List of Hell Teacher: Jigoku Sensei Nube characters

This is a list of characters from Hell Teacher: Jigoku Sensei Nube. It can be divided into several groups, each distinct from the others. The first group comprises the staff of Dōmori Elementary, consisting of teachers and other adults (mostly) who assist in the education and welfare of the students. It includes Nūbē, his "perverted obsession" Ritsuko Takahashi, other teachers, and the principal. The second group is the student body, with each student bringing a unique personality and set of experiences to their education, along with encounters with the supernatural. Most characters are students in Nūbē's class 5–3, but students in the fifth grade and other grades (such as Hiroshi's soccer teammates and Makoto's "girlfriend," Ai Shinozaki) are also included.

The third group comprises the various yōkai encountered by Nūbē and the citizens of Dōmori. Many of these spirits appear only once, while some make cameo appearances later when various spirits reappear, to the advantage or disadvantage of Nūbē and others. Some, like the yōko Tamamo and the yuki-onna Yukime, become intertwined in the events of Dōmori, either assisting or tormenting Nūbē as they see fit. The last group of characters consists of humans who do not quite fit into any of the other categories but are connected to the affairs of Nūbē or his students. This includes exorcists such as "itako-girl" Izuna Hazuki, the crooked Buddhist priest Oshō, and even the parents of the 5-3 students.
