Manga / Himouto! Umaru-chan

http://static.tvtropes.org/pmwiki/pub/images/i175025_4868.png
The Hot Gamer Chick.

Umaru Doma, age 16, is the perfect girl at school and around town; beautiful but with a kind heart, athletic, always gets high test scores, and while popular remains humble and is greatly admired by students and faculty alike, but...

Umaru at home is a barely functioning otaku slacker who lives with her white-collar worker brother, Taihei, who more or less caters to her every whim due to being easily nagged into things. Can Taihei fix his broken sister, who would rather eat junk food and play video games all night than go outside and play, or will his weak will allow her to become a complete shut-in?

Himouto! Umaru-chan (干物妹!うまるちゃん) is an ongoing 2013 manga series written and illustrated by Sankaku Head, with an anime adaptation directed by Masahiko Ohta for Dogakobo (Monthly Girls' Nozaki-kun and Plastic Memories) as part of the Summer 2015 Anime lineup.

Has a couple of spinoffs by the same mangaka, Himouto! Umaru-chan S, set in an Alternate Universe, and Akita Imokko! Ebina-chan, a prequel spotlighting Umaru's friend Ebina when she first arrives in Tokyo.


Tropes found in the manga:

  • Accent Relapse: Ebina will slip into her natural Akita dialect when excited or flustered, in her own mind if not out loud.
  • The Ace: Umaru is the kindest and most beautiful girl in town, is fluent at everything she does, has perfect scores at school and is beloved by all. As her secret identity U.M.R she's one of the best gamers in Japan. She achieves all this virtually effortlessly.
  • A Day in the Limelight: The last section of episode 5 focuses exclusively on Taihei and what he does at work. Umaru is only seen at the beginning and end of his day.
  • All Take and No Give: Umaru and Taihei's relationship is somewhere in the co-dependent area of the trope.
  • All Work vs. All Play: All-work Taihei spends nearly all his time at work or taking care of Umaru or the house, while all-play Umaru is a lazy bum.
  • Aloof Big Brother:
    • Inverted. Kirie is Bomber's aloof little sister. Bomber keeps trying to get closer to her, but Kirie is having none of it.
    • Played straight with Ebina and her older brother that left when she was 7.
  • Alternate Character Reading: Bomber's nickname comes from taking his surname, Motoba, changing the "moto" to "hon"note  and modifying the H into a B.
  • Ambiguous Situation: Chapter 89 ends with what seems like Ebina about to confess her love to Taihei. Chapter 90 begins next morning with Taihei and Umaru and no real hint of what happened as a result other than Taihei preparing New Year's money for Ebina when in previous years he only did so for Umaru. Chapter 92 mentions that he listened to it seriously, but doesn't elaborate any further. It isn't until chapter 98 where readers learn what actually happened: She didn't confess.
  • Animal Motifs: Hamster for Umaru. And not only when she's indoors—even when outside Umaru sometimes has rodent mannerisms, such as the way she licks ice cream.
  • Annoying Younger Sibling: At home, Umaru typically behaves like a Spoiled Brat who makes unreasonable demands to her older brother, Taihei.
  • Art Shift: Whenever Umaru switches between her outdoors persona and her indoors persona.
  • Author Avatar: Sankaku Head's avatar is the character with the white, cylindrical headnote  and hamster face. He pops up a lot in the anime, including in scene transitions, but special attention is drawn to him in the last episode, when Taihei is test-driving an SUV and freaks out over "nearly" hitting him while he was crossing a crosswalk, causing Taihei to shout "A MANGAKA!"
  • Aww, Look! They Really Do Love Each Other: Despite everything, Taihei and Umaru both get moments that show they care about each other.
  • Badly Battered Babysitter: This essentially sums up Taihei's home life.
  • Because You Were Nice to Me: Ebina has feelings for Taihei largely because he was the first person when she arrived in Tokyo to look her in the eyes, rather than focus on her large breasts. His politeness and friendliness also helped.
  • Beneath the Mask: Umaru looks to be mature, beautiful and sophisticated when outside her home. At home, however, she's a lazy, annoying, selfish brat.
