Female. Blue medium-length hair. Blue eyes. An incredibly beautiful girl. She emits an aura and is loved by God; everyone, regardless of gender or age, says "Offu" when they see her. Except Saiki. Because Saiki is the only one who doesn't say "Offu," she tried to make him blush out of pride, but eventually fell for him. High-handed on the inside, but kind and humble on the outside.
