Himouto! Umaru-chan (2015 anime)

Himouto! Umaru-chan is a very slice of life of a beautiful young high school girl that basically do all the otaku stuff and totally rely on his brother.. the show highlights her transformation between her otaku real true form and her perfect high school girl form. Although she hides her true form now and then, she is still very popular between her friends and have happy flags.. Really hoping for 2nd season.
