Story(4/10): There's is nothing much of a story,just step-siblings and their friends with their everyday lives Art(4/10): Its decent to be honest considering this is an 3min per ep anime Characters(7/10): Most of the characters are siblings pairs,one of each of the pair having sister/brother complex,but at a lesser extent. Sound(5/10):There arent much of background themes in this anime.The opening is just about 30 seconds long too.
Its an almost all-female cast anime,but that doesn't take anything away from enjoying it.

Overall(8/10):
Although it just took 40 mins to complete this anime,i really enjoyed it and recommend this if you want to lighten up your mood.
