Rinko Akaishi

Rinko Akaishi is the mother of the story's main character, Kuroe, and tends to be rather overprotective of her daughter. In her daily life, she dedicates herself to biological research and is also a devoted superfan of the singer Mayumi Hamasaki. Throughout the story, she quietly watches over and supports Kuroe, who transforms into a giant monster whenever her emotions—such as those stirred by romance—run high.
