Umaru Doma

Umaru Doma, alternatively Umaru in her indoor form, is the main protagonist of the Himouto! Umaru-chan series. She has an unknown ability to switch between two modes: an "outdoor" and "indoor" mode, the latter dubbing her as a "himouto" by her older brother, Taihei Doma. Umaru's 'outdoor' mode often draws attention by those who pass by her due to her attractiveness. She has pale skin with a slender figure and a small face with rosy cheeks and round, dark brown eyes. Her long, honey-blonde hair reaches her waist with two shorter strands framing each side of her face and short bangs covering her forehead. Occasionally, she wears her hair into a thin ponytail. At school, Umaru wears her school's typical uniform which consists of a long-sleeved, button-down white shirt tucked into a red pleated skirt, along with a thin, red ribbon around her neck and brown shoes. Unlike most other students, Umaru opts to wear thigh-high black stockings instead of the white knee socks. In the colder months, Umaru can also been seen wearing a maroon blazer with this uniform. Outside of school, Umaru often wears fashionable, frilly clothes that most girls her age are seen wearing. Her true form - her 'Indoor' mode - is the form of a toddler (and her voice and behavior are also like a toddler's), and is drawn in a chibi-like manner. This form is a representation of her childish, lazy, and messy, personality. She wears an orange hamster hoodie, a white long sleeve t-shirt, and berry-pink knee-length leggings while at home. This chibi form is sometimes referred to as her "hamster form". In the video arcade (as her "UMR" persona), she wears a black shirt and a crimson hoodie with brown khaki shorts and black thigh highs, with a crimson cap. She later wears a dark blue mask to hide her identity from Sylphynford. In all of her forms, her face also has very rosy cheeks. In her 'Outdoor' mode, she is described as the perfect teenage girl at school and around town. She is a student who is on top of her class (due to her outstanding grades), possesses an overall charismatic feel, kind-hearted, excels in everything she does, and despite her popularity, she remains humble, thus earning the admiration by her fellow classmates and faculty alike. She also portrays a very sweet and cute personality. Her voice is also calm, more feminine, and very refined. In her 'Indoor' mode, she is the exact opposite; she reverts to her true, chibi form, lets out her secret otaku side, and barely contributes in doing household chores (even taking care of her own hamsters), all of which she leaves to her older brother, Taihei. She is very messy,and lazy, eats junk food, drinks very large amounts of cola, and is obsessed with stuffed cat dolls, playing video games, reading manga, and watching anime, she usually refers to herself in the third person, She is also prone to whining/crying when things don't go her way, and behaves very strangely when not in public. In the video arcade, she is a well-known and feared gamer who goes by the initials "UMR".
