Second Season confirmed for…October 10, 2007
Sayonara Zetsubou Sensei! Good news I say… or better guess, because I still haven’t finished the first season. The release of the fansubs is rather slow at the moment. I really like what I’ve seen so far though.

Sayonara Zetsubo Sensei manga will have a second season in Japan. The high school comedy centers around a pathologically depressed teacher who somehow finds the will to deal with a class of oddball students. The first 12 episodes ran from July to September of this year on Chiba TV and other stations, and the second season is planned for the beginning of 2008. Ten volumes of the manga, which began in 2005, are currently in print. Source: Ultimatum
