History Characters / HimoutoUmaruChan

* DitzyGenius: In her chibi form at home, at least. She [[BookSmart gets perfect grades at school]], but at home she's a lazy slacker who doesn't even know what an Internet router is (which, of course, she finds out the hard way—by spilling cola on it).

* BrilliantButLazy: Umaru gets perfect grades and is the top in every class at school, but she spends most of her off time lazing around and indulging in her otaku hobbies

* BrilliantButLazy: Umaru gets perfect grades and is the top in every class. But she spends most of her off time lazing around.

* DitzyGenius: In her chibi form at home, at least. She gets perfect grades, but at home she's a lazy slacker who doesn't even know what an Internet router is (which, of course, she finds out the hard way—by spilling cola on it).

* CatSmile: Her upper lip is constantly showing as one, which results in this as her default smile.

* ClosetGeek: Umaru is heavily invested in maintaining her outside image as a perfect, refined girl who claims she's not even allowed to read manga, while at home she's a lazy {{Otaku}} who's obsessed with anime and video games.

* {{Otaku}}: She is totally obsessed with anime and gaming merchandise, and hoards a pile of them at home. She doubles as an OtakuSurrogate, since most of the media she's into is typically aimed at a male audience, such as {{shonen|Demographic}} manga and FPS games.

* MultiEthnicName: Her given name is (supposed to be) German, her surname is Japanese.

* MultiEthnicName: Same deal as his little sister's.

* {{Otaku}}: She is totally obsessed with anime and gaming merchandise, and hoards a pile of them at home. She doubles as an OtakuSurrogate, since most of the media she's into is typically aimed at a male audience, such as {{shonen|Demographic shonen}} manga and FPS games.

* {{Otaku}}: She is totally obsessed with anime and gaming merchandise, and hoards a pile of them at home.

* InexplicablyAwesome: There's no explanation for why Umaru can be best at everything, despite being a lazy bum who never puts in any effort. Likewise, it is unknown [[BeautyIsNeverTarnished how she can maintain her flawless beauty and perfect figure]], despite her unhealthily lifestyle and consumption of thousands of calories daily in snacks alone. Most baffling of all is how she straight up shape-shifts. One has to simply accept that common sense does not apply to Umaru.

* NeverGetsFat: Lives on a steady diet of soda, potato chips and various other unhealthy snack foods. Never gains so much as a pound.

* {{Keigo}}: Her speech is always very formal due to being an {{Ojou}} from a rich family.

* MaybeMagicMaybeMundane: Her "shape shifting" between her "outside" and "inside" forms are either a metaphorical artist's choice to reflect her very different behavior in public versus in private, or her physically shrinking and growing in size. There are certain scenes that really make it hard to believe she's supposed to be a fully grown teenage girl while in her chibi state.

* MaybeMagicMaybeMundane: Her 'shape shifting' between her outside and inside forms are either a metaphoric artist's choice or her physically shrinking and growing in size. There are certain scenes that really make it hard to believe she's still a fully grown teenage girl while in her chibi state.

* SlaveToPR: The only thing that can restrain Umaru's laziness and brattiness is her desire to be seen as perfect by everyone except her brother. Taihei tries exploiting this by spending as much time around Ebina as possible.

* ProfessionalVoiceDissonance: Her voice deliberately changes between her "outside" and "inside" personas. She sounds like a mature, proper teenage girl while "outside" in public, but when in private while "inside" her voice is more high-pitched and childish to reflect how immature she really is.

* SecretIdentityVocalShift: Her voice deliberately changes between her outside and inside personas. She sounds like a mature, proper teenage girl while "outside" in public, while in private her voice is more high-pitched and childish to reflect how immature she really is.

* TohokuRegionalAccent: She occasionally slips into her native accent, having originally come from Akita.

* GagBoobs: Ebina's breasts are so big that when she moved to Tokyo, she noticed no one looked her in the eye because they were too busy looking down there, [[DCupDistress much to her discomfort]].

* ChristmasCake: Kanau has known Taihei and Bomber since high school, and it's been ten years since then.

* JapanesePoliteness: Speaks and addresses everyone very formally.

* {{Ojou}}: Speaks like one.
* SpockSpeak: Very well-spoken at all times.
* SpoiledSweet: Despite being incredibly rich and having a rather intense competitive streak with Umaru, she's a complete sweetheart to pretty much everyone around her--including Umaru.
