Berserker (バーサーカー, Bāsākā?) is a Berserker-class Servant summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order.



Berserker's True Name is Ibaraki-douji (茨木童子, Ibaraki-dōji?), one of the Oni that appeared in the Imperial Capital during the Heian period, exhaustively carrying out all manners of atrocities. It has been said that Ibaraki-douji is regarded as a subordinate of Shuten-douji who lived in Mount Ooe; during the "Oni Extermination of Mount Ooe" by Minamoto no Raikou and her Four Heavenly Kings, Ibaraki crossed swords with Watanabe no Tsuna of the Four Heavenly Kings.[1][2] Due to her anecdotes and vestiges, she is classified as an "Anti-Hero".[2]


In actual fact, Ibaraki-douji is not Shuten-douji's subordinate, but it is rather believed that she existed as "the ringleader of Mount Ooe's Onis" instead.[1][2]

Ibuki-douji, who was born from the Great God Ibuki of Mount Ibuki, that is, Yamata no Orochi, and a human. In other words, Shuten-douji. Indeed, it was only appropriate for Abe no Seimei, an authority of ancient Kyoto, to pay attention to such a being. However, the one who, in reality, lead over the Onis of Mount Ooe is none other than Ibaraki-douji.[1]

Despite being a mighty existence, the strong but extremely pleasure-seeking Shuten-douji had not even a bit of interest in commanding the swarm of Oni herself.[1][2] As far as Shuten is concerned, the only one who could lead the bunch of Oni that were being drawn to her position as the "master who controls the mouintain" is her equal, Ibaraki-douji, and no other.[1]

The one who erected a solemnly majestic palace at Mount Ooe, who had cherished the pleasure-seeking Shuten-douji as her "sworn sibling brought up together with her", who had commanded a group of Oni that were each a match for a thousand warriors, and who had exerted tyranny on ancient Kyoto, had been Ibaraki-douji herself; a "raging Oni" who had made the people fall into the depths of terror.[1][2]

Ibaraki-douji's status as an Oni is highly ranked; a sharp-witted and fierce commander whose strong point is guerilla warfare. If one thinks about it, together with her army of Oni, she should have crushed any kind of strength from the humans, even if it is Raikou and her Four Heavenly Kings. (Or at least that's what she thought.)[1]

The one thing that tore down Ibaraki-douji's stronghold is none other than the pleasure of Shuten-douji's, her sworn sibling who she should love more than anything. For the sake of speaking with Sakata Kintoki, Shuten had guided Raikou and the Four Heavenly Kings into her stronghold, and even while knowing it was poison, she had drank the Providential Oni Poison. It was the height of pleasure for Shuten-douji. And Ibaraki-douji failed to stop her.[1]

The sole survivor of Mount Ooe's Onis, Ibaraki-douji attacked Watanabe no Tsuna on the Rashoumon (or perhaps the bridge of Ichijou-modoribashi) at the Imperial Capital and ended up having her arm cut off. While said arm was then temporarily snatched away as a spoil of war, Ibaraki-douji would manage to later retrieve it and then disappeared to somewhere.[1][2]


A blond haired girl with scarlet blood eyes.[1] In the anecdote of the Rashoumon, Ibaraki-douji appeared in the figure of a "beautiful woman".[1][2] 

Ibaraki-douji is a rather short Servant. Her hair is light yellow, with two curled bangs on the sides of her head and cut straight after reaching her thighs. Ibaraki-douji's eyes are of a glimmering gold. The ears are pointed and the earrings she wears resemble black beads. Her horns protrude right out of her forehead, going from black to red. Ibaraki's outfit seems to be a loosely worn, short-skirted yukata with a white, low-cut undershirt. Her yukata, of the same color as her hair, possesses long extensions on her sleeves, decorated with a multi-colored floral pattern. Outside the yukata, she wears a string of large black beads, resembling those of her earrings, while on the inside, she wears a wine-colored sash, tied into a bow on her back, with a yellow hexagonal pattern on each end. With her yukata worn loosely, her shoulders are exposed as a result.

