Higuma Kogane

A financially well-off girl who is the daughter of the president of a major toy manufacturer.

She is a very active, cheerful girl with as much energy as a supernatural being and a bright, dazzling smile loved by family, friends, and acquaintances alike. She might be a naive girl, but she also has a sadistic side to her, being stubborn and headstrong at times.

Just like the protagonist, she is a former student of the Fushizono Kindergarten and a member of the Rose class.
