Leo is the heir to the Harwey family that owns the sixty percent of the wealth of the real world. He was conceived between the former Harwey head and Leo's biological mother Alicia (アリシア, Arishia?). Leo is the younger half brother of Julius B. Harwey who is unqualified to lead the Harwey family. When he was 3 years old, the Harwey family invested in him as he shows great potential. He underwent repeated surgery as a child, including a sound thaumaturgical process to burn knowledge directly into his brain. His mother spends less time with him as the Harwey shaping him to the ideal ruler. Julius was ordered to assassinate Alicia to help secure Leo's inheritance.
If the Holy Grail ends up in the hands of someone other than himself, the conflict that would have otherwise concluded in ten years would extend to twenty years. Even if a Master sent by the conglomerate emerges victorious, so long as the Holy Grail is "power on the national scale attained by an individual," it will become the kindling of conflict. In order to prevent that future, he himself went to the moon as a Master.
His avatar is a 14-year-old student. In the Near side, Leo wears a custom Tsukumihara Academy uniform. His orange uniform makes him stand out amongst the students. In the Far side, he wears the standard black uniform. This symbolizes the unification with the other students to escape the Far side.
In Last Encore, Leo possesses an older avatar that wears a beige trench coat.
Believing the Holy Grail to be potentially dangerous to humanity, Leo participates in the Holy Grail War to secure it. Confident in his abilities, he refers to his Servant Saber by his true name and does not make him hide his form around others. He doesn't concern himself with subtlety or tactics, instead letting something destined to be revealed happen without question. Victory is all but assured to him, as his superiority over others has been reinforced every day since he was born. Though he was raised to be a perfect ruler, he lacks normal human emotions, feeling despair for the first time only when he is defeated.
He is able to enthrall and enchant the entire class during the preliminaries with his regal bearing. He naturally seems better than those around him, as if he is naturally looking down upon them in his place as king. Like a prince, he has a natural charisma that draws people up to his level. His smile brings about the same sort of feeling as a warm and comforting sun rise, and his presence is inviting and inclusive. Any worries vanish and others begin to think of doing as he says, as if it is the only way.
Despite his overall kind disposition, just looking upon him brings about the Initial Protagonist's fight or flight instincts. Rather than kindness, he senses something malicious behind his appearance. The only ones to whom Leo does not address with honorifics are AIs and artificial lives of human make. His attitude towards Sakura Matou and Rani VIII can be taken as cold, but Leo is interacting with them in full earnest, with acknowledgement of their identities.
« Humanity will only exhaust itself even if it continues to change with no answer in mind. To find a new path for change before the world completely stagnates will doubtless be my next task. »
|(Leonardo Bistario Harwey)|
Leo himself is more aware than anyone that he was desired as a ruler and raised to be a ruler. A king is not someone who comes from the human world, but one who is sent by the heavens to the earth. Those who are born thus are said to possess regality. Leo's regality is "thorough ideal." One can say he is a lord of a level unattainable by the average person; someone who has overcome the contradiction of having discarded human feelings while full of humaneness, for the purpose of realizing a totalitarian society where people of unequal skills can live in equality. Though he has had no freedom since birth, that he nevertheless has a calm personality is no doubt his innate nature.
If Hakuno represents change and offense, then Leo is the character representing stagnation and defense. Leo possesses no self-interest and wishes for the world to stabilize under the watch of the Harweys. His goal in seeking the grail is not "greater power" but "certain stability." To Leo, what should be prioritized is humanity's continuation, not the reign of the Harweys. His ultimate goal in seeking the grail is a millennium of the next generation where people can live in safety. However Leo, who knows neither the negative emotions of the weak, of humans, nor defeat, at the same time does not know the emotion of fear, and is unable to even imagine the possibility of defeat. He will eventually come to know how distorted that is for a "human being." His way of accepting everything the way they are could not, even in his final moments, summon up the intrinsic essence of life, the vitality in the face of adversity.
