**Height:** 158 cm (5'2") At school, Renako acts bright and sociable. However, while she enjoys talking with her classmates, this is only a front, and her "true self" is gloomy and negative. In middle school, Renako declined an invitation to go out with her classmates, causing them to reject her. Renako spent the rest of middle school as a hikikomori as a result of this. Because of what happened to her in the past, she has trouble declining invitations and requests from her classmates.
