@karolat oh, too bad your site died.
Chio-chan no Tsuugakuro is so great, funny slice of life with a different humor. It could be summarized as the weird adventures of a gamer girl in her road to school.
Jashin-chan Dropkick is awesome too. Violent comedy, continuously breaking the fourth wall, and very cute girls.
Asobi Asobase, yeah another slice of life. Three girls playing different games after school. It may sound very generic but the comedy and characters make it very special.
