicide after realizing something is wrong with the situation, she incapacitates him by cutting off his jaw and the hand with the Command Spells. She uses her skills to stitch up both their wounds while Reika is unconscious.
She explains the nature of the Holy Grail War to Reika upon arriving at her apartment. She is able to transfer the Command Spells from Sagara's hand to Reika, but she is not a magus or a proper Master. This requires that she devour souls in place of being unable to restore magical energy from her Master. She uses Sagara at Reika's suggestion, and they decide to participate in the War together. Jack's memories appear in Reika's dream during that night, and she sees Jack cutting open a woman to return to where it was warm. They target a loan shark company full of "bad people" the next day in order to gather energy for Jack. She uses the Mist to kill them all, and then they return home for a meal afterward.
Fate Apocrypha: Zugzwang
Hyouma Sagara was betrayed by Assassin.
The Beginning Stages of the Great Holy Grail War
While Assassin was originally meant to be summoned in London, it became enemy territory after Yggdmillennia seceded from the Mage's Association. Assassin was instead chosen to be summoned in Japan near a leyline that suited her. After the murder spree in Japan, she and Reika arrive in Bucharest, Romania several days later. Searching out people to kill for her to eat, they hear of the "children of Ceaușescu", and Reika acts as bait in order to capture one for information. After she is attacked by two men, one is slain by Assassin and the other is kept alive to gather information. Though the man tries to resist, it is futile with only the strength of a human, and Assassin incapacitates him to stop further resistance. After Reika obtains the necessary information, Assassin is allowed to eat him, and they go on to slaughter the man's comrades, leaving fifteen corpses in total before moving on to Trifas. Though the circumstances of the murders are strange, all of their hearts being ripped from their bodies, the authorities believe it to be from an internal struggle among the criminal groups, but one paper jokingly publishes the headline "The Return of Jack the Ripper?"
First Battle with Assassin of Black
Kairi Sisigou and Saber of Red are informed of these murders by the Mage's Association, leading them to investigate the pair. The Black Faction also takes note of the mysterious murders and sends Fiore Forvedge Yggdmillennia and her Servant, Archer of Black, to find if the culprit is possibly the missing Assassin of Black. During the night, Assassin of Black confronts Saber of Red, whom she fights. Their battle is interrupted by an attack of Archer of Black that wounds Jack, causing her to retreat, while the members of the two Factions are left to battle each other. Jack is later comforted by her "mother", Reika.
Siege on Castle Yggdmillennia
Jack briefly appears during the first large battle between the Red Faction and Black Faction. She doesn't fight for either side, but instead kills the homunculi and golems to feast on their magical energy.
Hunt for Assassin of Black
Later on, the Black Faction, with the support of Ruler, decide to deal with the problem of Assassin of Black, who has been killing more people around the town. As they investigate the murders, Assassin sneaks into the castle of Yggdmillennia, where she attempts to kill Fiore. Sieg also tries fighting Assassin, although he is outmatched. However, before Assassin can kill either of them, the group that had been searching for her to return, causing Assassin to retreat.
After the incident, the Black Faction makes a plan to draw out Assassin. Sieg and Ruler walk around this time, waiting for Assassin to attack them, while Archer of Black and Rider of Black are ready to attack when she appears. The plan initially goes smoothly until Assassin manages to escape, although she badly injured. She finds Reika, who comforts her once again. However, Archer of Red then appears attacking both Assassin and Reika. Reika uses herself to shield Assassin, dying in the process.
Shocked by her "mother" dying, Jack materializes an image of the dark streets of London where many orphan children were abandoned. Archer of Red's mental state is also greatly affected by Assassin, causing her to become frantic. Ruler confronts the children who make Assassin, wanting to free their tormented souls, while Archer of Red tries to stop her, due to wanting to protect all children. Ruler manages to convince the children to give up, allowing her to release the binding as an amalgamation of evil spirits, so that they won't ever be summoned. Even if the conditions as exactly the same, a different "Jack the Ripper" will be summoned.
Fourth Singularity: London
Jack is a Servant that materialized from the Demonic Fog. She spends her killing humans out on the street, particularly women. She later ambushes Ritsuka and Mash as they wander through the streets of London. She wonders what they are, given that they’re unhindered by neither the Demonic Fog nor her own. She is delighted Mash knows about her, then attacks her and Ritsuka. She is forced to retreat; Her Skill removes the encounter from Ritsuka and Mash’s memories and Romani Archaman‘s observational records.
