Shuuichirou Kudou 栩堂琇一郎

The first Shuichiro Kudo is a young doctor who rescues Kohaku from the tree where they are trapped. For this he is granted a wish, but isn't interested as he has everything he wants. Shuichiro is generally kind and trusting, but isn't one to seek other people's company - something that is remedied throughout the course of the story by the two angels, two demons and two servant demons who all move into his house.
