水沢 千里

The cheerful gym teacher of the school blessed with athleticism and swimming ability.

A beautiful woman with an active aura but with the sex appeal of a mature woman.
She gets along better with the students than with the other teachers. She also treats the protagonist neutrally.
Despite her sensual appearance, she's not good at anything sexual, and is clearly embarrassed when exposed to such things.

Chisato loves to gossip about the love lives of others, but her own is lacking considerably.
