Kanaka, Saki and Ayuko are three girls who, as fate would have it, meet each other just before starting high school. Kanaka accidentally bumps into Ayuko, ruining the girl's ice cream cone, and their friendship soon follows! Together, the trio navigates high school life, whether giving each other nicknames, racing each other to class, or just having fun.
I think that if you liked either one of these animes you will like the other because they are about simular things 3 girls in school getting into a multiple of things. Also I think some of the characters they used are pretty similar in their personality. i.e. Saki = Yui
They are both comedy and school life so I think that you would enjoy both (even though Aiura is only 4 minutes long).
Yuyushiki and KINMOZA are two very funny slice-of-life/comedies based on 4-koma (4-panels manga). While the former doesn't have much of a story to tell and is definitely more formalaic than the other, they're both really similar in terms of humor and the amount of yuri-subtext they contain. If you happen to be a fan of the genre, put your yuri-goggles on and you shall not be disappointed by either Yuyushiki or Kin-iro Mosaic.
