Takeshi Motoba is Taihei Doma's childhood friend and coworker, his nickname is Bomber.
Unlike Taihei, Takeshi is laid back and lazy, similar to Umaru Doma. He likes to goof off at work, and mess around when out and about. 
Takeshi has been friends with Taihei since at least high school, and followed each other to work in the same office. Takeshi has a little sister, who is also friends with Umaru, Kirie Motoba. His relationship with his sister is violent, with her becoming furious with him after upsetting her. 


Umaru is a renowned beautiful 16-year-old girl, living with her elder brother Taihei. She's a perfect little sister: Popular, smart, kind-hearted, everybody admires her. So who would believe Umaru keeps a certain secret? Sleeping, gaming, watching TV, eating junk food, drinking cola… that's almost all she does at home, leaving all the housework to her brother.

Shorts included in the Blu-ray and DVD releases of the TV anime. They take place in a world with multiple Umaru-chans.

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–she 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. In this hilarious comedy about family, friendship, and the nonsense we put up with (from the people we love), Umaru and Taihei will find a way to make it work!

Note: The chapter count includes 14 extra chapters.

High-school beauty Umaru seems like the perfect teen wunderkind, but she's hiding a shocking double life. As soon as she gets home, she becomes a junk-food-inhaling, soda-guzzling, video-game-addicted slob. The only one who sees this unsavory side of Umaru is her beleaguered older brother Taihei, who does his best to keep up with his work while trying to get his little sister to behave like a decent member of society. As she makes new friends and gets into a number of wacky situations, Umaru will continue to fight for her right to stay up all night binging potato chips and anime. (Source: Anime News Network)
