Sayonara, Zetsubou-Sensei (Japanese: さよなら絶望先生, Hepburn: Sayonara Zetsubō Sensei, literally "Goodbye, Mr. Despair") is a Japanese manga series written and illustrated by Kōji Kumeta.
It was serialized in Kodansha's Weekly Shōnen Magazine from April 2005 to June 2012 and the chapters collected into 30 tankōbon volumes.
The series follows Nozomu Itoshiki, a teacher who takes all aspects of life, word, and culture in the most negative light possible. It satirizes politics, media, and Japanese society.
In 2007, the manga received the 31st Kodansha Manga Award in the shōnen category. The manga has been adapted into three anime television series and two sets of OVAs animated by Shaft between 2007 and 2010.
More crazy antics abound as Nozomu Itoshiki (a.k.a Zetsubou-sensei), who is the worlds most negative person, tries to teach class 2-F about how life is filled with despair and darkness.
A harder task than it first may seem, with his students being far from ordinary themselves, including the likes of the most positive girl he has ever met, his very own stalker, a foreign exchange student with split personalities and a perfectionist acting class president, due to the fact the real class president can't be seen by anyone, among others.
