Assassin (アサシン?) is the Assassin-class Servant of Major Reiter in the Imperial Capital Holy Grail Strange Story of Fate/KOHA-ACE. He is also summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order.
Assassin's True Name is Okada Izou (岡田以蔵, Okada Izō?). One of the four great manslayers of the shogunate's closing days, holding the alias of 'Manslayer Izou (人斬り以蔵, Hitokiri Izou?)'. The Onoha Ittou Style, the Kyoushin Meichiri Style, the Jikishi Style and such, he learned various styles of swordplay. Involved with numerous assassinations, he was imprisoned and executed for his crimes.
Overly boastful of his own abilities, he has a tendency to look down on all other swordsmen, but reputed as 'One with the sword, swift and nimble as a falcon,' his sword arm was the genuine work of a genius. He has a heavy grudge against Ryoma after he betrayed him when he was alive and swore to get revenge on him when they meet again as Servants and kill him. He clearly doesn't like being mocked, or made fun of by others. In Fate/type Redline, when Tsukumo mocks him that any bum can become a Servant, he brutally beat her up for it.
Assassin initially portrays himself as Sakamoto Ryoma.
GUDAGUDA Teito Seihai KitanEdit
When soldiers from the Imperial Japanese Army attempt to storm Tsukumo Fujimiya's place and assassinate her, he intercepts and kills them. He muses that his Master was working with the army, but he doesn't care because their relationship was only temporary. He steals a hat from a soldier's corpse, then expresses disgust that such trash is what passes for an assassin nowadays. He then shocks Tsukumo, who didn't notice the commotion outside, by appearing right next to her. He introduced himself as Saber class and his true name is Sakamoto Ryoma to Tsukumo. He examines her hands and finds no Command Spells, so he says they will wait for the Servant and Master she was working with to come back. When he is distracted by his Master telling him that the Servant and Master were attacked, she tries to attack him with her liquid bombs, but he deflects them with his sword. Enraged, he slices off the fingers of her left hand, making her scream in agony. He tells her to shut up, punches her in the face, then demands to know the Servant's True Name.
After he heavily injures Tsukumo, he tells her that her buddies have abandoned her. He notices her breathing is getting lighter and knows she won’t make it. He later tortures Tsukumo by reopening her wounds on the blade of his sword and tells her a outsider won't last long in Holy Grail War alive. He tries persuade her that if she tells him Saber's True Name, he will let her live. When Tsukumo found out his true class and mocks him, he brutality kicks her in the stomach, pulls her side ponytail, and tells her he doesn't like being make fun of and he won't hold back just because she's a woman. When his Master tells him to stop hurting Tsukumo, he tells his Master to shut up and don't give him orders. He pieces her lung after she asks if he was a fan of the real Ryouma when he was alive. Assassin impatiently gives her one last chance to reveal Saber’s True Name or he will end her life. As he was about to finish her off, Saber and her Master arrive just in time to save Tsukumo and he is seen fighting Saber. He recognizes Saber's swordsmanship and calls her a wolf of Mibu. He later offer a deal to Saber’s Master, Kanata if he values Tsukumo’s life. He will let Tsukumo live if he uses one of his Command Seals to make Saber commit suicide. When Tsukumo tries to convince Kanata to abandon her and use the Holy Grail to grant her wish, Assassin pierces her right hand through her right shoulder and she loses conscious. Suddenly Assassin looks mildly surprised to see Kanata’s body is starting to fade further as he lose most of his left face, arm and leg. He has no idea what’s happening to him, but he doesn’t care as he calls him a loser like his Servant. He demands Kanata to finish his Servant off so it will save him some trouble.
