Emperor.

Fifteen-year-old Ars, due to psychological characteristics, spent most of his life at home. After moving with his mother to a small town, he decides to go to school. Ars faces a difficult path of socialization and verification of his moral beliefs. Due to the non-standard behavior and versatile hobbies of Ars, the initial rejection of classmates is replaced by interest and sympathy for him. Only the guy with the nickname Sissy hates Ars more and more, wanting to hurt him in every possible way, and, eventually, provokes him to a duel that will be a turning point for Ars.
