A high school girl who unfortunately scares others thanks to the sadistic look she puts on when she smiles. Luckily for her, her looks manage to land her a job at the cafe as the sadistic waitress.
- Cherry Blossom Girl: Comes from a traditional Japanese family, has Yamato Nadeshiko elements to her appearance and personality, her waitress outfit is pink and is introduced standing close to cherry tree. Her family name literally means "cherry blossom palace".
- Cordon Bleugh Chef: She accidentally makes a parfait with salt, vinegar, and Tabasco because she wasn't careful enough to read the tags. The customers love it anyway.
- Cute Clumsy Girl: Maika has a combination of not being terribly adroit as well as being a bit sheltered, which results in her making mistakes like throwing coffee on customers (after a trip) or making an utterly disgusting parfait (due to not reading the ingredients). A combination of her shyness and her severe looks results in her inadvertently nailing the "sadist" role she was hired for.
- Face of a Thug: Her default expression gives her an unfriendly appearance, which makes searching for a service job difficult for her. This is largely an Informed Deformity, since even when she looks her scariest she's just as cute as everyone else.
- Feminine Women Can Cook: Despite her initial screw up with the accidental "sadist parfait", Maika soon learns to cook very well and prepares desserts or bento for Dino often.
- Foreign Culture Fetish: Despite her family being extremely traditionally Japanese (or maybe even because of it), she has a preference towards the European. The main reason she looks for a job in the first place is so she can study abroad.
- Friendless Background: She never tells her coworkers about this, but the fact is that her siblings are surprised that she has friends from Cafe Stile that would come visit her when she has a cold. Makes sense because of Maika's sheltered, traditional upbringing and her accidental glares often scaring people off.
- Girlish Pigtails: She keeps her hair tied in low twin-tails because her hair is extremely vulnerable to frizzing. Keeping it tied down keeps it controlled and presentable.
- Hair of Gold, Heart of Gold: One manifestation of her Foreign Culture Fetish was a desire to dye her hair blonde. She had an imagine spot full of sweetness and light, indicating this trope. Her parents, however, were mortified that she was becoming a culture rebel/delinquent thug.
- He Is Not My Boyfriend: She denies Dino is her boyfriend when her classmate assumes that's the case after hearing Maika took Dino with her to buy a swimsuit, which is you know, boyfriend stuff.
- I Am Not Pretty: She thinks of her own face as unattractive and scary-looking because of her Tsurime Eyes. To her disbelief, Dino tells her he likes her eyes and Stile's customers find her cute even when she glares at them because it suits her sadist character.
- I Didn't Mean to Turn You On: She gives Dino a nosebleed nearly every time they interact, usually by unintentionally enticing the masochist in him.
- Informed Deformity: She's treated like she has a Face of a Thug, but her design is very cute — and this is a Moe show, where everyone is cute. The story tries to justify it with her Tsurime Eyes, not that that really makes a difference.
- The Ingenue: She's a bit sheltered and shy, frequently missing some of the implications of some of the things that the other characters say (when Akizuki went on about yuri, Maika thought he meant the lilies that the genre is named after). That said, despite her role at the restaurant, she's almost comically kind and gentle to everyone she meets, to the point that Mafuyu warns her repeatedly that she's going to be taken advantage of due to her unfailing kindness.
- Keigo: Always speaks in formal linguistics, highlighting her upbringing from a traditional Japanese family. Akizuki notes Maika retains this trait even as she spends a scene acting like a full on dominatrix.
- Love You and Everybody: She openly says she loves Dino, along with all of Cafe Stile's staff.
- Mean Character, Nice Actor: In her job as a waitress, she acts like a sadist due to her appearance, but she is actually a Nice Girl at heart.
- Nice Girl: Very, very, very much so. She's so nice that Mafuyu worries about her a lot since she believes Maika could be taken advantage of in the future if she continues being too nice for her own good. That said, if her siblings do anything to bother visitors, she gets angry.
- No Social Skills: Having been raised in a very traditional household, Maika often struggles to know how to act in certain situations because of her utter lack of social experience.
- Oblivious to Love: Dino has an extremely open crush on her from the moment he meets her, to the point where his first words to her were saying "I love you" as his nose bled. Despite this being clear as crystal to everyone else, she is completely oblivious to the fact, with it being implied that this is mostly due to her upbringing in a very traditional family giving her a pretty sheltered mind. This also includes her being oblivious to the fact that Dino very obviously likes it whenever she ends up abusing him both verbally and physically.
