Hell Army Z!

Kidō's team heads for Demon's Gate, where Hell Army Z is, to rescue Haruna. These guys want her to be a sacrifice to revive the demon lord. Of course, Kidō won't allow them to have their way with his sister, so a game is inevitable. But it soon becomes clear that the devils' monstrous power is too much for them and time is ticking. Will this be the end for Haruna?
