Mahou Tsukai Reimeiki

This series is the sequel to Grimoire of Zero. Seville is a student at a magic academy who remembers nothing before joining the school. Not understanding why he is there, time seems very long to him, especially since his grades are not great. One day, the headmaster of the institution sends him to promote magic in a region where witches are disliked. In a world where the war between the Church and witches ended many years ago, Seville will have to convince those who remain rooted in their prejudices.