- Ojou: There are hints that indicate Maika's family is very wealthy. Her excessively polite behavior and speech, as well as the Big Fancy House are the most obvious signs. Funding her study-abroad plans with a part-time job is entirely by choice is a less obvious one.
- Pink Means Feminine: All her main attires are pink, such as her school and work uniforms, and she's the most traditionally feminine girl in the main cast.
- Pop-Cultural Osmosis Failure: Frequently has cases of the Unknown Reference subtype due to her traditional upbringing. For example, when Akizuki admitted he likes yuri, she doesn't know what it is. Akizuki finds explaining all the Anime Fan Speak to Maika worse than openly saying he's an otaku.
- Prone to Tears: She easily cries when feeling sad or anxious, usually resulting in Dino being accused of having done something bad to her.
- Purely Aesthetic Glasses: She has good eyesight, but she'll try to hide her Tsurime Eyes with glasses to look less intimidating.
- Rapunzel Hair: Her hair reaches down to her hips when tied in twin-tails, and this length underscores her Yamato Nadeshiko trait, because her beautiful black hair is on display. Dino certainly likes it.
- Sadist: Subverted. She plays this archetype in Cafe Stile, by insulting customers, glaring at them with her Tsurime Eyes, and urging them to eat disgusting foods. The last part is accidental because Mean Character, Nice Actor applies to her.
- Temporal Theme Naming: More subtle than the other characters, but Sakura is part of her family name- cherry blossoms are the ultimate symbol of spring in Japanese culture.
- Trauma Button: When her hair is undone in preparation for ponytail day, it flies out wildly because Maika has long had problems with static electricity messing with her hair if it wasn't tied down. While in this state, Maika huddles down on the floor and begins chanting names like "Medusa", implying they were used on her and making the others worry they've inadvertently awakened some past trauma.
- Tsurime Eyes: Only person in the cast to have sharp eyes, and obviously they are part of her Face of a Thug look.
- The Un-Smile: She has this as a recurring issue. She's a very kind and pleasant person, but when she gets nervous or anxious she gets a scary look in her eyes and her smiles become terrifying. This tanked numerous job interviews she had until she came across Cafe Stile, which hired her because of this trait.
- Yamato Nadeshiko: Has hints of this based on her appearance, traditional family's background, mannerisms, and her soft and gentle way of speaking in addition to her nice girl traits, though her scary, sadistic-looking face puts a small damper on that one. Interestingly, Maika lacks the complete conservative adherence to Japanese culture that her family has, since, while she still dutifully follows old traditions out of respect and obedience for her family, she is, in her own words, sick of Japanese-related things thanks to her household. This has been the case since the age of five.
The cafe's tsundere waitress. Kaho works at the cafe to support her expensive gaming hobby.
- Book Dumb: As a side effect of a very generalized video game addict. For one segment, she has to have Mafuyu tutor her when she fails a math test at school and is forced to do a makeup exam.
- Buxom Is Better: She draws a crowd whenever she plays games that involve a lot of movement; not because she's good at it, but because of her freely moving gratuitous assets.
- Closet Otaku: Hides her hobbies to her classmates. Volume 3 has a chapter about the whole restaurant trying to hide her from two of her classmates who happened to visit Stile.
- Covert Pervert:
- Kaho becomes particularly curious over the dirty doujinshi that gets left at Cafe Stile. She tries to sneak a peek at it while alone, only to get caught in the act by Mafuyu, as the said doujinshi already caused a Harmful to Minors moment to Maika.
- Zig-zagged on her covertness twice in episode 6.
- When Dino asks her and the other girls by text to show him their swimsuits as a reference for finding Maika's. Whereas all three of them accuse him of sexually harassing them, Kaho also responds with the emoticon of nosebleed.
- Later on, when she realizes Akizuki hasn't seen a girl with a chest the size of hers in a swimsuit before, she teases him with them for the rest of the episode. Needless to say, she may not be as covert as many have thought.
- Exhausted Eye Bags: Has these in episode 10 as a side effect of being sleep deprived from studying.
- Friendless Background: Before joining Cafe Stile, the only friends she had were those she found in the internet. She had no idea how to talk to Akizuki back then.
- Gamer Chick: Highly proficient in gaming, both in console and in arcade games. Hearing her customers talk about them causes her to lose focus. Tends to get along with and even get a little playful with the Otaku Akizuki as a result. When her mother threatens to ground her from her video games after failing her math test in episode 10, her response was not to study harder for her makeup test, but to play as much as possible before she fails again and gets grounded.
- Girlish Pigtails: Invoked. She puts her hair up in pigtails under Dino's recommendation, as part of her Tsundere act.
