Katou Hiroyuki

Faithful boy and childhood friend.

A very normal and fine young lad who is childhood friends with the heroine. He has a gentle and highly responsible personality, but is sensitive to the situation and a bit of a late-bloomer. He has been in a relationship with Saki since before her mother's remarriage.

He can't make much time for Saki due to him being busy with school club activities. He has no sexual experience aside from Saki, he cums fast and the girth of his penis is below average too.
