Berserker (バーサーカー, Bāsākā?) is a Berserker-class Servant able to be 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?).

During the Heian period, one of the Oni that appeared on the imperial capital and exhaustively carried out atrocities. Regarded as a subordinate of the Shuten-douji that lived in Mt. Ooe, it has been said that - during the "oni extermination of Mt. Ooe" by Minamoto no Raikou and her Four Heavenly Kings - she crossed swords with Watanabe no Tsuna of the Four Heavenly Kings.

The sole survivor of Mt. Ooe's oni, she attacked Watanabe Tsuna on the Rashoumon (or the Ichijou-modoribashi) at the imperial capital and ended up having her arm cut off. While said arm was temporarily snatched away as a spoil of war, Ibaraki would later retrieve it and disappear to somewhere.[2]

In actual fact, she is not Shuten Douji's subordinate, but it is rather believed that Ibaraki Douji existed as "the ringleader of Mt. Ooe's oni". (Despite being a mighty existence, the extremely pleasure-seeking Shuten had no intentions of commanding the swarm of oni herself)[2]

The one who erected a solemn palace at Mt. Ooe, cherished Shuten Douji as a sworn brother, commanded a group of oni that were each a match for a thousand warriors and exerted tyranny on ancient Kyoto was Ibaraki Douji herself; a "raging oni" that made people fall into the depths of terror.[2]

Due her anecdotes and vestiges, she is classified as a "anti-hero".[2]


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


Her wish upon the Holy Grail is "to see the smiling face of Shuten." The smile of her stepsibling, one without worry, without sorrow, without hesitation, is the source of Ibaraki'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 smile even until her death.[1]


Her beloved stepsibling. 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 anyway.)[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]
Minamoto on the whole
Hate them. Will kill them all if they dare show their face.[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 mk.I. 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
Hatehatehatehatehatekillkillkillkillburnkillshredk illeatkill.[1]
But, occasionally would like to exchange words instead of swords. Raging intention to kill and sheer curiosity. A bit bewildered that two such conflicting thoughts resides within, but why... when telling Shuten this, she smiles and whispered "Finally Ibaraki too acts prim and demon-like". Why....?[1]
Hard to deal. One of the Great Monster, yet blending in within 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]

Demon of the Oni Kind (鬼種の魔, ?) is a Skill that represents the superpower as well as the demonic nature as an Oni. A mixed Skill of Natural Demon, Monstrous Strength, Charisma, Mana Burst and etc; but some adjustment has been applied to its effects in this work. There are many concerned examples in which the form of Mana Burst is "Heat". In Ibaraki's case, it is "Flames".[1][2] One blow from and oni 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]