She is later commanded into attacking Scotland Yard by Paracelsus von Hohenheim so he could retrieve a certain item. By Ritsuka, Mash, and Mordred arrive at the police station, she has already slaughtered everyone inside. Paracelsus then orders her to kill the group, telling her that one of them might be her mother. She is slain and disappears asking why.
Christmas Event: Miss Almost Weekly Santa Alter
Feeling alone and confused on Christmas, Jack and Nursery Rhyme encounter Julius Caesar. They mistake him for Santa Claus, but he tells them to wait patiently for the real Santa since he isn’t it. Before leaving Caesar tells them to be good girls and wait patiently until then and that he’ll try to do something for them next year if they can’t do that.
Later, Jack and Nursery Rhyme summon Ritsuka and Santa Alter into their inner world. Santa Alter confirms that she is indeed Santa and asks what they are. They answer they don’t know, nor do they have names either. Santa Alter believes they’re the unfulfilled spirits of young girls who died innocent yet ignorant of love. Jack tells her it isn’t as complicated as she makes it.
Because they didn’t a letter to Santa, Santa Alter has Jack and Nursery Rhyme fight her to prove they’re worthy of getting presents. They are defeated, however, and despair that there won’t be any Christmas for either of them. To their confusion though, Santa Alter over-dramatically pretends to be defeated by them, and gives a whole plethora of Christmas presents. They thank her for the presents, but Jack asks if there aren’t many other children waiting for their presents as well. Santa Alter answers not to worry and that she only has one more stop, and says that the presents are the spoils of their victory not their actual individual presents. She then gives them their presents. As Santa Alter goes to leave, Jack stops her to thank her for granting her and Nursery Rhyme’s wish. Jack and Nursery Rhyme then tell Santa Alter about their encounter with the other Santa.
Valentine Event: Chocolate Lady's Commotion
Jack is the second trial that Mash must face in a series of combat trials Stheno and Euryale set up to increase the hype of Valentine's Day. At first, though Jack intensely begs Mash to give her chocolate. Mash refuses, telling her to ask Romani. Jack responds by attacking Mash. She loses, saying she only wanted candy. She lets Mash pass, though, when Mash promises to give something sweet later. But she is disappointed upon hearing it'll be a sesame bun.
Christmas Event: The Second Generation is Alter
Jack and Nursery Rhyme are in Asterios' labyrinth preparing for a Christmas eve feast with him and EMIYA. They're disappointed when Asterios says he doesn't want anything. Nursery Rhyme asks him what he wants, to which Asterios says it's a secret. Both Nursery Rhyme and Jack pray that his wish comes true. Asterios then senses that someone is nearby. Nursery Rhyme and Jack assume it's Santa and run off to meet them.
The two eventually find Jeane Alter Santa Lily, who got lost in the labyrinth with Ritsuka. Assuring them that she's fine, Alter Lily asks them if they're the ones who asked Santa for presents. They confirm this, but they're confused since she isn't Santa Alter. They wanted to thank Santa Alter for giving them lots of presents on their first Christmas. They then force Alter Lily to fight them since Santa Alter taught them that they need to fight to earn their presents.
She defeats them, so neither Jack nor Nursery Rhyme gets any presents according to Santa Alter's rule. Santa Island Mask arrives and convinces Alter Lily to pretend to have lost to Jack and Nursery Rhyme. She proceeds to do so, explaining their late victory is because they used Damage over time. Pretending to be too weak to move, she decides to give them their presents. Jack asks if Santa Mask is her mommy. Santa Mask answers he isn't but tells Jack that Christmas is a day when everyone is her mommy. While Jack is elated by this, Ritsuka can only imagine the potential horror. After Santa Mask leaves, Jack and Nursery Rhyme invite Alter Lily to their tea party. She thanks them for the invitation, and tells them she'll give them their presents there.
She gives Jack and Nursery a hermitage as their present since she believes they need a quiet place to study instead of playing. She tries to explain why it would be good for them but then decides it wouldn't be and runs away. Ritsuka, Jack, and Nursery Rhyme eventually find her alone in a snowfield. Alter Lily is dejected when Jack and Nursery Rhyme when they return their present to her. They tell her, though, that they want to see the sea, having heard of it from Asterios. Santa Mask appears and encourages Alter Lily to grant their request since she took back their gift. Alter Lily has Jack and Nursery Rhyme board Llamrei II so she can take them to the sea.
