Sayonara, Zetsubou-Sensei #4

Argumento

Suicidally depressed high school teacher Zetsubou-sensei, a man for whom the light at the end of the tunnel is the coroner inspecting his glazed eyes, continues his attempt to endure life’s suffering while teaching a classful of cute girls. Will Kafuka Fuura, the most optimistic teenager on earth, ever convince her beloved sensei to look on the bright side of life? Or will Zetsubou and his students end up lobotomized and starving in a third-world dictatorship? All this, plus a Zetsubou-sensei Christmas!
