Mai Zenin

Mai Zenin is a character in the Jujutsu Kaisen series. She was a second-year at student at Kyoto Jujutsu High, member of the Zenin clan, and the younger twin sister of Maki Zenin.

Mai was mistreated by the Zenin clan growing up only for being a girl with little talent for jujutsu. Mai was content with living under their thumb as a servant and would rather do chores than fight. In contrast, Maki wanted to spite the clan and work as a sorcerer. The repercussions of Maki's rebellion forced Mai to study to become a jujutsu sorcerer. Mai detested the grotesque work exorcising curses entails and resented Maki for essentially thrusting them both into that life.

Mai was an unwilling sorcerer who took out her frustrations on others, mainly her rivals and Maki. She has a snarky and rude personality due to her experiences. She’s crude and likes to boost her own ego. While Mai doesn’t particularly like Aoi Todo, she hangs around him to make herself look tougher than she is. Unlike how she treated the Tokyo students, Mai got along with her peers, for the most part, especially Momo Nishimiya and Kasumi Miwa. She also appears to be the only one who can tolerate Todo and was visibly disappointed with Mechamaru when he betrayed their group.
