Otowa Ryouko

She is Kyou's younger sister and your typical housewife.

She loves her husband Takenori, a chef, with all her heart. In contrast to her sister, she is calm and sociable. She is always worried that people around her might misunderstand her sister, who does not talk as much as she should, and she tries to take care of her in any way she can.

She is also aware of her sister's loneliness now that she is on her own. Because of such careful consideration, Ippei was popular among the opposite sex. Therefore, although I am not as active as my older sister, I have had more sex than her. In this respect, she feels that her overly serious husband Takenori is a little lacking in some areas. Naturally, she doesn't usually show such things in public.
