A list of characters from the manga series The Demon Girl Next Door (Machikado Mazoku) and its Animated Adaptation. Beware of unmarked spoilers, especially if you are only familiar with the anime.
Yuko "Shamiko" Yoshida
- Voiced by: Konomi Kohara
Yuko was extremely frail and unlucky since birth as a result of inheriting most of her family's demonic powers, and being proportionally affected more severely by the curse of the Light Clan as a result. She has little memory of her childhood due to her early illness and has suppressed most of what she did manage to remember. She would have died if not for extraordinary sacrifices made on her behalf, and even after recovering enough to leave the hospital and return to a somewhat normal life after her younger sister was born, she still got sick or passed out on a near-daily basis, having to make frequent emergency room visits, until her demonic powers and features awoke. Although her endurance remarkably improved, she remained embarrassingly weak, struggling with anything more than a few kilograms.
As Yuko grew up in an extremely sheltered environment, she is bafflingly naive and gullible. She is fiercely protective of her family, and will do anything in her power to protect them, even if all she can do is stand in the way and be a human shield, or suffer misfortune in their place.
- Adaptation Dye-Job: Her hair is distinctly brown in the original manga, but in the Animated Adaptation she's a redhead; her personality is certainly volatile enough to suit it.
- After-School Cleaning Duty: She's often stuck on trash disposal duty, being on the school health and safety commission.
- Art Evolution: In the first few chapters of the manga, her horns were less tightly curled, and had sharper and pointier tips. The Animated Adaptation preserves the early chapters' original appearance throughout.
- Bad Powers, Good People: She doesn't see any potential in her Dream Walker power, while even Momo can think of hundreds of evil uses for it as soon as she learns about it.
- Became Their Own Antithesis: Downplayed. As the series progresses and she grows into her role as a demon, her attitudes slowly shift and she starts to warm to the idea of things she would have never considered before her awakening. Many of the aspects of Yuko's demonic awakening really bothered her at first—over time she either stopped caring about them, or even embraced them and ran with it, but she's far from becoming truly villainous.
- When her mother told Yuko it would be up to her to master her powers of darkness to break the curse on their family, she felt weirded out enough to exclaim, "But doesn't that make me the bad guy?" While she reluctantly starts down the dark path out of a desire to help her family (and not being hungry all the time), it's not long before Yuko is proudly calling herself a villain without reservations. However, deep down she's still a good person at heart. Mostly. She'll never admit it.
- Her official demon name "Shadow Mistress Yuko" and the nickname it spawned, Shamiko; at first she thought the former was corny, and the latter was a Berserk Button. Now she even signs her schoolwork with the former, and practically everyone calls her by the latter. It's gotten to the point where she barely even recognizes her original name.
- When Ryoko praised Yuko for taking initiative towards becoming the ruler of the forces of darkness by training to fight Momo, Yuko questioned she'd ever be a leader of anything. By volume 4, she's calling herself the "Queen of Darkness," demonstrates an impressive feat of coordinating her entire network of friends and associates into action on short notice, and is looking with anyone else with useful skills, talents, or connections to bring into her circle.
- Her Crisis Management form and the Stripperiffic outfit that comes with it initially embarrassed her to no end and she refused to transform in public. By volume 5, Yuko's using it practically anytime it might be helpful: in gym class, while taking tests, climbing multiple flights of stairs, and so on. It still embarrasses her, but not enough to deter her from using it around other people, and she no longer cares much if anyone sees her in it. While she still wishes the outfit wasn't so revealing, her various attempts to change it have all ended in spectacular failures.
- Cute Little Fangs: She is a very pronounced example and they are notably conspicuous at nearly all times.
- Dark Is Not Evil: She is a demon girl empowered by chaos and darkness, but she's also a good and honest girl with commendable modesty and integrity...by non-demonic standards.Yuko: Cheating is something we must never do!
- Debt Detester: She's too honest not to repay her debts, meaning she can't fight Momo as long as she still owes her. Momo exploits this by giving her more and more things as an easy way to avoid fighting.
- Defeat Catchphrase: Her "Don't think this means you've won!" after a "defeat". Other characters like Momo and Lilith will occasionally borrow it when they themselves suffer a "defeat".
- Don't You Dare Pity Me!: She gets angry and pouty when she thinks someone's pitying her, though she's fine with genuine sympathy.
- Dream Walker: This is her primary demonic power, overlapping with Dream Weaver. She can enter the dreams of basically anything capable of dreaming, as long as she and her target are both asleep, and while there, she can manifest into being virtually anything she can imagine. Thing is, she doesn't have a very good imagination. At first, she thinks that it's a pretty lame power to have, until her initial uses of it show that her dream manipulation is just a Required Secondary Power for what she's really capable of: manipulating the subconscious mind of the dreamer, as dreams are the window into the subconscious. When she finds she can do things like plant unconscious suggestions, create phobias or cravings, or even overwrite emotions to make bitter enemies into grudging friends, she realizes her abilities are a lot more dangerous than she thought and is disgusted with herself, even though her friends remind her that all she had ever used her powers for is to bring happiness to the people around her.