Her nails are sharp like the talons of a beast, black by nature. Her hands and feet are of an unnatural blood-red, and slowly transitions into her pale skin in the form of tribal-like tattoos that reach from her hands to her shoulders and from her feet to below the knees. She is barefoot, but black strips are tied around the instep of each foot.

Her signature weapon is a great blade of bone that only the demonkin may hold. A mass of curses and grudges incomparable with the likes of swords made by iron.

In her second Ascension, Ibaraki-douji's head is decorated by a set of ribbons, and an additional sash is slumped over her left shoulder and covering her torso. Her hair also begins to turn into fire midway through.

In her third Ascension, her headwear gets a crown of feathers attached to it, a shimenawa-like rope appears around her waist, tied into a a knot, and the flames of her hair increased in length and took on the appearance of wings.


An Oni born in this world with an inhuman appearance. In her childhood, Ibaraki-douji was strictly disclipined by her mother, who descended from a noble bloodline, to learn how to hold pride as an Oni. Then again, when seen from the perspective of a third party, one cannot really see that Oni mother's training as something filled with love. Though it's pretty close to harassment.[1]

To summarize it, Ibaraki-douji is self-aware of her responsibility as the child of her noble mother, to have the last of the Onis, a kind being eradicated by humans, act as a group. In order to do that, Ibaraki established a standard rule, and for any of the Onis that break said rules, she would spank them with an iron staff. (Of course, Shuten is the sole exception.) She is a demon, so from the humans' viewpoints, she is unmistakably a wicked beast. But at her root, she is a belle who respects order and ponders over the fate of her brethren.[1]

While Ibaraki-douji's appearance exudes innocence, that very state of being is that of an Oni. Hurting humans, devouring humans, loving blood. However, she does not have much of a disposition in the way of selfishly enjoying slaughter and massacre. Her nature is not that of an Oni that brings disorder to the world; in the end, she devours humans as an Oni, as a living being. One can say that she is close to that of a wild animal. For example, even if she appears to be fascinated with sweets, her nature is indeed not that of a young human girl. Depending on the circumstances, she just might devour even the human who enticed her with sweets. Never ever take a lion for a cat. Never. Ever. Yet... If one actually succeeds on feeding her, she just might display a lovely smile.[1]

Ibaraki-douji's wish for the Holy Grail is "to see the smiling face of Shuten." The smile of her sworn sibling, one without worry, without sorrow, and without hesitation, is indeed the source of Ibaraki-douji's everything. Be it the famed-in-Kyoto Abe no Seimei, or Minamoto no Raikou, or her powerful Four Heavenly Kings, Ibaraki is unperturbed in her opposition against all of them, wishing only for that single smile even unto her death.[1][2]


Ibaraki-douji's beloved sworn sibling. She feels happiness when Shuten is besides her, but on the other hand, Ibaraki does understand that it was being with Shuten that brought ruin to Mount Ooe. She had abandoned her Oni subordinates for her love for Shuten, completely running counter to her mother's precept. Due to that, Ibaraki-douji conceals her feelings of friendship and affection for Shuten-douji. (Or so she thought anyways.)[1]
Minamoto no Raikou
"Hate her. Just once, I want to kill her, just once, but there's just no way against that one."[1]
The Minamoto as a whole
"Hate them. Will kill them all if they dare show their faces."[1]
Sakata Kintoki (Berserker)
"Hate him. Even killing him twice won't be enough. If you go to the point of almost killing someone, it would be as if you've already committed the act anyway, no?"[1]
Sakata Kintoki (Rider)
"Hate him. But at least his steel horse is not half bad. Heard that it is a dreadful steel bear known as the GOLDEN HUGE BEAR MkI. With that kind of name, of course I will feel curious."[1]
Abe no Seimei
"Hate him. Even killing him thrice won't be enough."[1]
Watanabe no Tsuna
But, Ibaraki occasionally would like to exchange words instead of swords. A raging intention to kill, and sheer curiosity. A bit bewildered that two such conflicting thoughts resides within her, but why... when telling Shuten this, she smiles and whispered "Finally, Ibaraki acts prim and demon-like too." Why...?[1]
Hard to deal with. One of the Great Monsters, yet blending in with the human world. Just reminiscing about it is scary enough already.[1]
Robin Hood
"Sage of the forest. He was ostracized out by his village. Maybe I shall keep this forest dwelling sage company."[1]