Assassin declares himself to be of the Manslayer (人斬り, Hitokiri?) class. He has generally poor stats, his Mana and Luck are abysmal and his Strength, Noble Phantasm rank and especially Endurance are little better. His only decent stat is B-rank Agility, and this lackluster repertoire would immediately betray to any observing Masters that he is not a Saber, the so-called “strongest class.” He has B-rank Presence Concealment, making it extremely difficult, but not nigh-impossible to detect his presence. His first Personal Skill is Eye of the Mind (False) rank C, allowing calm analysis of battlefield conditions and consideration of multiple tactics even in the heat of combat. Second is Manslayer, a manifestation of his own practical combat style seeking victory over the truth of the blade (thus it is both strong and brittle). His final skill is One with the Sword, as Swift and Nimble as a Falcon. These were the words used to describe Izou’s sword while he was still in training during the Edo period. He often learned new styles, but always left halfway through. He considered every style to be beneath him, and in some ways they were, but because of this, he never learned any secret techniques nor acquired true mastery. He also claims to have the ability to copy the sword styles of others, which is manifested in his Noble Phantasm Settlement Sword.

Voice Actor: Hiroyuki Yoshino
Noble Phantasm: C
Eye of the Mind (False): C
Fencing as Swift as a Falcon: A
Presence Concealment: B
Type: Anti-Unit Magic Sword
One of the four most notable assassins of the Bakumatsu, known as "Hitokiri Izou".
Educated in several styles of kenjutsu, such as the Onoha Ittou-ryuu, the Kyoushin Meichi-ryuu and the Jikishi-ryuu. He got involved in many assassination cases and was imprisoned and executed as a consequence.
Prideful of his own talent, he has a tendency to look down on other swordsmen, but his skill with the sword - evaluated as a "fencing as swift as a falcon" - is that of a genuine genius.

"I am a hitokiri..."
Level 2 Bond
An expert of divine punishment, Okada Izou.
In Japanese history, the Bakumatsu is regarded as the era in which the deed of "cutting people with a blade" was performed the most. As a "hitokiri" who represents said era, the sword skill of Izou is comparable to the Saber Class despite him being an Assassin.
During his lifetime, his relationship with Ryouma could be described as that of friends and he even took up jobs as a bodyguard at Ryouma's request. However, due the trend of the times, the two would eventually part ways in a conclusive manner.
Level 3 Bond
- Hitokiri: A
A swordsmanship skill specialized in cutting down people.
A pragmatic swordsmanship that exists only for the sake of winning, it is unrelated to the mentality of a seeker of truth.
Therefore, it is strong and fragile.
Level 4 Bond
- Fencing as Swift as a Falcon: A
A phrase used to evaluate Izou's sword back during his period training on doujous in Edo.
Izou learned many schools of kenjutsu, but never attained full mastership in any of them due not practicing diligently and always leaving the doujou(1) midway.
The swordsmen of all schools, all doujou, appears as inferior in his eyes - and that was actually the case.
Level 5 Bond
Rank: None Type: Anti-Unit Magic Sword
Range: 1 Maximum Targets: 1 person
The heretic sword of Hitokiri Izou. A Noble Phantasm that allows him to reproduce any sword technique which he has seen as his own.
When he is first summoned, he only possesses those memorized during his previous life, but it is possible to attempt further strengthening by seeing new sword techniques after being summoned.
However, there are limits to the sword techniques that he can reproduce - not only they must be Anti-Unit, but is also impossible to reproduce those that rely on the special traits of a Noble Phantasm.
Level 5 Bond
Okada Izou, owner of an extraordinary talent for the sword that can imitate any swordsmanship just by seeing it.
Such fearsome natural talents caused Izou to be released in the Bakumatsu society as a matchless hitokiri.
Extolled as an expert of divine punishment, Izou could be described as a prominent assassin in Japanese history that was involved in many assassination cases, but that also prevented his accomplishment as a swordsman.
Due the trends of the times or maybe even fate, but how regrettable: a rare genius of the sword was unable to polish his talent and let it bloom exactly because he was a genius.
(1)it is kind of hard to translate properly, but the original Japanese wording implies that he studied in several different doujou during this period, but always transferred out before finishing his training.
(2)roughly, disposing sword".
