Nozomu Itoshiki is a high school teacher who always looks on the
negative side of life, constantly left in despair from the troublesome
issues society presents. He constantly tries to kill himself to free
himself from this cruel world, but is unable to do so because of his
class of students, many of whom are more bizarre than he is. There is
Chiru who needs to organize everything perfectly, the mute but abusive
Meru, Matoi who loves stalking people, and a host of other cute but
crazy students the most frightening of which is the optimistic but
oblivious Kafuka, whose enthusiasm is over-the-top and lethal to anyone
she meets. With all the antics his students carry on, can Nozomu ever
manage to find something good in life?
