Ume is a first year at Kimetsu Academy. She’s one of the school’s three beauties and has a lot of fans. She has an older sibling named Gyutaro, who’s a third year in the same school, an ISFP, and is ugly since he suffered from congenital syphilis. The two are known as the Delinquent Siblings. She’s an ESFP and known for being a mean girl, especially to those she saw as ugly. But when someone beats her up, she’s a crybaby.