As the group flies to their destination, they are suddenly pulled down by a Servant down below. Upon crash landing, they are confronted by Leonidas. Alter Lily defeats him and proceeds onward with the others following another encounter with Santa Mask, leaving the broken sleigh behind. They later set camp in a forest and eat the feast EMIYA had prepared earlier.
The next morning, the group prepares to continue west to the sea when Hassan of the Cursed Arm appears, declaring he cannot let them go to the sea. He introduces the true Santa, Santam, who Alter Lily, Jack, and Nursery Rhyme immediately realize he's just EMIYA wearing a mask. This shocks EMIYA since they couldn't figure out Santa Mask's identity. Ignoring that, EMIYA fills Alter Lily with doubt regarding her role as Santa. Yet despite her doubts, Alter Lily decides to fight, declaring herself to be Santa since she was entrusted with Santa Alter's sack. She defeats EMIYA, who departs, telling her not to forget her duties.
Getting closer to the sea, Ritsuka carries the girls as they run from a horde of living dolls. Ritsuka trips over a pebble, however, so the group is forced to fight the dolls. After the dolls are destroyed, Santa Mask appears and claims he led Alter Lily into his trap. He wants Santa's sack for himself and tells Alter Lily that self-interest and the desire to grant wishes are unnecessary for Santa. Jack asks Alter Lily if she wants to come with her and Nursery Rhyme to the sea, as they both want her to. Calling their wish nonsense, Santa Mask demands the sack again, but Alter Lily refuses to give it to him. She declares she will not hand the sack to someone who insults children and decides she must defeat Santa Mask. After defeating him, Alter Lily tells Santa Mask to step aside, which he does since he has seen her resolve as Santa. He continues to talk until Jack points out that Alter Lily is already gone to his disappointment. He then entrusts Alter Lily to her.
As they continue towards the sea, Nursery Rhyme and Jack notice that Alter Lily is trembling. They hold her hands, and the three continue ahead of Ritsuka. By dusk, the girls reach the shoreline. Alter Lily starts to cry aloud, having now realized she wanted to see the sea. She apologizes to Jack and Nursery Rhyme for bringing them to the sea to grant her wish, not theirs. They tell her that it's fine, believing she did her best as any Santa could. She then listens to the waves with them.
Final Singularity: Solomon
Event: All the Statesmen!
She and Nursery Rhyme were summoned by the Nameless Master. They were then left at a decrepit house in Wisconsin's Central Plain. There they wait for their summoner to return from Chicago.
When Ritsuka's party comes to the house, Jack and Nursery Rhyme share their last hamburger steak with Paul Bunyan. A stampede of rampaging buffalo then hits the house, so the group goes out to take care of them. While eating the buffalo they killed and cooked, the group encounter Altera ( calling herself Buffalo Bill). She decides to punish them for killing the endangered buffalo, ignoring Geronimo's statement that the herd was berserk and none of their parts were wasted. After being defeated, she retreats, warning the group not to go any further. Now joined by Jack and Nursery Rhyme, the group continue onwards to Chicago.
Eventually reaching Chicago, the group split off in search of clues. During this time, Bunyan has pizza with Jack and Nursery Rhyme. But rendezvousing later that night, only Geronimo has useful information. He informs them of a shop called the "Club High Society", a place he assumes is backed by the Mage's Association. Thomas Edison bribes a bouncer to let them in; Jack and Nursery Rhyme aren't allowed since they're children.
Afterward, the group goes to the Columbian Expedition, having learned Bunyan's summoner is there. Altera (now calling herself Davy Crockett) arrives to stop the group from going any further, along with Nikola Tesla. They end up fighting when Edison becomes enraged by Altera calling DC electricity bad civilization. After Tesla disappears, Altera leaves, warning Ritsuka and Bunya they'll encounter their worst nightmare if they go any further.
At the center of the fair, the group finds a poorly constructed Japanese Pavillion. There they encounter the Nameless Master, the one who summoned every Servant the group encountered, except for Bunyan. Bunyan is a Phantom born from a joke between North American settlers with no basis in myth or belief in her existence. The Nameless Master allowed her to possess udon dough and hoped to shape her into a powerful welfare Servant for the game's second anniversary. But considering her a useless low-rank Servant, she trapped Bunyan in the Singularity. She then decides to eradicate the group for bringing Bunyan, whom she wanted her to disappear in the forest. Despite them being all high-ranking Servants, the Nameless Master's Servants were underleveled and easily defeated. She asks for Jack and Nursery Rhyme's help as she starts to disappear. But they refuse to and leave their summoner to disappear.
