"Let me introduce myself, I'm Shirou Kotomine. This time, the grail... This wish is certainly right. That's why I have to make it happen. No matter how many lives will be trampled by it."
Shirou Kotomine (シロウ・コトミネ, Shirō Kotomine?) is the Master of Assassin of Red in the Great Holy Grail War of Fate/Apocrypha. It is unknown if he has any connection to Shirou Emiya or Kirei Kotomine of the Fate/stay night timeline.
Shirou was dispatched by the Church's Assembly of the Eighth Sacrament as one of the Masters of the Red Faction. He wants to make use of the Holy Grail War to fulfill his own wish.
Shirou appears to be a good-natured man with an innocent smile; he is in actuality a schemer who would destroy his adversary without the slightest hesitation in order to fulfill his own ambition.
He is sent by the Church to observe the Holy Grail War and to participate as one of the Masters of the Red Faction. He leads and controls all Masters of the Red Faction; however, when he suggested having all the Red Faction have a unified frontal offense, Kairi Sisigou was the only one to reject this.
He views the servant Ruler as the biggest obstacle and plans for her elimination by ordering Lancer of Red to kill her. He has been shown talking with his Servant and Caster of Red in one scene in the novel. Caster has actively worked alongside Shirou and Assassin and has called Shirou "Master.”
