Rentarou's Family

The main group consisting of series protagonist Rentarou Aijou and his fated 100 Girlfriends. During a Bouquet Toss challenge he christens the group as "Rentarou's Family", which sticks as something of an official name for them from that point onwards.
    In General 
  • Alliance of the Alienated: Nearly everyone in Rentarou's harem comes from a Friendless Background and are brought together by falling in Love at First Sight with Rentarou. Together, they work to support one another and forge bonds with each other through numerous adventures.
  • Balanced Harem: Rentarou does everything in his power to invoke this trope, no matter how many girlfriends he collects. The series' Tagline is "the romcom with zero losing heroines", after all.
  • Custom Uniform: Outside of Rentarou, Hakari, Chiyo, Hahari, and Kimari, all of them wear distinct uniforms to school.
  • Early-Bird Cameo: The anime adds some of the later girlfriends to the background of early episodes.
    • Shizuka, Nano, and Meme all make a brief cameo in Rentarou's class in Episode 1.
    • Kurumi, Iku, Mimimi, and Meme all appear at the end of Episode 12 as a Sequel Hook for Season 2, where they all make their official debut.
    • Chiyo and Momiji can both be seen from behind in the Middle School hallway in Episode 13.
    • In both the anime and the manga, Mei and Mai make brief appearances as Hahari's maids several chapters/episodes before properly meeting Rentarou.
  • Egocentric Team Naming: Takes the name from Rentarou himself, after all. Not that any of the Girlfriends have any issues with that.
  • Everyone Is Bi: Played with. The entirety of the family share a love for Rentarou, but a good chunk of the girls in the family appear to land somewhere in the middle of the Kinsey Scale with the amount of Homoerotic Subtext they share, while the rest are Ambiguously Bi at worst. The trip to Loveney Land highlights this in particular as a majority of the challenges need pairs to love each other romantically to pass. Some appear to be all but said to be bisexual, namely: Hakari and Karane, who have a Running Gag of accidentally or impulsively kissing each other and are treated as genuinely being in love with one another by the narrative; Nano, whose bonds with Shizuka and Mimimi evoke the most emotion out of her after Rentarou; Hahari, who openly goes after the rest of the girls as much as Rentarou; Kurumi, who has indulged Hahari's antics like sucking her breasts despite normally being annoyed and is easily flustered around the other girls, namely Shizuka and Himeka; Meme, whose flustered reactions towards those she finds cute, Mimimi in particular, are heavily reminiscent of "bi-panic"; Mai, who openly loves Mei just as much as she does Rentarou while envisioning herself as the heroine of an Otome style game with the other girls as the capture targets; Eira, whose heart is sent into overdrive when Mei gains the urge to tease her by play flirting with her; and Kimari, whose "friendship" with Usa-chan comes across as a "Romantic" Two-Girl Friendship and rule-breaking kink leads to her treating it like forbidden love at times.
  • Family of Choice: Rentarou names the harem "Rentarou's Family" in Chapter 14, framing how he sees them - they're just as much a family as they are a harem. The girls collectively react with a hngh!.
  • Friendless Background: Very few of them had any friends before they met Rentarou.
  • Locked Out of the Loop: Rentarou refuses to tell any of them about the danger of not falling in love with him, fearing that they would feel obligated to enter a relationship with him if they believed their lives were at stake and much preferring they'd rather genuinely fall in love with him.
  • Love at First Sight: Downplayed. Since they're all soulmates, all the girls fall head over heels for Rentarou the moment they lock eyes with him. However, it usually takes at least one chapter of actually getting to know each other for them to confess to him or alternatively accept his confession.
  • Marry Them All: The series' main Taglines always mention it has "zero losing heroines", after all. Rentarou affirms his intention to invoke this trope in Chapter 146.
  • Ragtag Bunch of Misfits: Being a Cast Full of Crazy, when the harem forms a team they become this, but since they're also True Companions, they don't have much trouble working together. As an example, the team they form to rescue Hakari in Volume 3 features a Love Freak who'd do anything for his girlfriends, a Tsundere who is Only Sane by Comparison, a Cute Mute bookworm who communicates using her phone's text-to-speech app to quote her personal library, an Emotionless Girl who's efficient at everything she turns her hand to, and a Mad Scientist with Dual Age Modes who can make drugs that do anything setting out to rescue their missing member, a Lovable Sex Maniac with a devious streak, from her Knight Templar Parent mother, and the teams only get weirder as more girlfriends turn up.
  • Selective Obliviousness: Despite the series having No Fourth Wall and several members of the family shown having access to physical copies of the manga, none of the Rentarou Family aside from Rentarou himself are aware of the danger of not falling in love with him.
  • True Companions: There are several occasions where the harem demonstrates that calling themselves a family isn't just for show:
    • In Chapter 15, Rentarou decides he's going to rescue Hakari and go on the run together to try and escape her Knight Templar mother, and asks the rest of the harem - Karane, Shizuka, Nano and Kusuri - if they'll wait for them. Instead, they say they're coming with them, knowing they're giving up on their families, homes, and school.
    • Rapko undermining Shizuka's self-confidence in Chapter 35 during the baseball match against Jurassic High earns the opposing team's the family's collective wrath, and they go all-out to make a comeback.
    • The family collectively volunteers to protect Meme from the newspaper club in Chapter 55.
    • The relay race in Chapter 99 showcases how the harem has become this for its members; they've spent so much time together, and have become such close friends, that they're able to operate in sync without communication. The efforts and expectations of the rest of the harem encourage each member to do their best.

The Determined Male Lead

The honest kid that got 100 rejections to his confessions before the beginning. Now the God of Love has seen fit to answer his prayers, but with a twist: he'll be given 100 soulmates as his girlfriends and he must take them and love them or they'll die. Being the kind of guy he is, he fully applies himself to the task.