Later, as Bunyan expanded Chicago to cover much of the globe, Edison's lab was blown up by Goddess Columbia. Jack and Nursery Rhyme are already there when the others come to investigate. She admits she killed Edison for getting too close to the truth, that being that the Singularity is a Reality Marble formed from Bunyan's consciousness made stronger thanks to the Grail's power within her. She reveals the Nameless Master meant to seal Bunyan away in her own inner world, only to become trapped as well. The Nameless Master took away Bunyan's axe so Bunyan couldn't destroy the world by redeveloping it to its limit. However, that cycle resumed when she got her axe. Her Reality Marble began to encroach onto Ritsuka's world when she saw their Chaldea thanks to Edison's Spiritual World Communicator, which caused the Servants to act bizarrely. Columbia thus determines Ritsuka's party must stay in Bunyan's world to maintain the balance. The group pushes her back in the ensuing fight. Columbia declares she must seal Bunyan away, considering her too dangerous. Overhearing this, Bunyan decides to end it all and transports everyone to her unconsciousness.
Ritsuka's party finds itself in a stormy environment surrounded by multiplying wendigos. Mash realizes they are the citizens of Chicago transformed by Bunyan's fear and sadness. Geronimo decides to fully unleash his Noble Phantasm to open a path out for the others to escape through, thereby sacrificing himself. Edison stops him, however, having faked his death. He then uses his Noble Phantasm to reveal the truth that Bunyan pursued: the scene of a peaceful city. To maintain this scenery, Edison will continue to use his Noble Phantasm. He then leaves the matter of Bunyan to Ritsuka, suspecting she is at the edge of the city.
The group runs into Columbia. She demands their cooperation in destroying Bunyan's Grail before she becomes registered in the Throne as a Heroic Spirit. While she sympathizes with their desire to save Bunyan, being a fabricated goddess herself, she still decides to kill Bunyan to save the world. Ritsuka's party defeats her, and she tells them Bunyan is deep in the forest. After she disappears, the group head for the forest.
They find Bunyan and convince her that she isn't worthless. They try to remove the Grail from her, but Bunyan loses sense of them as she continues to grow. This threatens the group's existence since anything that Bunyan doesn't sense in her world doesn't exist. Fortunately, Altera arrives and destroys the Grail in Buyan with Teardrop Photon Ray.
However, in exchange for the Grail's destruction, Bunyan is registered in the Throne of Heroes. She returns to Chaldea with the others, and together they eat hamburger steak.
Event: Inheritance of Glory
Following the conclusion of the Great Holy Grail War, Darnic Prestone Yggdmillennia, still fused with Vlad III, remained in the Greater Grail. Stilling wishing to acquire the Grail, he manifested mindless replicas of the war’s participating Servants (except the Rulers) to fight endlessly in a recreation of the war inside a recreation of Trifas.
Due to Sieg's influence, Jack, Avicebron, and Shakespeare manifest with a sense of self the following morning. Jack wakes Ritsuka up and immediately identifies them as her "mommy". Sieg barges in to inform that Jack, Avicebron, and Shakespeare have re-materialized, but he sees they've already met Jack. After confirming to Jack that he's a friend, he brings Ritsuka to the garden to meet Avicebron and Shakespeare. There Jack asks Sieg if he's avoiding her. At first, Sieg denies that he is, but quickly admits to it. He confesses he saw her past, calling it horrible. Jack asks him why the pasts and memories of others matter to him. Sieg answers it's because he cares and confesses he wanted to save her, but he couldn't. He then changes the conversation to be about food.
Later that night, the group defends the fortress from the replica Servants. Jack initially wants to stay with Ritsuka, but they and Chiron convince her not to. After the Servants disappear with the rising sun, Achilles discusses with Sieg on how it's possible for all the replica Servants, even those with divinity, to be able to harm him. Chiron then tells everyone to return to the fortress quickly upon suspecting the absent replica Shakespeare infiltrated the fortress to kill Shakespeare.
