1x22 - Hell Teacher: Jigoku Sensei Nube

An incoming storm traps Miki and Hiroshi at the empty school with Nube. They watch in confusion as a car comes screeching into the schoolyard and a man and woman leap out, desperately searching for somewhere to hide. Realizing the gravity of the situation, Nube takes action, but it may be too late. A deadly game of hide-and-seek has already begun.
