Kanoko Mamiya

Hime's classmate. She has known Hime since middle school. She became suspicious when Hime secretly worked at a café and visited Liebe Girls' Academy. This led to trouble when she couldn't understand Hime's behavior as a staff member, which eventually resulted in her working at Liebe Girls' Academy. She removes her glasses while working. She is one of the few people who knows that Hime's usual behavior is an act.

She has romantic feelings for Hime but has no intention of expressing them. She is not very good at conversing with people other than Hime. She initially had a sense of discomfort towards Sumika, but after various twists and turns, they became like sisters. Since then, she has shown more favorable attitudes towards Sumika.

With Youko's advice, she becomes Sumika's girlfriend. Later, she confesses this to Sumika and, as an apology for betraying her, tells her that she can do whatever she wants with her body, showing a tendency to blame herself excessively.

In middle school, she secretly gave Hime a love letter without revealing her identity. Before she could confess it was her, she realized there was no chance, so she decided to prioritize her "special relationship" with Hime. She is jealous of Mitsuki, who has already confessed and kissed, which is the opposite of her situation.

Her height is 156 cm.
