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



Assassin's True Name is Fuuma Kotarou (風魔 小太郎, Fūma Kotarō?), the fifth to bear this title and served successor of Houjou Souun - Ujitsuna. Their original name derives from that of their village, which was Kazama (風間, Fūma?), and they would normally earn provisions through hunting, lumberjacking and cultivating small fields. However, upon taking up a mission, they would call themselves "Fuuma" and have their dreadfulness become known across the land.[2]

Different from Japan's representative ninja, the Iga and Kuga, there are few reference documents about the Fuuma. The fact that the Houjou family which they served dissolved during the age of warring states is probably a big reason for that. Not even which kind of ninja tool the Fuuma used is certain.[2]

The same can be said about their origins; even what sort of circumstances brought them to settle in the Kazama Valley is unknown. One theory also says that they were an equestrian tribe that immigrated from the continent. They themselves would never reveal their origins. At any rate, they were feared by all people due to their terrific group tactics, and Fuuma Koutarou was their chief.[2]

Fuuma Koutarou is descended from foreigners and, at the same time, also has the blood of the Oni kind mixed in his veins. For the sake of surviving that turbulent war period, the clan performed a thorough match manipulation and gave birth to him as the greatest masterpiece of "shinobi" - the leader of the Fuuma. An inborn chief and shinobi, the Fuuma party would thus welcome one summit.[2]



The crucial Koutarou had a nature that was both compassionate and discreet; thus it was said that, while his body was a summit as a shinobi, his mentality was not fit for a shinobi and he spent his days secluded in his room.[2]
