Ijigen Seitai Cyborg 0-ban
異次元生体サイボーグ0番
Description
Earth is being invaded by interdimensional monsters which they cannot hope to defeat until the accidental creation of Prototype Zero, a cyborg grown from the cells of the monsters but in human form. Prototype Zero is more than capable of defeating monsters one on one, but can we really be sure he's on the side of humanity?
