Creation and conception In an interview with Alain Mendez and Mitsuru Uehira of Anime News Network, Japanese writer Gen Urobuchi had stated that Kirei's height in the original Fate/Stay Night visual novel was revised for Fate/Zero. Urobuchi regarded Kirei as the "last boss" of Fate/Stay Night. While Nasu had said that his strength came from his tenacity and numerous Command Seals. Urobuchi expressed that he got a headache from trying to come up with ideas for Kirei in the final climactic battle between him and Kiritsugu. He also explained that he had difficulties when writing about Kirei's Bajiquan. In Japanese, Kirei was voiced by the Japanese voice actor Jouji Nakata, while in the series' English dub, Kirei was voiced by Crispin Freeman. In an interview, Nakata noted that the scene in Fate/Stay Night: Heaven's Feel I. presage flower where Kirei ate mapo tofu at a Chinese restaurant "had an impact on fans of the original work" who "loved" the character.

Appearances Fate series

In Fate/Stay Night, Kirei Kotomine is introduced as a priest ostensibly acting as the impartial overseer of the "Holy Grail War", a battle royale among 7 participating mages (a.k.a. "Masters") who have harnessed the power of supernatural beings called "Servants". Due to his experience as an elite assassin for the Church, Kirei is an expert practitioner in Chinese martial arts whose proficiency is magnified by his immense physical strength and numerous Command Seals.Fate/complete material II: Character Material –– Characters: Kirei Kotomine, p.066-069. Nasu Kinoko & Takeuchi Takashi-Character Discussion.Takeuchi: Speaking of strength, who is stronger, Ciel or Kotomine?Nasu: Ciel is overwhelmingly strong due to her circuits, constitution, and immortality. The strength of Kotomine at the time of Zero was due to his abnormally large number of Command Spells and his tenacity towards Kiritsugu. It was truly the brightest moment of his life. The Kotomine at that time could even win against Ciel. He ultimately emerges as one of the series' main antagonists upon revealing he organized the present Grail War to manipulate its competing Masters into supplying Angra Mainyu, the destructive entity inside the "Holy Grail", with enough energy to be unleashed on humanity.