  • Abhorrent Admirer: In the prologue, he was this to Asakawa, who had nothing bad to say about him but was sickened by the idea of dating him for some reason she couldn't even explain.
  • Above the Influence:
    • He won't accept a confession if he or his new girlfriend are under the influence of a drug, or he thinks a girl isn't conveying their honest feelings. He won't even let himself dream, literally dream about anything lewd with his girlfriends.
    • This is why it's obvious from the start of Chapter 119 that it isn't really him when Momiji swaps bodies with him to grope the other girls.
    • At the end of Momoha's debut arc, she once again tries to proposition Rentarou into sex. Rentarou comes very close to giving in, but Momoha passing out is what lets reason win.
  • Accidental Pervert: In Chapter 233, he finds his hand on Hasuha's breast when she turns around and runs into him too quickly for him to do more than raise his hands.
  • The Ace: Every rejection Rentarou received inspired him to work harder on improving himself. It is lampshaded how many positive features he actually has when he gets his 100th rejection, and it doesn't make sense he keeps getting rejected. He is athletic, nice, smart, and sociable. (Turns out the rejections were the God of Love's fault too.)
  • Ain't Too Proud to Beg: While he sometimes counters threats to the girls in loudly (occasionally disproportionately) violent ways, he's just as likely to humble himself on hands and knees, especially if the problem is a purely social one.
  • All-Loving Hero: It doesn't matter what the situation is or how badly somebody has hurt him, he loves them anyway. The flip side is that he can't reject anyone, and even pretending to do so causes him to start vomiting blood.
  • All Take and No Give: Inverted; when it comes to his girlfriends, Rentarou is All Give and No Take, as he's so devoted to making them happy that his own happiness is an afterthought. He encourages Mimimi to stay in a play even though he hates the idea of her kissing someone she doesn't love, tries to support Ahko's desire to upload a video of themselves to the internet despite his concerns on what would happen, and is content to do nothing but eat during his date with Kurumi. Each time, Rentarou's girlfriend noticed something was wrong and urged him to be honest about his feelings.
  • Amazon Chaser: He's expressed admiration over how strong some of his girlfriends are, such as Kishika's swordplay.
  • Balloon Belly: At the end of the Season 1 title sequence after being fed by the first five girlfriends.
  • Because You Were Nice to Me: A lot of his girlfriends were struggling with their lives due to their various extreme quirks and fall for him because he's the first person in their lives to actually support them and help them overcome the most crippling aspects of their mindsets.
  • Berserk Button: Rentarou is a pretty nice guy, but he will flip out if you insult or threaten any of his girlfriends. Or vice versa. Someone making his girlfriends cry has caused Rentarou to dual wield shopping carts to attack the perpetrators, charge them despite being unable to walk and being dubbed "the boyfriend yokai" by the narration, and Horrifying the Horror by inexplicably defying the reality-warping power of a god (and in the process, contorting both his visage and his body into something very grotesque) to threaten him into submission.
  • Big Damn Heroes: He doesn't just help his girlfriends deal with their particular struggles, he also saves their lives countless times, beginning with Hakari in chapter 19. He also saves them all when they're stranded on a floating island due to acquiring temporary Rubber Man powers in Chapter 183-184.
  • Big Ol' Eyebrows: He has noticeable thick eyebrows.
  • Can't Act Perverted Toward a Love Interest: He firmly holds this mentality, refusing to think about or do anything lewd to his girlfriends, feeling it would be "impure" of him to do so; going by his brain diagram in his "date" with Mei, while there is a spark of desire in his mind, it's far, far outweighed by his love. Momoha's come closest to getting him to give in, but so far he's just barely managed to hold fast.
  • Catchphrase: Whenever he introduces a new girlfriend to the others, he says, "And so, due to how things panned out, would you guys mind accepting [new girl] as my newest girlfriend...?!" The official manga translation doesn't follow the exact same template for every girlfriend introduction.
  • Comically Invincible Hero: Rentarou is such a Love Freak that he can do virtually anything thanks to The Power of Love. Some of his insane feats include beating up more than a dozen men to stop them from bothering his girlfriends, running hundreds of miles around Japan to scout dating spots, and flying through the air to catch his girlfriends after they're launched out of a building. This has scaled up over time, in part thanks to his lack of experience at the beginning. After Hahari joins the harem, not much poses any real obstacle to him anymore.
  • Commonality Connection:
    • He can have such convincing heart-to-hearts with the girls because he is attuned to the similarities between him and them. For instance, he knows what it's like to have more than one soulmate, enabling him to help Hahari resolve the conflict of loving him and her deceased boyfriend at the same time.
    • This runs into a wall when he meets Yaku, however, because as far as she's concerned, she's lived so much longer than him he stands no chance of understanding how she thinks. When she says she appreciates him flirting with her, he protests he's being serious, to which she says, with a certain degree of affectionate amusement, that maybe someday he actually will get her to take him seriously.
    • When first encountering Suu, Rentarou takes note of how she describes her love for numbers and directly links it to how he feels about his girlfriends. For example, when she talks about how seeing numbers in different forms, such as Roman or Arabic numerals or kanji, is like seeing them in new outfits and hairstyles, Rentarou immediately understands it as he imagines Kishika and Karane in different styles. Suu would later note that Rentarou took her love of numbers completely seriously, which prompts her to reciprocate by putting more effort into integrating with the rest of Rentarou's Family than she might otherwise have.
  • Complexity Addiction: He’s prone to coming up with convoluted solutions to problems in order to please his girlfriends.
    • In Chapter 2, he comes up with a complicated kissing game so he could kiss Hakari and Karane without anyone knowing who got his Sacred First Kiss. The game doesn’t go as planned, and they ultimately agree to a three-way kiss.
    • In Chapter 3, he transcribes Shizuka’s favorite book by hand for a text to speech app, when a sensible person would download an ebook or Kindle version for said app. Subverted in the anime, where Shizuka mentions that the book was never released in a digital format.
    • In Chapter 24, he uses ingredients from different foods to improvise a recipe for a dish that Kurumi was craving when every store in the area had sold out of them.
    • In Chapter 44, he resolves Kurumi’s desire for a French kiss by setting up Hahari as a Body Double for him and arranging for her to blindly French another girl at random beforehand so that none of them could claim they weren’t French’d before Kurumi.
  • Compressed Vice: Chapter 166 has him lack self-confidence and try and fail to look cool in front of his girlfriends. This despite him defying a god with impunity just two chapters earlier.
  • Crazy-Prepared: Rentarou is frequently prepared for any situation, both the probable and improbable. In the first chapter alone, he predicted that Hakari couldn't finish a drink by herself, so he also got a smaller one for her just in case.
    Rentarou: Okay, I got my towel and my permanent marker ready...
    Karane: Why are you carrying those?
    Rentarou: I carry pretty much anything you can think of so we'll be prepared for whatever happens.
  • Cursed with Awesome: Thanks to an error, he's given the chance to meet 100 girls who will love him after being rejected 100 times. Unfortunately, he has to make them all happy, as him choosing just one will cause the others to die of misfortune.
  • Deconstructed Character Archetype:
    • Of the standard Harem Genre protagonist. Not only is he not Oblivious to Love, but his Love Freak nature made him put a ludicrous amount of effort into being the perfect boyfriend, even before he started being showered in soulmates. His characterization illustrates just how insanely capable a Harem Genre protagonist would have to be to satisfy every member of his harem.
    • Also the All-Loving Hero: the ability to accept everyone he loves comes with the inability to reject them without serious consequences. And said acceptance doesn't always come easily even for him, as seen with Momoha and Tama.
