Butsu Zone

In 1975,a young orphan girl named Sachi protests against the planned destruction of the temple Saigan (her home) by the Minoura clan, who plans to build a hotel in its place. When one of the gangsters notices the statue of the Thousand-Hand Kannon within the temple, Sachi tells them that she will not allow anything to happen to the statue. In response, the gangsters laugh and threaten her, telling her that there is nothing the statue can do to save her. However, the Thousand-Hand Kannon comes to life, breaking the temple doors and attacking one of the gangsters. The statue shatters into pieces and inside it is a boy who tells them to lay their hands off Sachi, sending fear amongst the gangsters who then flee, vowing revenge. The boy introduces himself as Senju, the Thousand-Hand Kannon.

Senju, as an emissary of the buddha Kannon, has appeared in the human world to find and protect the reincarnation of the future Buddha, Miroku. Recognizing Sachi as Miroku, Senju reveals that it is his mission to accompany her to India where she will awaken and achieve enlightenment to save the world from destruction. However, they are inhibited by the Mara, forces that seek to pollute with earthly desires, and Buddha who believe that Senju is not strong enough to protect Sachi from harm.