Fortunately, the group finds Shakespeare safe and sound. Sieg and Chiron agree that the enemy may become more aggressive now that they’re gaining the advantage. They're later joined by the re-materialized Atalanta, Spartacus, and Frankenstein. The replica Servants attack the fortress again later that night. Atalanta starts off by deploying Phoebus Catastrophe, but Astolfo uses Hippogriff to avoid it. While she, Chiron, Achilles go engage the enemy directly, Sieg asks Jack to describe the enemy. Jack gives descriptions for Mordred, Siegfried, and Astolfo. She also reports she saw Shadow Servants and suspects they're leftovers from last time. Sieg decides they will defeat the enemy while protecting the Casters. The group then proceed to defeat Mordred, Siegfried, and Astolfo. After the enemy disappears when the sun rises, Sieg expresses concern that the Grail’s possession ration isn’t changing to their favor. If it remains so, someone other than him will gain control of the Grail. Jack asks why he's risking his life over this. Sieg confesses he stopped a Servant from using the Grail to grant their wish, so he feels a responsibility to ensure the Grail is never misused again.
The next day, the group is joined by the re-materialized Astolfo, Siegfried, and Mordred. During a meeting in the garden, it is determined that the Hanging Gardens of Babylon is the enemy base. While agreeing with a direct assault, Chiron warns their chances of success will be low since twelve Servants will be guarding the Gardens. Avicebron advises against attacking the Gardens during the day like Atalanta proposed, as a flying golem he sent there on Chiron’s order was forcibly transported outside when night arrived. Chiron asks Sieg if he can move his main body, Fafnir, now. Sieg answers he can fly at a minimum but warns he’ll fall if hit by a Noble Phantasm, especially Balmung. Jack decides she will use her mist, divulging that she can select who it envelops. She also chooses to ride on Fafnir alongside Ritsuka. The next day, before the assault, everyone eats strawberry sandwiches in the garden. Jack unnerves Atalanta by saying blood and strawberries both taste sweet.
Later that night, the group flies towards the Gardens. Karna keeps blowing away Jack's mist, much to her frustration. Fortunately, Karna is struck into the Gardens by Mordred and Frankenstein, who launched themselves from the ground with an amplified Mana Burst. The group then enters the Gardens and defeats Karna and Semiramis, who rematerialize with a sense of will come morning. They are then guided by Semiramis to where the enemy resides, the Grail’s chamber.
At the Grail’s chamber, the group meets Darnic Prestone Yggdmillennia, the mastermind behind the recreated Great Grail War. Sieg explains who and what Darnic is. He tries to convince him to surrender, saying a broken Grail cannot reach the Root nor activate the Third Magic. Darnic refuses and reminds the group that he already controls 87% of the Grail. He declares that as long as he possesses the Grail, none of them will ever disappear, but they will once he’s gone. He then proposes using the Grail to incarnate them if they agree to join him. But they all refuse his proposal on their own principles as heroes. Expecting that to be their answer, Darnic connects to a replica of the Grail that emerges from within the Grail to Sieg’s shock. He then fights the group by having the replica Grail continually spawn replica Servants. The group struggle at first since the replica Grail is using their class affinities against them, so they decide to do the same.
After the replica Grail is destroyed, Darnic refuses to give up when he’s struck by Kazikli Bey from the supposedly sealed Vlad. Unlike the others though, he retained his memories of the Great Grail War due to Darnic fusing with him during it. He eventually convinces Darnic to accept that his broken dream can never be recovered. After Darnic and Vlad disappeared, Semiramis teleports the group back to the ground. On the ground, Jack says she won't miss Ritsuka, as she knows they'll keep their connection alive with the her in Chaldea. She then disappears, wondering if she'll see Sieg again.
Her weapons include four strangely-shaped knives, two butcher's knives, and a black, bloodstained scalpel. However, in addition she possesses an unknown number of other black scalpels that she uses as throwing projectiles. She is shown capable of holding up to four per hand for a total of eight and throw them simultaneously. Compared to other Servants who have garnered legends over centuries and millennia, she is a young Heroic Spirit of only one hundred twenty years. Even with the fame she garnered that gives her the necessary "monstrosity" befitting of a Heroic Spirit, she cannot hope to match those worshiped as gods and heroes with such little history of her own. She can be called a completely unknown Servant, and she has never participated in the Holy Grail War. This suits Hyouma's plan, as he wishes to avoid the weakness granted to those of the Assassin class. It is normally fixed that only one of the Hassan-i Sabbah can be selected as Assassin, so it is possible to develop countermeasures against them simply by having their identities as Assassin exposed. With a different Heroic Spirit, it is possible for him to best make use of the class. She has the qualifications to be summoned as either Assassin or Berserker.