    • Also I Just Want to Be Loved. Rentarou needs to be loved and needed, to have his affections returned, and even his formidable willpower could only hold out for so long in the face of a hundred rejections; before meeting the girls, he was depressed, forcing himself through the day, and on the verge of just giving up on his romantic feelings. His insecurity from those rejections is likely why he pushes himself to self-destructive extremes to make the girls happy.
  • Decoy Backstory: In Chapter 30, Rentarou tells Mei about a time when he played a word game with Kusuri, and afterwards was unable to properly say a similar-sounding phrase. When Mei laughs at the story, Rentarou reveals that it actually happened to her master Hahari, and not him. The resulting Oh, Crap! face is what finally gets her to open those bright eyes, which was Rentarou's objective in telling the aforementioned story.
  • Desperately Craves Affection: He spent his entire life improving himself in as many areas as possible in the hope of becoming someone's ideal boyfriend, racking up 100 rejections by the time he graduated middle school. By this point, his efforts have shaped him into a being whose capabilities know very few bounds.
  • Determinator: Goes above and beyond for love, even to the point of absurdity. In the very first chapter he spends 12 hours crawling in the dark looking for two four-leaf Pink Clovers, and his efforts only grow from there.
  • Deus ex Machina: Played for Laughs, as he will outright tear the ending panel off a chapter if it ends on a sad note for any one of his girlfriends, and claimed while dreaming that he would murder the writer and rewrite the series himself if one of them ever were to die, ensuring that the manga will get a happy ending no matter what. A bonus chapter in Volume 9 features the girlfriends in diverse fairy tale-esque Damsel in Distress predicaments, only for the penultimate page to introduce "Prince Rentaromeo", who literally whacks all their troubles away and marries all of them in the last chapter.
  • Disproportionate Retribution: While normally his violently protective nature is justified, he can occasionally get overzealous in ensuring his girlfriends are happy. Case in point, Chapter 104 sees him battered and bloody next to a pile of bodies, having beaten people in the forest up so they wouldn't disturb Shizuka, Mei, Meme, Yamame, and Ahko's trip to find a secret flower bed. While this is justified with the perverts and pranksters, it's harder to justify beating the shit out of the guy who was looking to prove Tsuchinoko were real for a day straight or the guy trying to reach enlightenment and become one with the universe. (The omake implies they were dangerously unhinged in some way, like the guy who'd been searching for Totoro, although Rentarou had become equally unhinged himself.)
  • Doesn't Mind a Beating: Rentarou is routinely subjected to physical beatdowns by Karane, but is perfectly willing and able to endure it every time. This is despite the fact that she managed to put him in a full body cast at least once.
  • Dragged into Drag: This is one of the few things that can make Rentarou flustered or nervous.
    • In Chapter 20, he's made to cross-dress by Hahari, causing him to pass out from embarrassment when the other girls see him.
    • Hahari does it again in Chapter 47, this time having him put on a fashion show for her.
    • In Chapter 100, he gets put in a white dress due to tying for first place in a popularity poll with all of his girlfriends.
    • Yet again in the second half of Chapter 111 in order to get into a cafe exclusively for Gyaru Girls.
    • The bonus page for Chapter 163 follows up on the chapter's promise to have Rentarou in female Elegant Gothic Lolita clothing.
    • He does this of his own accord in Chapter 167 to play mommy with the newest round of babyfied girlfriends.
  • The Dulcinea Effect: Rentarou will always give the shirt off his back to his soulmates from day one of meeting them, even if they act rude to him at first. Before meeting the loony bunch that is the Rentarou family, this appeared to be one of his main issues, as he confessed to girls whom he barely knew (Asakawa's flashback of him in the anime only feature her staring at him from a distance, and the girl he confessed to in pre-school had only comforted him once before he fell for her), to the point where his friend A called him a love monster.
  • Early Installment Character-Design Difference: Rentarou had blue eyes in early artwork, but this was changed to brown eyes in later ones.
  • Equivalent Exchange: Before Rentarou could meet his 100 soulmates, he had to go through 100 rejections first.
  • Establishing Character Moment: The manga opens with Rentarou confessing to a girl who immediately rejects him; it's soon revealed that she's the 100th girl to reject him, and he made his first confession when he was 8 months old. This establishes him as a Love Freak. On his first day of school, after meeting his first two soulmates, he buys an obvious charade of them hurting their legs from their Crash-Into Hello. This establishes his Love Makes You Dumb tendencies. When they both confess to him, he punches himself in the face for considering the idea of two-timing them in secret. This establishes him as an All-Loving Hero. In the following chapter, he sets up a convoluted kissing game to prevent his first two girlfriends from being jealous of the other having his First Kiss. This establishes his penchant for Zany Schemes in making his girlfriends happy.
  • Even the Loving Hero Has Hated Ones: The one person who can quickly and easily spark Rentarou's ire is the god that gave him his 100 soulmates in the first place. While he's grateful for the soulmates themselves, he has not forgotten that the entire reason they're a thing is the god's screw-up and that fact places the girls in danger. Rentarou is quick to threaten arson on the god's shrine whenever they meet. Lampshaded in Chapter 123, where Rentarou compares the way you behave with someone you like against someone you don't like and the only person he can think of in the second category is the God of Love.
  • Everyone Has Standards:
    • In Volume 2's bonus fanservice chapter, he opts out of Hakari's "guess that breast" game, saying he's going to quit being the protagonist if he has to do something crude like that to the girlfriends to make someone else happy.
    • In general, while Rentarou has no problem being publicly affectionate with his girlfriends, he'll never cross the line to anything sexual or perverted, to the extent that he'll usually have something prepared beforehand if he knows if he'll be dealing something of that nature. One example that also involves Hahari is when he agreed to let her do anything to him for an hour as Mei's thank-you gift to her, he also wore a chastity belt that would pierce his junk with countless needles if it detected arousal for said hour to stop Hahari from just having her way with him.
  • Expository Pronoun: Being a passionate Love Freak Determinator, he uses ore.
  • Fashionable Asymmetry: In Chapter 146, he manages to wear both Japanese and Western groomswear by splicing them together Two-Face style.
  • Feels No Pain:
    • He barely reacts to Karane jamming food into his eye by accident anymore. Or even turning his head 180 degrees.
    • Subverted in Chapter 96. While trapped inside a giant vase on the roof, Rentarou felt his spine crack after Hahari landed on it, which only got worse with the added weight of Kusuri, Iku, Kishika, and Momiji. After those five girls leave he thinks about heading to the hospital, but when he discovers that his spine is fully healed, he chalks it up to being healed by the experience of being in the vase with the girls.
  • First Friend: To many of his girlfriends, owing to their Friendless Backgrounds.
  • First-Person Smartass: While Rentarou remains polite whenever talking to a new soulmate, his internal thoughts often reveal his misgivings or concerns about the girl's quirks or flaws. However, he quickly learns to accept the girl's eccentricities and stops viewing their behavior in a negative light.
  • Friendless Background: Considering he racked up 100 rejections by the time he graduated middle school, and his unnamed friend disappears from the story shortly after the graduation ceremony, it's a safe bet that he never had any long-term friends before the titular five-score female companions with great, great, great, great, great affection for him.
  • Good Samaritan: It's not just his soulmates he helps out. In Chapter 1, he spends four hours helping an old teacher find his contact lenses.
  • Graceful Loser: Despite having been rejected 100 times throughout his life, the guy remained positive and eager to try out for a new romance.
  • Guile Hero: He's often quick to think up ways to please his girlfriends and/or help them escape from some kind of trouble.