Leo's deposition in the Far Side is different from his deposition in the Near Side. Leo frequently lapses into moments of childishness, such as when he insists Julius and Gawain give Hakuno a loud greeting when they first step into the student council room, and when he thoroughly enjoys himself when Rani orders Hakuno to strip, going so far as to request for a camera. His immaturity is also noticeable when he unintentionally uses inappropriate phrases when discussing women. He also casually informs Gawain of a harsh punishment in retaliation for a horribly cooked meal. Nevertheless, Leo is capable of being serious when the need arises, especially when it comes to BB.
Leo is introduced during the preliminaries, where he proclaims that his name will be known to all the world in time. He is not affected by the brainwashing effect, so he mostly takes his time to scout potential opponents like Rin Tohsaka and casually enjoy his school life, such as flirting with Taiga Fujimura by stating he would like her to visit his country.
His introduction begins to shift the state of the world and starts to tear down its repetitive nature. As he is the distinguished son of the Harwey plutocratic family, in a sense the person who will eventually rule the world, his presence in the school is strange to others. He takes Shinji's female followers and, unlike Shinji, helps them without showing any condescension. When Shinji begins to chide him, he apologizes with dignity for upsetting him without any hostility or resentment.
Towards the end of the preliminaries, he flirts with Taiga again before leaving, calling her a remarkable person that reminds him of the beauty of youth. He mentions that found the school to be an interesting and enjoyable experience, as he had never been able to attend one.
During the first week of the Holy Grail War, Leo is first met by Hakuno in the hallway with other Masters by Hakuno. He expresses his satisfaction to meet Hakuno again, then he has Saber introduce himself, having already stated their True Name without concern. Leo and Saber then take their leave after the latter's introduction, telling Hakuno to fight with pride and honor. He is soon encountered again in the library, where explains the nature of the school, area, and colisseum as Reality Marbles within the Moon Cell. As well, Leo explains that Masters gain entrance into the war if they figure out the false school life within four days during the preliminaries.
Leo is briefly seen during the second week having a conservation with Dan Blackmore. During their talk Leo reveals that he knows Dan was sent to the Moon Cell to retrieve the Holy Grail by the Queen. However, Leo proclaims that the Holy Grail is rightfully his as the heir of Harway family. After the two part ways Leo stops to congratulate Hakuno on their first victory.
During the third week, Leo and Hakuno catch a glimpse of the cyber ghost of Twice H. Pieceman. Leo then explains that the environment of SERAPH can allow the data of people stored in it to evolve into Psuedo lifeforms, which are just harmless data. After Hakuno defeated Alice and Caster, Leo consoles them on their guilt. He continues to say that he will claim the Holy Grail to end the world's suffering and bring Equalibrium to humanity. After Rin chastises the Harways for their desire to rule over humanity, Leo claims that his family will bring about prosperity. Rin claims that the rule of the Harways wil only bring stagnation to humanity, to which Leo states that all who do not support his family are considered to be expendable.
Leo encounters Hakuno again in the library during the 5th round where he reveals that Julius, Hakuno's current opponent, is his brother. He further reveals Julius' role is to protect him as the heir of the Harway family. While Leo firmly believes in his brother's victory, he states that whether Julius wins or not doesn't matter as he would eventually kill him, viewing Julius' death as the foundation of his rule. After Hakuno defeats Julius, Leo congratulates them on their victory, now viewing them as a worthy opponent that he looks forward to facing in battle.
In the sixh round, Leo examining the lapel badge that Hakuno found in the arena, reveals it be an altered version of Julius' badge. He further explains that Hakuno's opponent must have used it to lure them to him, and that they used its ability to access restricted to avoid Hakuno.
Like Rin and Rani, Leo fell into the Far Side upon the conclusion of the fifth week. Though his memories were sealed, even BB was unable to brainwash him, and he was trapped in the old school building. Unlike most Masters, Leo was able retain Gawain as his Servant. For the first half of the game, he leads the student council to escape from the Far side of the moon.
