Hell Teacher: Jigoku Sensei Nube

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 television series adaptation produced by Studio Kai is set to premiere in July 2025.

A spin-off story for Izuna Hazuki the itako-girl, Reibaishi Izuna: The Spiritual Medium, was serialized in Oh Super Jump and later in Super Jump from July 2007 to October 2011. A sequel to the spin-off, titled Reibaishi Izuna: Ascension was published from November 2011 to June 2016. A direct manga sequel, titled Jigoku Sensei Nūbē Neo, was serialized across three Shueisha's magazines from May 2014 to December 2018. It is set ten years after the main story events, with Kyoko becoming a teacher at the Dōmori Elementary and Nūbē returning to the school from Kyushu. A sequel titled Jigoku Sensei Nūbē S was published in Saikyō Jump from August 2018 to April 2021. Another series, Jigoku Sensei Nube Kai, started in May 2025.

By July 2024, the overall manga franchise had over 29 million copies in circulation.