Fate/Zero At the time of his birth, Kirei Kotomine possessed Magical Circuits despite being of non-magus descent.Type-Moon.TYPE-MOON Fes. 10th Anniversary Event Official Pamphlet. 7 July 2012. "Q: Kirei's wife Ortensia is covered with wounds in the design draft, is it because she has a body similar to Caren's? Also, Command Spells appeared on Kirei due to the fact that he somehow possesses Magic Circuits despite being born in a non-magus lineage. Does this mean Caren also has Magic Circuits? A: Kirei's wife is an albino, and is immunodeficient. As a result, she can die from even a tiny wound, thus her body appears tattered. What Caren inherited is the aspect of 'prone to be plagued by illnesses'. This is truly an ordeal given by God.About the Magic Circuits, a normal person rarely acquires Magic Circuits. You can consider such cases sudden mutations. However, Kirei is not of this type. Kirei's Circuits were a gift from the divine sacrament, rewarding his father Risei's years of pious worship. Kirei was born with 'the right to recreate the miracles in the divine sacrament'. This 'right', in other words, was the Magic Circuits. Caren did not inherit the Circuits." While possessing a strong moral compass, Kirei discovered early in his youth that he could only experience joy through others' suffering.Type-Moon. "interlude 15-4: Death of a saint". Fate/Stay Night: Heaven's Feel. Day 15 – limited."Defective from birth —— The man [i.e. Kirei Kotomine] did everything he could after accepting the fact. He couldn't understand morals, but had common sense. So his teenage years were spent trying to overcome his defect. But it never happened. The man's purgatories and sufferings were entirely useless. And his final attempt was a woman....The man chose a woman with no future. She was terminally ill, only expected to live for a few years. Did he choose her because of that, or was that his only choice? He still doesn't know. Their life together lasted for about two years. The man tried to love the woman. The woman tried to love the man, did love him, and even had his child. But the result didn't change. It was because the man derived his happiness from the woman's suffering and his child's despair. The more he tried to love, the more their suffering saved him. The contradiction didn't make the man suffer. He doesn't even know if he suffered. But the more the woman tried to cure him, the more he wanted to see her grieve. The woman was a saint. She was sickly, but she was still a saint for him. It need not be said how faithful she was or how deeply she understood his anger. That's why the man was in despair. No human will ever understand him and try to heal him to her degree. And this woman still could not fill the void.Then —— there was no need to live and question right and wrong. He was born defective...."Type-Moon. "To Angra Manyu / All evils of the world." Fate/Stay Night: Heaven's Feel. Day 16 - FINALKirei Kotomine: "—— Emiya Shirou. As you feel supreme bliss in others' happiness. I feel supreme bliss in others' unhappiness.....I envy you people. What I sought, but could not obtain. What I obtained, but could not obtain. Many things slipped out between my fingers, no matter what commandment I used. What other people called happiness —— Did not bring me any joy." During the events of Fate/Zero, Kirei apprenticed himself to Tokiomi Tōsaka at his father's behest in order to secretly serve as his spy and ally against the other Masters in the Fourth Holy Grail War based in Fuyuki. Over the course of the war, he became obsessed with another Master, Kiritsugu Emiya, whom he grew to despise for taking his own humanity for granted and consciously suppressing it in pursuit of lofty ideals. After murdering Tokiomi and forming a contract with his "Archer" Servant, Gilgamesh, Kirei resolved to destroy not only Kiritsugu but the dream he had dedicated his life to as well. In a climactic duel to the death, Kiritsugu ultimately defeated the vengeful priest, leaving him fatally wounded. Nevertheless, Kirei was able to make a wish upon the cursed "Holy Grail" that resulted in much of Fuyuki's destruction.Type-Moon. "Go along the cheek / Conflict / That which cannot be surrendered." Fate/Stay Night: Fate. Day 15 - Utopia.Saber: "Answer me. Why does Archer still remain? What caused that fire? Why are you still alive even after being beaten by Kiritsugu…!?...."Kirei Kotomine: "I do not even need to tell you. Ten years ago—the Holy Grail was incomplete but full, and it was possible to obtain it. I merely touched it. You and Kiritsugu were powerful, so I wished for a diversion to separate you two. But I was surprised by the diversion that occurred....."Saber: "—Then you caused that fire with the power of the Holy Grail…!?"Kirei Kotomine: "Who knows? I think the Holy Grail would have done the same thing even if I was someone else. It is a thing of that nature. People call it an omnipotent vessel, but only blood, darkness, and curses fill it. You saw it as well, right? The darkness that spilled out from it when you destroyed the Holy Grail...."Saber: "Nonsense. The Holy Grail is a magical vessel that grants the wishes of its possessor. That fire must have been your wish...!"Kirei: "Only the result. The process was not what I had in mind. I only wished for people to be gone from that place...I do not know about the original Holy Grail, but this Holy Grail is merely a vortex of power. It cannot make precise calculations or correct any inconsistencies. It is only pure power. It is like a great weapon. If the possessor wishes for great riches, it will kill everything around it to bring happiness to its possessor." Upon being revived by the Grail, Kirei committed his entire existence to freeing the dark power within it (i.e. Angra Mainyu).

Fate/Stay Night In the first route of Fate/stay night simply called Fate, Kirei Kotomine emerges as the story arc's main antagonist after kidnapping Illyasviel von Einzbern to use her as a vessel for the Grail's cursed contents. In the ensuing climax, Shirō Emiya ultimately defeats him by destroying his heart with the Azoth Sword. In the second route, Unlimited Blade Works, Kirei attempts to use Rin Tohsaka as the vessel for the Grail only to be killed by his Servant, Lancer, well before the story's conclusion. In the final route, Heaven's Feel, he serves as both a protagonist and one of the story's primary antagonists. By prolonging Sakura Matō's life Type-Moon."Set position / Rain."