- Embarrassing but Empowering Outfit: Her Crisis Management form◊ is embarrassingly Stripperiffic, but it does raise her pitiful physical abilities to something approaching normal.
- Embarrassing Nickname: She initially doesn't like her title as "Shadow Mistress" due to the connotations around the word 'mistress' (as in a Dominatrix, as Ryoko of all people implied). She comes to like it more when her teacher explains a mistress can just be a title of authority.
- Extreme Omnivore: She is a type 1 after years of extreme poverty, perfectly willing to eat Momo's horrifying-looking attempts at cooking.Yuko: I was really nervous going by looks alone, but this doesn't taste bad at all!Momo: Y-you think so?Yuko: It's hard on the outside and mushy on the inside, plus I can really taste the onions and salt.Momo: I'm not so sure that's a good thing...Yuko: It's just fine! Truly terrible food makes you go numb the moment you bite into it, and your throat will force you to throw it back up right away! Anything that doesn't cause that reaction is totally edible!
- Fantastic Arousal: Inverted; things done to her tail result in disproportionately uncomfortable sensations for her, though arousal is never one of them. If something happens to the spade tip at the end of her tail, she feels it all over her body. Momo pressed a bottle of frozen water to Yuko's tail once and she broke out into uncontrollable shivering, pleading with her to stop. Later, when Momo's cat Metako latched on to her tail and starting licking it, she felt like her whole body was being scraped by sandpaper.
- Gamer Chick: A trait mentioned not very often in the manga, and omitted in the anime. This is stated to be her hobby in the first volume's character bios, and in Chapter 40, her idea of a proper vacation starts with video games. Of course, because of financial constraints, she gets her games from the 100-yen bin of the local Game-Off.
- Height Angst: She doesn't like people pointing out her height. While she's not short by the standards of a Manga Time Kirara series, at only 145 cm tall (or 4'9"), she's still visibly shorter than her peers.
- Hopeless with Tech: Justified, as her family had never been able to afford any modern conveniences aside from a phone/fax, old CRT television, and a second-hand Super Famicom.
- Human Mom Nonhuman Dad: Her father was a demon, and she takes after him in more ways than having horns and a tail.
- Idiot Hair: She sports an ahoge that wiggles when she's flustered or upset.
- Ill Girl: One dose of the the Light Clan's curse on Lilith's descendents is already enought to put a person to this. Somehow she took the yet-unborn Ryoko's share of it, making her dying from it ten years ago; Seiko recalls she was "struggling with her respiratory tract" at one point. Seiko implies it would have been fatal without Sakura's intervention, and when Yuko makes contact with what's left of Sakura in her memories, she tells Yuko it was even worse than Seiko thought. Even that only prevents her from dying; she spent several more years in the hospital, and even after that, she often had to leave school early or miss it entirely because she was in the hospital so much, and running was out of bounds for her. Only after her demonic awakening she can be said to be somewhat healthy.
- Improbable Weapon User:
- In-Series Nickname: Her epithet "Shadow Mistress Yuko" gets shortened to "Shamiko", and eventually she is known under that name more than her actual name. When Mikan first calls Yuko by her actual name instead of Shamiko (being a new acquaintance and all), it takes Yuko a few seconds to realize Mikan was referring to her and even promptly lampshades how often she's called Shamiko instead.
- Informed Flaw: In Chapter 24 Yuko told Momo her "eyes are no good either". This is the only mention of her having poor eyesight; anywhere else in the series she is treated as having normal eyesight.
- I Owe You My Life: Played straight, with Sakura's core within her keeping her alive. When Yuko found out about this state of affairs, she wanted to remove Sakura's core and restore her for Momo's sake, but in Yuko's current condition, she'd die without Sakura's core. Momo demands of Yuko to not even think about removing it until she's much stronger and doesn't need Sakura's support.
- Jerkass to One: Many of her exchanges with Momo are dripping with contempt and hostility that she doesn't really show towards anyone else.
- Morph Weapon: She comes into possession of a magic staff that once belonged to her father, an instrument of chaos that can change into a wide variety of things depending on what the user is focused on. When it isn't being using in a particular form for a particular use, it's an ordinary fork. When Yuko needs an actual weapon, she makes it larger; forks are what she's most familiar with.
- New Ability Addiction: Once Yuko can activate her Crisis Management form with her own magical power, meaning she can now transform at will and doesn't have to be scared to do it, she starts using it practically any time she has to undertake any physical exertion, as it gives her about a 20% boost in her capabilities.
- Older Than They Look: Mikan was trying to act like a Big Sister Mentor until Momo explained, "that girl is the same age as us." Yuko is actually a month older than Mikan, and six months older than Momo. Her father's the same way, though not by natural means.
- One-Track-Minded Hunger: While not a Big Eater, Yuko was almost always hungry in the first three volumes due to her family's curse-induced Perpetual Poverty, and could be talked into pretty much anything by being promised a decent meal. When that aspect of the curse was broken, and she got a steady part-time job, she and her family finally weren't starving for half the month anymore. Even so, this background means she frequently morphs her Whatever Staff into dinnerware or kitchenware.
