    Ryuuichi Kashima
"We really aren't alone, are we?"
Voiced by: Kōtarō Nishiyama (anime), Yuki Kaji (drama CD)

"God, thank you for not taking Kotarou away from me too. It's pathetic, but I think I'm probably the one who's being saved by Kotarou's warmth."

Ryuuichi is a high school student who lost his parents in a tragic accident, being left to care for his little brother. He works at the school's daycare as a way to pay for his stay in the Chairman's house and works hard towards taking care of his little brother and the kids of the daycare. He is known as an "ideal big brother", who embodies everything a Cool Big Bro has to be in it's entirety.

  • Adult Fear:
    • He reacts with utter fear and often desperation when one of the kids gets lost. After all, he needs to watch over these children and the idea of something happening to them terrifies him to his very core, such as Kirin jumping from a high stair to try to fly, Kotarou getting lost in a trip, a child lost in a snowstorm, etc.
    • He sometimes delves into the fact that he, still in high school, is a little kid's only living relative and now the one responsible for him. He wonders what will he do once he leaves the Chairman's house to sustain them both, but at least he is optimistic about the future.
    • His fever dream is a nightmare of his parents taking Kotarou with them on their ill-fated trip while he's stuck behind an invisible wall and powerless to stop them. Kotarou is also the only relative Ryuuichi has left as well, and Ryuu is terrified of losing him and being left alone.
  • Affectionate Nickname: Gets called "Ryuu-chan" by Usaida. The kids also tend to shorten his name to "Ryuu". Kirin calls him "Ryuu-nii-sama"note .
  • Animal Theme Naming: His name "Ryuuichi" refers to dragons. Combined with his little brother's Tiger themed name, they form a reference to Tiger Versus Dragon.
  • Attractive Bent-Gender: While disguised as a girl during the cultural festival, Inui falls in love with him, thinking he is a girl called Inomata. After a few mishaps, he reveals his identity to him, but Inui's feelings for Ryuuichi are apparently more complex than that.
  • Beware the Nice Ones: Ryuuichi is a very kind and polite boy the majority of the time. The few times he's angry usually indicates something's gone really wrong.
    • Ryuuichi respects his elders and teachers, but he angrily shoves his reflection piece in Hebihara's chest after he sees how hurt he made his own son Kamitani feel in chapter 25.
    • Although extremely rare, Ryuuichi can be stern with the babies, like in chapter 38 after they lock Usaida out of the babysitting club room.
    • Running away with Kotarou right in front of him isn't wise, as the otherwise carefree and friendly Ryuuichi will chase you down with the determination of a buck as Inui was going to find out in chapter 53.
  • Big Brother Instinct: His first instinct at all times is to check on Kotarou and the kids. If anything happen to them, he will drop everything and do anything to go to their aid. At one point, he chases Inui when he thinks he might harm Koutarou with a terrifying expression in his face.
  • Bishōnen: A lanky attractive guy of the "cute" variety, and part of the reason for his popularity with girls.
  • Chaste Hero: His lack of interest in dating is sometimes brought up:
    • He decides that his priority should be Kotarou and he should focus on his work at the daycare. As a result, he decides he doesn't have time for romance and turns down a girl who confess to him. Though early on, he admits to have never really liked anyone, so he doesn't really care for romance that much anyway.
    • The mothers at one point are surprised by the fact that, when they dress up Inomata, his only comment is that her bikini looks nice because it matches Kirin's floaty.
  • Clueless Chick Magnet: He is not aware that he is among the most desired guys in the school, because he focus almost all of his time in the daycare and his little brother. He admits in a chapter to not have ever liked someone and hasn't really thought about it much. He seems to just not be wired for romance.
  • Cool Big Bro: His skills in being a big brother are acknowledged as borderline legendary. Inui's younger sister has asked him to be his big bro instead of Inui, some of his classmates have called him "the ideal onii-chan" and even voiced that they wanted to call him onii-san too. All the children also consider him an honorary older brother to them.
  • Cry Cute: Still looks cute when crying. Too bad you can't really appreciate how cute he looks since it happens in one of the most heart breaking moments in the series, when he breaks down after finally accepting his parents' deaths.
  • The Ditz: While not Too Dumb to Live or Book Dumb by any means, his pop culture ignorance and relative awkwardness when dealing with women make him come off as dense at times, which his classmates notice.
  • Fatal Flaw: Ryuuichi has a very hard time asking for help or relying on anyone to help or care for him. This has been noted and sometimes even lampshaded by a plethora of characters including the Chairwoman and Usaida (both on chapter one), Inomata and Kamitani. As a direct consequence, he tends to blame himself for everything.
  • Friend to All Children: He actually manages to make a baby stop crying just by holding him. All the children absolutely love him and he loves all of them in return. He generally tends to be really good with children, as a result of taking care of Kotarou while they were younger.
  • Hero with a Unique Name: While he's also part of the Animal Theme Naming convention like the other character, Ryuuichi differs due to how his first name translates to "dragon", a mythical animal instead of a regular one like the rest.
  • Naked Apron: Played for Laughs. At one point, he has nothing to wear after getting wet on a summer day and decides to just use pants and his daycare apron, which causes Inui to blush picturing him (with a wig) in a naked apron.
  • Not So Different: When he is deep in thought, he tends to space out and stare, at which point, he will start behaving a bit like his little brother. At one point when he is in this stage, his face even looks like Koutarou's. He also shares Kotarou's sparkly eyes when excited.
  • Oblivious to Love: Inomata and Ushimaru are competing for his affection and, apparently, half of the women in his class are interested in him. He remains completely ignorant of this fact, in spite of the fact that everyone else (with the possible exception of Kamitani) is aware of that.
  • O.O.C. Is Serious Business: Ryuuichi rarely scolds the kids even when they are naughty but one chapter has him scolding the kids for locking Usaida out of the daycare on a cold day (earlier of the chapter, the twins locked their father on the balcony while Taka locked his brother) as he realizes that strictness is the only way to make sure they learn their lesson. This is a serious lesson for the kids, since it's quite dangerous for adults to be locked out of a room with little kids inside; if there was a fire or one of the kids got hurt, the adults wouldn't be able to help them.
  • Pop-Culture Isolation: He only watches educational programs that Kotarou likes and spends the rest of the time either at the daycare or studying. As a result, he is unaware of popular culture in current times, not even knowing who the twin's father Kousuke Mamizuka is, despite him being a very popular actor. invoked
  • Promotion to Parent: Ryuuichi already had to look after Kotarou a lot while their parents were traveling or busy with work, but now that their parents are dead he's become the main person who's responsible for his little brother.
  • A Protagonist Is Ryu: The Affectionate Nickname given to him by Usaida and the kids is a shortened version of his first name, "Ryuu".
  • Sensitive Guy and Manly Man: Ryuuichi is the sensitive and sweet Cool Big Bro to Kamitani's brash and violent Aloof Big Brother.
  • Shared Family Quirks: Ryuuichi is a lot more upbeat than his younger brother, but he makes the exact same dull look when he's zoning out. Also, during the chick hatching, both brothers have the same excited sparkles and stars in their eyes.
  • Team Mom: Among the members of the babysitter club, he has the most natural talent at taking care of kids and possesses a lot of House Husband traits.
  • Wise Beyond Their Years: Very mature and level headed for his age, which may be a result from always taking care of Kotarou.
  • You Are Not Alone: The aesop he receives in chapter 1. He misses his parents greatly, and finally realizes that his parents will never come back. However, he notices that he still has not only Kotarou but also the chairman and Saikawa, and their relationship with the others is growing, so he doesn't have to face it alone.

    Hayato Kamitani
Voiced by: Yuichiro Umehara

"I hit people who don't do what I say. I'm not going to treat him differently just because I'm looking after him."

The older Kamitani brother. He is rude, cold and stoic, often correcting his brother by hitting him in the head rather than talking. He tends to be more willing to use strength to solve problem and correct behavior around the day care and has a cold relationship with his father.

He is very passionate about baseball, being the star member of the academy's rather weak baseball team.

