Everyone's favorite two-faced little sister returns, complete with hamster hoodie and her big brother in tow! Umaru continues to hide her otaku nature from the world, pretending to be three different people over the course of an average week to keep her friends from learning her secrets. Her unfailingly tolerant brother Taihei continues to look after her, determined to do his best in the face of challenges like company trips, eccentric co-workers and his sister's video game addiction. Kind Ebina, passionate Kirie and energetic Sylphynford also return, keeping Umaru desperately scrambling to make sure each girl only sees the "face" she wants them to see!
