Karin Yuuki

Karin has short black hair and black eyes. When on missions, she wears a school uniform, but when seen outside of battle, she wears a maid outfit. She has a developed, toned body and has a tattoo in the back with the roman numeral "XIII" under a star in between what appears to be wings. Karin is usually seen with a long hammer and a sword placed horizontally across her lower back.