- Only Known by Their Nickname: It doesn't take long before literally everyone but Yuko's mother is calling her "Shamiko," even her own ancestor Lilith. She got so used to it that she even asked Mikan to not call her Yuko. It's played with even on the other side of the Fourth Wall; the character bios on Volume 4 refers to her as "Shamiko (Yuko Yoshida)".
- Ordinary High-School Student: Subverted. She claims herself to be this in the beginning of the series, yet as noted elsewhere, many things about her aren't ordinary. Nobody would see an extremely poor Ill Girl as "ordinary".
- Prehensile Tail: Yuko has a spade-tipped demonic tail that's longer than she is tall, and it can apparently be temporarily stretched even further◊. She can freely move it with conscious effort, and often pokes, prods, pats, or slaps people with its tip, or wraps her tail around them as a show of affection, though she's not capable of grasping very well with it. It's highly reactive to her emotions, and it often betrays her true feelings when she's trying to bluff, boast, or brag to save face. She finds it extremely inconvenient; it's a point of weakness as when something happens to the tip of it, she feels it all over her body, and all too often people will grab her by the tail when she's trying to get away from them.
- Prone to Tears: Yuko cries whenever she's feeling panicked or scared, which is pretty often. Her ancestor Lilith isn't much better.
- Red Baron: Yuko's mom chose "Shadow Mistress Yuko" as Yuko's epithet minutes after confirming the latter has some demonic powers restored. Yuko finds it incredibly lame.
- Reality Ensues: Her horns cause her considerable discomfort. Their weight leaves her neck and shoulder muscles feeling stiff and sore all the time, and she can't sleep on her sides because of them.
- Refusal of the Call: On the night Yuko gained her horns and tail, Lilith asked her to "wake up" but Yuko refuses. She still received "the Call", nonetheless.
- Reluctant Fanservice Girl: Her Crisis Management form's outfit is distressingly revealing to her, as she usually dresses extremely modestly, to the point one would never otherwise know she has a surprisingly attractive figure for her age and height. Not that anyone ever points it out.
- Sleeps with Both Eyes Open: She does this while using her Dream Walker powers on anyone but herself.
- Super Gullible: All it takes is a little fast-talk and Yuko will believe just about anything, no matter how ridiculous it might be. Momo and Seiko aren't above taking advantage of this.
- Take Me Instead: Somehow, Yuko took on the share of her family's curse that was meant for her as-then-unborn younger sister Ryoko ten years before the Present Day. Being already frail and sickly since birth, this put Yuko in critical condition, and she only survived through extraordinary sacrifices made on her behalf.
- Team Chef: While Seiko still cooks at home, Yuko effectively cooks for Momo and Mikan. Ascended to the point of Through Her Stomach in Momo's case.
- Tsundere: Yuko's one for Momo. She'll frequently do something nice, then claim she had a nefarious reason to do it.Yuko: D-don't get the wrong idea, Magical Girl! All of this nourishing food is just meant to help you cultivate more blood so I can steal it later! And, um... I can't think of any other reasons!
- Weaker in the Real World: Within a dream, she can conjure into being anything her imagination can come up with—unfortunately, with her being a bit of an airhead with an extremely sheltered upbringing, her imagination has trouble coming up with very much. Her Whatever Staff, already capable of defying the laws of nature in the real world, is practically a Reality Warper when she brings it into the dream world. Screw entropy, screw probability, screw thermodynamics, screw logic, if Yuko thinks it'll work, it'll work—the only catch being that doing the impossible in a dream is incredibly taxing on her very limited magical power and it quickly runs out; doing such things in reality is completely beyond her capacity. For now.
- Your Worst Memory: The time when she was an Ill Girl in the hospital dying from a double dose of the Light Clan's curse on her family. When she uses her Dream Walker powers on herself, she was trapped in this part of her memories, being attacked by syringes and IV drips in a labyrinthine hospital with no exit, to the point it took Momo with (temporarily) to become Yuko's vassal to make them family, as only another family member can enter a Dream Walker's dreams, so Momo can go into Yuko's nightmare to pull her out.
- Voiced by: Hitomi Ohwada
- Big Sister Worship: In spite of her being well aware of her sister's hopelessness, she greatly respects Yuko and sees amazing potential in her. Her baseless faith became stronger after learning that Yuko "defeated" Momo, which got exacerbated even further after it was "confirmed" that Yuko "recruited" Momo and Mikan into her "army".
- Camera Fiend: After Yuko buys her a camera, she seems to want to take pictures of everything.
- Child Prodigy: As a fourth grader she is already reading kanji-heavy ancient war manuals such as Six Secret Teachings and Three Strategies of Huang Shigong. While the version she reads has been rewritten for a modern audience, reading those books requires a level of abstract thinking few people possessed in the era they were written.
- Troubling Unchildlike Behavior: She's a bit too into the idea of Yuko taking over the world. When Yuko swaps one of her books of treachery and tactics for a children's book, Ryoko still manages to find dark themes and inspiration in its simplistic story.
- Wrong Genre Savvy: While she figures out that Momo is actually a Magical Girl, she believes that Yuko had actually converted Momo and Mikan into her subordinates like in a book she read rather than just being actual friends, as it should on a Schoolgirl Series. The girls don't have the heart to tell her the truth. Though, honestly, Yuko kind of has done that by becoming Momo's actual best friend, and later earning Mikan's loyalty by breaking her curse.