After Hakuno Kishinami defeated Karna and Jinako Karigiri, Leo and Gawain took action in Chapter Bad End. Gawain created a fire wall to prevent BB from harming Hakuno. Gawain fought BB but lost. Before BB could devour Gawain, Leo used all of his Command Spells to undo his contract with Gawain, sending Gawain back to the time before they had met. An enraged BB proceeded to kill Leo, but not before Leo passed on the leadership of the student council to Hakuno.
Fate/EXTRA Last Encore
Approximately nine hundred years ago, Leo lost to Hakuno Kishinami. Before his death, however, Twice H. Pieceman rescued Leo and passed on his belief that human history should be wiped out to Leo, whom he called the "King of the Land," and Leo accepted this belief whole heartedly. Leo subsequently agreed to become the seventh floor's Master, essentially becoming an enemy to humanity.
For several centuries, Leo maintained his post until he deemed no other Master was coming to challenge him and chose to go into a slumber, leaving his Servant Gawain to wait in his stead. During this time, Leo was able to travel to the first floor and interact with the Masters still part of the preliminaries. He is first shown beating the captain of the chess club, N.Amagi, at chess, while numerous other students watch while cheering for Leo.
Eventually, Leo was awakened from his slumber by Gawain due to the arrival of HAKUNO Kishinami, whom Leo easily identified as being a "mass of death", or Dead Face. He also recognized Saber and acknowledged Rin Tohsaka as coming from a family the Harweys were long-standing enemies with back on Earth.
Leo revealed that he no longer saw any purpose in humanity's continued existence and chose to allow its annihilation. This contradicts with his previous duty as being a savior, something HAKUNO points out. When HAKUNO reveals his desire to restore the Moon Cell, Leo chose to stand in HAKUNO's way and ordered Gawain to attack Saber.
Gawain's attack sent both HAKUNO and Saber plunging down to the first floor. Leo was convinced the two would not be able to return in time to stop Twice's plan and proceeded to attack Rin, but HAKUNO possessed a bookmark that enabled him and Saber to teleport back to the seventh floor in an instant. Gawain was defeated in the following rematch, leading Leo to let the pair advance forward to the next stage.
When Twice began attacking HAKUNO, Leo formed a shield that would grant him, HAKUNO, Saber and Rin time to form a strategy. Leo lamented that the real Leo had died the moment he agreed that humanity was better off annihilated. Leo believed that by opposing Twice he could at least restore hope to humanity, and summoned Gawain, asking him to offer the last of his strength.
Gawain launched his Noble Phantasm at Twice, successfully repelling the latter's attack. Drained of his energy, Gawain disappeared soon after. Leo, on the other hand, was struck by one of the Chakravartin's beams and was set aflame, but Leo accepted his death and smiled as he faded away.
He is the strongest Master who participated in the Holy Grail War whose every parameter is maxed out. Rin is superior in terms of offensive codecasts and Rani in terms of pure computational ability. However, even if they challenge Leo together, he still has the higher chance of victory. While Magus in the Fate/EXTRA universe do not possess the same abilities of their standard counterparts, Leo is noted for possessing several unnatural traits.
Firstly, he possesses an other worldly charisma, an air of superiority that causes others to gravitate towards him. This is likely a manifestation of the type of "Charisma" that great kings and leaders are known to have, especially amongst heroic spirits.
He was born with talents and was born with Magic Circuits. He was polished off by the Harweys' harsh yet careful education such as learning via sound magecraft. This likely included other processes in order to give him traits befitting the Harwey heir.

Leonardo Bistario Harway.
Strongest Master who participated in the Holy Grail War.
Ever-victorious king whose every parameter is maxed out.