  • The Ace: Considered to be the best player on the academy's team. However, he considers the team to be very mediocre and doesn't see something like that as an achievement.
  • Affectionate Nickname: "Kamita" and "Kami-chan" are some of the names that the kids in the daycare call him.
  • Aloof Big Brother: He often hits his brother in the head and calls him an idiot very openly. He does however, shows a more loving side, especially when his brother is in trouble or in relation to their father.
  • Animal Theme Naming: His family name contains the kanji for "wolf" and his given name means "falcon". This goes into Family Theme Naming as he shares the bird of prey theme with his brother, whose name means "Hawk".
  • Chaste Hero: While it's clear he doesn't has any interest in women and openly declines any of their affections, it's unknown whether he even understands that he is attracting women or he is aware and doesn't care.
  • Chick Magnet: One of the most desired guys, sharing the title with Ryuuichi. Different than Ryuuichi who is clearly very oblivious to the fact that women are attracted to him, it's unclear whether Kamitani is aware of the women's affections and doesn't care for them or he doesn't realize about it at all.
  • The Comically Serious: He always keeps the same expression even when he is joking.
  • Everyone Has Standards: He might scare people and welcome using force, but when a baby starts annoying him, he explicitly states that though he'd hit kids in Taka's age, he'd never hit a baby.
  • Generation Xerox: He really looks like his mother, having inherited almost no physical trait from his father, with the possible exception of the scowl. Interestingly enough, he has a personality extremely similar to his father, what with his no-nonsense attitude and having a Hidden Heart of Gold, which his mother appears to have noticed.
  • Hidden Depths: He cares a lot about his friends and family, just dislikes showing it clearly. He is ready to help around the daycare at any given time and he has more than once approached his father in an attempt to talk him into becoming a part of Taka's life (despite the fact that Taka is blissfully unaware of his father's even existence). In fact, during a Christmas, he says that the only thing he wants is to know when he is going to tell Taka he is his father, though he himself appears to have decided he doesn't want his father in his life.
  • Hidden Heart of Gold: Deep down, he is a caring person, who is very devoted to his little brother, though in a different manner than Ryuuichi's. He especially has shown more than once that he is very caring towards Taka, despite being tough with him.
  • O.O.C. Is Serious Business: Kamitani is grumpy by default, and has a habit of hitting Taka over the head whenever he acts out of control. But when Taka crosses the line by defacing his autographed baseball, Kamitani doesn't react by hitting Taka much harder. In fact, he completely ignores him for almost the entire day, and before Ryuuichi talks to him, is in a state of Tranquil Fury.
  • Perpetual Frowner: Tends to keep an angry expression at all times.
  • The Quiet One: He doesn't talk much unless necessary or spoken to.
  • Sensitive Guy and Manly Man: He is considerably manlier than the sweet polite Ryuuichi, being more physically stronger and more devoted to sports and even welcoming of the use of force.
  • The Stoic: He has a very serious face and very rarely emotes anything. In fact, he rarely seems to feel things beyond annoyance.
  • Strong Family Resemblance: He looks extremely similar to his mother, and they both share several similarities with his baby cousin who looks more like him than his own brother.
  • Tall, Dark, and Handsome: Not particularly tall (he's taller than Ryuuichi, at least), but does fit the dark and handsome aspect.
  • Would Hit a Girl: He hit Kirin upside the head once, with predictable results and chastisement from Ryuuichi.
  • Would Hurt a Child: Frequently hits Taka whenever he acts out, and has threatened to hit the other toddlers at least once before. Apparently got this habit from his mother who does the same to both him and Taka.

    Yoshihito Usaida
"Play till your heart's content"
Voiced by: Tomoaki Maeno

"Oi! Taka! I was having a good dream. What will you do to make up for that?"

The teacher responsible for the daycare. He used to study in the school before graduating and being inspired by the chairman's son to stick around as he was directionless, ultimately becoming the daycare's caretaker in the process. He is often sleeping and taking care of Midori while Ryuuichi looks after the other kids.

  • Animal Theme Naming: Keeping up with the rest of the cast, his name "Usaida" contains the kanji for rabbit.
  • Bishōnen: Although rather unkempt, he is still good looking, tall and slim.
  • Cloudcuckoolander: He is very out-there with his ideas and descriptions. At one point, when Takuma and Kazuma seem to grow distant, he pictures the scenario as a soap opera where they are a couple and Takuma cheats on Kazuma with Kamitani while the other seeks comfort with Ryuuichi. At other point, he describes Takuma, Kazuma and Taka fighting for Koutarou's attention as "Kotarou's Harem Battle".
  • A Day in the Limelight: Several chapters shed light on Usaida's past as well as his Hidden Depths.
    • Chapter 27 shows Yukari and Ryuuichi figuring out why he is always so sleepy and unintentionally delve into his past as well as his late night activities of teaching his neighbor.
    • Chapter 40 tells about his involvement in Midori's birth and how he and Yukari have become Platonic Life-Partners when he loses his keys and believes Midori has them.
    • Chapter 63 focuses on him taking care of Kotarou when Ryuuichi, Saikawa and the chairman all leave for a trip. Here readers (and Kotarou) find out he's interested in becoming a teacher.
    • Chapter 84 is about a dream he has where everyone except him swap ages.
  • Butt-Monkey: Out of the three baby-sitters, Usaida gets the least respect from the kids who aren't above insulting or tackling him amongst other things. Given his lazy personality, probably not unwarranted.
  • Has a Type: He likes girls who wear glasses.
  • Hidden Depths:
    • He is very dedicated to becoming a teacher someday, having been studying secretly and teaching his neighbor who wants to get high school degree. The end of chapter 27 shows that he is actually quite the hard worker and studies every night to become a teacher.
      Chairman's son: Despite his appearance, he is quite the hardworking fellow deep inside.
    • He is very observant and well aware of his surrounding (considering he takes care of little kids, he has to be), despite his quirky tendencies. He quickly notices things that are happening among the kids, teachers and students, and lays it out when Ryuuichi fails to understand it, such as that the Kashima brothers need to learn to speak up or the nature of any fight that could have happened.
    • He's very good with his hands, something Ryuuichi is surprised to find out. He makes the vegetable costumes for the culture fair and vegetable puppets in chapter 58, his snowman in chapter 61 is well done, and he has decent gardening ability and sometimes shares the food with others.
  • Hidden Heart of Gold: As the chairman's son was quick to notice, Usaida's odd and lazy behavior hides someone who has helping people as a second nature, which is the main thing that makes him offer him a job at the newly opened daycare.
  • Impoverished Patrician: Came from a family whose father ran a large company. However, it went bankrupt and his parents went into the countryside to be farmers, leaving him aimless.
  • Lazy Bum: Tends to fall asleep when nobody is looking and gets tired easily of playing with the kids. The kids also complain that it gets boring to play with him, because he gets tired so easily.
  • Mellow Fellow: Always chill and calm. He is very nice to everybody even if he is a little strange.
  • Neet: Joked about and discussed in chapter 4 when playing house with Kirin as her NEET son (yes she uses that exact term). Chapter 27 reveals he was similar to one or even worse, sleeping for a year with no work nor additional schooling to do (as a reaction to his father going bankrupt and becoming a farmer) — ever since then, he is working to become a teacher albeit slowly.
  • Nice Guy:
  • Odd Friendship: Shares some sort of friendship with Saikawa who could not be any more opposite in terms of personality. They go drinking in one chapter and he is considered a friend by him in later chapters despite not knowing anything about him.
  • Parental Substitute: He's a downplayed example towards Midori, who is well aware of both her parents and loves them. However, she's probably around Usaida more than her real father (who is busy with his archaeology work), he takes care of her the most out of the other kids, and her first word may or may not have been his name (which even annoys her mum Yukari), which gives an indication of how comfortable she is with him.
  • Porn Stash: Doesn't bother hiding the stash of porn magazines he has in his apartment; of course, he never has anyone over, so it's not like he has to. Kotarou accidentally stumbles upon them when he spends a night at his apartment (amusingly, he goes out of his way to hide the book on becoming a teacher but not the magazines).
  • Running Gag: His constant complaints about his small paycheck and his ideas on how to get money on the side, which includes selling cute pictures of the toddlers.
  • Sleepyhead: He is always shown to be sleeping that at one point. At one point, Ryuuichi begs him to go to the hospital to check if he has narcolepsy or some sleep-related illness. Justified when it's revealed he is constantly up late at night tutoring his neighbor for the GED.
  • You Gotta Have Blue Hair: He has pink natural hair.

The Kids at the Daycare

    Kotarou Kashima
Voiced by: Nozomi Furuki (anime), Megumi Takamoto (drama CD)

"Nii-chan! Don't go to the sky… Ni-chan. Nii-chan, don't go."

The younger Kashima brother. Kotarou is a well behaved, sweet, and somewhat stoic kid who sometimes acts as someone older than his own age. He is extremely close to his older brother, specially following the death of their parents.

