Hell Teacher: Jigoku Sensei Nube (地獄先生ぬ〜べ〜, Jigoku Sensei Nūbē) is a Japanese manga series written by Shō Makura and illustrated by Takeshi Okano. It was serialized in Shueisha's shōnen manga magazine Weekly Shōnen Jump from August 1993 to May 1999, with its chapters collected in 31 tankōbon volumes. The series follows Meisuke Nueno, aka Nūbē, the homeroom teacher for Class 5–3 at Dōmori Elementary. More than a teacher, however, he is a skilled exorcist, protecting the town of Dōmori from supernatural threats with strength borrowed from a powerful demon sealed in his left hand—a technique he calls the Demon's Hand. A 49-episode anime television series by Toei Animation was broadcast on TV Asahi from April 1996 to August 1997. Three movies and three original video animation (OVA) episodes were released. A new anime adaptation is set to premiere in 2025.