  • Big Brother Worship: Sylphin thinks very highly of her older brother, Alex. She calls him "Onii-sama" and gets a breakdown when she thinks she'd made a fool of herself in front of him when she fought against U.M.R in a game tournament.
  • Big Eater: Umaru and Ebina.
  • Bishie Sparkle: Always appears with Umaru in public.
  • Bland-Name Product: Several. Zonama for Amazon, Gapcom for Capcom, Batsune Migu for Hatsune Miku, Jun piece for One Piece...
  • Book Dumb: Ebina always seems to get low test scores. Making it worse for her is that she's friends with Umaru, who is often the top ranking student on the tests.
  • Brilliant, but Lazy: Umaru gets perfect grades and is the top in every class. But she spends most of her off time lazing around.
  • But Not Too Foreign: Taihei's kouhai Alex, and Umaru's classmate Sylphin, are half-Caucasian. They are confirmed to be siblings in chapter 71.
  • Butt Monkey: Bomber.
  • Cannot Spit It Out: Kanau towards Taihei.
  • Cassandra Truth: Taihei tells Bomber in episode 7 that the "beautiful woman" walking and shopping with him is just his sister. Bomber doesn't believe it, stating that guys don't go grocery shopping with their sisters. Taihei seems shocked by this revelation.
  • Cat Smile: Sylphin sports one.
  • Christmas Cake: Kanau has known Taihei and Bomber since high school, and it's been ten years since then.
  • Christmas Episode: Episode 8 has one, along with New Years.
  • Clark Kenting:
    • When it looks like Kirie has discovered her double life, Umaru is able to fool her into thinking that her home self is actually her little sister "Komaru".
    • Umaru hides her identity for a game tournament by pulling on a domino mask and becoming "U.M.R." It convinces Sylphin, who recruits her to... help her beat Umaru. It also convinces Bomber, who's under the impression U.M.R. is a guy, much to Umaru's confusion.
    • Kirie fools her own brother during a trip to an aquarium by wearing a straw hat.
  • Clingy Jealous Girl:
    • Umaru is a downplayed version for her brother, but more out of annoyance that she doesn't have his undivided attention than any romantic feelings.
    • Kirie seems to act this way towards Umaru, often giving anyone paying too much attention to the latter a Death Glare.
    • Kanau doesn't seem very happy in episode 5 when she overhears that Taihei's homemade food was made by his girlfriend (the truth being that he made it). He then lies to his colleagues and says his younger sister makes them, prompting a sigh of relief from her.
  • Closet Geek: Umaru is heavily invested in maintaining her outside image.
  • Clueless Chick Magnet: Taihei having the affections of Ebina and Kanau.
  • Color Failure: Umaru and Taihei in Episode 2, after they realized that Ebina completely missed the former's tantrum over the latter refusing to buy her games due to enjoying her food at the restaurant.
  • Cool Big Bro:
    • Taihei is pretty much Umaru's father at this point, but he's very loving and caring towards her.
    • Bomber tries to be this, and while he doesn't fully fit it, it's obvious he deeply cares for Kirie and wants to be closer to her.
  • Country Mouse: Ebina, who hails from the Akita countryside.
  • Crazy Jealous Guy: Bomber uses this in chapter 34/episode 7 while eating at a restaurant with Taihei. He cries over meeting a woman at a mixer, only to find out she's already got a boyfriend. He then gives Taihei several Death Glare looks, and switches to a normal face while the waitress brings his food to the table. Then he complains that he's heard Taihei walking around with a beautiful woman, who he assumes is his girlfriend. When Taihei says it's just his sister, Bomber doesn't believe him at first.
  • Curtains Match the Window: When Sylphin appears in full color (such as in the anime or on tankōbon covers), she has blue hair and blue eyes.
  • Cute Clumsy Girl:
    • Ebina trips quite a bit.
    • Kanou, due to her young age and the stress that comes with her high position in the company, makes a lot of minor mistakes in work.
  • Cuteness Proximity:
    • Kirie and Bomber when around "Komaru", or Umaru at home.
    • Umaru when it comes to stuffed cat dolls.
