Enter the world of the junkyard, where rival tribes fight an endless war - vying for supremacy and the right to ascend to nirvana. Everything begins to change when a blinding light interrupts a skirmish between two tribes. Serph, leader of the Embryon, awakens after the flash to find that his opponents have been violently slain. In a crater left behind lies a young girl with black hair.
The people of the junkyard soon discover the effects of the mysterious light; tribe members transform into demons, and feed an insatiable hunger by devouring their enemies. Along with this new "Atma" comes another strange power: emotion.
Soon afer, the Karma temple issues a new law: "Devour the other tribes and bring the black-haired girl to Nirvana." Hostility only grows, as the tribes renew their efforts with increased hatred and zeal.
The Embryon struggle to defeat the opposition and protect Sera, the young girl, who may just hold the key to everything...
