Aoi is a Ravant, an artificially created human with a limited lifespan. He works as a courier who traverses long distances in impossibly short periods of time, by crossing through the Jihai (wasteland), where supposedly nothing can live. When a delivery goes awry and the recipient tries to kill him, Aoi is rescued and taken to a town with an orphanage that isn't at all what it seems. Most of the kids there have some special, super-human ability. Will the people and children of this town be allies in Aoi's search for vengance... or an even greater threat?

Jihai was published in English by CMX Manga from February 17, 2009 to November 24, 2009.