  • Alliterative Name: Kotarou Kashima.
  • Ambiguous Disorder: Unusually quiet for his age group, and when he does speak it's very little and in broken sentences. One of at least three things is possible: A) His vocabulary isn't fully developed yet. B) He is a really quiet child. or C) He has selective mutism. He's been strangely quiet ever since he was a baby, which made Ryuuichi worry at the time.
  • Animal Theme Naming: He has the kanji for "tiger" in his name, and he also often wears tiger printed clothes. Combined with his older brother's dragon themed name, they form a reference to Tiger Versus Dragon.
  • Baby Talk: Sometimes, Kotarou can speak somewhat normally, but mostly, he speaks in broken sentences and incomplete words. Often, he also simply says, "Ung," which most often is his way to say, "Ok."
  • Big Brother Worship: Extremely close to Ryuuichi. He looks up to him and a lot of what he does is in a way or other to please his older brother. It actually extends to the point that it is inconceivable to him that anyone could dislike his brother in any way, or imply that he is less than perfect. With the age difference and their parents no longer here, this is probably a given.
  • Bishōnen: Grows up to be a slim and handsome teen if episode 3's end card and Usaida's dream of him as a student is anything to go by.
  • Catchphrase: Says, "Ung!" the most, due to his quiet nature and his speech likely not as developed as the others.
  • Character Tic: Has a habit of nodding his head to communicate. He even does it over the phone.
  • Cute Bookworm: He is a fan of picture books, always asking for Ryuuichi read to him. He is specially fond of a series of children's books focused on a panda.
  • A Day in the Limelight:
    • Chapter 17 has Ryuuichi forgets his lunch in the daycare, so Kotarou goes into a "first errand" style trip around the school to give him his lunch in his homeroom.
    • Chapter 39 is a heartbreaking one, which focus on Kotarou, after hearing about Kaguya-hime's story, fearing that his brother will leave if he doesn't get him a precious gift like the ones Kaguya asks for in the tale.
  • Determinator: The Chairman and other students notice that, when Ryuuichi is the subject, Kotarou isn't easily deterred. He faces stairs he can't go up easily to deliver his older brother's lunch and tries to learn kanji so his older brother won't have to read things for him while he is going through exams week.
  • Fanboy: He is especially fond of a series of children's books focused on the Teary-eyed Panda.
  • Innocently Insensitive: Him pointing at Chairman Morinomiya and calling her Shaggy is a simple observation of her hair on his part, and he means no ill will when he says it despite her negative reaction to it.
  • Living Emotional Crutch: Ryuuichi quietly realizes to himself that it is Kotarou's presence that is helping him through the trauma of losing their parents.
  • Not So Stoic: Calling toddlers stoic is a bit of a stretch, but in comparison to his fellow toddlers, Kotarou is normally quite calm and rather unflappable. This is acknowledged in-universe, as any time he does cry, other characters are quick to note that such an action is very unusual of him.
  • Nice Guy: As far as the toddlers go, Kotarou is one of the most kindhearted kids you'll ever meet. In addition to his Big Brother Worship compelling him to acts of kindness for the sake of Ryuuichi's happiness, he has also attempted to break up fights between Take and Kirin, and he (non-verbally) affirmed that he would support Saikawa when the latter was uncertain of how well he could fill in for Usaida. Kotarou is also generally the best-behaved of the toddlers and is usually an outlier when the rest of them are causing trouble.
  • Only Sane Man: Compared to the rest of the kids, he is level headed and mature for his age. He knows how to act in most situations, like getting lost, and he often settles everyone down when the motions get high among his friends.
  • The Quiet One: The least talkative of the daycare kids, usually content to nod his head or simply go "Ung".
  • Red Oni, Blue Oni: Kotarou is the calm blue oni to Taka's rowdy red oni.
  • Series Mascot: Kotarou is in almost all chapter covers of the manga, is the most prominent character in promotional material, even more-so than his brother. So far, he is also the only character to have a solo appearance at the manga covers (an extra jokes that this wasn't easy for him to do and he runs back to his brother afterward).
  • The Stoic: Kotarou emotes very little, but others can easily read him anyway. He blushes and looks saddened without really changing his expression. When he cries or smiles, it's because something big has happened.
  • Strong Family Resemblance: If episode 3's end card and Usaida's dream of him as a student is anything to go by, Kotarou will grow up to look a lot like Ryuuichi except with green hair.
  • Sweet Tooth: Kotarou's love of sweets isn't more pronounced than what is realistic for someone his age, but in the anime's end credits, while the other daycare kids have their favorite toys in their designated backgrounds, Kotarou's is made up of desserts and candies.
  • Third-Person Person: To go with his grammatically broken way of speaking, Kotarou says "Kota" in place of pronouns.
  • Why Did It Have to Be Snakes?: Like many children too little to swim, Kotarou's deathly afraid of deep water. Not even being held by Ryuuichi quells his fear.
  • You Gotta Have Blue Hair: His hair is a light tone of green.

    Taka Kamitani
"Aniki, you jerk… I love you."
Voiced by: Yuko Sanpei

"Ryuu-chan, my wish is that I can play baseball and be as cool as my brother!"

Hayato Kamitani's little brother. He loves Sentai shows and always carries around a toy sword, which he considers his greatest treasure. He and his brother have a strange but ultimately loving relationship.

  • Animal Theme Naming: His given name means "hawk" and his family name contains the kanji for "wolf". He shares the bird of prey first name with his brother, whose name means "falcon".
  • Annoying Younger Sibling: Kamitani largely views him as a little nuisance of a brother, though it doesn't help that Taka can be a Bratty Half-Pint at times.
  • Big Brother Worship: While he hides it, he really looks up to Kamitani and yearns to be like him someday, which is even a wish he makes in a chapter.
  • Bratty Half-Pint: Easily the rowdiest among the kids, and the one who mouths off to adults the most often (especially Usaida). Taka's bratty behavior makes Kamitani view him as an Annoying Younger Sibling most of the time.
  • Catchphrase: "I didn't do nothin' bad!"note  usually when he did do something bad.
  • Crazy Jealous Guy: Taka considers Kotarou his best friend and has shown a bit of possessiveness toward Kotarou as a result. For example, when Kazuma gets sick and Takuma comes to the daycare without him, Takuma holds Kotarou's hand. Taka gets jealous and pulls on Kotarou's other arm until he realizes the situation and decides to include Takuma as well.
  • A Day in the Limelight:
    • Chapter 64 has him deciding to run away from home when his mother refuses to buy him a toy, leading to him accidentally running into his father while Ryuuichi, Kamitani, and Shizuka look for him.
    • Chapter 74 focus on him and his mother, as he has gotten his first cavities and refuses to deal with it, while Shizuka thinks on how to make him go to the dentist.
  • Does Not Like Spam: Taka has to either be tricked or bribed into eating broccoli.
  • Fanboy: He's a big fan of a Sentai-themed Show Within a Show called Ranger Five. Being so young, he's convinced that superheroes are real, and he uses a photo of when he met the show's characters as evidence (not realizing that they were really just actors in costume).
  • Green-Eyed Monster:
    • About Kotarou. He considers himself Kotarou's best friend and dislikes when others try to snatch him away from him. He is also prone to holding Kotarou's hand to push him away from others.
      Taka: Kotarou is mine! You can't just kiss him!
    • He also dislikes when his brother doesn't pay enough attention to him and others try to spend too long with them. He even pushes other kids who seem too close to his brother.
    • Comes to a head in chapter 75 when he sees Kotarou and his brother making a pinkie promise and he doesn't know who to be jealous of.
  • Jerk with a Heart of Gold: He is kind of jerkish to the others kids, specially when things don't go his way, but if he realizes he has done wrong, he will try to make up for it and apologize. He also genuinely cares for everyone in the daycare, with a special mention to Kotarou, whom he considers his best friend.
  • Morality Pet: To his father. He is a hardass with everyone else and even to Kamitani he doesn't show to care all that much, but he seems to have a hidden soft spot for Taka, automatically calling for first aids when Taka trips during the Sports Festival and Kamitani reveals he sends anonymous gifts every Christmas to Taka, something he figured out a long time ago. When he learns of Kamitani and Taka's fallout over a baseball, he instantly sides with Taka and berates Kamitani.
  • Never My Fault: He has a hard time apologizing and admitting his mistakes, which is noticeable because the other kids do that easily. He will blame whoever is fighting him and it takes until his brother talks with him for him to admit his mistake.
  • Odd Friendship: Taka is the loudest, rowdiest, and rudest of the daycare kids, in stark contrast to the quiet, gentle, well-mannered Kotarou. Despite this, Taka considers Kotarou his best friend.
  • Red Oni, Blue Oni: Taka is the Red Oni to the more behaved Kotarou and Kirin's blue, being a lot more rowdy and prone to being a Bratty Half-Pint.
  • Spoiled Brat: Taka has rowdier behavior in comparison to his brother. Hebihara snarks that this is due to the lack of strict parenting, and Shizuka mentions this in Chapter 74 with Hebihara's words in her mind. She contributes Hebihara's strictness to Kamitani's good hygiene and thinks that maybe she is spoiling Taka a bit. Although, to a certain degree, Kamitani notes that, even if he were there, he'd be much more doting to Taka than what he was to him.
  • Strong Family Resemblance: He has Hebihara's face. This is more prominent in chapter 84, where a teenage Taka is shown to look like a cheerful, younger version of his father.
  • Tsundere: Mostly because he gets easily flustered or offended, he can be a boisterous and jerkish kid, but just as easily shifts towards a very sweet and caring boy when he notices someone needs it.
  • Verbal Tic: He tends to end his sentences with "jo" or "da jo" (a childish way of saying the standard masculine sentence particle zo/da zo).
  • You Gotta Have Blue Hair: He has dark blue hair which is different from his brother whose hair is fully black.

    Kirin Kumatsuka
"You can't get in the way of peopwe's works, Koutarow-chan"
Voiced by: Konomi Kohara (anime), Ayana Taketatsu (drama CD)

"Thankyou fow wooking aftew me, I'wl be a good giwl. Mummy towd me to be a good girl, I fowgot!"

Kirin is the oldest girl on the daycare. Kirin is a bit more educated than her peers and intends to study really hard. She has a fondness for her giraffe plushy that is always seen in the daycare center and is very close to her mom, something her dad finds beautiful, but is also a bit jealous of.

