Aoi Zenin sometimes thought he shouldn't have been born. His journey to being a first-grade sorcerer half- assed, and now he was stuck with his asshole cousin, Toji Zenin, for the rest of his life. Killing cursed spirits was hard. Growing up in the Zenin family was hard. Being a demon trapped in the body of a human twat was hard. Yes, Aoi Zenin thought he shouldn't have been born at all. Other agrees. But he would just have to roll with it.
