Luna Tsukigase, first year high school student. At first glance, she seems like an innocent high school girl, but she is actually a ''former yankee.'' She used to be the head of a team and was known as ''Luna of the Moon Shadow,'' a legendary villainous Yankee with an undefeated record. Her dream is to become a model. For that reason, she retired from being a Yankee, hid her past self, and attempted auditions, but she keeps failing... The person who reached out to her was her tsundere handsome classmate, Itsuki Hinata.
