GOKU SAYONARA ZETSUBOU SENSEI

A continuation of Zoku Sayonara Zetsubou Sensei, with more stories revolving around Nozomu Itoshiki, the extremely pessimistic or despairing teacher, and the students of class the 2-H, who are each hilariously abnormal in their own unique way except for the one relatively normal girl who hates being called normal.(Source: Anime News Network) — Description from AniList community (anilist.co).
