Himouto! Umaru-chan OVA

Umaru Doma's carefully maintained reputation as a perfect student still vanishes the instant she steps through her front door. These extra days bring more of the contrast Taihei knows too well: outside, Umaru is graceful and admired; at home, she becomes a tiny hooded creature devoted to games, snacks, and avoiding effort. Friends and family keep disturbing that comfortable routine, leaving Umaru to protect both her secret and her laziness.
