Riyo Washizu

Оригінальне ім’я: 鷲巣理世

The daughter of the head of the Washizu-gumi, a Tokyo yakuza group. A high school student. She stays holed up in her room outside of school, has no friends, and is shy and quiet. Her true nature is that of a "Yowara" (a person who gets aroused by seeing others in a weakened state). While her sexual desires tend to run wild, she also has a desire to stay within the bounds of morality.
