All 12 episodes of the comedy anime based on Sankaku Head's manga. At her high school, Umaru Doma (voice of Aimi Tanaka) is seen as a perfect student. But the real Umaru is only revealed after she gets home from school, whereupon she dons her hamster hoodie and settles back into the life of a lazy otaku. Whether she is lounging around with her friends or gorging herself on all the snacks she can find, it falls to her responsible brother Taihei (Kenji Nojima) to look after her and their home. The episodes are: 'Umaru and Onii-chan', 'Umaru and Ebina-chan', 'Umaru and Her Student', 'Umaru and Her Rival', 'Umaru and Summer Vacation', 'Umaru's Birthday', 'Umaru's Onii-chan', 'Umaru and Christmas and New Year's', 'Umaru and Valentine's', 'Umaru and Now and Once Upon a Time', 'Umaru's Days' and 'Umaru and Everyone'.