Fate/Grand OrderEdit

Rashoumon: The Devilish Capital of Restless Spirits and Drunken DreamsEdit

Ibraraki Douji is the main antagonist of this event. Having stolen Shuten Douji's strength in her sleep, she wrecks havoc amongst the villages around her. The protagonist must fight her multiple times in a raid to weaken her and finally beat her with the assistance of Sakata Kintoki (berserker).

Onigashima: The Demonic Fairy TaleEdit

Babylon: The Absolute Frontline in the War Against the Demonic BeastsEdit

Ibaraki-douji was summoned by Gilgamesh in Babylon, but Ibaraki had argued with Gilgamesh and betrayed him to become a bandit where she and her followers are constantly harassing the towns.[3]

Salomon: The Grand Time TempleEdit

Ibaraki-douji is amongst the "special events" Servants assisting Chaldea against the Demon Gods Pillars.[4]


  • Bone Sword (Unsigned) (骨刀(無銘), Kottō (Mumei)?)

In combat, Ibaraki-douji can perform slashes by means of a large war sword. The Bone Sword.[1] A sword not made by the metal tempered by the fires of hell, but thoroughly tempered over several hundreds of days using the bones of the Oni Kind, the firmest and most solid substance above land; a first-rate sword with an ominous aura wafting around it.[1][5] Unsigned.[1] Ibaraki claims it to be a great blade of bone only an Oni Kind can hold, a mass of curses and grudges incomparable with the likes of swords made by iron.[5]

Oni Kind Demon (鬼種の魔, Oni-shu no Ma?) is a Skill to represent the demonic nature and superpower of an Oni.[1][2] With the exception of Oni Kinds and mixed-race beings with Oni blood, one is not able to acquire this Skill.[1] It is a mixed Skill of the Mana Burst Skill, Charisma Skill, Monstrous Strength Skill, Natural Monster Skill, etc., but in Fate/Grand Order, the effects are adjusted. The form of Mana Burst is commonly associated with “Heat”. In the case of Ibaraki-douji, her Mana Burst becomes "Flames".[1][2] One blow from an Oni that is combining a high rank STR, Rank A Monstrous Strength and Rank A Mana Burst would result in an astounding amount of destructive force, devastating the target.[1]

Forms and Alternate VersionsEdit


Summer is here. Speaking of summer, there is the summer festival. Speaking of the festival, it's gorgeous, full of excitement, and there are lots of delicious stuff at the night fair. Indeed, it's not bad of an event at all.

...I noticed classes change when they swap into their summer attires. There were many Noble Phantasms that changed. Maybe mine changed as well.

I don't really understand the reason, but I shall try on this Saint Graph for now! Ibaraki Dōji enjoys the summer days to its fullest.

She is your same-as-always Ibaraki Dōji. It seems she didn't change too much in character. If you look from another angle, it's more or less whether if she is "somewhat in a good mood" or not. Pointing it out will surely get you bitten, yet this is strange to even Shuten Dōji. "She is squirmy and exhilirated, so much like a child. Have you ever loved the ocean this much?" Yet, Ibaraki doesn't bite.


Creation and ConceptionEdit

Hidari is the character illustrator for Ibaraki-douji.[1][2] Hikaru Sakurai and Kinoko Nasu are the scenario writers for her character.[1]

Comment from IllustratorEdit

"Ibaraki-douji's start is keeping her cuteness as much as I can while still keeping her unique part as an Oni, I think... The beginning concept was a deformed sort of gross-but-cute. Eventually what's left is only her hands and feet, her nonexistent eyebrow, and her long horns; but in the initial concept, she doesn't even have exactly 5 fingers. Her other body parts were finetuned and then it reached her current concept. The complete version is her second form, and from there, I made it simpler for her first form and add stuffs in for her last one. It was such a showy and luxurious design, so I had lots of fun drawing her."