    • Taihei around real cats. In episode 7 he follows one around for so long that he ends up in an unfamiliar neighborhood.
  • D-Cup Distress: Ebina's large breasts get a lot of unwanted attention. In a flashback during when she first arrived in Tokyo, people kept staring at them, making her very self-conscious as a result.
  • Declaration of Protection: While she has never actually said it out loud, Kirie has a good many Imagine Spots where she declares her intent to protect Umaru.
  • Deep-Immersion Gaming:
    • Used in the opening credits with Umaru.
    • Used again in episode 6 when Umaru, Kirie, and Taihei are all playing a video game version of Game of Life.
  • Defeat Means Friendship: This is revealed to be Sylphin's reason for wanting to compete with Umaru so much, since a defeated rival becomes a new ally. Apparently, though, this only applies when she is the victor.
  • Disqualification-Induced Victory: Umaru was going to lose pretty badly in a fighting game competition to Sylphin in chapter 52/episode 4. She then glances at her brother, prompting Sylphin to also do the same to see what Umaru was looking at. She sees her brother Alex standing next to him, and suddenly gets embarrassed, remembering how she'd been showing off, before running off the stage, giving Umaru the win by default.
  • "Do It Yourself" Theme Tune: Aimi Tanaka (Umaru) sings the opening theme solo, while she shares the ending song with Akari Kageyama (Ebina), Haruka Shiraishi (Kirie) and Yurina Furukawa (Sylphin).
  • Dogged Nice Girl: Kanau is incredibly kind to Taihei and has been after him since high school, but of course, due to having to bear with Umaru's every whim, he doesn't even realize.
  • The Dreaded: Played for Laughs with Umaru whenever she goes to the arcade. It's not that she's violent or anything; rather she often wins prizes with one token. This means the arcade actually loses money, as most people would typically fail at those games, and they wouldn't have to be replenished with new prizes. But since Umaru always wins at them in one try, they don't really make any money off her playing.
  • Early Installment Weirdness: In the "prototype" manga, Umaru is far more mean-spirited and childish than in the final version, doing things like like pinching Taihei's butt with a grabber arm toy, hitting him in the groin (though this is seemingly an accident), and making her classmates think that he's physically abusive by lying about an injury she inflicted on herself while throwing a tantrum. Additionally, "Indoor Umaru" isn't fully super-deformed, instead looking like a more realistic pre-teen girl.
  • Even the Girls Want Her: More than a few girls can be seen admiring Umaru along with the men. Then there's Kirie, who has a massive crush on Umaru.
    • Same with Ebina-chan, where at least as many girls are seen staring at her large breasts during her flashback, including the flight attendant.
  • Exotic Eye Designs: Sylphin Tachibana has flower-shaped pupils, as does her brother Alex when excited. It apparently runs in the family, as their mother also shows similar pupils when excited.
  • Extreme Doormat: Taihei can't say no to Umaru's whims and when he tries she'll nag and throw a tantrum until he concedes.
  • Face of a Thug: Kirie. It really doesn't help she's shy around strangers.
  • Foreshadowing: There are a lot of chapters that show Ebina reacting oddly to Umaru and Taihei bonding, later revealed to be because she hasn't seen her own big brother for a while and is looking for him.
  • Freeze-Frame Bonus: Near the end of Episode 3, Umaru has an Imagine Spot where she sees the ghosts from the horror movie she just watched. However, there is a very brief scene that shows the ghost boy, the ghost girl, and a ghost man/rapper moving around as if singing and dancing in a music video, and looking rather comical.
  • Friend to All Children: The shy Kirie has a much easier time with children than her peers and adults. This is why she befriends "Komaru" when she first meets her.
  • Fun Size: When at home, Umaru takes the form of a chibi with a hamster hood.
  • Funny Afro: Taihei's friend Bomber has a spiky Spike Spiegel-style afro.
  • The Gadfly: Umaru loves messing with Taihei. Including damaging his reputation in her school by attributing her selfish actions to him.
  • Gag Boobs: 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, much to her discomfort.
  • Girlish Pigtails: Ebina.