- Mean Character, Nice Actor: Like Maika, though in a different way: she plays a grumpy tsundere character, but outside work she's very laidback and friendly.
- Ms. Fanservice: Being the cast member with the largest bust by a large margin, episode 6 contains the expected Male Gaze directed at her. She even seems to try to flaunt it with a flustered Akizuki.Kaho: "Jeez! I'm sure you got an eyeful at the school's pool!"Akizuki: "That's not the same thing! Get away from me!"
- Nice Girl: In contrast with her tsundere act as a waitress, she's actually a very kind, friendly and cheerful girl.
- Rapunzel Hair: Her twintails go all the way down to her knees for maximum twin tail effect.
- Ship Tease: Done from time to time with Akizuki. She tends to get flustered too when he ends up seemingly more interested in other stuff, like when he accidentally grabs her breast, then immediately seems more comfortable grabbing the manager's instead.
- Skewed Priorities: While her mother blasts at her for performing poorly at an exam and threatens to ban her from gaming if she doesn't score at least an average mark in the make-up test, she nevertheless makes the most of what little gaming time she has remaining.
- Tareme Eyes: Even though she plays as a tsundere character, her eyes represent her friendliness outside of work.
- Temporal Theme Naming: Her given name contains the 夏 kanji (also pronounced as "natsu"), which is Japanese for summer.
- Tsundere: She plays this archetype in Cafe Stile, specifically the harsh type by grumpily saying things like "I wasn't waiting for you or anything, but as long as you're here, you might as well sit down". On one occasion, she helps a customer with a technical problem on their handheld game and said she only added herself to his friends list as a test and so he should "be grateful". She also pulls it off out-of-character when Akizuki compliments her in episode 10, though otherwise she's not like this at all outside of work.
- Two First Names: Hinata is both a unisex Japanese given name and surname.
A college student who works as the little sister waitress because of her short stature and youthful looks.
- A-Cup Angst: She's quite jealous since Kaho, who is younger than her, is so much more well-endowed.
- Big Sister Instinct: Off the clock, Mafuyu comes off as a bit protective of her juniors at the cafe. Which isn't to say she won't indulge in a little playful tormenting of them (particularly Maika), but she does overall look out for them. Justified as she's an actual older sister, having three young brothers.
- Brutal Honesty: She's not the type to mince words. For instance, she lays into Kaho pretty hard upon learning she was slacking off after failing a test.
- Celibate Hero: In the manga, one of her past relationships ended abruptly because her boyfriend was arrested out of being Mistaken for Paedophile. This somehow caused her to think she should never have any romance. In the anime, she simply thinks she has no time for dating, especially when she would rather watch anime.
- Contralto of Danger: She speaks in a cute, babylike voice when playing her little sister role. Her normal self has a deep, dry voice that shows her sardonic personality.
- Cool Big Sis: She can play the role of a mature older sister to her younger co-workers, mainly Kaho who comes to look up to her after getting her help to improve her grades at school.
- Cosplay Otaku Girl: Mafuyu doesn't wear the outfits she collects, but she does get a sense of satisfaction from acquiring them to begin with, and is absolutely thrilled whenever she finds someone else to model the costumes for her.
- Double Standard: Abuse, Female on Male: Downplayed. She mostly abuses Dino, usually by hitting him if she thinks he's acting or doing something perverted. Although a lot of her abuse is directed towards Dino, she has no problems hitting other women like Kaho or Maika either.
- The Fake Cutie: She plays the part of a cheerful and adorable little sister for her job as a waitress, but her real personality is more of a Deadpan Snarker who won't hesitate to insult or hit someone when they're being stupid. She's also a 20-year-old college student despite her short height and youthful looks.
- Little Miss Snarker: If a dry and caustic remark has to be made, Mafuyu is most likely going to have that honor. She also fits the trope with her youthful appearance, though she's Older Than She Looks.
- Little Sister Heroine: Mafuyu plays this archetype in Cafe Stile, where she acts like a cute and cheerful little girl who addresses customers as "onii-chan".
- The Napoleon: Very short and childlike, also prone to losing her temper and getting violent around Dino.
- Nice Character, Mean Actor: Downplayed; she plays the part of a cute, cheerful Little Sister Heroine when working at Stile, but she's actually more of a Little Miss Snarker who can be brutally honest and won't hesitate to hit people when they're being stupid. That said, she's not a bad person and just isn't as cheery as she pretends to be for her job.
- Older Than She Looks: She's twenty, but she still looks young and short enough to play the Little Sister Heroine role in Cafe Stile.
