"I'll give you a good loving!"

- Kurumiya's discipline threat, on many occasions.

Synopsis
Kurumiya is the teacher of Year 1 Class A of the Purgatorium School of Rehabilitation. She has expressed some sadistic tendencies, although this is mainly during punishment, or discipline, of a student. Despite her instability and frequent mood swings towards her students, she is regarded as a good teacher, namely by Kamiya Kyousuke.

Appearance
Kurumiya is described on many occasions, namely by Kamiya Kyousuke, to be a typical loli. She wears a light-green name-brand suit and cap similar to an army uniform. She has pink hair and eyes, and is almost always seen brandishing or carrying a crude metal pipe. She has a cute face, heavily contrasting with her personality. Kyousuke has compared her to Maina on a few occasions, finding them similar in their child-like looks and traits, although the traits are shown more openly in Maina than Kurumiya.
