Himouto Umari Chan Graphic Novel Volume 13

In public, Umaru Doma appears to be the perfect high school student: hard-working, refined, and totally responsible. But the minute she gets home to her older brother Taihei - and dons her famous hamster hoodie - and devolves into the ultimate bratty little sister! She's happy to roll around all day in an otaku cloud of games and junk food while her exhausted older brother takes care of everything in the house.
