Himouto! Umaru-chan - S01

Umaru Doma is a model student with a secret side: when she gets home each day, she puts on her hamster hoodie and becomes a lazy otaku who loves junk food. As Umaru keeps up these daily antics, her friendships with her classmates Nana Ebina, Kirie Motoba, and Sylphinford Tachibana grow deeper, and more and more interesting things start to happen. Of course, these events raise plenty of questions. What did Nana ask of Umaru's brother Taihei? Who is the mysterious girl with the diamond hairpin? And most important of all: why does this girl seem to know Umaru? These questions and more will be answered in Himouto! Umaru-chan R!