- Otaku: She's a big fan of Magical Girl works. She found Dino's sexualization of the cast disgusting, preferring a pure outlook and watching the shows for the plot, which just made her look childlike to others.
- Sensei-chan: She tells Kaho that she wants to become an elementary or nursery school teacher. Given the way Mafuyu looks, Kaho can picture her as an adorable teacher because she would look only a little older than her kid students.
- Stern Teacher: In episode 10 of the anime, she hits Kaho for playing video games while she's doing poorly in school, and later gives her 'hard education' after discovering that her tablet is only used for gaming. Kaho learns from experience that having Mafuyu as a tutor can be rough, but the results of her teaching are worth it.
- Tareme Eyes: When she acts out her little sister role, her eyes become noticeably more droopy to fit her childish and innocent role better.
- Temporal Theme Naming: Winter (Mafuyu).
- Token Mini-Moe: The other archetype Mafuyu plays in Cafe Stile. In reality, while she's the youngest-looking member of the cast, she's actually a 20-year-old college student.
A doujinshi author that works at Cafe Stile to get ideas for her work.
- Adaptational Curves: Noticeably bustier and taller in the anime. Canonically, she has a small chest and is shorter than Kaho; in the anime, Miu is much taller than her.
- Buxom Is Better: Dino reads a customer's feedback about Miu's Cool Big Sis character "lacking something", she immediately assumes he's talking about her breasts. Rather than getting upset, though, she agrees and reasons that, indeed "An oneesan should have big boobs!".
- Cloudcuckoolander: Her thought processes can be quite a maze, especially when she brainstorms for new ideas for her works out loud. Sometimes she mixes reality with fiction, creating outlandish scenarios in her head about the people around her.
- Contralto of Danger: Largely Played for Laughs. Miu already has the deepest and most mature voice out of all the female characters, but her voice gets even deeper when her imagination gets really wild and somewhat unsettling.
- Cool Big Sis: Her role in Cafe Stile is to be a mature and flirty elder sister.
- A Day in the Limelight: For being a part-timer in cafe Stile, this is expected. There are 2 instances:
- Episode 4, mainly the first half of the episode, introduces Miu.
- Episode 8's final segment focuses on both Miu and Hideri, almost not having any of the main characters.
- Everyone Has Standards: Miu may have very perverted thoughts, but even she will stop a friend from committing a heinous act, intentional or not.Miu: Please don't aim for early retirement due to a scandal. note
- The Gadfly: She takes delight in trolling Hideri while they shop for outfits.
- Girlish Pigtails: She ties her hair into twin braids, shorter than Kaho and Maika's. It's part of her role, since she wears a ponytail during her work as a mangaka.
- The Glasses Gotta Go: While she usually wears glasses, she opts to wear contacts instead at work to play her enticing Cool Big Sis role better.
- Innocently Insensitive: While her interests make her quite eccentric, she's usually shown to be polite and helpful. That being said, some of her thoughts and actions can be rather unnerving- the problem is, she doesn't seem to realize how weird she can be.
- Lovable Sex Maniac: Not only does her big sister act at the cafe have some overt sexual tones to it, she also makes sexual references outside of work occasionally. It's all Played for Laughs.
- Meganekko: She normally wears glasses and is an cute girl who happens to be a doujinshi artist.
- Opposites Theme Naming: avoids the Temporal Theme Naming of most other characters and is instead paired with Hideri: Miu is written as "light rain" (美雨), in contrast to Hideri which is written as "drought" (ひでり).
- On the other hand, both names may also qualify as Temporal Theme Naming as both names reflect the 2 tropical seasons, with wet and dry for Miu and Hideri respectively.
- Pen Name: She writes her doujinshi under the name "Hanazono Folder".
- Reclusive Artist: Miu seems to heavily dislike staying outside and interacting with people:
- In Episode 6, the cast goes on an outdoors trip on a lake. Kaho and Akizuki and especially Miu appear almost physically ill.
- In Episode 8, she happily thinks to herself that, having bought enough paper, she won't have to go outside until the next Fan Convention.
- Running Gag: In the anime, Miu softly punching Hideri's stomach is this. She punches him only at the clothing store in the manga.
- Sequential Artist: A rather famous doujinshi artist. When she starts working at Cafe Stile, she asks for many free days to meet her deadlines and attend Fan Conventions where she can sell her works.
- Shipper with an Agenda: She ships Dino X Maika, thinking it's moe, but she doesn't want them to become a couple yet because their interactions give her a lot of material to work into her manga.
- Shipping Goggles: She writes hentai doujinshi for any type of pairings, indicating she wears all three types listed in the TropeCo catalog.
