Taihei DOMA

Taihei Domo is a salaryman at Diamond Service company, where he works with his childhood friends Bomba and Kanau and his new co-worker Alex. At home he lives with his little sister Umaru, who runs him ragged with her wacky antics as he tries to cook, clean and keep order in their small household. He tends to be oblivious to certain things around him, from his sister's manipulations to get him to do her bidding to the less-than-subtle romantic feelings that both Kanau and Nana Ebina seem to have for him.
