Нодзому Итосики всегда в отчаянии! Даже такие обыденные вещи, как плата за проезд в метро, могут погрузить его в глубочайшие пучины депрессии, из которой может вывести только попытка самоубийства. Как ни странно, Нодзому — учитель старшей школы, а его класс заполнен учениками, чьи проблемы даже более волнующие, чем его.

Nozomu Itoshiki is a high school teacher so pessimistic that even the smallest of misfortunes can send him into a pit of raging despair; some of these "catastrophes" even lead to suicide attempts. Sayonara Zetsubou Sensei is a satirical slice-of-life comedy set in the modern day, covering various aspects of Japanese life and culture through Nozomu and his interactions with his students: Kiri Komori, a recluse who refuses to leave the school; Abiru Kobushi, an enigma who frequently arrives to class with severe and mysterious injuries; the hyper-optimistic Kafuuka Fuura, Nozomu's polar opposite; and several other unusual girls, all of whom are just as eccentric as their teacher.
