Humanoid Monster Bem

妖怪人間ベム

Youkai Ningen Bem

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)