- Ship Tease: With Hideri... sort of, maybe. Miyuki Nakayama draws them together quite often, and their names and their birthdays are curiously linked together like Dino's and Maika's, implying they may eventually become a Beta Couple. For the time being, however, it's Miu who is interested in Hideri with him being rather confused and oblivious about it, and it's ambiguous whether she's just messing around with him or if she holds some genuine affection. In a later manga chapter, she is rather impressed hearing about Hideri's Bully Hunter backstory, praising Hideri for what she calls his "chivalry" (漢気) and declaring she's now a huge fan of his.
- Stronger Than They Look: She's carrying two bags containing reams of paper. When Hideri tries to help her with it, he initially struggles to lift it, showing that the bags are a lot heavier than they appear.
- Tareme Eyes: Her eyes are noticeably droopy, much like Kaho Hinata. It contributes to her "motherly big sister" character and makes her real personality pop out more.
- Write Who You Know: In-Universe. Miu started working at Cafe Stile because she needed inspiration for her manga artist job. She comes up with her first original manga where the main characters are a sadistic maid and a masochist butler, both of whom are explicitly based on Maika and Dino.
Cafe Stile's fifth addition, Hideri dreams of being an idol someday. The staff is enamored with Hideri's adorable looks, but Hideri may hide a few surprises.
- Actor Allusion: Hideri performs the Nico Nico Nii which is fitting given he shares the same voice actress with the one who started that in the first place.
- Attention Whore: A lot of his actions are intended to attract attention from others; for example the reason he applies to Stile is on the line of "attracting fans."
- Attractive Bent-Gender: He's a Wholesome Crossdresser who can pass off as a very convincing girl.
- Bokukko: Subverted. The other characters are very surprised when they hear the male pronoun boku coming out of such a cute girl's mouth. Turns out said 'girl' is actually a crossdressing boy.
- Bully Hunter: The manga reveals he used to run an idol online community but got in trouble for flaming against trolls in a live chat instead of just reporting them. What made him so furious is that he finds those who harass and attack people for their passions "unforgiveable".
- Cat Smile: Hideri's default expression.
- Catapult Nightmare: The Stinger at the end of Hideri's introduction in episode 8 has the characters cosplaying preschoolers, with Miu dressed as a teacher. Hideri then shows up wearing that same smock the girls are wearing. He then wakes up, having fallen off his bed, clearly traumatized by Miu and Mafuyu dressing him up in one the previous day.
- Character Exaggeration: His use of his smartphone and his Attention Whore tendencies are amped up in the anime. The anime cuts a number of lines from the manga where Hideri behaved in a more intense masculine manner; most notably, his introduction chapter ended with him declaring himself as Dino's rival and switching from his usual ''boku'' to ''ore''- a scene the anime completely skipped. On the other hand, the anime added a lot of original scenes of Hideri using his smartphone and taking selfies, painting him as a vapid Phoneaholic Teenager and Selfie Fiend; whereas in the manga he's shown using his phone once. As a result, anime Hideri comes across as noticeably more annoying and superficial than his manga counterpart.
- Characterization Marches On: In his early manga appearances and most of his anime run, Hideri is a shallow brat who only wants to brag about how cute he is. Come the manga chapters beyond the anime adaptation, however, and he slowly turns into a more serious-minded and deadpan person who shows some kinder traits. It's hard to tell if it's the mangaka changing her mind about the character or if it's deliberate Character Development.
- Country Mouse: Hideri comes from a family of farmers but hates working there and would rather stay in the city to wear fashionable clothes and be a glamorous idol. His country origins pop out once in a while however, especially in his speech style.
- A Day in the Limelight: Episode 8 almost entirely focuses on Hideri. As part of his attention-seeking personality, this is expected. Taken even further that the final segment of this episode was almost entirely Hideri and Miu, in which the latter wasn't added until the end of Episode 3.
- Dragged into Drag: He's already into crossdressing, but is mortified when Mafuyu and Miu force him to wear a Magical Girl cosplay and a female preschooler uniform for fun.
- Effeminate Voice: He's a Wholesome Crossdresser who speaks in a cutesy, high-pitched voice provided by Sora Tokui. His voice does turn deeper and masculine-sounding in moments of emotional distress.
- Expressive Accessory: His hair bow perks up or falls down depending on his mood.
- The Fashionista: His Non-Uniform Uniform happens to be a custom work. Also, half of his introduction episode is him looking for clothes that accentuate his cuteness.
- In the OP, Hideri's "S word" is Surprise! It's surprising all right...
