Tooru Sanada

Tooru Sanada is Ryu's older brother by eight years and has been Chizuru's crush since childhood. Although he resembles Ryu physically, their personalities are nearly opposite. Mature and refreshing in manner, Tooru cares deeply for both Ryu and Chizuru and treats Chizuru like a younger sister, calling her "Chi" because he thinks she looks as though she is smiling when she says it.
