Jigoku Sensei Nube

Nube is concerned about the presence of yokai in the school to which he was recently transferred, but the students make fun of him. Then, a bizarre event occurs during class.

The school festival is approaching. Nube's class decides to build a haunted house. Nube tries to help the students, but due to Tamamo's trap, he destroys their creation.

Ritsuko worries that Miki will get her into trouble someday due to Miki's addiction to social media. Meanwhile, a black shadow that has been sneaking into the high school possesses Miki.

Nube is concerned by the student's lack of an alarm as they now know of the existence of yokai in this world. In the meantime, Izuna tries to cast a certain spell but fails, which makes Miki's neck stretched.

Akira, who has not found his future dream, talks to a human anatomical model every day. It takes over Akira's body and spends only one day in Akira's body.

Ritsuko learns Nube's secret and her feelings toward him begins to grow. That night, Ritsuko is possessed by a yokai born from a woman's grudge.