  • Alliterative Name: Kirin Kumatsuka.
  • Animal Theme Naming: Though her given name is written with different characters, it sounds the same as the Japanese word for giraffe (kirin)note ; she loves giraffes and is very attached to her giraffe plushie. Her family name also has the kanji for "bear".
  • Baby Talk: The most pronounced case. Because she speaks in a very polite and developed manner, a way to show that she is still a kid in her speech is by making otherwise eloquent sentences filled with childish speech impediments (such as how she pronounces "desu" as "dechu"). English translations tend to give her Elmuh Fudd Syndwome to reflect this.
  • Big Sister Instinct: As the more mature child of her daycare group, she sometimes likes to play the role of the caring big sister, especially towards fellow girl and baby Midori whom she sometimes holds and hugs. She's also willing to be Takuma and Kazuma's big sister when the twins have the same haircut as her.
  • Cute Witch:
    • She wants to become one due to believing that witches are real, and even attempts to fly on a broom during an entire chapter before being saved by Ryuuichi after she jumps from a high ledge. Though she's upset that she can't fly, the Chairman lets her down easy by telling her that it's 100 years too early for her to become a witch, which gets Kirin to stop endangering herself without shattering her fantasy.
    • In the Halloween event of chapter 72, she dresses up as one and is even given the name of "cute witch".
  • A Day in the Limelight:
    • A few chapters focus on her coping with being away from her mother whenever she has drama or other school commitments, with two of them focusing on her staying over with the Kashima brothers. The firs time this happens, she and Ryuuichi set up a play with the daycare kids for her mother.
    • Chapter 15 focus on her desire to become a witch and prove the daycare kids wrong and that witches are real.
  • Generation Xerox: She takes part in the drama club as a teenager if the anime endcard's drawing of her as a student (and Usaida's dream of her as one) is anything to go by, like her mother.
  • Girlish Pigtails: A girly toddler who sports a pair of pigtails at all times, and says that her mother does them for her. Ryuuichi has trouble doing them when she first stays with his household.
  • Girls Love Stuffed Animals: She's often seen with a stuffed giraffe when she's at the daycare, and she's very attached to it.
  • Girly Girl: Something that often causes tension in the daycare is how different are her interests to the rest of the boys. She likes to play house, but boys rarely go along with it, specially Taka. This causes her to feel isolated sometimes, up until she meets Kyouko, who befriends her and starts visiting the daycare.
  • Keigo: Her speech patterns are very polite despite how young she is, though this is offset by her childish speech impediments.
  • Parental Favoritism: Inverted and played for laughs. She is much more fond of her mother than her father and doesn't hide it. In a chapter focused on each family's daily life, his father shows that he feels a bit left out because Kirin is so clearly closer to her mom than him.
  • Shipper on Deck: In a chapter, she attempts to get Inomata and Ryuuichi together when she finds out she likes him. This is less of her shipping them together and more of an extreme overreaction to the (incorrect) notion that Inomata doesn't play with the kids at the daycare because she hates Ryuuichi and is avoiding him.
  • Strong Family Resemblance: Looks very similar to her mother, except for the shape of her eyes, which she got from her father.
  • Third-Person Person: Kirin speaks in third person, which is typical for very young children in Japan. Her aged up version in Usaida's dream also does the same.
  • Women Are Wiser: She is notably more eloquent and mature than her peers, or at least tries to be. Her speech is more developed, she's the only one to carry juice without falling over at their cafe (to be fair everyone's costumes made it really hard for them to walk), and she's the first to know how to write.
  • You Gotta Have Blue Hair: He hair is green, almost teal.

    Takuma and Kazuma Mamizuka
Takuma and Kazuma, respectively
Voiced by: Ayaka Saitou (Takuma) and Atsumi Tanezaki (Kazuma)

Two twin brothers with identical appearances but very much opposite personalities. They are always seem together and are differed by their mood: Takuma is always cheery while Kazuma is always teary.

  • Always Identical Twins: Outside of their expression, which is the way others use to differentiate them, they are completely identical. Even their parents have a hard time telling them apart when both of them are smiling or crying.
  • Animal Theme Naming: They both have the kanji for "horse" in their names, which doubles as Theme Twin Naming in their case. Their family name also has the kanji for "tanuki".
  • Big Brother Instinct: In spite of being twins, Takuma is technically the older brother; as a result, he has a bit of a protective vein for Kazuma, as showcased when he fought a cat to get Kazuma's gift back.
  • Cheerful Child: Takuma is the straightest example out of all the kids, since he's almost constantly smiling and cheerful.
  • Color Motif: Interestingly inverted. Takuma most often dresses in cold colors, usually blue, while Kazuma wears warm colors, like yellow. However, Kazuma is the melancholic one while Takuma is the warm upbeat one.
  • Coordinated Clothes: They are always wearing similar outfits but with some differences, like the first letter of their names or the color of their shirts. It is rare when they don't wear similar clothes but it does happen.
  • Cowardly Lion: Ryuuichi considers Kazuma an extremely brave kid deep down, seeing as how, no matter the risk, he will go for it once he notices that his brother can benefit from it one way or another.
  • Cry Cute: Kazuma's default expression is to be teary while still looking adorable.
  • A Day in the Limelight:
    • An extra chapter shows a day in their household where Takuma and Kazuma have a fight.
    • Chapter 46 follows them in their first errand as they go to their neighborhood store to buy milk by themselves (followed by their father).
  • The Dividual: They don't quite count as Single-Minded Twins since they have different personalities, but they're hardly seen apart and mostly always act as a single entity, with Kazuma's lines often just repeating what Takuma said with fewer words. This gets subverted on a few occasions: when they fight, when Kazuma has a cold and Takuma goes alone to the daycare and when they split because Takuma wants to go to a pool and Kazuma doesn't.
  • Funny Background Event: Both twins are seen eating food that's been dropped on the floor at daycare in the background on a few occasions.
  • Gag Haircut: Downplayed in Chapter 69 when Umi accidentally cuts their bangs too short and they love it until Taka mocks them and Kamitani attempts to take Kazuma's "wig" off.
  • Generation Xerox: A personality variant to their parents.
    • Their father, Kousuke is a shy Shrinking Violet that can be brought to tears very easily, a trait Kazuma inherited wholly.
    • Their Mother, Umi, is an always cheerful woman who rarely ever shows a face that isn't a smile, something she shares with Takuma.
  • Identical Twin ID Tag: They're identical twins and can be easily confused on that alone but there are cues to differentiating the two of them:
    • Their expressions. Takuma is always smiling and Kazuma is always teary-eyed. Once Takuma starts crying, they're harder to differentiate — in an extra chapter, it's revealed that Umi and Kousuke have difficulty of telling them apart when they are both crying or both smiling.
    • They often wear similar clothes but with different colors, with Kazuma often in warm colours and Takuma in cool colours. When they're seen at home, they're often shown having cups or shirts with the first letter of their name imprinted on them.
  • Mouthy Kid: Takuma can be, albeit without really meaning to. Since he likes to repeat what he hears, he'll loudly mimic Taka or Hayato calling people stupid.
  • Parental Title Characterization: When Kousuke is first introduced, it's shown that Takuma and Kazuma call him "Kou-kun" since Kousuke's busy schedule makes him unable to spend much time with them and they don't really see him as their father as a result. Once it registers to them that he really does love them, though, they call him "Papa" from that point on.
  • Perpetual Smiler: Even in situations where the other kids start crying, Takuma can stay cheery or at least less teary.
  • Polar Opposite Twins: Takuma is outgoing and constantly smiling, while Kazuma is shy and constantly teary-eyed.
  • Prone to Tears: Kazuma is constantly on the verge of tears, and he's prone to crying at the drop of a hat since he scares so easily. His tendency to get easily upset can be justified since he's only a toddler, though it's also meant to contrast with his Perpetual Smiler twin brother.
  • Reality Ensues: They are introduced as being distant to their father. While Kousuke believes that it's because of his crazy work schedule, it's actually because Umi showed them a thriller movie in which Kousuke played a kidnapper. Because toddlers can't differentiate television from reality, they get scared of their father. Similarly, they genuinely think their father's been brainwashed when they first watch him as the bad guy on the Justiknight show, not realizing he's just acting — however thanks to Asahi's intervention, they start to understand that actors are different from their characters.
  • Shrinking Violet: Kazuma is very withdrawn compared to Takuma, and doesn't often speak unless Takuma speaks first; even then, he'll usually just repeat what Takuma says with fewer words.
  • Third-Person Person: Kazuma will occasionally refer to himself in the third person, which isn't surprising since he's just a toddler.

    Midori Sawatari
Voiced by: Kaede Hondo

The youngest of the kids at the daycare, being just a baby. Usaida usually looks after her when he isn't sleeping.

  • Animal Theme Naming: Her family name has the kanji for "monkey" in it, and she's associated with monkeys in the anime's opening. Her given name also contains the kanji for "bird".
  • The Baby of the Bunch: Literally, as she's the only infant amongst the toddler-dominated daycare.
  • Baby See, Baby Do: As of Chapter 14, Midori copies Usaida's fist-to-palm "I've got it!" gesture, right down to the sound effect.
  • Black Bead Eyes: Notably the only one of the kids to be drawn with round black eyes, which tend to be commented on by other characters. Even as a teacher in Usaida's dream, one simplified panel of her still uses these eyes.
  • Blush Stickers: Downplayed but her cheeks constantly rosy.
  • Brainy Baby: Sometimes for comedy, Midori will show more intelligence than is average for a child her age. When the whole daycare room was preoccupied with Tsugumi, Midori suddenly wet her diaper. Her sneaky expression makes it apparent this was an intentional ploy to get attention.
  • Cheerful Child: She's constantly smiling and happy, along with being something of a Genki Girl.
  • The Diaper Change: Being the only infant in the cast, she's often the source of the diaper change gag. One chapter implies that she's aware of this and invokes it to get people's attention.
  • Genki Girl: For a baby, she's very cheerful and energetic. Even in Usaida's dream, Midori as a teacher is still bubbly and full of energy, something Usaida notes.
  • Hair Decorations: Her hair bobbles are used to tie up what little hair she has, making her look cute. The anime's endcard of her as a Morinomiya Academy student still keeps the bobbles for her ponytail.
  • Living Prop: Since she's unable to communicate with others outside of baby noises, she usually serves this role unless a chapter is related to her or she's part of a joke.
  • The Unintelligible: Can't speak yet so she can only babble. Her first and only word in the series is Usaida's name ("Udda!"/"Usa!") — though no one can seem to agree if she's really trying to say his name or if it's typical baby gibberish.