  • Healing Factor: One thing The Power of Love gives Rentarou is an incredible ability to heal. He can recover from injuries that put him in a full-body cast with no lasting consequences, heal a fractured spine by being close to his girlfriends, and reform his heart after it exploded when a girlfriend begs him to come back.
  • Heroes' Frontier Step: Chapter 85 ends with him explaining to the God of Love that he has no intention of revealing to any of his girlfriends that they would die if he didn’t love them, since he doesn’t want any of them to date him just because their lives depend on them doing so. This resolve is what proves beyond doubt that he always has his girlfriends’ best interests at heart and that nothing will ever change that.
  • Heroic Spirit: If being able to survive 100 rejections by the time he graduated middle school doesn't embody this trope, nothing does.
  • Hidden Depths:
    • Think he's just another bland harem protagonist? Nope. Not only is he fully aware of his Love Interests' feelings and can help them through their struggles, but he's capable of serious heroics when push comes to shove. Hold one of his girlfriends hostage? He'll sneak into where she's being held and bust her out, even if it means they'll have to go on the run for the rest of their lives. He also worries about failing to be a good boyfriend to his soulmates and tells Hahari that she or anyone else can dump him if he turns out to be a disappointment.
    • Chapter 85 and the Volume 1 bonus story reveal that being rejected 100 times took its toll on him, leaving him on the verge of giving up on love because no one loved or needed him, but meeting the girlfriends pulled him back. Chapter 177 shows he'd sunk into depression, struggling to get himself through the day.
  • Hopeless Suitor: For 100 different girls he confessed to, Asakawa being his last rejection. Aside from the God of Love accidentally setting all his soulmates to his High-school life, it's implied Rentarou was simply too forward with girls he barely knew.
  • Horrifying the Horror: He's terrified a Jerkass God into submission, and spooked the Vice-Principal into thinking he was a youkai while he was maniacally searching the grounds.
  • Hyper-Awareness: He's very good at paying attention to his girlfriends. He's able to understand what Nano is saying even with something in her mouth because he loves her. And with his eyes closed he's able to guess that a circular badge has Shizuka's image on it.
  • Hypocritical Heartwarming: He always tells his girlfriends to value themselves and reassures them that he will always love them just for being themselves. At the same time, he holds himself to the highest possible standard, being quick to endanger his own life to protect them and even contemplate suicide if he thinks he's failed to meet their expectations, apparently not internalizing that they value him as much as he values them.
  • I Didn't Tell You Because You'd Be Unhappy: He has never told any of his girlfriends that they would die if he didn’t love them because he doesn’t want anyone to date him simply because their lives depend on them doing so, seeing such a predicament as Questionable Consent at best and a Fate Worse than Death at worst.
  • I Just Want to Be Loved: His entire existence pretty much from the time he was born revolves around wanting to be the object of someone’s affection, making his first attempt at a confession when he was 8 months old and racking up 100 rejections by the time he graduated middle school.
  • Inconsistent Spelling: The scanlation (and the fandom, as a result) uses "Rentarou Aijou", The Other Wiki uses "Rentarō Aijō", the anime and the official manga and anime translations use "Rentaro Aijo", and the earliest version of the anime website used "Rentaro Aijyo".
  • Inelegant Blubbering: He is frequently moved to tears by the love his girlfriends show for him, and this can at times escalate to outright bawling, such as when everyone takes turns telling him what they love about him in chapter 37.
  • Insecure Love Interest:
    • He has a tendency to think of himself as falling short of the girls' standards, particularly when it's something he can't overcome through effort alone, like age or status. The girls disagree, seeing him as going above and beyond for them.
    • He also has a bit of a hangup over being the boyfriend in a relationship, wanting the girls to rely on him and know they can do so. However, getting the chance to rely on the girls is one of the things that gets his heart throbbing.
  • Jerkass Ball: While he is normally kind and considerate to his girlfriends, Chapter 44 presents Rentaro as unusually manipulative and avoidant of Kurumi's problems. Instead of directly helping Kurumi with her French kiss craving, Rentaro comes up with an overcomplicated plan by using Hahari as his Body Double to kiss Kurumi for him as well as one of his girlfriends hiding under the bed without their knowledge.
  • Jerkass to One: Though he'll get violent with anyone who harms his girlfriends, the only person he's consistently hostile towards is the God of Love, for his reckless mistake that endangered the lives of 100 girls. Even before it's revealed it was his fault, Rentarou threatens to burn down his shrine if it turned out he was lying about Rentarou finding true love in high school.
  • Kill It with Fire: Notably, he tends to solve problems either through the Power of Love... or through (almost) setting things on fire, such as when he threatened to burn down the Love God's shrine, or the time he pulled out a torch in order to "negotiate" with the newspaper club. Or both, as seen with Nano's introductory episode. He tones this down after meeting Yamame, who has pyrophobia, but it still pops up from time to time.
  • Kryptonite Factor: As formidable as Rentarou is, running on The Power of Love means he also has a weakness to anything that goes against that love. A girlfriend expressing genuine hate towards Rentarou can break his heart, and Rentarou himself doing anything cruel to his girlfriends can seriously hurt him, even if it's just pretend or with consent. When he pretended to reject Iku's confession, he vomited blood, and when he pretended to dump Iku at her request, his heart exploded.
  • A Lady on Each Arm: A routine occurrence for a boy destined to have 100 soulmates.
  • Likes Older Women: A number of the girls are older than he is (some of whom are adults), though he proudly claims to like all women. He makes it clear to Hahari that he actually prefers her age the way it is when she expresses insecurity about it because that's the age she was when he fell in love with her. Despite this, he gets annoyed when this is pointed out, like in Chapter 180 when he is mistaken for Eira’s little brother and is unable to come to her defense.
  • Love Epiphany: Shizuka's confession in Chapter 3 / Episode 3 marks the turning point in the story when Rentarou realizes that his feelings for each of his girlfriends are genuine and not Because Destiny Says So or because he doesn't want them to die.
  • Love Freak: Fell in love for the first time as a baby, and has confessed to and been rejected by 100 girls before the start of the series.
  • Love Makes You Dumb: While Rentarou is capable of coming up with clever solutions, his love for his girlfriends has caused his judgment to be impaired at times.
    • He buys an obvious charade of his first two girlfriends hurting their legs from their Crash-Into Hello with him.
    • Although Rentarou was running away from Shizuka while she was a Kiss Zombie, he came back to help her when she tripped and fell on her face.
    • After a spy threatened to shoot Kusuri in the leg when she tried to be a Human Shield to Rentarou, Rentarou himself tried to shield Kusuri, even though he was the one the spy was trying to shoot in the first place. Everyone, including Rentarou, calls him a moron for this.
    • When Mai tried to force-feed him addictive cabbage, Rentarou eagerly accepted it even though he knew it was literally addictive.
    • When the family crashes on a deserted island, Rentarou warns everyone from drinking the spring water or eating the fruit only to immediately do it himself, using himself to test to see if it's poisonous. Nano lampshades that his survival skills are "out of this world" after he mistakes her suggestion of using the "universal edibility test" to be where "if the boyfriend eats it and is fine for eight hours, his girlfriend can eat it safely", Rentarou thinking she's praising him only for Momoha to have to play the Straight Man and tell him Nano wasn't.
  • Made of Iron: Oh good lord. This is a young man that will get himself thrown into situations that will break his bones, make him a bloody mess and potentially even outright kill any ordinary individual, and Rentarou bounces back every time shortly afterwards like it never even happened. This is actually an in-universe trait, because despite being a Comically Invincible Hero, he very much still feels all the pain and actually wonders if he should go to the hospital at one point — only to realize he miraculously recovered in the time between getting said injury and thinking about getting it treated.