- When Akizuki points out he's overworked in the kitchen and that Cafe Stile should hire male staff, Dino vehemently objects, claiming that he doesn't want rivals and that another guy could steal Maika away from him. Guess who willingly joins Stile the following episode/chapter?
- Gender Reveal: Indeed, Hideri is a guy. Unlike most examples, however, the other characters actually manage to figure it out before he (cheerfully) admits it.
- Hidden Depths: For someone who claims to be interested only in himself, he's surprisingly prone to helping people out without getting much in return. Later manga chapters seem to confirm this further.
- Idol Singer: Hideri's role in Cafe Stile is to act like an idol, though no singing is shown or heard.
- In Touch with His Feminine Side: He loves fashion, aspires to become an idol, and acts more cutesy than his female co-workers.
- It's All About Me: He has stated in Internal Monologue that he has never taken much attention at anyone other than himself.
- Keet: A very cutesy, talkative, and cheerful boy. Fits his feminine appearance.
- Long-Haired Pretty Boy: He has long silver hair running down his back, which combined with his cute looks make it easy for him to pass off as a girl.
- Matchmaker Crush: He starts out helping Dino win Maika's heart, but increasing hints in the manga show that Hideri himself might have fallen for Maika as well.
- Narcissist: Hideri believes himself to have been gifted cuteness from up above, and is obsessed with standing out from everyone else.
- Nice Character, Mean Actor: Not as dramatic as Mafuyu, but behind the cute Idol act Hideri is quite flippant and sharp-tongued.
- Non-Uniform Uniform: Wears a waitress uniform that's a little more frilly than the others' and also uses a hair ribbon in place of the usual headscarf.
- Opposites Theme Naming: avoids the Temporal Theme Naming of most other characters and is instead paired with Miu: Hideri is written as "drought" (ひでり), whereas Miu is written as "light rain" (美雨). Coincidentally, the two are often seen together.
- Like the rest of the waitresses and Akizuki, both his and hers may also fall under Temporal Theme Naming as Hideri seems to reflect the tropical season's dry season to Miu's wet season.
- Proud Beauty: Hideri is so cute that he can make a very pretty girl when crossdressing, he knows it, and his dream is becoming an idol so he can gather fans who worship his adorable looks.
- Shipper on Deck: Decides to help Dino out with Maika, though with little success. One of Hideri's suggestions actually makes Maika think that she was about to be fired!
- Signature Headgear: He always wears a large black ribbon that is very reminiscient of rabbit ears.
- Sitcom Arch-Nemesis: Dino initially dislikes him a lot, mainly because he hates the idea of hiring another male who could turn into a love rival. On the other hand, Hideri has a bit too much fun mocking Dino for his lack of courage towards Maika.
- Sophisticated as Hell: His speech style seems like regular Keigo at first, but it's actually filled with very informal and typically boyish language elements, especially when he loses his cool. At its peak, all polite forms disappear completely and he talks like a young male thug.
- Stronger Than They Look: Catches a falling Akizuki and later pushes Dino with enough strength to make him fall towards the wall: this despite being much, much smaller than both men. Justified as his family runs a farm, so he's used to physical labor.
- Third-Person Person: He refers to himself in third person when playing his idol role at work.
- Tiny Schoolboy: At 1.5m (5 feet), Hideri's somehow below average for a girl. However, Hideri is actually a boy, making him a lot shorter than the average male high school student.
- "Which Restroom" Dilemma: Tries to walk into the girl's bathroom, but Miu pulls him out and he mentions that his idol persona will come to an end due to public scandal. He likely would have pulled it off, though. Indeed, a couple men who were walking out of the men's room gave him very strange looks as he ran in.
- Wholesome Crossdresser: He's a cute boy who likes dressing like a girl and works as a waitress. The only one who seems bothered by this is Dino, but only because Dino hates other men being near Maika.
- Voiced by Tomoaki Maeno
The Italian manager of Cafe Stile who has an unhealthy obsession towards Maika.
- Age-Gap Romance: He's ten years older than his crush Maika, who is only 16 years old. At one point, he got arrested when he was caught fawning over her in public.
- Ambiguously Christian: Nothing firm, but he is an Italian and makes frequent references to a capital-g God and The Virgin Mary.
- Bishōnen: He's very good-looking, but this is offset by how he's also a huge Otaku who's obsessed with Maika.
- Butt-Monkey: Because he's too much of an otaku, the rest of the cast make fun of his constant lusting towards Maika, his cowardiance, wimpiness, and his general lack of work ethic. The only one who doesn't is Maika, and even she she does things like step on him or flash her sadistic stare at him.
