Kamiya Erina

A female student who harbors feelings for the protagonist. Though she speaks little, her sharp, incisive remarks stand out—a classic cool beauty.

Contrary to her appearance, she is a pure masochist, spending her days trembling (secretly) while being treated like a toy by the protagonist.

Simultaneously, she possesses a significant sadistic streak, occasionally revealing a merciless side toward others.

Though barely discernible, she harbors a faintly dark emotion deep within her heart toward Ayaka, who has become the protagonist's target.
