Mei Hotarubi

Fighter Unit of Fearless First appeared in the manga in volume 5. Mei is looks to be a grade schooler about the same age as Ritsuka. She is actually a girl despite her boyish appearance and is very new to being a fighter unit so her word spells are weak. When she “tries” to fight Soubi it's really too cute. She has a crush on Mimuro and hates the way Nisei treats him. She wears her long hair under a cap, because she thinks that Mimuro is attracted to boys and would like her better that way. Mimuro wants their style of fighting to focus on the offensive, rather than defense. But Mei uses defense spells, because she doesn't want Mimuro to be hurt. Fearless has their names on the backs of one of their hands. Source: Angel Fire and Novellalive