She comes off as something of a a ditz, and was admittedly very clumsy before she got married, but occasionally demonstrates impressive cunning. She hasn't aged a day since becoming her husband's vassal when they got married, and still looks to be in her early 20s despite being at least in her mid-30s. Maybe more. Maybe a lot more. Her past is largely unexplained and unknown.
- Almighty Mom: Once Lilith can communicate with the Yoshida family she tries using her status as "honored ancestor" to take control. It takes Seiko less than a minute to crush that idea.
- Bad Liar: She came up with a ridiculous cover story to explain her husband's disappearance. Ryoko saw right through it and assumed her father was in prison. Yuko believed every word.
- Mom Looks Like a Sister: She largely stopped aging when she became her husband's vassal.
- Parental Fashion Veto: She has a somewhat subdued reaction to Yuko's Crisis Management form.Seiko: Yuko... I think you should avoid wearing that outfit you had on earlier outside from now on. You'll catch a cold.
- Voiced by: Minami Takahashi
For most of the time she was sealed away, she was barely conscious and was only occasionally able to reach out to the dreams of her descendants. For reasons unknown even to her, about ten years before the Present Day she regained her full consciousness, and the ability to perceive the outside world through the Evil God Statue that is a Yoshida family heirloom. After Yuko managed to break a part of her family's curse, Lilith became able to speak through the statue and even animate it to a small extent.
She becomes part friend, part mentor, and part grandmother to Yuko once they're able to communicate; first through Yuko's dreams, then directly once she can speak again. Although she is extremely petty and self-centered, she can hardly be called unequivocally evil. She genuinely cares for her family, and wants what's best for them (or at least, what she thinks is best for them).
- And I Must Scream: In human terms, Lilith's seal translates to solitary confinement with complete sensory deprivation.
- Bargain with Heaven: While on a camping trip in Outer Tama, Yuko accidentally drops a bottle into the nearby headwaters of the Tama River. This unfortunately gets the attention of the river's guardian spirit, a mizuchi sealed away into a nearby mountain 150 years ago. It doesn't like its river being fouled, it doesn't like demons, and it especially doesn't like demons fouling its river. It pulls Yuko's consciousness into its sealed space, holding her captive, and refuses to let her go. Lilith, who is in a temporary body that was only expected to last a week, converses with the river god through a dream mirror and implores it to let Yuko go; the mizuchi agrees, on the condition that Lilith devote herself to purifying the river. On the eighth day, Lilith finds herself still alive-the river god is holding her to her agreement by keeping her soul bound to her new body as long as she picks up trash from the riverbank every day. She's dismayed with how far she's fallen, until passerby start thanking her for cleaning things up.
- Brought Down to Normal: When she temporarily took over Yuko's body, Lilith was very surprised at how weak Yuko was and how she had almost zero stamina, sore muscles from not being used to the weight of her horns, and blurry vision. One can guess that she was quite a bit more powerful back in the day.
- Can't Hold Her Liquor: Less than one can of alcopop is enough to make her tipsy.
- Dark-Skinned Blond: Has a light tan and blonde hair. Justified as far as her skin color is concerned, as she's from the Middle East, but not the hair.
- The Devil Is a Loser: The Lilith in this universe is as useless as Yuko, and does not have the Ill Girl justification.
- Distinguishing Mark: Her right horn is broken. She broke it by running into a wall in the dark, and she then got sealed before it grew back.
- Evil Is Petty: She keeps a journal of every time Momo was mean to her so she can one day get revenge.
- Evil Mentor: She acts as one to Yuko, teaching her how to use their familial Dream Walker powers, yet often denigrating her modesty and integrity as unbecoming of a demon.
- Fashionable Asymmetry: The outfit she wore while possessing Yuko for a second time had mismatched socks specifically because she finds it fashionable.
- Gone Horribly Right: Lilith pressures Yuko and Momo to make her a life-size vessel doll so she can fully experience life in the flesh again. They agree to do so, making one out of homunculus clay, and Sion Ogura estimates it'll only last a week before the body dies and Lilith's spirit is pulled back into her sealed space. On day eight...Lilith wakes to find her new body is still alive, and she soon learns that her one-week reprieve from her familiar sealed space and its on-demand comforts is now an indefinite sentence thanks to a deal with the guardian spirit of the Tama River.
- Hereditary Hairstyle: Yuko and Lilith have virtually identical hairstyles, only differing in color.
- Immortal Immaturity: Lilith in this universe acts like a bratty teen, being extremely petty, too much into fashion, and liking sugary drinks. Perhaps justified, as she was sealed in her late teens and simply never grew out of it.
- Ineffectual Sympathetic Villain: She technically has "take over the world" on her list of plans, but seeing as she's somehow more pathetic than Yuko, nobody (except Momo) really has a problem with her, or takes her seriously.
- Ironic Fear: She calls herself the "Witch of Eternal Darkness" but is afraid of the dark.
- Never My Fault: Lilith genuinely thinks Momo's mean to her for absolutely no reason.
- Really 700 Years Old: She's been there for several millennia. Yet, she looks (and acts like) a teenage girl.