She can utilize the evil spirits comprising her to possess children to act both as her soldiers and hostages. If her heart is pieced, the spirits are released from the focal point that is "Jack the Ripper", like a stream of black mud-like mass from her mouth. These spirits attack the nearest living being to trap their victim in a illusion of Whitechapel formed from their memories. It is an inner world that embodies Assassin's origin, and shows the ugliness of humans. The illusion is destroyed if the spirits are exorcised.
Due to being a murderer, their efficiency as a “soul eater” is extremely high, and even with Reika who was an ordinary person and virtually unable to provide any Magical Energy as a Master, they were able to continue maintaining their first-rate battle power by continuing to kill others for Magical Energy. Reika cannot act as Jack's main magical energy supply due to not being a magus, and while the cost of an Assassin-class Servant is less draining than a Saber or Berserker, she still has to acquire it from other sources. She eats humans souls to replenish herself, feeling considerable hunger when low on energy. Due to her nature as chaotic evil, an existence that preaches chaos in the face of order while carrying out evil deeds, souls of the same nature are more easily digested. Eating evil people is the best for her because it is more polluted and delicious. Hyouma works well for her, especially his quality as a magus. She sucks out all of his blood, leaving him much like a pile of dead leaves with the exception of the hand that had his Commmand Spells. She mainly eats the hearts of her other targets instead of devouring them fully.
- Presence Concealment (A+ Rank): A skill suitable for espionage activities, hiding one's presence. If one completely hides their presence, discovery becomes nearly impossible, even for servants. When launching an attack, the rank of the presence concealment greatly decreases, but this weakness is compensated for by "Murder on a Misty Night", allowing for a perfect surprise attack.
- Mad Enhancement (C Rank): If summoned as a Berserker, she gains this skill. Increases all parameters in rank with the exception of Luck and Mana, but removes the ability to speak or have complex thoughts. As a Berserker, she is only active at night, with The Mist always active, and will attack anything that possesses mana.
- Murder on a Misty Night (A Rank): Since her characteristics are that of a murderer rather than an assassin's, she, the assailant, always gets the first move against the enemy, the victim. However, this only applies at night. During the day, a luck roll is required. Jack the Ripper's victims are believed to have all been attacked while off-guard.
- Mental Pollution (C Rank): Mental Interference magecraft has a medium chance of being blocked. If her Master has an evil alignment, or is cruel to her, this mental pollution gradually rises. Her chances of blocking magecraft will increase, but her already broken spirit will begin to irreversibly corrupt.
- Information Erasure (B Rank): The very second battle is finished, eye witnesses and opponents' memories about information concerning abilities, True Name, appearance etc disappear. Even if the battle took place in broad daylight, or was recorded on a device such as a camera, this skill will still take effect. To counter this, one must deduce her identity from evidence left at the scene.
- Surgical Procedure (E Rank): Using her blood-stained scalpels, she can provide medical treatment to the Master as well as herself. It looks risky, but she manages somehow. Can heal her Master or herself using a blood-stained scalpel. The techniques are from 120 years in the past, but are improved a little with mana. Jack the Ripper killed victims in ways that would require anatomical knowledge, such as removal of specific organs. It allows her to heal Reika's stab wounds. Reika finds that her wounds have been stitched up, but it is done in a crude method looks like the black thread is creeping about haphazardly like an earthworm. While it seems like her wounds may not even be closed properly, the bleeding and pain have completely subsided. The same chaotically done surgical procedure is also able to keep Sagara alive after Jack cuts off both his jaw and one of his hands.
Creation and Conception
She was designed by Yuuichirou Higashide and illustrated by Taketo Sanada for the original canceled online game project. Jack's height and weight were originally 150 cm/45 kg in Fate/Apocrypha and Fate/Grand Order, but it was later updated in Fate/Grand Order as being 134 cm/33 kg.
In the design process, if summoned by a female Master, she will begin to refer to them as "Mother." When she addresses them, they hear a strange sound, as though she is pronouncing both "Master" and "Mother" at the same time.
