Shinohara Toshio

Chief instructor at the swimming School.

He approached Ryouka when she was feeling down in the dumps and asked her about her business problems, which led to their intimacy.

Shinohara, proposes to Ryoka, but the relationship is at a standstill because her daughter Mizuki does not agree to the marriage.

Shinohara, a good sportsman, feels the same fetishism for swimming suits as most men do.

While his relationship with Ryoka is not progressing, he is a little perplexed by Mizuki's adoration and awareness of him as a man.
