A spaceship is lost near the forbidden planet of Inferno II. Some years later, a second ship with a crew of nine gets there and encounters a monster that rapidly makes mince meat of most of them. The sole survivor, Makurou Kitazato, must destroy the monster before it can surprise a third ship that is already en route.

Three monsters, Bem, who looks like a gangster, Bero, who looks like a boy, and Bera, a witch, act as agents of justice, hoping that they will be allowed to become human. Several episodes involve them protecting a young boy. The style of animation is fairly distinctive, and the storylines not without interest. (Source: AniDB)