  • Girls Are Really Scared of Horror Movies: Umaru starts getting freaked out in Chapter 26/Episode 3C after a storm causes a power blackout, and she starts thinking about the ghosts from the horror movie she just watched earlier with her brother.
  • Gratuitous English: Episode 4 uses quite a bit when calling out the players in the competition by the initials they often use in the games, such as Umaru being "U.M.R.".
  • Growling Gut: Ebina's stomach does this in episode 11 after she brings some rice sent by her parents to Taihei and Umaru.
  • Hair Decorations:
    • Sylphin wears a hairband.
    • Ebina's prawn-like scrunchies. "Ebi" means prawn or shrimp.
    • Hikari has diamond-shaped hair decorations (as in the gemstone, not the shape).
  • Harsh Word Impact: After Taihei throws out a figurine box that Umaru nonchalantly claims she didn't need, she is surprised that she told him to. But she decides to guilt trip him anyway, and turns on the waterworks. Several of her insults hit him rather hard, with arrows piercing him each time.
  • Heel Realization: Downplayed, but in Chapter 92, Umaru realizes that she's spoiled and Taihei's nice.
  • Hidden Depths:
    • Kirie is actually very good at sports and despite being good enough at swimming to get third place in a national tournament she has no plans to go pro, instead wanting to write and draw children's picture books.
    • While Ebina is always blushing, she is actually more active in getting friends than Umaru.
    • Despite the attention-craving and obsessive "competing" with Umaru, Sylphin is actually quite a nice person who has no problems becoming friends with Umaru (and her gaming alter-ego) & co.
  • High-Pressure Emotion:
    • Ebina does this from time to time, especially around Taihei.
    • Sylphin does this after she spots her brother watching her play in the video game tournament.
  • Hikikomori: Unless forced to, Umaru would never leave her house.
  • Hoist by His Own Petard: In one scene during episode 2, Umaru attempts to force her brother awake by sleeping next to him and making him uncomfortable so she could play games with him until the morning anime started. Unfortunately she had been up all night, so she actually falls asleep, and doesn't wake up until evening. As a result, she misses both the morning and the afternoon anime shows. (Much the same happens in chapter 3, which the scene was based on, although Umaru only misses the morning anime.)
  • House Husband: Taihei looks after the flat.
  • Idiosyncratic Episode Naming: Most chapter titles are in the format "Umaru and [X]", although Ebina, Taihei and Kirie have all substituted for Umaru.
  • Imaginary Love Triangle: Ebina doesn't know Kirie considers her a rival for Umaru's affections. Vice versa, Ebina considers Kirie to be a rival for Taihei. Though they later realize the mistake with Kirie even being a Shipper on Deck for Ebina
  • Imagine Spot: Umaru has one in chapter 24/episode 7 while eating at the ramen restaurant. She goes into Super-Deformed mode, and claims that cola would go great with the ramen she was eating. It then turns out to be her imagining all this, while she eats the ramen normally.
  • Implausible Hair Color: Hikari has white hair despite being a high-schooler.
  • In-Series Nickname: Umaru has a few: Kirie calls her (or rather, "Komaru") "Master", Alex calls her "Sempai", and Bomber calls her "Tanukichi" due to mistaking her hamster hood for a Tanuki. And of course she has U.M.R., her "gamer name".
  • In the Hood: Umaru almost always wears a hamster hood when at home.
  • Inelegant Blubbering: Umaru is prone to crying and throwing a hissy fit like a little child every time she doesn't get her way, provided no one else she knows is around.
  • Informed Attractiveness: Umaru is always described as incredibly beautiful by others.
  • It's All About Me: Umaru is this, being extremely lazy with housework, and wanting to do nothing more than watch anime, eat junk food, and play games all day. She will also often complain until Taihei gives in to her demands, such as having him buy her the latest game.
  • Jerk with a Heart of Gold: Umaru is manipulative, lazy and annoying. But she cares for her friends and truly cares for her brother.
  • Last Name Basis: Ebina's first name, Nana, was initially only mentioned in a bonus chapter and a splash page. Even Umaru, her best friend, refers to her as Ebina-chan.
  • Lazy Bum: Umaru basically refuses to help around the apartment.