  • Martyr Without a Cause: Rentarou will eagerly risk his health or life for his girlfriends, even for fairly minor situations like considering breaking the bones in his hands so he could retrieve Chiyo's glasses when they slid under a vending machine.
  • Meaningful Name: Both his first and last name contain a kanji meaning "love", and Aijou literally means "feelings of love".
  • Messiah Creep: As more and more girlfriends are added to his harem, his abilities gradually increase as he does everything in his power to satisfy the girls, who would all be doomed to death if he didn’t love them.
  • Murder Is the Best Solution: Downplayed and Played for Laughs. Whenever Rentarou thinks there is a physical threat to the girls, they're being insulted, or that someone may be trying to be perverted towards them, his first instinct is to beat the ever-loving shit out of the perpetrator even if he's left bloody in the process. Chapter 136 for example has him spot someone watching the group from a window before hiding when he notices them, and thinking they could be someone trying to peep on Momoha whenever she's passed out drunk. An x-ray of his brain immediately appears showing his first thought is to exterminate them. It ends up backfiring on him in that case, since it was actually the Vice-Principal running around with no makeup on, his rushing headfirst causing him to get a good look at her, and scaring him to the point he passes out.
  • Mysterious Past: In stark contrast to his girlfriends, a large amount of Rentarou's own history and family life is unknown. The only things known are that he's been a Love Freak since infancy, suffered 100 rejections by the time he graduated middle school, started a "girlfriend joy fund" as a toddler and spent years investing in it, saved his uncle Hiro from being run over by a tanker truck once, and that his parents are both teachers. Outside of that, most of his past is at best guesswork, like the idea he had a Friendless Background since his only known friend before going to High School was Friend A, who disappears from the story before Rentarou first meets the God of Love.
  • Nice Guy: One of the nicest guys around. Rentarou is always all too eager to help those in need, soulmates or not. Even Asakawa has nothing bad to say about him when rejecting him.
  • No Infantile Amnesia: Remembers his first confession at 8 months old.
  • Not Himself: One chapter begins with Rentarou forcing himself on all the girls to grope their chests—which of course is because it's not really him, but Momiji in his body. The real Rentarou begs her to stop when he finds out.
  • Oblivious to Hatred: He was completely unaware of Mai's hostility toward him before she made eye contact with him.
  • Oblivious to Love: A very strange Double Subversion. Rentarou is extraordinarily perceptive to his girlfriends' feelings and unspoken concerns, and even the love in outside relationships or fiction. But any time his girlfriends have an intimate moment with each other (typically Hakari and Karane, but occasionally even with Hahari's antics), he attributes it to their just being good friends and fails to see the romantic subtext. Perhaps a more accurate description would be Oblivious to Lust.
  • One Head Taller: Rentarou is taller than most of his girlfriends. The only exceptions are Nano and Eira, who are about the same height as him; Mimimi and Shiina, who are slightly taller than him; and Yamame, who's much taller than him (and everyone else).
  • Out-of-Character Alert:
    • Pretending to reject Iku, after she saw him holding hands with Nano, to the point where she even felt that her heart was breaking because he knows that the girls would actually die if he rejected them. He did this because Iku is a major masochist who enjoyed the rejection, but even this makes him literally vomit Blood from the Mouth due to the act.
    • The girls freak out when he starts groping them all of a sudden. It turns out that's not actually him.
  • Overly Nervous Flop Sweat: Every time he introduces a new girl to his existing girlfriends, no matter how many times they've all done this song and dance.
  • Paralyzing Fear of Sexuality: While it's given little if any dialog, he can't handle getting too physical with the girls; kissing is fine, but not much more than that. During his date with Naddy in Chapter 156, he admits he's uncomfortable with her hugging him because she's too beautiful for him to get used to it... but his internal monologue reveals he's also come to enjoy her hugs, and he's awed by how her body feels when he finally decides to hug her back. It's not too hard to suspect that his discomfort with how he felt about these attractive girls getting up close and physical with him was a factor in him trying to avoid that. He pretty much confirms it in Chapter 180, saying he's afraid he wouldn't be able to hold himself back.
  • The Perfectionist: When it comes to being a boyfriend. His reaction to being rejected so often was to keep improving himself, and he kept it up afterward in order to make the girls happy. However, his insecurity about living up to the girls' standards and keeping them happy means he can take it to unhealthy levels (getting so obsessive he starts hurting himself, suppressing what he actually feels in the name of their happiness, etc.). The girls step in to stop him when they see it happening.
  • Phrase Catcher: "I love you."
  • The Power of Love:
    • Rentarou is explicitly capable of superhuman and outright supernatural feats if it's for the sake of his girlfriends. He manages to resist the power of the God of Infinity to come to Matsuri's aid, ignoring the mind-shattering pain that normally comes with doing so, then shrugs off the god increasing his divine power tenfold to control him again, rotating his head a full 180 degrees as he terrifies the god into submission.
    • He asserts in Chapter 202 that he can do anything as long as he has to live up to the wishes of the people he cares about, and on prior record he's not being hyperbolic.
  • Power-Up Food: He drinks plenty of milk to build up strong bones for dealing with the task of looking after his girlfriends, especially the beatings he receives from Karane.
  • Rage Against the Author: Rentarou frequently calls out the author for putting his girlfriends in danger or sexualizing them, at one point threatening to quit as the protagonist when Volume 2's Breather Episode's plot involves feeling his girlfriends' breasts to guess who they are. In Chapter 196, he vows to kill the writers and the staff if they ever kill off one of his girlfriends.
  • Rage Against the Heavens: Rentarou is fully prepared to challenge the powers that hold sway over his world, be they gods or publishing executives, if they mess with him or the girls. He only backs down against the Big Cheese because it won't solve anything, not because he thinks he can't do it.
  • Reincarnation Romance: It's subtly implied that Rentarou is the reincarnation of Yaku's late husband, occasionally seeing Yaku as if she was in her more adult form despite never actually seeing it and being able to understand the sentiments behind her husband's gift of a vase to her despite never having met the man and only knowing of him as "taciturn". This in turn suggests the reason Yaku is one of his soulmates is that his love for her was able to transcend lives.
  • Second Love: He serves as this to Hahari and Yaku after the deaths of their first loves. (Technically, he's this to Momiji and Suu as well, but Momiji's first love was the softness of Hahari's breasts, Suu's first loves were a set of numbers, and neither mind sharing.)
  • Secret-Keeper: As affirmed in Chapter 85, he deliberately hasn't told any of his girlfriends about the whole "Unreciprocated soulmates = dying" thing, because he doesn't want them to essentially date him under duress.
  • Secretly Selfish: Highly Downplayed. When the God of Love asks Rentarou in Chapter 85 why he hasn't told the girls about the nature of "soulmates" nor why he doesn't just tell any future soulmates that to instantly get them to date him, Rentarou says he doesn't want the girls to be dating him just because they're afraid of dying, he wants them to genuinely love him just as he genuinely loves them. He admits it's likely his self-satisfaction talking, but he wants the people he loves to be together because they make each other happy rather than out of obligation, and that even if he can't forgive the God of Love for putting a hundred girls lives in danger because of a stupid mistake, he's honestly grateful since he's now got so many people in his life who genuinely make him happy after spending so many years suffering heartbreak.