- Crazy Jealous Guy: Doesn't take it well when he hears Maika may be dating someone. Also says he'll never let her quit, which is usually said in a cutesy manner, but can probably be mistaken for this trope as well.
- Dogged Nice Guy: Dino is very open about his big crush on Maika and always makes attempts to become closer to her, most which backfire or Maika misunderstands.
- Has a Type: Japanese girls with long, flowing black hair is what attracts him to Maika, in addition to her eyes. In his own words, "black hair is justice".
- Love at First Sight: He falls hard for Maika pretty much at first sight because she's exactly the type of woman he's into; black-haired Japanese girls. When he first talks to her, he shouts "I love you" while having a nosebleed.
- Mistaken for Pedophile: He gets himself in unfortunate situations where people will mistake him as a child molester.
- Nosebleed: A major Running Gag with him, almost always triggered by Maika flustering him. An odd case in that he claims to actually have a condition that causes nosebleeds, making it more than just an erection metaphor.
- Occidental Otaku: An Italian living in Japan that owns a Cosplay Café based on major anime archetypes and watches Otaku O'Clock anime.
- One Head Taller: His crush Maika barely reaches his shoulders, showing their significant age difference.
- Only One Name: His surname was never given.
- Phenotype Stereotype: An anime European with blonde hair and blue eyes.
- Pointy-Haired Boss: While he owns Cafe Stile, Dino is a goofy Occidental Otaku who spends most of his time gushing over one of his waitresses. His employees Mafuyu and Akizuki often beat him up whenever he acts too foolish or perverted.
- Running Gag:
- Him and the police. Although it is to be noted that this slows down as the series progresses, as after he ACTUALLY gets arrested and clears up the misunderstanding, it never really happens much.
- Mafuyu or Akizuki beating him up, for similar reasons.
- Satellite Love Interest: Dino basically can be summed up by his big crush on Maika. He's actually her and the rest of the main cast's boss, but he's hardly ever seen doing anything other than being attracted to her or trying to impress her. Other than his crush on Maika, his only defining character trait is that he loves Japanese pop culture and black-haired girls, both which are the main reasons why he likes Maika so much.
- Single-Target Sexuality: His actions pretty much show that he's only interested in Maika, though he does a terrible job at showing his romantic interest in her, such as when she thinks she's not doing her persona correctly at work due to stuff he says about it.
- Sleepyhead: He falls asleep at work all the time because he stays up late watching anime.
- Tareme Eyes: His eyes are droopy, as opposed to Maika's sharp eyes. Maika even thinks that she should switch her eyes with his so the other people won't be afraid of her anymore.
- Through His Stomach: He very much enjoys eating the desserts Maika bakes for him, although it comes at the expense of him getting fat. He's also thrilled when Maika prepares bento for their "date" when taking their dog, Owner, to the park.
- Too Kinky to Torture: He's turned on by Maika's (unintentional) abuse. Mafuyu's, not so much.

Cafe Stile's chef.
- Accidental Pervert: After the manager brings in too many plants during a jungle-themed cafe during episode 7, Akizuki ends up getting lost trying to find his way around the restaurant. He accidentally gropes Kaho's breast, but interestingly she doesn't seem too upset by that. However, he immediately goes and grabs Dino's chest, and seems much more at ease doing this, which she says is much more irritating for some reason.
- Cannot Talk to Women: He is gynophobic, to the point that he even fears female storekeepers. He's barely able to talk to his female coworkers, and some Ship Tease moments that happen with Kaho ends up flustering her because of his inexperience with women.
- Demon Head: His head can look like that of an Oni when he's angry.
- Distracted by the Sexy: Gets flustered when he sees Kaho in her swimsuit, despite his efforts to defy it. Kaho almost seems to take this to her advantage.
- Ensemble Dark Horse: In-Universe Example. On a promotional activity, Stile prepared cookies with message cards written by the waitresses. At the end, at least one customer's suggestion card requested message cards from him, implying he has his share of fans among Stile's customers, despite spending most of his time in the kitchen and out of sight of them.
- Friendless Background: In his Origins Chapter, he mentions that during his cooking training, he only spoke with convenience stall staff, thus implying he didn't have much of a social life to speak of.
- Girl-on-Girl Is Hot:
- His obsession with yuri makes him desire to witness female best friends doing casually intimate things together, like sharing dessert, examining and fondling each others bodies, etc. This makes him wish that the cafe, which is male orientated due to the waitresses being attractive female archetypes, had more female customers.