  • Living a Double Life: Umaru in public is the perfect student, and Umaru in private is a lazy otaku.
  • Lonely Rich Kid:
    • Ebina casually says things once in a while that give this impression. When Taihei visits her flat, he notices she has a fancy kitchen with two refrigerators, further adding to this.
    • Sylphin is revealed to be rich but seems to have no other friends beside U.M.R.(Umaru).
  • Loophole Abuse: In episode 8, shortly after the new year begins, Taihei brings up a promise Umaru made back in late November about giving it her all and cleaning up next year. He then immediately calls her on it, and she attempts to use this trope by saying that she never specified a date or time when she would do those things. He doesn't buy it however.
  • Loves My Alter Ego: Umaru has this issue with her friends. Ebina, Kirie and Sylphin, as far as they know, are friends with outside Umaru, Komaru and U.M.R., respectively. They have either not seen Umaru's real self (Ebina) or don't realize the person they know and Umaru are the same person (Kirie and Sylphin). Later Kirie and Sylphin become friends with outside Umaru but still don't know that Komaru and U.M.R. are the same person as Umaru.
  • Luminescent Blush: Seems to be Ebina's default facial expression, to the point that you can't tell if she's really nervous till steam starts coming out her head.
  • Married to the Job:
    • Taihei. He works overtime all the time and has little to no hobbies outside of cleaning after Umaru. On his one day off, he started zoning out because he had nothing to do.
    • Also applies to Kanau. Perhaps more so than Taihei, since she's the daughter of the company president. She even has a bedroom in the building she works in.
  • Meaningful Background Event: Throughout the first two episodes of the anime, Kirie can be seen in the background of several school shots, silently glaring at Umaru. In Episode 3, after Umaru finally notices her doing it, Ebina points out she's been doing it all the time and there's a brief montage of several such shots, with the glaring Kirie highlighted.
  • Meaningful Name: "Doma" can mean "in the ground." So, Umaru's name means "buried in the ground," "Komaru" means "trapped in the ground," and Taihei, "rest in peace."
  • Mundane Made Awesome: Sylphin appears with some flowers as a backdrop during episode 4. The camera then switches angles to reveal that it wasn't due to Bishie Sparkle; rather, she somehow managed to bring a flowery background onto the tennis court. She later crashed into it a few times while playing tennis against Umaru.
  • NEET: Umaru's future plan after she graduates is to continue to live off her brother.
  • Nice Job Breaking It, Hero: Umaru accidentally spills soda on the cable modem under her brother's desk in episode 10. She then tries desperately to connect various devices online, only to find out none of them will connect, and suffers a brief Heroic B.S.O.D. due to not being able to connect to the net.
  • No Sense of Personal Space:
    • Umaru does this from time to time on Taihei, including clinging onto him while in Super-Deformed mode.
    • Kanau likes to get really close to Taihei as well at work, close enough that she's within kissing range of his lips. Since he's Oblivious to Love, as well as being her subordinate, this makes him uncomfortable, as well as missing the point that she likes him.
  • Oblivious to Love: Taihei doesn't notice Ebina's or Kanau's feelings for him and Umaru seems to have no idea that Kirie wants to be more than friends.
  • Odd Friendship:
    • Kirie became friends with both forms of Umaru, and both friendships are odd, in different ways.
    • Sylphin, meanwhile, wants to beat Umaru with her new friend U.M.R's help.
    • Inside Umaru also gets along quite well with Bomber because both of them are easygoing people by nature.
  • Oh Crap!: In Episode 2, Umaru can only react with horror when she realizes that Ebina may have seen her turn into her inside self and throw a tantrum at Taihei on their visit to a restaurant.
  • Once a Season: Starting with chapter 10, the opening panel of every tenth chapter is by another light novel/manga artist. (The pattern's broken with chapter 99, which gets a contest winner's opening panel instead of chapter 100).
  • One Degree of Separation: Bomber and Alex are introduced as Taihei's co-workers, with Bomber as an old school buddy. They are later revealed to also be the older brothers of Umaru's friends Kirie and Sylphin respectively. Later it's implied that Taihei meets Ebina's missing big brother on a business trip. It also turns out that Bomber knows Sylphin through Alex.