    Rentarou: Well... this may... just be my self-satisfaction talking, but I don't want the people I love to date me just because they'll die if they won't. I want them to be with me because it makes them happy. I want them to experience undiluted love. And that applies to both before, and after we would begin dating. If you're forced to live out your life in a relationship you don't wholeheartedly wish for yourself, that's hardly any different from being fated to misery and death either way. — I can never forgive [the God of Love] for putting so many people in such serious danger. But... even then, I can't express how grateful I am for- for just... everyone, who I have in my life now. Thanks to you, I've never been happier.
  • Seen It All: He's so used to dating dozens of girls at the same time that it doesn't even occur to him to mention how many girlfriends he has to a girl who wants an abnormal boyfriend until the very end of her debut chapter.
  • Self-Proclaimed In-Law: Rentarou has met a handful of his girlfriends’ parents and has referred to two of the dads as “Father In Law” and attempted to call one of the moms “Mother In Law”.
  • Self-Punishment Over Failure: Rentarou will frequently hurt himself if he believes he's failed or hurt his girlfriends in any way.
  • Staring Down Cthulhu: One of the craziest things he does for love is staring down the God of Infinity after he acts like a Jackass Genie to Matsuri. After Rentarou threatens to kill him, the god simply mind-controls Rentarou again with 10 times the power and sends him running off... only for our hero to twist his neck like an owl and threaten him again, cowing the god through sheer monstrous intimidation.
  • Straight Man: Half the time, no. He's almost as weird as everyone else. He typically plays this while adjusting to a new soulmate, but there are times when even his girlfriends can weird him out. Typically, he fills this role when Karane or Kurumi aren't around.
  • Supreme Chef: His bento boxes are so good that when he gives one to Kusuri, all the other girlfriends offer to trade their lunches with her, even things like shark fin soup. It is unclear whether it's because he's just that good at cooking or just because they're in love with him, though.
  • Too Dumb to Live: When Kusuri concocts three different drugs that would kill the user by way of Thought-Aversion Failure, he consumes all three of them one after another. The first time can be written off as an accident, as well as the second under dubious logic, but the third time has no such excuse.
  • Took a Level in Badass: It seems like the more lovers he meets, the more powerful he becomes. In Chapter 9, he stands up to a trio of creeps who tried to harass Hakari by begging them to harass him instead. By Chapter 104, the guy is capable of beating up masses of creeps with extreme ease, and has even become The Dreaded to anyone who dares to inconvenience his girlfriends, apparently including the author.
  • Too Kinky to Torture: Downplayed. Rentarou isn't traditionally a masochist in the same vein as Iku, but his love for his girlfriends causes him to appreciate everything about them, pain they inflict included. This largely comes up as a result of the beatings Karane gives him when her tsundere side flares up, as he's quick to reassure her that he likes the beatings she gives him, with Kusuri commenting he looks like a masochist.
  • Trademark Favorite Food: Mei prepared an egg-based lunch for her date with Rentarou because Hahari told her he likes eggs.
  • Turn the Other Cheek: Chapter 39/Episode 19 has him save a Jerkass boyfriend from ruining his clothes, despite said boyfriend ruining his date with Mimimi and staining his clothes with boba tea, rescuing him from karmic justice because he understands the feeling of wanting to impress and defend his girlfriend's honor. The competing boyfriend is so overcome with guilt and honor that he offers to pay back for the clothes he ruined and turns himself in to the security guard.
  • Understanding Boyfriend: No matter what kind of eccentricities his girlfriends may possess, he's always willing to accept them for who they are (although that has its downsides because it includes accepting their bad behavior too, such as Kusuri's recklessness and Hahari's depravity). He also makes it clear that he's okay with his girlfriends changing who they are if that's who they want to be, but not if they hate who they used to be. His acceptance does have its limits, though — he won't accept it if a girlfriend doesn't value herself or her happiness, and will do his best to do something about it.
  • Unique Protagonist Asset: He was destined from birth to receive 100 soulmates after being rejected by 100 girls, whereas the few people who are destined to have a soulmate are usually only destined to have one.
  • Violently Protective Girlfriend: Violently Protective Boyfriend, rather, but kind as he is, Rentarou will fly into a violent rage if his girlfriends are insulted or threatened.
    • Toruru's efforts to expose Meme's face in the school's newspaper is met with Rentarou gathering all 300 printed copies of the said paper to keep people from seeing it and setting out to cheerfully burn the newspaper club down. Though he insists the torch was just a "negotiation tool".
    • He appears to have his limits on how violent he gets. He seemingly draws a gun when Yamame falls over in the street after seeing a driver light a cigarette in his car, but then assures her that it's only a squirt gun.
    • He at one point comes in swinging a pair of shopping carts when Chiyo, Kusuri, and Shizuka are being threatened.
    • In the bonus chapter about Fairy Tales, "Prince" RentaRomeo is described as "obliterating" anything that was giving his girlfriends a hard time.
    • Taken its furthest in Chapter 104, where he protects the girls' journey to find a secret flower meadow in the forest, intercepting the assorted perverts, creeps, and weirdos skulking around in the woods and beating the crap out of them so the girls wouldn't be bothered. By the end, Rentarou is bloodied and battered and the creeps are left in a broken heap behind him.
    • In Chapter 137, the sound of Kishika's crying rouses him from unconsciousness and, despite not having regained the use of his legs, he barrels toward the noise demanding to know who made his girlfriend cry. The sight is terrifying enough that the narration calls him the Boyfriend Youkai.
    • Chapter 159 has him mention doing counterterrorism training and in Chapter 186 he mentions doing anti-Godzilla image training.
  • Weaksauce Weakness:
    • The mere idea of rejecting love is his greatest weakness, fitting for a Love Freak. The idea that he could be rejected isn't so much the problem, however, as it is himself dealing with the possibility of not loving someone back — which physically hurts him to even consider but for the very, very limited cases that a non-soulmate actually earns his ire. Case in point, he fakes a rejection to Iku solely to turn on her masochistic side, and it pains him so much, he proceeds to have such immense Blood from the Mouth that it forms a geyser and physically lifts him up off the ground.
    • One weakness that isn't Played for Laughs is how he can't bullrush his way through a threat to his girlfriends if one of his girlfriends is the source of that threat. Examples of this include Hahari's "bad hair day", Mimimi's unresolved grudge against Nano, and the alternate Nano Eiai's attempted synchronization of their world, which suppresses all of his memories involving his Nano until she kisses him.
  • What You Are in the Dark:
    • When first told that he must make both Karane and Hakari happy, he at first decides to date both of them separately to avoid hurting their feelings, only to then punch himself for even thinking that and instead opt to confess to both of them, making it clear that while this is strange and is essentially two-timing them, he wants to make both of them happy, spending all night looking for two pink four leaf-clovers.
    • The reason he hasn't told any of his girlfriends that they'd die if he didn't accept them was so that everyone could be sure that the feelings they have for one another are 100% genuine and not out of any obligation to prevent an untimely death.
  • Why Did It Have to Be Snakes?: One of his few genuine weaknesses: he's apparently terrified of ghosts and Yōkai, even if it's just an amusement park's haunted house (granted, most of the girls aren't much better, though exceptions among his girlfriends are Nano, Kishika, and Yaku). Hakari's father is the only exception to this rule, which is something the spirit lampshades when he finds out.
  • Yandere: While he's able to keep his emotions in check most of the time, he has a tendency to react violently when one or more of his girlfriends are insulted or threatened. He once threatened two bullies with a pair of shopping carts, and he also pulverized several perverts in the forest that some of the girls were exploring.
  • You Are Better Than You Think You Are: Has given such a speech to literally every girlfriend, and has been the recipient of one himself.

