A 1990 OVA that swings hard at genetic horror and doesn't flinch when bodies break. Scientists create monsters out of arrogance, then their own children have to burn it all down, and the show treats every death like a real cost, not a plot beat. Graphic, punishing, built for people who want their action wrapped in actual stakes.

Thirteen scientists once tried to harness genetic power by merging human and beast into a single hybrid. Years later, thirteen of their children are drawn into a war to reverse what their parents created. Shinichi, whose parent was among those scientists, joins forces with Christian super-beings in an effort to save the world. Across three OVA episodes, the story blends action with dark fantasy.
