.Q: Regarding Kotomine Kirei's life, could you disclose more details? Such as at what age did he graduate from the seminary, and at what age did he become an Executor.
A: Because of his father, Risei, Kotomine had been working diligently as a Executor-in-training since an early age. He entered the seminary at the age of 22. In the same year, he received a second baptism to graduate from a trainee to a full Executor who could operate independently. However, while performing his duty of judging the heretics, he married. Kotomine voluntarily left his position in the seminary, and abandoned the path of becoming an official priest. After the death of his wife, he worked for the Assembly of the Eighth Sacrament, concentrating on training as an Executor. At the age of 28, he lost his father Risei, and was given the position of a priest, albeit unofficially.