The Morinomiya family

    Chairman Youko Morinomiya
Voiced by: Tomoko Miyadera

The chairman of Morinomiya Academy and the adoptive guardian of Ryuuichi and Kotarou.

  • Animal Theme Naming: Her given name has the kanji for "sheep", and her large, poofy afro makes her look like one.
  • Berserk Button: Half-assing things or not being sufficiently responsible are things that quickly get her angry. Also quick to anger if her hair is called fluffy/shaggy like Kotarou does.
  • Broken Bird: She's become very bitter after losing her son and his wife.
  • Cool Old Lady: Though she tries to hide it, the elderly chairwoman is a reasonable and caring parental figure for the Kashima brothers and she's also firm yet wise. She gives Ryuuichi life advice when necessary and can easily get on the same wavelength as the toddlers if she wants to teach/tell them something.
  • Everyone Has Standards: She might work everyone she knows to the bone, however, she has an extremely caring vein, and is very rigid on her rule that sick people should take care of themselves. When Ryuuichi is sick, she makes him lay and rest, not even waking him up.
  • Funny Afro: Has a big, bushy afro reminiscent of a sheep. Kotarou thinks it's fluffy.
  • I Was Quite a Looker: Chairman Morinomiya, who is depicted as an exaggerated caricature of a cranky old lady in the present, was once an adorable little girl.
  • Jerk with a Heart of Gold: She's harsh and abrasive but she does care. She just hardly shows it and, when she does, she plays it off as something else.
  • Outliving One's Offspring: She lost her son (and his wife) in the plane crash.
  • Reasonable Authority Figure: The Chairwoman seems really tough at first, but it turns out that she genuinely cares for the children and Ryuuichi. She takes it upon herself to take care of him when he gets sick, and even lets Kotarou help.
  • Replacement Goldfish: Defied. She warns the Kashima brothers that she hasn't called them to replace her son, and makes it clear how she doesn't intend to replace their parents, they however do build a new family with each other without necessarily using each other as replacement for their lost ones, but in the principle that even when those who love us are gone, it doesn't mean we are alone.
  • Tough Love: Most of everything she does boils down to this. Case in point, her way of teaching Taka a lesson in respecting other people's property was making him think she was going to smash his beloved toy sword.
  • You Are Not Alone: Gives this speech at the end of the first chapter/episode when she finally sees Ryuuichi mourn for his parents, saying that even if their loved ones are gone it does't mean they're alone. Despite her gruffy nature, it's all but said she took in the siblings so that they'll still have a family even if not blood-related.

    Keigo Saikawa
"I promise to protect Koutarou-sama even if it costs my life"
Voiced by: Daisuke Ono

I… was not aware of that. To the chairwoman, Ryuuichi-sama and Kotarou-sama, and… even I am considered family.

The chairman's assistant and butler. He takes care of her house and is known for excelling at every house task.

  • Affectionate Nickname: Kotarou calls him Sai-chan/Sacchan.
  • Ambiguously Human: Played for Laughs with Saikawa, a stoic, hypercompetent butler/secretary/whatever who has the tendency to pop out of nowhere. When a discussion about his house comes up, Kamitani expects him to live in a coffin like a vampire, while Usaida expects him to come from a manufacturing company. In one omake, he agrees to go for a drink with Usaida, and is mistaken as a mannequin by the store patrons because he didn't move at all.
  • Butlerspace: Like any good butler, he somehow has the ability to pop into a scene out of nowhere.
  • Cold Ham: He is capable of chewing scenery, mostly without the need of making any expression during it.
  • The Comically Serious:
    • He always harbours a serious and emotionless expression, even when it's very clear by his speech that he is emoting something — this results in several funny moments.
    Ryuuichi: [while leaving to go to a movie] Okay, please take care of him, Saikawa-san.
    Saikawa: [serious face] Understood. I promise to protect Kotarou-sama, even if it costs me my life.
    Ryuuichi: [surprised] Ah, no, I don't think you need to go that far...
    • In chapter 72, even when he catches a cold and ends up passing out from exhaustion, his expression still doesn't budge an inch.
  • Deadpan Snarker: Saikawa often snarks while maintaining his stoic and polite demeanour, for example in this lovely bit during a phonecall:
    Taka: *breathes heavily into the phone, having unexpected Saikawa to pick up, rather than Ryuuichi*
    Kamitani: Talk, you idiot! State who you are! What are you, a pervert? . . . *takes the phone* Ah, I'm sorry. It's me.
    Saikawa: If you're asking about my underwear, it's black today.
  • Eyes Always Closed: His eyes are are rarely opened, which contributes to his "butler-like" appearance.
  • Extreme Doormat: Despite being skilled in almost everything, Saikawa's sole purpose of existence is to dutifully serve the chairwoman and, by extension, the Kashima siblings. When he's assigned to take care of the toddlers in place of Usaida, he actually bows down to the kids because "dealing with children" is one of the few things he's not really an expert at.
  • Family of Choice: He is considered to be part of the family, though he only realizes that once the chairwoman forces him to rest up after he catches a cold.
  • Mysterious Past: Due to his Ambiguously Human traits, other characters would sometimes wonder about his personal life outside of being the chairwoman's butler. What little he reveals about his past (he mentions having a grandmother who cooks him French dishes, implying that he has some French ancestry) only makes him more mysterious.
  • The Stoic: Outside of surprise, he rarely shows any other emotion. Even then, he is still only very rarely surprised and it not always shows through.
  • Supreme Chef: Capable of making any dish. He takes pride in providing his family high quality meals and making sure they're enjoying them. For example, in Chapter 58 he attempts to create a dish with vegetables so delicious that Taka will eat them; despite the struggles, he succeeds by making veggie burgers and giving them to Taka without telling him about it (he's mad at first but begrudgingly asks for seconds). He's easily offended when it looks like people dislike/reject his meals and it's a Running Gag in such cases that he'll comment on going back to culinary school while packing up to leave.

    Youichi Morinomiya 
Voiced by: Tomoko Miyadera

The chairman's son and only child. He was also a teacher at his mother's school. He, along with his wife, died in the same plane crash as the Kashima brothers' parents, which is what lead to his mother taking in the brothers.

  • Brutal Honesty: Casually described Usaida as someone "who looks incapable at a glance" to Kamitani when introducing them to each other.
  • Death by Origin Story: He and his wife died before the series begins.
  • Mentor Archetype: Acted as a mentor to Usaida after recruiting him for the school's daycare, helping him prepare for the childcare exams and get back into leading a more productive life. Usaida still secretly keeps the teaching guidebook he wrote, using it for his future plans of becoming a teacher.
  • Nice Guy: Flashbacks show that he was helpful and kind to others, whether it be people at school like Kamitani and Yukari or his own butler Saikawa. Notably, he got Usaida out of his slump by helping him become the academy's daycare worker, recognising that Usaida was always helping others as a student. His kind actions is what inspired Usaida to look into teaching himself.
  • Plot-Triggering Death: His mother would had unlikely taken the Kashima brothers and kickstart their daycare adventures if he and his wife had died in a separate incident from the brothers' parents (or not died at all).
  • Posthumous Character: His death from the plane crash occurs shortly before the story begins.
  • Ugly Guy, Hot Wife: From the little we see of his wife, she appeared to be more attractive and aging better than her husband who looked more unfit and had a saggy face.


    Maria Inomata
"I don't intend to do something so irresponsible as going back after I was asked to do something."
Voiced by: Satomi Akesaka

"'Sorry' won't cut it!"

A high achieving member of the advanced class widely known for being smart beyond her age and keeping the #1 spot in grades for a long time. She is a stickler for the school's rules and berates people who break them.

Tends to react very harshly to everything, but she hides a soft and lonely interior.