Girlfriends

Girlfriends' families

Family members of Rentarou's girlfriends.
    In General 
  • In the Blood: Many of them have comparable personalities to the girls, and two of them (three counting Chiyo) also share their love for Rentarou.
  • Parental Obliviousness: While many of the girlfriends’ parents are aware that their daughter has a boyfriend, and in some cases have met said boyfriend in person, the number of girlfriends whose parents are aware of the harem can be counted on one hand.
  • Parents as People: Almost all of them do the best they can at raising their daughters, with varying degrees of success. Most of the girls' various quirks can in turn be attributed back to their parents and how they raised them, such as Eira being a Nervous Wreck due to her father trying to stop her from being a Fearless Fool, or Matsuri's penchant for swearing coming from her grandparents raising her.
  • Satellite Family Member: Rentarou's and many of the girlfriends' relatives have made brief appearances or were mentioned in passing. Very few of them have much characterization beyond providing backstory for the girlfriends; most haven't even had their names revealed. The only exceptions to this (besides those in the harem) are Chiyo's father Hiro, and Kusuri's father to a lesser extent, the two being recurring characters that regularly dote on their daughters and have a rivalry with each other as a result. That said, some of the others are particularly noteworthy for their impact on Rentarou and the girls:
    • Rentarou mentions that his parents are schoolteachers and have modest incomes, establishing that he actually works for the affections of his girlfriends.
    • Shizuka's mother played a major role in her daughter being a Cute Mute through her abusive attempts at getting her to talk like a normal person. She's initially seen in a brief flashback in Chapter 3, then takes the spotlight in Chapters 134 and 135 when Rentarou confronts her about confiscating Shizuka's phone for using a text-to-speech app to talk.
    • Hakari's father was a terminally ill middle school student with whom Hahari had herself artificially inseminated. His subsequent passing was the main factor in Hahari vying for younger days, and by extension becoming highly protective of her daughter, whom she believed would make the same reckless choices as she did without her guidance.
    • Mei's Abusive Parents disowned her after being crippled by Loan Shark debts, leaving her to wander through the snow until she was rescued by Hahari, who went on to hire her as a maid.
    • Iku's older brother Ikuya was inadvertently responsible for Iku discovering masochism.
    • Chiyo's mother disappeared from her life before she met Rentarou, and Chiyo wears her glasses as a Tragic Keepsake.
    • Naddy's parents disowned her after she abandoned her Yamato Nadeshiko lifestyle in favor of that of a reverse Occidental Otaku. They had forced her to behave like a traditional Japanese lady through abusive tactics, which led to her rebelling against them and embracing American culture.
    • Yamame's father looks after his daughter quite well. Her refusal to leave the house after accidentally stepping on a bug led him to hypnotize her to alleviate her feelings of guilt and then teach her to walk on stilts so she could feel more comfortable about working in the garden.
    • Yaku and her deceased husband loved each other very much, and Rentarou finds himself navigating the legacy of that relationship - trying to live up to his example, discovering the secrets he hid, etc.
    • Kishika's parents had busy lifestyles that led to her raising her siblings all on her own. Her childhood responsibilities deprived her of the chance to enjoy being a little girl to the point where she secretly wishes to be pampered by someone else despite publicly presenting herself as a mature and knightly kendo club captain.
    • Mai always wanted to be a maid like her grandmother, the previous head maid at the Hanazono estate, and repeatedly asked her to take her to work. When her grandmother finally let her tag along, seeing Mei at work left a big impression on the young Mai, and she decided to try and be just like her. She holds her grandmother in high regard, and wants to show her that she's improved.
    • Rin's parents are strict Moral Guardians who did their best to have her avoid encountering any violence from infancy onwards, fearing her love for it would hinder her upbringing (coupled with her father's fear she'd get her heart broken over being an open Nightmare Fetishist). She caught a brief glimpse of a Resident Evil film as a young girl which, true to the trope of Strict Parents Make Sneaky Kids, had her falling back in love with violence on the quiet.
    • Eira's father is a capoeira instructor who trained his daughter extensively in the art, and as a result she became convinced she could take down anything with a kick, including colds and rivers. When he realized this, he tried to use a Bedsheet Ghost to teach her that there were some things a kick couldn't handle, but instead she developed a phobia of anything that couldn't be kicked. She also has anxieties over her role as Heir to the Dojo.
    • Matsuri met Rentarou while working at her grandparents' yakisoba stand.
    • Kimari's parents are a judge and a police officer who taught her never to break the rules, resulting in her becoming a Principles Zealot.
  • Strong Family Resemblance: The majority of them strongly resemble the girlfriends to varying extents, some sharing certain traits like the Kedaruis' Valley Girl behavior or Eira gaining her father's complexion and mother's hair, while others look virtually indistinguishable albeit older like Momiji and Suu's mothers.

    Hakari's Father 
https://static.tvtropes.org/pmwiki/pub/images/img_0497.png

Voiced by: Akira Ishida (Japanese), Drew Breedlove (English)

A deceased middle school boy who was Hahari's first love and Hakari's father.


  • Absurdly Youthful Father: Was in middle school when he and Hahari had Hakari by artificial insemination.
  • Ascend to a Higher Plane of Existence: Assuming it really is him, Rentarou inadvertently frees him from his regrets about Hahari and Hakari, causing him to move on. He comes back to watch over them after seeing both Hahari's happiness and Rentarou's willingness to risk his own life for that happiness and decides they're too precious to be ignored.
  • Chekhov's Gunman: The series would've ended with Chapter 77 if he wasn't at the gates of heaven to stop everyone from losing their souls after Giving Up the Ghost. Then again, Eira and Mei are able to grab each other’s souls and pull themselves back into their bodies when this happens again in Chapter 185, so his presence may not have been necessary.
  • Deus ex Machina: Averted by the fact that he first appeared around the time Hahari joined the harem and stopped Rentarou from dying during the tentacle hair incident, long before he intervened at the end of Volume 9 to stop Rentarou and the girls from losing their souls.
  • Distinctive Appearances: In the anime, his hair is ice-blue at the base and white further along, evoking both Disease Bleach and his ghostly status.
  • Everyone Calls Him "Barkeep": Neither he nor Hahari ever give his name, so Rentarou calls him "Father-in-law".
  • In-Series Nickname: A downplayed case as he's only called it in the chapter titles and supplementary material, but he's been referred to on occasion as "Papari", a play on the fact his girlfriend and daughter have names ending in "ri" and the word "papa".
  • Know When to Fold 'Em: He knew that he wouldn't live to see his daughter's birth and told Hahari to save her Sacred First Kiss for the man who would never abandon her. He even tells Rentarou that his last regret is Hahari not being able to move on from his death before she met Rentarou and ascends to heaven when Rentarou assures him that he will do whatever it takes to keep Hahari happy.
  • Maybe Magic, Maybe Mundane: In Chapter 22, it's ambiguous whether Rentarou really does speak to him, or whether he's just dreaming. His appearance in Chapter 43, where Rentarou's apparently unconscious while he talks, points to it being him.
  • Older Than They Look: Justified in that he's a ghost and can't physically age anymore, but he's supposed to be close to Hahari in age, meaning he's nearly 30 despite looking like a middle schooler still.
  • Psychopomp:
  • Soap Opera Disease: He was terminally ill with an unspecified disease when Hahari fell for him.
  • Strong Family Resemblance: It's clear Hakari received her looks just as much from him as she did Hahari, as he looks a lot like his daughter just with icy-bluish white hair.
  • Unnamed Parent: Even though he's Hakari's father via artificial insemination, his given name and surname remain unknown since the "Hanazono" surname predates Hahari.

