Satou Yoshimi♀

Yoshimi is a second year student from class 2-C, Leo's classmate and a member of the student council. She is popular with everyone, she is an honour student, is quick in her movements, is a good cook, and is sweet-tempered. She puts the brakes on Erika once in a while, for Erika tends to go her own way without consulting anyone. She at first appears to be a very mature person, however, her true nature is quite the opposite. Erika is her close friend who understands her true self. She often approaches Leo, who does not notice Yoshimi's deep feelings for him.
