Shuuichirou Kudou

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.

However, when Kohaku is called back to Heaven, they realize how much they're in love with him, and when he comes back he makes his wish - for Kohaku to stay with him. Shortly afterward, he dies unexpectedly from an unknown.