- In the second episode of the anime, Akizuki tests the idea of female customers by having Maika and Kaho feed each other dessert. He naturally gets pretty turned on by it. At the end of the same episode, the cafe gets a pair of female customers. But they're not exactly what Akizuki was hoping for.
- Innocently Insensitive: He doesn't mean to be rude around anyone but Dino, but he can say the wrong thing around Kaho often. For example, he tells her she doesn't look that different with make up on and, after Kaho gets upset, he tells her he meant that he already finds her cute enough without make up.
- Only Sane Man: Zig zagged. Initially, he's presented as the straight man who remarks on everyone else's antics. It's quickly revealed that he's a Yuri Fan, but he's quick to return to a more serious persona if the situation calls for it.
- Otaku: He has a yuri obsession, and sees the idea of girls doing stuff together in the stereotypical way you'd expect one to. He also refers to Maika as a "normal person" for her consistent Pop-Cultural Osmosis Failure, thus seeing himself as this trope.
- Temporal Theme Naming: Autumn (Akizuki).
- Tsundere: Unlike Kaho, he seems to be a natural. He has an obvious thing for Kaho, but tries to take a 'it's not like I really care' attitude around her while his blushes give away how he really feels. In fact, Kaho's skills of acting this trope were taken from him!
- Yuri Fan: One of his complaints about working at Cafe Stile is that the customers are all men, so there's no chance for him to fuel his craving for yuri. Yes, he used the exact word "yuri."
- Yuri Goggles: He mentioned he can instantly see yuri as long as there's a pair of female customers.I dig the sacred mystery and possibilities of allowable touching between girls.

Maika's older sister.
- Beware the Nice Ones: Very polite, kind, and gentle, but she will pull out a naginata if she thinks someone made her little sister cry.
- Big Sister Instinct: She's quite protective of her sister. Upon seeing Maika crying, she assumes Dino was responsible, and is quick to threaten him.
- Family Theme Naming: Aika's name sounds nearly identical to that of her little sister Maika.
- Hime Cut: She has the blunt bangs, bra strap length sidelocks, and waist-length straight hair fit from a daughter of a very traditional family.
- If You Ever Do Anything to Hurt Her...: She fully supports Dino being in love with Maika, but she warns him that she won't let him go unharmed if he ever does anything that makes her adored little sister cry.
- Keigo: Like her little sister, she always speaks in formal linguistics, and hails from a traditional Japanese family.
- Kimono Is Traditional: Due to being from a very traditional Japanese family, she's always wearing kimono.
- Naginatas Are Feminine: As part of her Yamato Nadeshiko setup, she probably carries this when she leaves her household, so Episode 9 shows one time when she actually wielded it to threaten Dino.
- Nice Girl: She's just as kind and sweet as her sister.
- Ojou: Her visit to Stile is another hint that the Sakuranomiya family is very wealthy. She arrives with a personal driver and several bodyguards, who wore formal suits and take up positions at the car and her booth. Maika, embarrassed by this display, asks her to visit like a normal person.
- Shipper on Deck: Not only is she surprised to see Maika's coworkers, but when she sees Dino, she attempts to ship him with Maika. Unfortunately, her actions end up having the same effect on him as his does towards Maika, like when she offers him rock-hard crackers thinking foreigners would like that.
- Yamato Nadeshiko: She plays the "traditional Japanese lady" angle straighter than Maika. In that the times we see her she's always wearing kimono, has a Hime Cut, wields a naginata, is polite and hospitable to guests at her home, won't forgive anyone who makes her family cry, and doesn't have a Foreign Culture Fetish.

Maika's older brother.
- Big Brother Instinct: Much like Aika, he's very protective of his younger sister, though he isn't quite as intense about it.
- Kimono Is Traditional: Like Aika, he's always seen wearing (male) kimono due to being from a traditional family.
- Shipper on Deck: He's very interested in seeing Maika and Dino get together, much like Aika.
A college friend of Mafuyu's who temporarily replaces an injured Akizuki as Stile's cook.
- Bunny-Ears Lawyer: She's shown to be a competent cook, but Mafuyu claims she has a troublesome personality.
- Gender-Blender Name: Ayato is a male name.
- Theme Naming: Continues the tradition of Stile staff members' names referencing seasons or weather: her family name contains 風, which means "wind".
A tall young man with a crush on Mafuyu. He works at a (normal) bookstore.
- The Faceless: He is never drawn with the upper half of his face.
- Manchild: This is Mafuyu's opinion on him, especially after noticing his going all Ocular Gushers over a Magical Girl movie.
- Only One Name: Only his family name is known.