  • A-Cup Angst: When the kids meet Ushimaru for the first time, several of them note her large bust reminds them of their mothers'; Inomata holds her chest and comments how the kids never had the same interest in her, depressed.
  • Adaptation Expansion: Due to a lot of story shuffling, the anime includes several stories that star her, giving her much more screentime than what she would have if the series was adapted normally. Her screentime nearly rivals Kamitani, who is a lead character.
  • Adorkable: She is extremely easy to embarrass, and her overreaction to even the smallest questions as accusations causes people to think that she is cute when she gets like this.
  • Affectionate Nickname: Called "Maria-chan" by Ushimaru. The kids in the daycare tend to call her "onee-chan" or "Ino-nee-chan".
  • Animal Theme Naming: Her family name contains the kanji for "boar".
  • Berserk Button: She loathes people who half-ass things and don't work hard in their studies or respective duties. The initial dislike towards Ryuuichi comes from the idea that he isn't taking his duties in the daycare or his studies seriously enough, despite the fact that the kids followed him.
  • Defrosting Ice Queen: Through Ryuuichi and the kids, she starts to mellow out and make friends with them.
  • Face of a Thug: Played With. She has the face of an average teenage girl, however, her scary expression, no nonsense attitude and serious tone makes people scared of her all the same. This is enough to even make the kids ask her to be an oni in their play.
  • Friendless Background: She was never any good in making friends and would often react with anger at the slightest note of someone pitying her; as a result, she pushed everyone away and focused on her studies. After a while, she starts opening up to people and making friends with others and the kids.
  • Hidden Depths: She believes all she is good for is studying, which directly affects the fact that she doesn't have friends, as she believes to simply not being wired to be good with people.
  • No Indoor Voice: Accidentally. She is capable of speaking calmly when the situation calls for it, but she will easily get angered or embarrassed and start screaming.
  • No Social Skills: She is very awkward and easily embarrassed, that's from where her harsh attitude comes from. She is still learning how to interact better with others and how to not burst attempting to communicate simple things. In chapter 61, she briefly mentions she never had any phone numbers in her phone besides her parents up until then.
  • Not So Above It All: Inomata, who often states how childish some action is or how its against the rules, usually relents later in the chapter. In the case of childish things, she is either "forced" to do it by simply being asked or by tries it out in secret, such as pretending to ride a broom like a witch when she thinks no one is looking.
  • Principles Zealot: Downplayed. Whenever she makes an appearance, expect someone to be scolded for acting unruly in any way, with Inomara pointing out what infractions they're committing. She'd even scold others just for standing on the hallway or right in front of the door. It's why she has a reputation of being a wet blanket.
  • Single Woman Seeks Good Man: She slowly but continuously falls for Ryuuichi's kind attitude and aptitude when dealing with little kids.
  • Tsundere: She is angry, harsh and strong headed, but she can quickly become docile and sweet, especially with the kids and Ushimaru.
  • When She Smiles: When she laughs in chapter 61, the kids, Ryuuichi, and Ushimaru are briefly amazed and even start smiling as well.
  • The Woobie: In-universe. Her Friendless Background and difficulty in stating her own feelings and opening up causes people to pity her and attempt to help her join their group. Even the kids pity her loneliness.

    Hiroyuki Inui
"Nothing matters in love, not even age."

"Oh no. My angel, no, my goddess is here!"

Voiced by: Yoshimasa Hosoya

A second year in Morinomiya Academy. A boy with several love woes and a tendency to fall in love.

  • Animal Theme Naming: His family name contains the kanji for "dog".
  • Ambiguously Bi: He's initially in love with Yukari and tries to pursue her before finding out that her husband's actually away for work and not dead. He then falls in love with a cute girl he sees at the daycare during the school festival — the thing is, that girl is actually Ryuuichi in a wig (at Yayoi's insistence, to avoid having Kirin's father have a stroke at seeing boys around his precious little girl). Inui eventually finds out and is embarrassed; later on, however, it's implied that he's still attracted to Ryuuichi.
  • Big Brother Instinct: Though not at the same level as Ryuuichi, it's shown that even though they bicker a lot he truly cares for his little sister, Mika, and tries to protect and cheer her up. He also starts to warm up to the daycare kids and develops a protective instinct towards Kotarou.
  • Butt-Monkey: A lot doesn't go well for him, whether it be his romance woes or the kids and fellow students looking down on him.
  • Has a Type: He has stated that he likes the cute, fluffy type girls, which is true with his crush on Yukari and crossdressing Ryuuichi.
  • Love Hurts: Oh boy. The guy at first is in love with his teacher (a married woman with a child mind you) and then with a guy who cross dressed. Despite these conditions, he still tries to woo them.
  • Oblivious to Love: Ironically, he is unaware of Nekota's slight crush on him.
  • Precocious Crush: Initially has a crush on Yukari, who is married and a teacher much older than him.
  • Secret Identity: Twice Inui has saved Kotarou while wearing a paper bag on his head in some way when Kotarou was alone, to the point of where Kotarou put a similar paper bag on his head to copy his hero.
  • Unknown Rival: Considers himself a rival to Yutaka for Yukari's love, but the man barely even knows him.

    Yuki Ushimaru
"Well, maybe I do like him a little."

Voiced by: Kaede Hondo

She is a classmate of Ryuuichi and Kamitani.

  • Affectionate Nickname: Called Yuki-chan by Inomata.
  • Animal Theme Naming: Her family name contains the kanji for "cow".
  • Child Hater: Not in a villainous way, but when she goes to the daycare for the first time, she tells Ryuuichi that she is not good with kids due to her being harassed by them in the past. She grows out of it later on, as she spends more time with them.
  • Clingy Jealous Girl: Inverted. While she's initially nervous about the idea of Ryuuichi being closer to Inomata than to her, she ends up finding herself connecting with Inomata specifically on the basis of their shared hopeless crushes on Ryuuichi and forming a friendship with her.
  • D-Cup Distress: She's extremely uncomfortable with the children calling attention to how large her breasts are, although it may be more because of the fact that they try to grab her breasts. In front of Ryuuichi.
  • Dude Magnet: She's popular among her male classmates, but Ushimaru doesn't seem to notice them, and only has eyes for Ryuuichi.
  • Entertainingly Wrong: She believes that Ryuuichi and Inomata are dating when she finds him giving her chocolate. It's just a thank you gift for her for helping around the daycare, but Ushimaru has no reason to think it's like that.
  • Friendly Rivalry: She's initially suspicious and jealous of Inomata's relationship with Ryuuichi, but eventually gets along with her and becomes one of her first friends.
  • Gag Boobs: Most of the kids happily point out Ushimaru's ample bust, unaware that it causes her distress.
  • Nice Girl: Very kind and generous.
  • Shrinking Violet: Every single implication that she is interested in Ryuuichi, as well as her interactions with him, cause her to become a blushing mess. Interestingly enough, she is nowhere near this shy when around other people (hilarious shown when she runs away flustered when catching Ryuuichi changing out of his shirt but being perfectly fine with guys in the tennis club training topless).

    Tomoya Yagi
"You just seem so chubby and so round!"

Voiced by: Toshiyuki Someya

"But occasionally, coming over to pinch the kids cheeks, isn't that bad."

Inomata's classmate who really adores kids.

  • Animal Theme Naming: His family name means "goat".
  • Balanced Harem: As the popular handsome guy in the schol Yagi is often surrounded by a group of girls as background characters.
  • Bishōnen: One of the most desired guys in school due to his astounding good looks.
  • Because You Were Nice to Me: The primary reason that Tomoya is friends with Chuukichi. When Chuukichi brought Tomoya over to his house Tomoya became grateful as Tomoya says in Chapter 77 "Your way of living is really cool!" as Tomoya had no real friends before meeting Chuukichi and his family
  • Chick Magnet: The most popular guy in school.
  • Childhood Friends: Been friends with Chuukichi since childhood, with a few chapters focusing on how they got acquainted.
  • Cuteness Proximity: He likes kids a lot because of their cuteness, which often leads to him breaking out into rather creepy and misleading nosebleeds.
  • A Day in the Limelight: Chapter 37 focus on him and his birthday. It tells his backstory on how he came to adore kids so much and the start of his friendship with Chuukichi.
  • Friend to All Children: He genuinely wants to be this, but his constant nosebleeds whenever he interacts with kids tend to give people the wrong impression.
  • Mistaken for Pedophile: His nosebleeds can give the wrong impression on his liking for kids.
  • Siblings Wanted: At the end of Chapter 37, he asks if he can have a younger sibling, much to the shock of his parents and his older sister.
  • Perpetual Smiler: Almost always seem with a grin in his face.

    Chuukichi Nezu
"Stop it, pervert."

Voiced by: Motohiro Ota

Inomata's classmate who is quiet but reliable.

  • The Ace: Chuukichi is known for being able to do basically anything. He's kept the second academic ranking in his grade for a long time at school, despite working and helping around the house all the time. Every character is impressed by his dedication and responsibility. Also, chapter 61 shows that he is capable of making a slide out of snow.
  • Animal Theme Naming: His family name means "mouse".
  • Big Brother Instinct: To all his younger siblings. This tends to crop up the most around Tomoya and in one chapter Chuukichi became seriously pissed when he thought Tomoya did something to make Kichi and Shuekichi cry.
  • Bishōnen: Not noticeable at first glance, but he's got a handsome face underneath those bangs.
  • Blinding Bangs: A trait he shares with most of his family members.
  • Chick Magnet: Not to the same extent as Tomoya, but he's noted to be quite popular as well.
  • Childhood Friends: With Tomoya. Their friendship apparently started when Tomoya was alone for his birthday and Chuukichi found him crying about it. A later chapter also reveals that another reason for their friendship was because Tomoya was the only one in his class who didn't judge him for coming from a poor family.
  • Cloud Cuckoolanders Minder: He's the one that keeps Tomoya's antics in check.
  • Family Theme Naming: All of his male siblings share "Kichi" which means luck.
  • Massive Numbered Siblings: He has five siblings, four brothers and one sister. He is the second oldest child of the family.
  • The Reliable One: The most mature and level-headed out of all the Nezu siblings. In times of trouble, he's often the one to keep calm and takes charge to get the situation under control as well as solving the issue at hand as quickly and efficiently as possible.
  • Straight Man: The more reasonable guy who constantly has to keep Yagi, who is often a bit too excited over kids, in check.
  • Unwitting Instigator of Doom: Chapter 37 shows that he was the accidental cause of Yagi's love for children. He brought him to his house on his birthday, and the sight of Kichi and Suekichi as toddlers gave Yagi his first nosebleed.
  • Vitriolic Best Buds: One-sided version with Tomoya. He often expresses annoyance at Tomoya's behaviour around children, openly tells him to stay away from his younger siblings and overall acts more like his keeper than his friend. He even apparently has regular moments where he outright wonders why he's even friends with someone like him. Yet despite this, he knows that Tomoya is a good person at heart and still sticks by him regardless.

