Maki Morishita is a student under Takeshi Kono.
Asuza Suzumiya is Maki's aunt. While Asuza wants to keep her profession as a porn star a secret from her, Maki was able to figure it out.
Despite being her teacher, she and Kono have a relationship similiar to a brother and sister. As such she tends to tease him about jerking off or punches him whenever he has perverted thoughts.