  • Only Friend: For a while Ebina seemed to be Umaru's only friend. This was averted when she became friends with Kirie and Sylphin.
  • Orgasmically Delicious: Umaru seems to have something of an orgasm when drinking cola.
  • Otaku:
    • Umaru. She is totally obsessed with Anime and gaming merchandise, and hoards a pile of them at home.
    • So is Alex. He and Umaru become good friends due to their love of anime.
  • Pet the Dog: For all the abuse she heaps on Taihei, Umaru is given a lot of moments where she does genuinely end up appreciating all the things he does for her. Especially if it's pointed out by another character, such as Ebina commenting that chopping up green peppers takes a long time to prepare when Umaru finds some in her lunch.
  • Primal Fear: As noted in the Sick Episode entry, instead of playing a prank on Taihei, Umaru has a very concerned look on her face when her brother is lying on the floor with a high fever, fearing he could die from it. She then attempts to do what she can to help him get better.
  • Promotion to Parent: With their parents absent, Taihei's taken the parental role.
  • Pun-Based Title: "Himouto" is a portmanteau of "Himono"note  and "imouto" (little sister).
  • Real Place Background: The series is set in Hachioji, Tokyo.
  • Red Baron: The Demon Taihei, due to the fact he always got a perfect score on his tests.
  • Relative Error: People often get jealous of Taihei after assuming Umaru is his girlfriend.
  • The Rival: The series later introduces Hikari, Kanau's little sister, as one for Umaru over Taihei.
  • Serious Business: Umaru towards snacking, as one can see in episode 1.
  • Shipper on Deck: After figuring out that Ebina likes Taihei and after receiving some unwitting advice from Umaru, Kirie decides to support Ebina's feelings and even tells the latter of her intent.
  • Shout-Out: Oh so very many. The manga features more that had to be cut out of the anime version.
    • The anime's opening contains parodies of Pokémon, Mario Kart, and Monster Hunter; the song itself actually contains the infamous death noise from Super Mario Bros. 1.
    • Umaru is a fan of Jun Piece, which she reads in Junpu; her favorite character is "that cute reindeer".
    • Her and Sylphin's favorite fighting game is Space Stream Fighter IV; Sylphin's character of choice looks a lot like Fi. The game also has a character who's just plain Guile, no changes or attempts to hide his identity.
      • Speaking of, one of the employees at the Gapcom game center has a white headband, fingerless red gloves, and Big Ol' Eyebrows, making him look just like Ryu.
    • In the manga version of the Stream Fighter tournament, the other contestants include Satoshi, Bayonetta, Shinya Arino, and Segata Sanshiro.
      • In one of Sylphin's flashbacks, we see that what got her into fighting games was watching a tournament which was won by U.M.H. — in other words, legendary Street Fighter champ Daigo Umehara.
    • In the Umaru-chanS shorts, the Imouto Sentai Umaranger costumes are heavily based off of Mahou Sentai Magiranger.
  • Shrinking Violet:
    • Ebina and Kirie. Ebina, though, is mostly normal until Taihei is around.
    • Umaru comes to the conclusion that this may apply to herself when she realizes that all of her friends approached her first.
  • Sick Episode: Umaru catches a cold in chapter 22/episode 10, due to sleeping on the floor with the A/C on. The very next day, Taihei catches her cold, and Umaru initially plans to cook some hot and spicy foods as payback for him not staying home to take care of her the previous day. But when she arrives home and sees that his fever went up, she forgets about her revenge and instead tries to help him get better instead.
  • Similar Squad: Ebina's friends from Akita are very similar, personality-wise, to Ebina, Kirie and Umaru.
  • Single-Target Sexuality: Kanau is mentioned by other men as being very beautiful, but she's only interested in Taihei.
  • Sitcom Arch-Nemesis: Averted; while their classmates think there is animosity between Umaru and Sylphin, both are quick to deny there are any such feelings.
  • Situational Sociability: In public, Umaru is The Ace, a straight-A student and stellar athlete. At home, Umaru is a lazy, spoiled brat who would rather sit around playing video games or reading manga than do anything productive. The difference is so stark that there are instances of her being mistaken for two different people.