- Sealed Evil in a Can: Sealed, yes, though it is somewhat questionable how evil she truly is regardless of her grandiose plans for world conquest. Even when Momo was just about ready to offer all her power to Lilith if it would save Yuko, she refused. She's petty and self-centered, yes, but maybe not that evil.
- Shameless Fanservice Girl: Lilith was an exhibitionist in the days before she was sealed, and apparently wants Yuko to follow in her footsteps.Lilith: Shamiko, why do you always wear that uniform to school?Yuko: Because it's the rules.Lilith: That's how they stamp out individuality and shackle you to the collective, then. You are a demon! An embodiment of chaos! You should oppose the status quo! Go to school buck naked!Yuko: I'D GET ARRESTED!
- Strong Family Resemblance: She has the same hairstyle and a very similar face to Yuko. Ryoko thinks Lilith is basically Yuko's Palette Swap.
Joshua "Taro Yoshida"
- Voiced by: Hideyuki Umezu
He is trapped in a sealed space bound within the mandarin box in the Yoshida's apartment, which they use as a table and stool due to its magical protective coating. He is still watching over his family, encouraging and cheering them on, even if they don't know it.
- Catchphrase: "Ganbare!" which can be translated into "Do your best!" or "Hang in there!" depending on the context.
- Disappeared Dad: He is never seen, aside from a photograph, though Seiko has some outrageous explanations as to where he is. He was actually sealed inside the cardboard box in their house this entire time.
- Hereditary Hairstyle: He has a shorter version of Yuko and Lilith's hairstyle.
- Narrator All Along: Near the end of the second volume of the manga, and the anime's last episode, the voice of the narrator who occasionally speaks up to give Yuko encouragement is revealed to be that of her father, who's been there all along sealed inside a cardboard box, but is still watching over her. As Yuko gets closer to Momo and Lilith, he even starts encouraging them too.
- Naturalized Name: As a middle-easterner, Joshua (pronounced "Yoshua") adopts the Japanese name Yoshida as a disguise.
- Nice Guy: Based on the fact that he's the narrator, and his direct comments towards Yuko and others, he seems to have been a good, supportive guy, especially in regards to his family. Though going by a few of those comments, he could also be rather Innocently Insensitive at times.
- Older Than He Looks: A photo from Seiko shows he isn't too different from Yuko—he is shorter than Seiko and has a babyface.
- Phenotype Stereotype: He has blond hair, like Lilith. People from the Middle East rarely have that hair colour.
- Sealed Good in a Can: He was sealed inside the box their family had been using as a table ten years ago. Seiko proceeds to rename it the Daddy Box.
- Sue Donym: He cunningly adopts the Japanese name Yoshida as a disguise. Yuko lampshades how lazy an alias it is.
- Vocal Dissonance: The voice the anime gave him (which wouldn't be out of place being used for somebody's grandfather) probably is a good match for his true age, but it definitely doesn't match his appearance.
- Benevolent Boss: Though he pushes Yuko and Liko to work long hours, he's considerate of his employees and very protective of them.
- Fortune Teller: It's what his species specializes in, though he himself is out of practice. Some people are just easier for him to read than others, though.
- Four Legs Good, Two Legs Better: Although it's painful for him to walk on two legs, he does it in order to blend in better while living among humans.
- Funny Animal: He is a talking tapir who completely follows a human way of life. By "tapir," we mean he's physiologically a tapir—to the point that he finds walking on two legs hard on his back, but still do it anyway because he believes it's A Form You Are Comfortable With.
- Non-Action Guy: His species has no combat capability. Instead, their main power is prophecy.
- The Prophecy: After learning that Yuko can dive into dreams, and seeing her Whatever Staff in action, he has a premonition that Yuko has incredible potential and was meant to fulfill some great purpose, and that she needs to be kept safe in the meanwhile.
- Blue and Orange Morality: She has no grasp of the concepts of good and evil. She does nice things to people she likes, and...not nice things to people she doesn't.
- Foxy Vixen: Huli jing is a species of fox-women, and she inherits their moral ambuigity.
- Ignored Enamored Underling: She has a crush on Shirosawa, but he only has eyes for his own species.
- Master of Disguise: Zigzagged; her shapeshifting power lets her perfectly mimic the appearance of other people, but she's a terrible actor and her habits and mannerisms give her away. When Lico tried to impersonate Yuko to get closer to Momo to learn more about her, Momo immediately saw through it because she didn't act like Yuko at all.
- Older Than They Look: She's at least fifty. Shirosawa says, "she has walked this earth a lot longer than most [demons]."
- Ridiculously Cute Critter: Her proper fox form is absolutely adorable. Even Momo can't resist snuggling with her.
- Schmuck Bait: She's not above using her magic to create traps, or turn a drink poisonous to get rid of an unwanted guest, but it's really obvious at a glance when she's trying to do it.
- Shapeshifter Default Form: Her preferred appearance is as pictured, a human-looking girl with fox ears and a tail, but her "real" form is a small white fluffy fox.
- Super Hearing: She overheard a whispered conversation between Momo and Mikan from about twenty meters away.
- Supreme Chef: She has decades of experience across many countries and with many types of cuisine, and uses her magical powers to give the food other effects.
