Assassin (アサシン, Asashin?) is a Assassin-class Servant 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]

Fate/Grand OrderEdit

Onigashima: The Demonic Fairy TaleEdit

Fuuma Koutarou first appears in this event.[3]

Shimosa Province: The Stage of Rivers of Blood and Mountains of CorpsesEdit

Fate/EXTRA Last EncoreEdit

He is summoned by an unknown female Master during the Moon Holy Grail War. After arriving in the second floor, they both get killed during a fight with Dan Blackmore and Archer.[4]


In the Shimosa Singularity, after Danzou entrusted him with the Magical Energy left to her by the first Fuuma, his power was greatly increased. In this state, Kotarou possesses more energy than most servants, however, he is still unable to equally match Caster of Limbo. Despite him being physically weaker, thanks to his mother's protection, Kotarou is capable of wounding Heroic Spirit Swordmaster with mere kunai.[5] However, even when fighting alongside Muramasa, they are unable to harm Shirou Amakusa.[6]

His Noble Phantasms are Immortal Chaos Brigade and Ogre Trance.

Class SkillsEdit

Presence Concealment (A+ Rank): A skill that suppresses one's presence as a Servant. By perfectly suppressing his presence, detection is next to impossible. However, as he moves in preparations to attack, the rank of this skill drops considerably.[1][2]

Personal SkillsEdit

Subversive Activities (B+ Rank): The ability to reduce the enemy's war potential in the preliminary stage before going to battle. An expert of traps. With this skill at B Rank, it is possible to disable close to 30 percent of the enemy forces before they advance. In Fuuma Kotarou's case, the more subordinates he has the more the damage ratio increases. However, the higher the ranking of this skill is the more one's spiritual status as a hero declines.[1][2]
Ninjutsu (A+++ Rank): Consist of intelligence gathering skills, combat techniques, larceny skills, torture techniques, and etc. utilized by ninjas. At A++, one can be said to be on the class of Iga and Koga's head. At A+++, one stands shoulder to shoulder among the legendary ninjas. The system is unique for each school, and almost no documents related to the Fuuma shinobi clan brought to ruin by the Tokugawa house, are left behind. This Heroic Spirit, the fifth head of the clan, is thought to be chosen by means of his true strength and competency.[1][2]
Afraid of Your Own Shadow (C Rank): A state that originates from soldiers of a defeated army being frightened simply from the sound of the wind, or the cry of the crane; from fear as the origin itself. As Fuuma Kotarou suppresses his presence and lays a surprise attack, by making use of his subordinates as if they are his own limb he is capable of intentionally reproducing the state of paranoia. The will to fight severely declines and all kinds of bad status effects are applied as a matter of course.[1][2]
