My Teacher

Yuuna Serizawa, a third-year student, holds a grudge against Ren, and tries sending him to Hell, but her request is obviously rejected by Ai. Serizawa is infatuated with Hone Onna and sees Ren as a rival. Hone Onna corrects her misunderstanding, offering a band-aid for her injured knee. Yuuna flaunts the same band-aid on her neck, showing off to her classmate, Kira Moroboshi, who bears a similar obsessive affection for Hone Onna. At school, when Moroboshi finds her shoes thrown into a dirty bucket, Serizawa blatantly lies that she did it under Hone Onna's instructions. Enraged, Moroboshi sends Serizawa to Hell. Later, she ironically announces that she is no longer after Hone Onna, but Wanyūdō.