- You Didn't Ask: Lico had been enchanting the cafe's food to give it an extra effect of relaxing the person who eats it and letting them forget their troubles for a bit. While not harmful in small amounts, eating too much of it becomes a problem. She never bothered mentioning the negative side effects of her magical cooking until it made Yuko hyperactive and forgetful after she ate a large amount of the cafe's leftovers. Even Shirosawa didn't know she was doing it.

Ten years before Present Day, shortly after Sakura left her in another town for safety, her sister disappeared from her life, and Momo spent many long years searching for Sakura's whereabouts. In the meanwhile, she apparently worked with other Magical Girls, and even saved the world with them once. During that time in active service, she saw enough very bad things to drive her to put away her wand and give up the Magical Girl life, though she still has her powers. They're handy sometimes.
When she first met (and was then attacked by) Yuko, she was merely interested in getting close to Yuko and her family for information concerning the whereabouts of her sister, and even attempted to stalk Yuko only to be thwarted by Sakura's barriers. However, while training her to use magic, Yuko revealed that she didn't have any of the malevolent feelings toward the world that Momo imagined demons would have, and Yuko just wanted everyone to get along well and be friends. In light of that, Momo genuinely tries to become her friend.
Their relationship grows deeper upon learning of their intertwined past, becoming more of a sisterly nature, though Yuko is still hung up on seeing Momo as a rival, driven to defeat her and earn her respect, and is too naive to see she has already won her love.
- Bonding Over Missing Parents: The revelation that Momo's adoptive big sister who raised her also saved Yuko's life, yet sealed away Yuko's father, becomes the thread that binds them together as true friends.
- Butt-Monkey: She ends up being this more often as more and more characters start mercilessly teasing either her aloofness or her affection for Yuko.
- Calling Your Attacks: Her Magical Incantation is "Fresh Peach Heart Shower!" She finds it pretty embarrassing.
- Clingy Jealous Girl: She gets grumpy whenever she sees Yuko and Mikan acting close, something Lilith notices and teases her for. She mostly grows out of it after learning to open up to others a bit more.
- Covered in Scars: Her body has a lot of scars due to ether bodies being faster to heal but easier to scar than a normal one, the most prominent ones being four parallel scars on her left hip that look like claw marks.
- Disappointed by the Motive: Her own motive, no less. She spontaneously fell to darkness again due to a buildup of negative emotions. She finds their trigger so embarrassing she genuinely considered staying fallen rather than admitting them. What was it? She missed her chance to eat Yuko's cooking.Lilith: And you fell to darkness just because of that?Momo: Here's to my petty and boring life...
- Empty Fridge, Empty Life: Her empty fridge sadly matches her empty house. Specifically, despite living in a Big Fancy House, her fridge only contains a small amount of processed food.
- Fangirl: Of Tamasakura, the local mascot. She claims she's not a fan of Tamasakura despite knowing a ton of trivia on her, collecting her merchandise, going to movies about her... Tamasakura actually just reminds Momo of her vanished adoptive older sister. And she's right—Shirasawa designed Tamasakura based on Sakura's core, moments before it sealed itself in Yuko's body.Momo: It's not like I like her. I just care enough that it impacts my daily life.
- I Didn't Tell You Because You'd Be Unhappy: Momo never told Mikan about Sakura's disappearance, despite them being longtime friends who both mentored under Sakura, and Mikan is understandably distraught when she finally finds out.
- Kind Hearted Cat Lover: A trait only appeared in the unanimated chapters. Playing with cats is one of the two things (the other being bodybuilding) she still enjoys, to the point that in Chapter 48, she attempts to start a school club for exactly that purpose.
- Lethal Chef: In her untransformed state, Momo simply can't cook anything without doing strange and bizarre things to either the ingredients or the final product, and only Yuko can stomach her culinary handiwork. Apparently her cooking hasn't improved a bit from when she was 5 years old.
- Magic Wand: She has one called Heartful Peach Morphing Stick which looks like an archetypical magical girl wand. It changes her clothing by Gorgeous Garment Generation, and she uses it instead of getting dressed in a normal manner to keep her scars hidden.
- Minor Living Alone: She lives alone in a large house. She apparently inherited it from Sakura along with a rather sizable fortune.
- Mundane Utility: Since she rarely has much to do in recent times, and Yuko is too weak and hopeless to be a threat, most of the time she uses her Magical Girl powers for random lowkey situations, such as saving hot-dog-octopi from falling on the ground or making special protein shakes.
- Muscles Are Meaningless: Zigzagged with Muscles Are Meaningful. Her incredible strength is a result of her magic power supplementing her physical abilities, though she also needs genuine muscle to increase her power.
- Please Don't Leave Me: The only vow she asks of Yuko in exchange for becoming her vassal is that Yuko won't leave her.
- Rose-Haired Sweetie: Momo is a heroic Magical Girl who helps and trains even her rival Yuko.
- Secretly Selfish: At least part of the reason she got close to Yuko was in the hopes of getting information on her missing sister. Yuko is completely understanding when the truth comes out.
