Seika's son, Shinichi, is a man who cannot suppress his sexual desires and is always masturbating. His room is littered with AVs and onaholes, and he indulges in self-pleasure whenever he has the chance. Seika's neighbor, 'Kohana Non,' is also someone with strong sexual desires. Because of her intense libido, she gets dumped by her fuck buddy. Even when trying to have phone sex, she gets rejected and ends up masturbating so intensely that it makes a slurping sound. Strangely enough, the strongest spear and shield are drawn to each other and end up living next door to each other.