(By the way, though Rin is superior in terms of offensive codecasts
and Rani in terms of pure computational ability,
even if Rin and Rani challenge Leo together, he still has the higher chance of victory)
Though it’s unimaginable from his youth and mild demeanor, he is the next successor of the rulers of the world, the Harways.
A king in the making who is the result of inborn talent (including Magic Circuits) polished off by the Harways' harsh yet careful education.
Leo himself is more aware than anyone that he was desired as a ruler and raised to be a ruler.
A king is not someone who comes from the human world,
but one who is sent by the heavens to the earth.
Those who are born thus are said to possess regality.
Leo’s regality is “thorough ideal.”
One can say he is a lord of a level unattainable by the average person; someone who has overcome the contradiction of having discarded human feelings while full of humaneness, for the purpose of realizing a totalitarian society where people of unequal skills can live in equality.
Though he has had no freedom since birth, that he nevertheless has a calm personality is no doubt his innate nature.
If we say the protagonist represents change, offense,
then Leo is the character representing stagnation, defense.
Leo possesses no self-interest and wishes for the world to stabilize under the watch of the Harways.
His goal in seeking the grail is not “greater power” but “certain stability.”
If the Holy Grail ends up in the hands of someone other than himself, the conflict that would have otherwise concluded in ten years would extend to twenty years.
…...Even if a Master sent by the conglomerate emerges victorious, so long as the Holy Grail is “power on the national scale attained by an individual,” it will become the kindling of conflict.
In order to prevent that future, he himself went to the moon as a Master.
“Humanity will only exhaust itself even if it continues to change with no answer in mind. To find a new path for change before the world completely stagnates will doubtless be my next task.”
So Leo narrates.
That “the current regime of the conglomerate is mistaken”.......Tohsaka Rin’s contention was a problem that Leo had already long since pondered over.
To put it this way, the one who prepares for the doom that comes after in view of the answer of this path is Leo.
Meanwhile, the one who fights in attempt to change that answer is Rin.
To Leo, what should be prioritized is humanity’s continuation, not the reign of the Harways.
His ultimate goal in seeking the grail is a millenium of the next generation where people can live in safety.
However―――Leo, who knows neither the negative emotions of the weak, of humans, nor defeat, at the same time does not know the emotion of fear, and is unable to even imagine the possibility of defeat.
He will eventually come to know how distorted that is for a “human being.”
His way of accepting everything the way they are could not, even in his final moments, summon up the intrinsic essence of life―――the vitality in the face of adversity.
A Master who also appears in CCC.
Like Rin and Rani, he fell into the Far Side upon the conclusion of the fifth week.
Though his memories were sealed, even BB was unable to brainwash him, and he was trapped in the old school building. (simply not being able to go out)
Even knowing that his memories are sealed away,
“I mean, it is a once-in-a-lifetime opportunity and all, so let us simply carry on like this!”
he responds optimistically.
Although upon being defeated by the protagonist in Extra he learns the truth that “he is not perfect,” thereby truly becoming a king, he is fated to perish in that very instant.
In the Far Side, the boy king who had been unable to even converse with the protagonist due to the difference in values, enjoyed his brief experience of youth.
By the way, the only ones to whom Leo does not address with honorifics are AIs and artificial lives of human make. His attitude towards Sakura and Rani can be taken as cold, but Leo is interacting with them in full earnest, with acknowledgement of their identities.
 Fate/EXTRA material - Encyclopedia: Sword Camelot [Codecast], p.197
Sword Camelot [Codecast]
A special type of codecast known as a “Finality”.
A secret spell that a renowned magus family passes down in its lineage.
Sword Camelot is the secret codecast of the Harways.
It’s a castle used so that two knights who value honor can determine who is the better of the two without the interference of interlopers.
The wall of flame encircling their surroundings cannot be destroyed unless it is by the welder of a holy sword who is against the duel.
Oh and that magic missile that a certain magic user used to destroy this reeeeally priceless relic ought to eventually fall in the category of Finalities.
