Kirishima Rikka

The second oldest daughter of the Kirishima family. She is the kind of person who likes teasing and annoying other people to entertain herself, but in reality, is pretty lonely. In the past, she turned down an offer of getting married from her fiancee, not to mention she is the only one of the siblings who lives by herself (in the next-door apartment).