  • Slice of Life: The series focuses on Umaru and her daily life at school and home, with the occasional spotlight on the other characters such as her brother Taihei.
  • The Smart Guy: Taihei always got 100s on his exams.
  • Smug Smiler: A lot of Umaru's smiles are these when she's at home.
  • Spirited Competitor: Sylphin loves competing against people and will enter any competition or game just to prove her skill, though she dislikes gambling games that rely on luck. She has singled out Umaru as her ultimate rival, but holds no actual hostility toward her, in fact it's a strange attempt at becoming friends. It turns out that she gets it from her mother, who's not satisfied unless she wins first place.
  • Spoiled Brat: Umaru when she's at home and/or wants something, such as the latest game. She'll throw a tantrum until Taihei gives in and gets her whatever she wants.
  • The Stinger:
    • After the end credits in episode 3, we jump into something that looks straight out of a horror movie - because that's exactly what it is, a horror movie Umaru and Taihei are watching.
    • In episode 8, Kanau shows up behind Bomber and Taihei as the two are stuck at work on Christmas Eve. After the credits roll, we are then shown the events from her point of view, including Taihei inviting her to hang out with him and Bomber like they used to. She politely declines, but the look on her face shows she really wanted to. He also later sends her a picture of him and Bomber in santa suits. She promptly crops the picture to show only him, then sets it as her phone's wallpaper.
  • Strong Family Resemblance: The few glimpses we get of Mrs. Doma (usually thanks to Taihei's memories) show that she looked and sounded like an adult version of Umaru.
  • Super-Deformed:
    • The moment Umaru walks through her front door she becomes a chibi with a Cat Smile. In a hundred chapters and a couple thousand panels Umaru has only appeared non-deformed while indoors twice, and one of those was a chapter opening. This isn't merely an Art Shift but an actual physical change that can even fool Umaru's friends and which is referenced a few times in the manga.
    • In the anime, Umaru switches between the two forms quite a lot.
  • Supreme Chef: Taihei is quite the good cook, and ends up making food for himself and Umaru. However, both of them lie to friends and coworkers when they claim it's Umaru who makes them. For Taihei, Bomber, and to a lesser extent, Kanau, don't believe he could cook food that good himself. Umaru meanwhile doesn't want to ruin her perfect student persona at school when she claims she makes the food.
  • Sure, Let's Go with That: When Kirie suggests inside Umaru is Umaru's younger sister, Umaru runs with it and introduces herself as "Komaru."
  • Teen Genius: Umaru, who aces in any tests and learns everything easily. Taihei as well when he was at school.
  • 10-Minute Retirement: At one point Umaru realizes she has been quite active with her friends and decides that she will give up the Himouto lifestyle. She even decides that she will tell her friends about her double life, but when the time comes she is so visibly afraid that her friends will abandon her that Kirie says they don't need to know and that they love Umaru unconditionally.
  • Third-Person Person: Umaru, when not in public.
  • Tohoku Regional Accent: Ebina occasionally slips into this, having originally come from Akita.
  • Took a Level in Kindness: While Umaru is still a Lazy Bum, the later chapters seem to tone down her jerkass tendencies compared to early ones. Most obvious in chapter 60, when Umaru picks a snack specifically for Taihei following his giving a presentation. The Jerkassery is still present, as she got the snack assuming he'd fail and would need a pick-me-up and was genuinely shocked when things went well. But the fact remains she got a present for her brother thinking he'd need it.
  • Trademark Favorite Food: No matter what she's eating, from junk food to ramen to steak, Umaru has to have her cola.
  • True Companions: How Taihei describes his relationships with Boomer and Kanau.
  • Two Guys and a Girl: Taihei, Boomer and Kanau in high school always hung out together.
  • Unknown Rival: Sylphin considers herself Umaru's rival. Umaru doesn't seem all that interested. Though once they become friends, she drops this.
  • Unsound Effect: "Umaru~un", the sound effect of Umaru's amazingness, which happens whenever she shows up in her outside form.
