Assassin (アサシン, Asashin?) is an Assassin-class Servant able to be summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order.



Assassin's True Name is Katou Danzou (加藤段蔵, Katō Danzō?). A thief and spy whose name can be seen in the Kanazoushi and military sciences documents from the early Edo period—In other words, a ninja. Known by the alias “Flying Katou” and “Kite Katou”, while her activities in the Kai and Echigo Provinces has been reported, her origins and objectives are wrapped in mystery with various theories existing about it.[1]

There are legends about how Katou Danzou operated puppets, karakuri dolls, but those are legends derived from the fact that “Danzou herself was a karakuri doll”—so is the setting in this work.[1]

A ninja descended from the Fuuma, who were mostly active and flourished during the late Warring States period. However, her true identity is that of a karakuri doll manufactured by the sorcerer Kashin Koji. An artificial female ninja (kunoichi) molded with the cooperation of the first generation Fuuma Koutarou, and possessed no life as a human being. However, as a result of accomplishing many of her duties and being often talked about even in later literature, her existence was carved into human history as a Heroic Spirit.[1]



A karakuri ninja of few emotions, and is quite mechanical. A karakuri girl. She did not possess free will in her lifetime, and she was just a mechanical doll that just abided by the orders inputted into her—or so she defined herself. But upon being carved into human history as a Heroic Spirit and manifesting as a Servant working for the current world, she began to consider that maybe, she might be allowed to think - and have feelings - just like humans. She wants to do so, if she is allowed.[1]
