Born on December 28, 1967, Kotomine Kirei stands at a height of 185 cm in Fate/Zero and 193 cm in Fate/stay night. He weighs 82 kg and has blood type B. His likes include misfortune, while he dislikes trust. A famous quote of his is: "People cannot change the past. All we can do is accept our own actions. If you still wish to be burdened by your sins, let it show in your future actions. It is your choice how to perceive something that has already happened."
Kotomine Kirei serves as the overseer of the Holy Grail War and resides in the church atop the hill. Known for his callous and sarcastic demeanor, he is also highly knowledgeable. As the supervisor, his responsibilities include enforcing the rules of the Holy Grail War, covering up any incidents that could expose the War to the public, and providing sanctuary to Masters who drop out. Both Tohsaka and Shirou seem to detest him, but their dislike doesn't appear to be overly intense. Despite the rivalry between the Mage's Association and the Church, Kotomine belongs to both organizations, likely why he was chosen as the overseer.
Kotomine plays a significant role in all three routes of the story, but he features most prominently in the final route, Heaven's Feel, where he becomes actively involved early on.
