I don't have a lot of free time so I drop anime easily.
The ones in the picture are Popee the Performer, Happy Tree friends, Usami, and Usavich.

If you're into Japanese literature and was introduced to it by anime like I was, you may like these classical Japanese books:
- I am a Cat by Natsume Soseki (Comedy, Slice of Life)
- No Longer Human by Osamu Dazai (Tragedy)
- 10 Billion Days and 100 Billion Nights by Ryu Mitsuse (Sci-fi)
