Miyakawa-ke no Kuufuku

Miyakawa-ke is a spin off from the Lucky Star series featuring two of the very minor characters that appeared throughout the series. Similar art and style. 

Both of these are shows about the everyday lives of families consisting of sisters who are living together and they are both less than 5 minutes long. Miyakawa focuses on just two sisters, who are pretty poor. It is a spinoff of Lucky Star, so it has a similar feeling and artstyle and the amount of cute or funny moments. Plus, there are background cameos of the main characters. Both sisters play an important role, though it's more focused on the younger, more serious sister. Danchigai meanwhile is centered around a boy living with 4 sisters, all with a distinct and unique personality and it's more centered around that and how he's their punching bag, which is somewhat of a focus of the comedy. But it still has enough moments of the five being a family. that it's still a cute and fun watch. read more
