Butsu Zone (series)

Butsu Zone (仏ゾーン) is a Japanese manga series written and illustrated by Hiroyuki Takei as his first series before Shaman King. It was serialized in Shueisha's Weekly Shōnen Jump from March to August 1997, with its chapters collected in three tankōbon volumes. "Buddha Zone" is the concept by which a Buddha can appear on Earth using a Buddha statue.

Plot
The series highlights the adventures of Senju (the Thousand-Hand Avalokiteśvara Bodhisattva) who has to find and protect Sachi, an incarnation of the Buddha Miroku (Maitreya Bodhisattva). Miroku is said to appear on Earth at a time when the Dharma is no longer taught and is completely forgotten, achieve complete enlightenment and then re-teach the pure dharma, becoming a successor of Śākyamuni Buddha, the founder of Buddhism. It is thus Senju's job to aid Miroku (Sachi) in achieving enlightenment, enabling her to achieve Buddha.