- Shell-Shocked Veteran: She has been a magical girl since the age of four. While what happened on her battles were never mentioned, Mikan reflected she was a Genki Girl when she was younger. At Present Day she emotes very little, admits she has no goals in her life, and seems to have given up taking care of herself, if her eating habits are any indication.
- Significant Wardrobe Shift: Momo goes through a few stages of this.
- After Yuko asked her to become her vassal, she started dressing in black and wearing more casual attire, as opposed to always wearing her usual yellow parka over her school uniform.
- When Yuko bought her a pair of black hairclips as an Apology Gift, she wore them from that point on, and never wore her old pink hairclips again.
- After temporarily becoming Yuko's vassal to save her from a nightmare she couldn't wake up from, her hair ornament (which is actually part of her ether body) changes from pink to black, with a white angel wing. Also, she took to wearing the black hairclips crisscrossed on the right side of her head, instead of over her bangs.
- When in her full fallen state, her transformation takes on a complete Evil Makeover, and the wing on her hair ornament turns into a black bat wing even when not transformed.
- Smells Sexy: After Momo's partial fall to darkness to save Yuko from her nightmare, and her hair ornament turns permanently black, something changes about her ether body that makes Yuko become enamored by her smell.
- Sympathy for the Devil: When Momo tried to bribe Lilith for information about Sakura with an offering of an armful of junk food (considering Joshua used to carry her statue around back then the way Yuko does now), Lilith said she knew nothing. Momo immediately takes it all back. Lilith then adds she didn't know because she'd had no awareness of anything outside her sealed space, completely isolated and alone, for two thousand years. She didn't regain awareness of the outside world until after Sakura had disappeared. Momo is stunned into silence and gives the offering back to Lilith; she even cries just a little bit.
- Unskilled, but Strong: For a Magical Girl, she is actually not particularly good at using magic. She makes up for her magical shortcomings with physical force, which is why she is obsessed with working out.
- Used to Be a Sweet Kid: She's stoic and jaded now, but she used to be a traditionally peppy and cutesy Magical Girl.
- When She Smiles: Yuko thinks she would look really cute smiling and makes it her mission to see it. And when it finally happens, Yuko completely breaks down sobbing in tears, both because she was happy that it happened, and because she didn't feel she deserved it.
- You Are Not Alone: Momo had been looking for her sister for years, without success due to the Magical Girl-repelling barriers around the city. She only got close to Yuko with the intention of getting information from her family, the only members of the Dark Clan she ever managed to make contact with, and never counted on Yuko becoming someone so endearing to her in several ways. Momo felt personally responsible for Sakura sealing away Yuko's father and was so bothered by it that she didn't see the situation from the other side: Sakura saved Yuko's life, and Yuko feels she owes her a massive debt for it. When Yuko tells Momo they both have reasons to find Sakura, she'll do anything she can to help, and that Momo is not alone in her search anymore, Momo is so touched that she nearly accepts Yuko's offer to become her vassal to get around the barriers, until realizing the consequences of it.

She bore a curse for many years, after her father made an attempt to summon a demon that went terribly wrong as he didn't know what he was doing. The summoned demon, named Ugallu, took host in Mikan's heart, trying to fulfill its intended purpose by blindly lashing out at everyone and everything around her when it sensed her in distress. This curse was originally much worse, and nobody could even get close to her without being hurt, however, Sakura Chiyoda helped her out by using magic to suppress the curse a bit. She even devised a way to undo Mikan's curse, but was unable to carry out the plan she came up with due to...other factors. Since Sakura's battle with Ugallu already destroyed the factory owned by her father, they moved to the west using the money Sakura gave them in lieu of Hero Insurance.
Momo called on her to help protect Yuko after Yuko unwittingly took some of Momo's blood and partially broke her family's curse on accident, which drained a large amount of Momo's magical potential. Yuko and Mikan became good friends as well, though not as close friends as Momo and Yuko are.
Her family owns a fruit processing plant that specializes in making candies and confections from citrus fruits.
- Adaptation Dye-Job: Her eyes go from an amber orange in the manga to green in the anime.
- Bizarre Human Biology: That green ribbon she wears? It's actually a part of her ether body.
- Blessed with Suck: To some degree. Ugallu resides in her because of her mana reserves, but this is also why Sakura selected her as a Magical Girl as well.
- Equippable Ally: Her Navigator Michael turns into an arrow during combat. Due to Michael's deadly toxin Yuko is a bit disturbed by this.
- The Jinx: Due to a curse, whenever she gets worked up, misfortune befalls the people around her, such as trash-bags exploding, strong gusts of wind or storm clouds coming out of nowhere, or a snake showing up to torment Lilith.
- I Am a Monster: Her line of thinking when she's feeling especially down. It usually takes some external intervention to snap her out of it.
- Improbable Aiming Skills: She can hit a target the size of a standard A4 piece of paper from a kilometer away, though she does so by magical assistance.
- Long-Range Fighter: Mikan's great at sniping things from afar, but she gets too nervous to hit when the target is close.
- Nice Girl: She attempts to mask it on rare occasions (because getting emotional triggers her curse), but she always tries to be cheery and helpful despite her condition. Small wonder that, the one time things got unbearable for her, every named character (and even some unnamed characters) showed up to help.
