Jigoku Sensei Nube

Nube is a clumsy, easy-going and kind teacher, but he has a secret under the glove of his left hand. He has a monster hand and ability to sense ghosts and evil spirits. So, he will protect all of his dear students with his monster hand from all evil spirits. The series created in 1996 and has 49 episodes and 3 episodes for OAV. It has funny scenes but I suggest that, this is for teens to watch.
