Kyosuke is the head doctor of the village clinic. Despite his young age and the fact that he has a severe maid fetish, he is highly respected in the community. He cheerfully makes house calls and seems to truly care about everyone's health. He has (half-jokingly) admitted that he wishes to marry Satoko when she is older, but is not above chasing after Rika when she is wearing one of the uniforms from the restaurant Angel Mort. In addition, he is the manager of the village's baseball little league team, the Hinamizawa Fighters.

Spoiler

In the past, he has performed lobotomies without consent, which led to him being banished from the medical academic society in Tokyo. He is recruited by Takano to direct research the Hinamizawa Syndrome, which he feels will redeem himself. It is later revealed that he works under Miyo in research, where he is trying to find a cure for Hinamizawa Syndrome, while not knowing of his employer's true desires.