Inui-senpai's classmate who has a slight crush on him. Has a cousin named Tamako.
  • Animal Theme Naming: Nekota has the kanji for cat.
  • Gyaru Girl: She follows the gyaru girl styling, wearing heavy makeup (including massive eyelashes) and curling her hair.
  • Hopeless Suitor: Has a slight crush on Inui that probably won't be reciprocated, but she doesn't seem to mind.
  • Tsundere: Nekota snaps at Inui whenever he says something sexist or tells her she's not a cute girl.

The Morinomiya students/daycare's families

    The Kashima Parents
"Ryuuichi, Kotarou, we're home!"
Ryuuichi and Kotarou's parents who passed away in a plane crash. The father worked with IT sales, and the mother was a translator/interpreter.
  • Death by Origin Story: They died before the story even begins.
  • Deceased Parents Are the Best: Their habit of travelling and leaving the sons behind aside, Ryuuichi has fond memories of his late parents who are always smiling and being affectionate with him in his flashbacks. Even Kotarou vaguely remembers them in a good light.
  • The Faceless: Their faces have yet to be revealed, with their eyes being closed whenever they're not being obscured.
  • Parental Abandonment: Not by choice. They died in a plane crash, leaving their sons alone.
  • Plot-Triggering Death: Their deaths lead to their sons moving in with the Morinomiya Academy chairwoman who has the older son become the daycare's babysitter in exchange, kickstarting the story.
  • Posthumous Character: The plane crash that caused their death occurs just before the story begins.
  • Unnamed Parent: Neither parents have been given names yet.

    Taizou Hebihara and Shizuka Kamitani
"Honestly, I don't know who you take after."
"Next time, if you have any personal matters, please consult me after work hours as I may get distracted."

Hayato and Taka Kamitani's parents. Shizuka is the middle school science teacher while Taizou is the high school chemistry teacher. Divorced prior to Taka's birth, meaning the younger son is unaware he even has a father.

  • Adaptational Early Appearance: Shizuka makes her debut in the manga in Chapter 9, but appears in the very first episode of the anime when Kamitani drops Taka off at her office.
  • Adapted Out: Taizou Hebihara only gets a name reference in episode 5b of the anime. The story that was a precursor to his debut chapter in the manga leaves out Kashima's conversation with Kamitani (where he asks about his father) in the anime.
  • A Day in the Limelight: Chapter 89 focuses on him trying to give a shaved ice machine to the babysitter's club.
  • Amicable Exes: Although it's unclear how they get along at work, the two exes attempt to remain civil with each other in their personal lives albeit with mixed results. On one hand, they still have fond/nostalgic opinions of each other; and they'll at least contact each other when family's involved, and Shizuka's not against the idea of either of her sons interacting with their otherwise absent father. On the other hand, they have comical instances of getting on each other's nerves (complete with Lightning Glares), especially if their parenting (or lack thereof) is involved.
  • Animal Theme Naming: Shizuka's family name contains the kanji for "wolf" while Taizou's contains the kanji for "snake".
  • Chekhov's Gunman: Hebihara is mentioned in chapter 14 as the mean, overworking, high-school chemistry teacher. Chapter 25 reveals him as Kamitani's father, and also reveals his face.
  • Disappeared Dad: Both of the Kamitani siblings are estranged from their father ever since their parents divorced. Though emotionally distant, they are still physically close, since their father is one of the teachers in the school. Hebihara treats his son like other students and doesn't allow him to call him dad during work hours, and he (initially) avoids contact with Taka who is oblivious.
  • Hidden Heart of Gold: Which is what makes Shizuka fall for Hebihara. A flashback shows that one of their first meaningful interactions was when He nursed her when she passed out due to overworking and offered her his lunch despite the fact he wouldn't have anything to eat until the end of his work hours. Hebihara also has a huge soft spot for their toddler son, Taka, despite the fact he hides it with vigor.
  • Lightning Glare: They exchange glares intense enough to induce lightning for stylistic purposes when they start ragging on each other for how they do (or don't) parent Taka.
  • Stern Teacher: Hebihara is extremely strict and overworking, even forcing some students to work through the interval if their work wasn't up to his standards, he has somewhat of a infamy in school because of that.
  • Sweet Tooth: Hebihara apparently likes eating tamago (sweet omelet) a lot, and Shizuka teases to Ryuuichi that he has a sweet tooth which Taka inherited.
  • Teacher/Student Romance: Shizuka was Hebihara's student when they first met; it's not clear however, whether they started dating when they were still in that position.
  • Visit by Divorced Dad: Taizou still interacts with his children once in a while, though Taka is still unaware he is his father.
  • Working with the Ex: They're both teaching in the same school, but it's yet to show how they interact in a professional environment. It's also unclear whether their former relationship was still in place when they began working at the school together and whether it's common knowledge there (at least among students), seeing how fellow classmates aren't aware that Hebihara is Kamitani's father.

    Yayoi and Satoru Kumatsuka
The favoritism is quite obvious.

Kirin's parents. Yayoi is the Head of the Drama Department while Satoru is a freelance photographer.

  • All Men Are Perverts: Satoru believes that any male that is not himself who is associated with his daughter is a beast with ulterior motives. It doesn't help that he often says to girls, "If I were x years younger, I would ask for your hand."
  • Beauty Mark: Yayoi has one near her left eye.
  • Creepy Good: Yayoi is an Eerie Pale-Skinned Brunette with Creepy Shadowed Undereyes and is once seen dressed up as a Stringy-Haired Ghost Girl, but she's not a bad person at all and loves her daughter Kirin very much.
  • Creepy Shadowed Undereyes: Yayoi's often shown with dark eye circles, contributing to her creepy look.
  • Eerie Pale-Skinned Brunette: Yayoi is a tall pale woman with a creepy attitude and long dark hair.
  • Get a Hold of Yourself, Man!: In one extra chapter, Satoru goes crazy thinking of the possibility that his daughter is dating one of the childcare boys, leading to Yayoi calming him down with a slap on the face so they can talk normally.
  • Good Parents: They love Kirin very much even if they don't appear together often. Emphasised when Yayoi has to leave Kirin with the Kashimas for drama club work and it's made clear she doesn't enjoy leaving her — in one chapter, they make an exchange diary so her daughter won't be lonely.
  • Ham and Deadpan Duo: Satoru is very over-the-top in his behaviour, whether it be singing praises to his family or making threats the moment a boy interacts with his daughter; meanwhile, Yayoi is very calm and does not express much emotion.
  • Hypocritical Humor: Satoru claims all males, other than himself, are beasts, yet nothing stops him from flirting with women (or boys who look close enough to fool him when crossdressing), presumably younger than his wife.
  • Large Ham: To say Satoru loves Kirin and wants to protect her would be an understatement. Satoru immediately starts taking pictures of his daughter as a carrot in his debut, and when Kirin says she doesn't like when Satoru bullies others he is ready to jump out of the window (of the first floor) of the daycare.
  • Love at First Sight: A bonus chapter shows that Satoru fell in love with Yayoi when they first met; though, it was shown through an aloof facade which Satoru states is a dark part of his past.
  • Morton's Fork: Consoling Satoru is never an easy task. When Taka says he doesn't like Kirin, Satoru says, "How could you not like Kirin?!" When the other toddlers at the daycare say they like Kirin, Satoru accuses them of being beasts. When Satoru cries about losing Kirin to some guy through marriage, consoling him saying Kirin could end up not getting married has him say she most certainly will.
  • Overprotective Dad: Satoru goes berserk whenever he thinks boys are interested in his daughter. This is taken to a comedic extreme due to the fact said boys are, you know, toddlers. Yayoi has enough foresight to ask the male babysitters to dress up as girls, but Usaida's disguise isn't enough to fool him, prompting him to question the motives of the male babysitters and accuse the young boys of being "beasts" that are after his daughter.
  • Training from Hell: Played for Laughs when Kashima checks up on the usually calm Yayoi the first time she leaves Kirin with him to focus on her drama club, and she's angrily yelling at her students to be more passionate and that she won't let them sleep until they capture their roles. Kashima is rather disturbed, and Usaida lampshades beforehand that Kashima is brave for attempting to talk to Yayoi during drama club boot camp.
  • Tsundere: Satorou acted like this towards Yayoi when they first met, pretending to not like her acting only for her to catch him in all her performances and applauding her in the last one (which makes him stop and look away in embarrassment when she smiles at him in acknowledgement). This is a stark contrast to how he treats her now — if anything, the tables may have been reversed, with Yayoi giving him the aloof treatment and not going out of her way to reciprocate his hammy affections but still showing her love now and then.
  • Unwitting Instigator of Doom: As Yayoi admits, a lot of the trouble with Inui developing a crush on "Inomata" is because she made Ryuuichi crossdress the first time.