Her backstory had been heavily revised, changing from the original backstory in Unbirth after the release of the Fate/Apocrypha material book. Originally, she grew up without ever having a home, and spent her time living in the streets. She was extremely thin, and lived outside even during cold weather. She only has memories of the alleyways shrouded in mist and stench. The areas where she slept were not places of rest, but rather nests covered in waste and feces where filthy rats ran about. She was in constant danger of being attacked at night while she slept, and upon waking up on the morning, someone may have easily died during the night. She constantly dealt with pitch black smog so bad that she often couldn't breath properly or even open her eyes.
She eventually reached the point where her mind could no longer deal with the conditions. Upon randomly finding prostitutes, she would impose her image of a mother onto them. While better off than her, they were still crushed by their daily lives, having been worn down to existences that simply struggled to live day by day. While suffering from poverty and wondering whether they would die from starvation or disease, they simply told her to leave. Aware that she would be rejected, she hung her head, held back the tears, and wandered the streets once more without change. If she came into contact with her "Mother" again, she would slowly approach within the mist, and after saying "I'm sorry", she would slit their throats. As they were in anguish, she began to dissect them while in tears. After obtaining a part of the woman, she would press it against her face and cry while remembering the warmth of her mother's womb.
While she is thought to be a legendary serial killer who knew of dissection and slipped into the darkness of night to quietly perform his work, the true form of Jack the Ripper is just a pitiful girl. It is believed that all of her victims were assailed when unguarded, and they were all found with organs removed in a somewhat skilled fashion. Her lamentations never reached anyone, and it is unknown how she eventually faded away after the murders. No one knows if she was killed, committed suicide, or simply passed away naturally.

In the case that not all conditions are met only simple damage is dealt, however, as each condition is met the power rises. This Noble Phantasm is not a knife attack but a kind of curse which makes long range use available.
To defend against this Noble Phantasm, rather than physical defense resistance against curses is necessary.

Jack the Ripper, Legendary Serial Killer
The perpetrator of a series of bizarre murders in 19th Century England. A young girl filled with contradictions, possessing properties of both day and night. Her personality is pure, but cruel at the same time. Though her manner of speech is innocent, she is quick of thought. She is rational, but is emotionally weak. She responds cruelly to others' ill will, but is soft against good will. And although she wears revealing clothing, she is shy, and doesn't go out during the day. She yearns strongly for a mother, and if her Master is female, she will insist on calling them "Mother".

- Misty Night Murderer - Rank A:
As a murderer rather than an assassin, she can strike before her victim. However, she can only unconditionally take the first strike at night. During the day, a luck roll is required. Jack the Ripper's victims are believed to have all been attacked while off-guard.
- Information Erasure - Rank B:
At the instant a battle ends, her abilities, true name, appearance, and other information disappear from witnesses' and enemies' memories/records, even if the battle took place in broad daylight, or was recorded on a device such as a camera. To counter this, one must deduce her identity from evidence left at the scene.
- Mental Pollution - Rank C:
Has a moderate chance of blocking mental interference-type magecraft. If her Master has an evil alignment, or is cruel to her, this mental pollution gradually rises. Her chances of blocking magecraft will increase, but her already broken spirit will begin to irreversibly corrupt.
- Surgical Operation - Rank E:
Can heal her Master or herself using a blood-stained scalpel. It looks risky, but she manages somehow. The techniques are from 120 years in the past, but are improved a little with mana. Jack the Ripper killed victims in ways that would require anatomical knowledge, such as removal of specific organs.
- Presence Concealment - Rank A+:
A skill that suppresses presence as a Servant, suitable for covert action. If presence were fully suppressed, she would be nearly impossible to detect. However, when prepared to attack, Presence Concealment's rank falls substantially. This weakness is compensated for with "Misty Night Murderer", allowing for a perfect surprise attack.
- Mad Enhancement - Rank C:
If summoned as a Berserker, she gains this skill. Increases all parameters in rank with the exception of Luck and Mana, but removes the ability to speak or have complex thoughts. As a Berserker, she is only active at night, with "Darkened Misty Metropolis" always active, and will attack anything that possesses mana.
