Sayonara, Zetsubou-Sensei

さよなら絶望先生

Nozomu Itoshiki, a high school teacher whose name reads as 'despair' in kanji, finds catastrophe in every corner of daily life and sinks into theatrical gloom over social norms, government policies, and misspelled signs alike. His polar opposite, the relentlessly optimistic student Kafuka Fuura, reinterprets every crisis as something positive. Classmates like hikikomori Kiri Komori and obsessive perfectionist Chiri Kitsu pile on their own fixations, turning each episode's topic — censorship, conformity, modern manners — into satirical chaos.