    Umi and Kousuke Mamizuka
The actor and the women of physical activity, demonstrating the image of sadness and happiness.
Voiced by: Ayaka Saitou (Umi) and Satoshi Hino (Kousuke)
Takuma and Kazuma's parents. Umi is a PE teacher in Morinomiya Academy while Kousuke is an actor.
  • Biseinen: One can't deny the good looks and slender body of Kousuke, who is in his late 20s, which is probably the main reason why fangirls flock to him.
  • Butt-Monkey: Outside of acting, Kousuke has been called useless and a crybaby. A Running Gag is that Takuma and Kazuma prefer being around their mother more than they prefer being around him, or they don't think he's cool unlike his characters.
  • Chick Magnet: Kousuke is an extremely popular actor at the moment, and his presence will call for every girl in close range.
  • Clingy Jealous Girl: Subverted when Kousuke thinks Umi is crying while watching his kiss scene in a movie because she's jealous and pauses it, only for her to unpause it and tell him off for for interrupting her at the most important part (and even makes him watch it with her). She clearly states she's fine with him kissing other women as a part of work but also off-handedly mentions she'll kill him if he does it in private.
  • Dawson Casting: In-Universe, Kousuke gets cast as a high school student in a drama. Usaida makes fun of him to no end since Kousuke is well in his late 20s. invoked
  • A Day in the Limelight: Chapter 88 focuses dominantly on Kousuke and the twins fighting over stuff and Kotarou.
  • Eyes Always Shut: Umi, which accentuates her wide smile.
  • Fangirl: Umi has all of Kousuke's DVDs at home, and watches them very often, sometimes with their children as well. Kousuke is very thankful for the support. She often praises how cool he looks in his movies. Chapter 88 has her taking the leftover Buido (the villain Kousuke played) figure when her sons move on to Justi-knight.
  • Good Parents: They love their sons very much, with Kousuke in particular trying to spend time with them whenever he has breaks.
  • High-School Sweethearts: The two first met in high school, and it was Love at First Sight at least on Kousuke's side. It was his determination to become confident enough to confess to her that lead to his career as an actor.
  • Mistaken for Pedophile: In his debut appearance, Kousuke wears a mask, sunglasses and a hat while visiting his kids. Because of this, Ryuuichi and Kamitani mistake him for a pedophile, though he's really just disguising himself so he won't get mobbed by fans.
  • Opposites Attract: Umi is an upbeat and cheery woman who is in a loving relationship with the Prone to Tears Kousuke.
  • Perpetual Smiler: Umi is usually carefree and bubbly, and maintains a smile in her face at all times.
  • Prone to Tears: Kousuke gets upset and stressed easily. Kazuma clearly takes after him in this regard.
  • So My Kids Can Watch: In-Universe, Kousuke often tries to stick to acting stints that are child-friendly as he feels embarrassed when he learns Umi and his sons watched a movie where he played a kidnapper. He also feels dreadful when dealing with the aftermath of doing a commercial that said to "Kiss the ones you like" and when he plays a Hero Killer role in a Tokusatsu show the toddlers watch.

    Yukari and Yutaka Sawatari
Very much in love, even when they're often far apart.

Midori's parents. Yukari is a secretary of the school while Yutaka is an archaeologist.

  • Date Peepers: One chapter has Yukari curious about Usaida's love life and following him around with Ryuuichi to figure out if he has a girlfriend and/or what kinds of girls he's into.
  • Flat Character: Yukari does not have as much screen time and actions compared to the other mothers (especially in the anime where few of her focus stories are adapted); and Yutaka, while having a big presence, does not appear often due to his work and mostly falls into the background.
  • The Faceless: Yutaka does not get his face revealed until much later in the story, appearing in almost all chapters with a large beard hiding his face.
  • Just the Way You Are: Yukari assures Yutaka no matter what he looks like after shaving that he will beautiful to her and vice versa in an extra chapter.
  • Papa Wolf: Yutaka gives the subtle hint to Satoru that he's not fond of strangers holding his daughter, especially after hearing the latter's rant about how he wants to watch his own daughter, Kirin, work at the school festival and meet high school girls.
  • Stepford Smiler: The pregnant Yukari tried to hide how unwell she was feeling by being cheerful and joking a lot when Usaida accompanied her to parenting class. He noticed, however, and excused her out of class so she could throw up and feel better.
  • Troll: Yukari in chapter 40's flashback was not above joking about her water breaking with Usaida in order to break the tension between the two.

     The Nezu Family 
Chuukichi's family consisting of his father, mother, older brother (Daikichi), three younger brothers (Shoukichi and twins Suekichi and Kichi) and younger sister (Kyouko).
  • Always Identical Twins: With the Nezu twins, it's hard to tell due to their similar hairstyles, but their personalities are different with Suekichi being a bit more hot-blooded compared to Kichi.
  • Animal Theme Naming: The family name means mouse and like mice, they have a rather large family.
  • Blinding Bangs: Only the mother, the twins and Kyouko have hair that hide their eye(s). Daikichi and Shoukichi do not.
  • Big Brother Instinct: The twins are rather protective of their younger sister and any of the toddlers whenever Tomoya is around. Of course, still being children themselves, they usually just end up diverting his attention towards them instead.
  • Day in the Limelight: The twins have some chapters about themselves while Kyouko gets two chapters about herself.
  • Family Theme Naming: The male siblings all have Kichi in their names.
  • Girlish Pigtails: Kyouko wears her hairs in pigtails, which further emphasise how girly she is. They also serve as a way to tell her apart from her brothers as the only girl.
  • The Klutz: The oldest brother, Daikichi, happens to be this. Every time he makes an appearance it typically involves him sheepishly apologising for breaking something. It's bad enough that, during his highschool years, his family regularly had to replace school equipment that he accidentally damaged.
  • Innocently Insensitive: All four brothers, when they overhear Kyouko asking Chuukichi whether she could become an idol, laugh and say she's neither cute enough nor talented enough to ever make it.
  • Intergenerational Friendship: Kyouko, a first grader, is good friends with the toddler Kirin since they are the only girls in their respective groups (not including Midori who's too young) who don't enjoy doing "non-masculine" activities with them.
  • Massive Numbered Siblings: The family consists of six children.
  • Outnumbered Sibling: Kyouko is the only female sibling in the family.
  • She Cleans Up Nicely: Despite fearing she's too plain, Kyouko looks amazing with a new hairstyle and dressed in one of Yuki's childhood idol costumes in Chapter 80.
  • Strong Family Resemblance: All of them look extremely similar to the point Kamitani calls them clones. Even Kyouko, the only daughter, looks a lot like her brothers aside from having pigtails.

     Inui Family 
Inui's family consisting of his younger sister, Mika, and his parents.
  • Cordon Bleugh Chef: Mika is an awful cook, which worries her brother enough that he goes out of his way to eat the lunch she's made so no one else will suffer.
  • Day in the Limelight: Mika gets two chapters dedicated to herself, mostly related to her crush on Kamitani.
  • Fangirl: The mother is a fangirl of an idol. Mika is a fangirl of Kamitani.
  • Hopeless Suitor: Minus the father, having crushes on people they most definitely will not end up with runs in the Inui family.
  • Precocious Crush: Middle school student Mika has a crush on the high school student Kamitani.

Kamitani and Taka's baby cousin and Shizuka's nephew. The Kamitani family takes care of him for a day when his parents are down with the flu. Appears in Chapter 31.

Nekota's relative who visits the daycare for a day. She makes her appearance in chapter 65.
  • Animal Eyes: Her most defining feature are her cat-like eyes. She uses these to stare at people.
  • Animal Theme Naming: Ironically, she does not have an animal name.
  • Baby Talk: She is still figuring out words and only says one phrase ("Uunjajoba!") that sounds ominous.
  • Because You Were Nice to Me: Kotarou is the only one not creeped out by her and is the first person to welcome her with a remotely friendly attitude, which leads to her growing possessive of him.
  • Clingy Jealous Girl: She quickly latches onto Kotarou and vaguely expresses hostility to anyone who comes close to him, including Ryuuichi.
  • Creepy Child: Comes off as a creepy child due to her intimidating cat eyes and unfriendly personality, which disturbs everyone but Kotarou. When she's shy, she crawls under the table where only her eyes are visible. The one word she can say in her Baby Talk is somewhat recognizable as threatening, and she directs it at anyone she doesn't like.
  • Meaningful Name: Her name is a variant of a common cat's name used in Japan (Tama).
  • Puppy Love: She develops a crush on fellow toddler Kotarou.


     Asahi Kisakata 
An actor and Kousuke's co-star in a show. Plays the main character "Justi-Knight", which is the kids' favourite show. He has great respect for Kousuke and calls him "Kou-san".
  • Biseinen: A slender man and very handsome, befitting for a celebrity.
  • Hero with an F in Good: He tries to be a hero outside of acting in front of the toddlers, but in someway or another he screws up.
  • Nice Guy: His attempts to save Kousuke face for the children are admirable, and he respects him very much. He's also friendly with the children, eager to accompany them in activities and let's them have a proper goodbye with his colleague's dog they come to love.


How well does it match the trope?
