Houjou Souun

Houjou Souun is the current leader of the Houjou House, which means he is currently the strongest master of the Yin Yang way. He works very hard understanding and solving various issues faced by JAPAN. He is very serious and has a very strong sense of responsibility.

He and Nanjo Ran are in love with each other, but Souun's dedication to his work often gets in the way.

He is a virgin, and very shy about the prospect of sex.

His relationship with Rance is an interesting one, as though Rance frequently mocks his virginity, he seems to have no problem spending time with him casually, which is quite a feat for a man.
