Umaru Doma is a model student who has a hidden side: when she gets home each day, she puts on her hamster hoodie and turns into a sluggish otaku fond of junk food. As Umaru continues these daily antics, the friendship between her and her classmates—Nana Ebina, Kirie Motoba, and Sylphinford Tachibana—deepens, and more and more interesting events begin to unfold. Of course, these events give rise to numerous 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!

Five dangerous "seeds" have been stolen from their vault in the world of Evergreen and taken to Earth. Natsuki, an agent of the Queen, has been sent to retrieve them. However, he cannot do this alone and enlists the aid of Chihaya, a middle school student, who is "the only one" who can help him. With his aid she transforms into Magical Warrior Carmine in order to save the humans possessed by the seeds. Questions abound though, such as why Chihaya's mother appears to know all about this secret activity, why Chihaya remembers her father who reportedly died before her birth, and why she dreams of Evergreen, which she has never seen.

The strange incidents that happen with this family, which otherwise seems completely ordinary, will make you laugh out loud. The original manga is currently serialized in Takeshobo's Manga Club.