- Team Mom: Probably the most well-adjusted person in the group, which is not saying much. It eventually turns into an in-series nickname after she really does become a "mom" of sort.
- Trademark Favorite Food: Citrus fruits. She will subconsciously buy a large amount of citrus fruits every time she visits a supermarket, and have the tendency to put citrus in every kind of food.
- Vitriolic Best Buds: Momo spends most of her time taking the brunt of Mikan's curse, while Mikan usually has to deal with Momo's largely unreasonable requests. When pressed about it, she reminds Yuko that they couldn't have remained friends for ten years if their relationship were shallow. On one side, Mikan would do just about anything for Momo, and on her part, Momo's trust in her is more or less absolute.
Sakura was extremely adept at manipulating seals and barriers; she is responsible for the barriers around Tama that normally keep Demons and Magical Girls from being able to interact with one another. Whatever motivated her to do something so drastic remains unknown, but at least we know her reasoning. From Yuko's limited contact with Sakura within her own subconscious, Sakura claimed she and Yuko think alike: they just want everyone to get along together.
Sakura raised Momo like a daughter, training her as a Magical Girl. Momo remembers her as being very skilled with magic, but very bad at managing her time and never getting her college coursework done before it was due. Sakura was also a mentor to Mikan, and suppressed her curse enough to at least allow other people to get near her without the demon inside her critically injuring them.
She meddled in the ancient curse afflicting the Yoshida family in an effort to save Yuko's life at Joshua's behest, sacrificing their family's luck and fortune for Yuko's healthand yet even this wasn't enough. This took a major toll on her magical abilities, and in return for her intervention, Joshua became her partner in protecting the city of Tama, in a time where things were much more dangerous than Present Day.
What exactly befell her and Joshua ten years ago is unknown; we only know the final outcome. They confronted something dangerous at the factory formerly owned by Mikan's family and Joshua got sealed into a box. Sakura destroyed the factory warehouse with her strongest attack in the fight. Afterwards, she took Joshua's box, and left it at his family's apartment with a note explaining what had happened to him—and then disappeared from public view.
- Adoptive Peer Parent: Sakura adopted Momo when she was still in college.
- All-Loving Heroine: She set barriers to defend demons despite being on opposing sides. Mikan thinks she'd be far more kind to Lilith than Momo is.
- Big Good: She is an experienced Magical Girl fights evil, protects innocent demons, and even saved Yuko's life in the past. Too bad she's been missing for years now.
- Book Dumb: Information about her is scarce, but the short note she left for Seiko about Joshua already has two errors, in addition to having fewer kanji than expected for a college student. This indicates her book smarts may be limited.
- Cherry Blossom Girl: She is clearly cherry-blossom themed: she has "Sakura" as her first name, she has pink as her Color Motif, and even her Finishing Move Sacrament Cannon leaves holes of that shape on walls.
- Fiction 500: The fact that she can actually purchase large amounts of land on a whim or in lieu of Hero Insurance puts her into this trope. Momo inherits her fortune, but she's too lethargic to use it.
- Idiot Hair: She has a very small one on the top of her head, in a similar position as Yuko's.
- Sealed Inside a Person-Shaped Can: Sakura's core is sealed inside Yuko. Sakura actually did this to herself to boost Yuko's health. Yuko would die if it was removed before Yuko has the power to resist her family's curse alone.
- Voiced by: Sayaka Senbongi
- Genki Girl: The most energetic girl of the cast, also acting sporty, and she gets Yuko into many things.
- Information Broker: She acts as this (for free of course) towards Yuko, who, due to being an Ill Girl for most of her life, doesn't know much about the town she lives in.
- Innocently Insensitive: Although she means well for Yuko, she has a habit of letting slip things that Yuko would rather not have mentioned, to the point where Yuko wonders if Anri secretly has it in for her. This is why Yuko sometimes says she's an assassin.
- Religious and Mythological Theme Naming: Her name comes from Satan (Sata Anri).
- Voiced by: Ayaka Suwa
- For Science!: She doesn't let unnecessary things like "ethics" get in the way of her black magic experiments.
- Mission Control: In later volumes, her plans and quick thinking become critical to the cast's success in facing various crises.
- Muggle with a Degree in Magic: She has a deep understanding of black magic. While she can't use the magic herself, she has successfully prepared different magical potions.
- Non-Action Guy: She's the least physical of the entire cast—Yuko, at least, runs slightly faster than Sion and attempts to be more physical, while Sion is rather content in her role as the local Mad Scientist.
- Religious and Mythological Theme Naming: Her name comes from Gusion (Ogura Sion). She even signs her name as "Gu-sion" on one of her plans once.
- Smart People Wear Glasses: She's the only glasses-wearing character in the cast and also the smartest of the bunch.
- Stalker Without a Crush: While already an indirect friend of Yuko's, through Anri, after Yuko awakens as a demon, Sion starts taking more than a casual interest in her, watching her from the shadows. She finally invites Yuko to her black magic lab, wanting to conduct experiments on her, plants a microphone in Lilith's statue, and in the fourth volume, surreptitiously moves into the attic of Yuko's apartment complex.
- Teen Genius: The top student of her grade and the only potion maker in the setting.
