Maki Zenin is a second-year at Tokyo Metropolitan Curse Technical College. She is from the Main Family of House Zenin, one of the "Prominent Three Families" of Sorcerers. Due to a Heavenly Restriction, Maki possess a very low level of cursed energy, comparable to the average non-sorcerer. As a trade-off for her low cursed energy, Maki has superhuman physical prowess.
After the death of her sister, Maki lost all of her cursed energy which is shared by twins. This completed her Heavenly Restriction, making her immensely more powerful.
