Kusanagi Shiyu

One of the Dragons of Earth, a member of the Japanese Self-Defense Force who is telepathically linked to the plants and animals of the Earth, and thus strongly resents humanity's pollution and destruction of the natural world. Although his punch carries the force of an earthquake, he is the least antisocial of the Dragons of Earth, and the least active in the destruction of Tokyo. He meets Yuzuriha (and is the first man she ever met who can see Inuki) and develops an affection for her; although she falls in love with him, his intentions remain platonic as she is still a child.

In Tsubasa Reservoir Chronicle
In Edonis country, he's a player paired up with Yuzuriha Nekoi. In Tokyo, he's one of the seven fighters of the City Hall faction.