- Maria the Ripper: The Holy Mother of Dismemberment
Normally four D-rank knives, but under certain conditions, they are boosted by the grudge of "the 80 thousand children in London's slums, abandoned by prostitute mothers for the sake of their livelihoods, unable to even become prostitutes", with brutal results. There are three conditions. "It is night-time", "the target is a woman (or female)", and "it is misty". When all the conditions are fulfilled and the Noble Phantasm is activated, the target's innards are forced out of their body, and they become a dismembered corpse. When the conditions are not met, it is limited to simple damage, but increases in power with each condition that is fulfilled. As the Noble Phantasm is not an attack from a knife but rather a variety of curse, it can be used at long range. To defend against this Noble Phantasm, resistance against curses is required, rather than physical defence.
- The Mist: Darkened Misty Metropolis
A Noble Phantasm that creates a mist-filled barrier. The mist itself, created with mana, is the Noble Phantasm. Although it is a means of keeping people out, a non-magus trapped inside the barrier will die after a few turns. A magus will not die immediately, but will take continuous damage. A Heroic Spirit will not take damage, but their Speed will decrease by one rank. The user of the Noble Phantasm is able to choose who is or is not affected by the fog. As those trapped in the fog lose their sense of direction, an "Instinct" skill ranked B or higher or some kind of magecraft is necessary to escape. The large quantity of soot emitted from the Industrial Revolution onward became a smog of sulphuric acid that caused disaster to London in the 1950s. "Darkened Misty Metropolis" is a Noble Phantasm that reproduces that "mist of death".

Assassin of “Black” [Servant]
One of the Servants of the Black camp… or so they should have been, but she deserted and took action independently. Their true name is Jack the Ripper. The serial killer from London who is the most famous of their kind in the entire world.
Usually, serial killers fall into two general categories. The orderly type and the chaotic type; those who can commit murder while maintaining a certain amount of reason and order, and those who commit murder based on reasons that are completely illogical and no one besides themselves can understand. The first type is overwhelmingly harder to catch, since the second type does not even destroy the evidence of their crimes. And Jack the Ripper was the chaotic type.
Even though much evidence was discovered, Jack the Ripper was never caught. It has been cited to have been due to the limits of scientific investigation at the time and due to the initial investigation getting a late start because the victims were only prostitutes.
On the other hand, despite being a chaotic type serial killer, Jack the Ripper also displayed actions such as sending a letter to a newspaper and inciting a panic. Though there is a strong possibility that the letter was a fake, there was no evidence that could completely prove it was a forgery.
The reason that Jack the Ripper is, in a certain sense, so universally extolled throughout the world is due to the overwhelming number of mysteries surrounding this serial killer. Therefore, when Jack the Ripper is summoned as a Servant, he or she can undergo various changes depending on the class or location he or she is summoned in. These changes continue to occur, except in the case where the “true Jack the Ripper” was fixed and settled by the Holy Grail.
…The Jack the Ripper that was summoned this time is an amalgamation of the children who were aborted by the many prostitutes who lived in White Chapel, London. Having not even being allowed to be born, these boys and girls sought to return to their mothers’ wombs and repeatedly committed murder. To put it another way, this is the heretical Jack who was born from the “side of the victims”.
However, even they themselves do not know for certain whether or not they were “Jack the Ripper”. After all, they are an amalgamation of evil spirits, so their memories are always vague and, even if they remember having killed prostitutes, it’s uncertain who exactly they killed. What they kill as Assassin is not a specific individual, but rather the society that killed them, and the strong emotions they carry cannot be understood by any other hero, making them beyond salvation.
Perhaps due to their great fame, they stand out as an excellent Servant. Due to being a murderer, their efficiency as a “soul eater” is extremely high, and even with Rikudou Reika who was an ordinary person and virtually unable to provide any prana as a Master, they were able to continue maintaining their first-rate battle power by continuing to kill others for prana.
On the other hand, their difficulty in being handled by their Master is the highest among the Servants of this Great Holy Grail War. In the first place, it is dubious whether they even understand the fundamental duty of a Servant to “obey their Master”. To them, the present world isn’t somewhere to return to, but rather nothing more than a strange and unknown place… In other words, they hold no lingering affections for the world of the living.
Considering that, the compatibility between Jack and their former master Sagara Hyouma was pretty much the absolute worst possible—or rather, perhaps it is better to say that all magi have the worst compatibility with Jack. Rikudou Reika is the only Master that is compatible with the existence known as Jack.
After being sublimated by Jeanne’s hands and having their binding as an amalgamation of evil spirits collapse, they will never be summoned again. Even if the conditions are exactly the same next time, a different “Jack the Ripper” will merely be summoned.
