Berserker of the Bakumatsu (幕末のバーサーカー, Bakumatsu no 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 Hijikata Toshizou (土方 歳三, Hijikata Toshizō), the Vice-Commander of the Shinsengumi, a security organization active around Kyoto during the Bakumatsu period, Hijikata Toshizou. Upholding strictly absolute discipline within the squad, he is a feared demon of a vice-captain even amongst the peerless swordsmen that are his squad-mates.

A samurai who threw away his pale blue haori, put on western clothing, picked up a gun and continued to fight against the changing era in order to follow through with his own truth.

Hijikata's life ended as the samurai was shot to death at Hakodate.

Although a Berserker, normal conversations are possible. Contrary to his demon-like fighting style, in the battlefield he is a pragmatist who also has the flexibility to employ any means necessary to win. When the Master that summoned him has given up to fight, he will instantly become a target for purging.

In battle he rages wildly like a devil yet retains his rational aspect as a tactician, a rare type of Berserker. The demonic vice-captain bearing the brand of loyalty ---Shinsengumi, advance!

A rare type of Berserker, who displays both the savagery of an Evil Spirit and the rational aspects of a tactician in battle.