    The Inda Family 
https://static.tvtropes.org/pmwiki/pub/images/indafamily.png
L - R: Karazou (Gramps), Karayo (Gramma), Karato (Li'l Bro), Kararu (Nephew), Karano (Big Sis), Karara (Niece), Karahiko (Dad), and Karana (Mom)

Karane's family, consisting of her mother Karana and her father Karahiko, her older sister Karano, her little brother Karato, her grandfather Karazou and grandmother Karayo, her younger niece Karara, her baby nephew Kararu, and her family's pet hamster Karatarou.


  • Alliterative Family: All of them have given names starting with 'Kara', even those who married into the family.
  • Amazingly Embarrassing Parents: Karane went out of her way to prevent Rentarou from meeting them, fearing that their Shared Family Quirks would make him reconsider marrying her. When he accidentally does, she becomes incredibly anxious.
  • Aw, Look! They Really Do Love Each Other: Despite seemingly being unable to speak to Karane without screaming their heads off at her (the feeling is mutual), they all worry for her (in their own way) when she runs off embarrassed. On her part, she admits to Rentarou that she knows they're a good family, despite being insecure of the possible Generation Xerox affecting her own offspring.
    • It's emphasized more in Chapter 230, when Karato is struggling in a brawl against a bully. With Kishika's guidance, Karane stays hidden and allows him to fight as he wants, but gives a little help by quietly insinuating he likes the girl the bully stole a keychain from. In classic Tsundere fashion, the resulting punch knocks the bully out cold, and as the girl invites him to treat his injuries, he silently thanks his sister.
  • Character Exaggeration: They take Karane's tsundere-ness to the absolute extreme, and seem to be incapable of communicating without sending mixed signals.
  • A Day in the Limelight: Karato returns in Chapter 230, trying to get a stolen keychain back from a bully for a girl he likes.
  • Disappeared Dad: Possibly, since no mention is made of Karano's husband despite her having two children.
  • Jerk with a Heart of Gold: They immediately accept Rentarou into their house, offer him all sorts of food (Kararu even offers his own baby formula), congratulate Karane on dating him, and worry for her when she leaves in embarrassment, all while stubbornly denying their own kindness.
  • Shared Family Quirks: They're all tsunderes, even the ones who married into the family. Considering we only see one set of grandparents, the others might be (or have been) the same as well.
  • Small Role, Big Impact: Most of them only appear in Chapter 144, but Rentarou meeting them leads to him proposing to Karane, which then escalates into him committing to proposing to the rest of them.
  • Tsundere: All of them. Not a single one of them ever says what they mean outright (and yells everything at the top of their lungs), including the baby. Rentarou describes it as "super tsundere family ultimate" upon witnessing it. It's played mostly for laughs, but does give Karane a big hit of angst after Rentarou meets them, fearing that any child she has will share the same trait and that he won't want to have kids with her as a result, reminiscent of someone with a hereditary disease afraid of passing it on to their child.
  • Uncatty Resemblance: Even the family hamster is tsundere.

    Mrs. Yoshimoto 
https://static.tvtropes.org/pmwiki/pub/images/shizukas_mother.png

Voiced by: Madoka Yonezawa (Japanese), Kara Edwards (English)

Shizuka's mother. A strict and hardworking parent, she allowed herself to be blinded to Shizuka's needs based on her own fears for her future, and is now slowly repairing the damage she caused.


  • Abusive Parents: She berated Shizuka for being "a freak" and might have even slapped her, to the point where Shizuka cowered before her on the verge of tears. When she discovers that she's using her phone to talk for her, she confiscates her phone, which prompts Rentarou to confront her about it.
  • Arc Villain: For Chapters 134-135.
  • The Comically Serious: Following her turnaround, her appearances tend to put her in circumstances that are wackier than she's used to, such as waiting outside Shizuka's door while she's kissing Rentarou for at least ten minutes straight, or eating her portion of the bento box that Shizuka made for Rentarou and subsequently meeting him in the childishly drawn dream world of euphoria from Chapter 38. And her composure hardly trembles.
  • Dramatically Missing the Point: She thinks Shizuka's problems are because she isn't being strict enough.
  • Dull Eyes of Unhappiness: Her eyes are dull-colored due to her frustration over Shizuka's inability to speak. She loses this after Rentarou and Shizuka convince her that Shizuka doesn't need to talk to be happy.
  • Early-Bird Cameo: Chapter 134 confirms that the woman appearing in Shizuka's flashback in Chapter 3 is her mother.
  • Heel Realization: She does realize she is wrong at the end.
  • Jerkass Has a Point: While she is forceful in trying to get Shizuka to talk normally, her concerns about how other people respond to the way she “talks” are not entirely unfounded.
  • Jerk with a Heart of Gold: She expresses frustration toward Shizuka's muteness to the point of verbally abusing her as she believes that Shizuka wouldn't be accepted if she doesn't speak normally. When Rentarou and Shizuka convince her that Shizuka doesn't need to speak to be happy, Mrs. Yoshimoto realizes the error of her ways and works on becoming a better mother.
  • Knight of Cerebus: The chapters she appears in are notably more serious than the rest of the manga.
  • Knight Templar Parent: In her mind, any abuse of Shizuka is justified if it allows her daughter to function in society.
  • Love Redeems: Double subverted. She isn't one of Rentarou's soulmates, but her daughter's love for Rentarou is what enables her to realize how forceful she was in trying to get Shizuka to speak like a normal person and return her phone the following morning.
  • My God, What Have I Done?: She almost mentions this trope after Rentarou's Armor-Piercing Question. She returns her daughter's phone the following day and learns to accept Shizuka for who she is rather than make her who she wants her to be.
  • Parents as People: Chapter 135 reveals that her adamance in having Shizuka speak verbally was so she could fit into society after she's gone.
  • Parents Walk In at the Worst Time: Defied. In Chapter 180, she overhears Shizuka and Rentarou making out in Shizuka's room while bringing drinks to them, and decides to wait until they're done before she enters. As the chapter's extra shows, she waited for at least ten whole minutes.
  • Self-Fulfilling Prophecy: As it turns out, her efforts at getting Shizuka to speak normally only made her more reluctant to do so.
  • Silly Rabbit, Idealism Is for Kids!: To call her cynical would be an understatement. Right after meeting Rentarou, she accuses him of being a white knight who's only with Shizuka so he can feel good about himself, dismisses his love for her by calling him naive, and is sure he'll ditch her someday and so tells him not to see her again. Not to mention her motives for trying to force Shizuka to be "normal", believing that she'll never be accepted or able to function in the real world if she can't talk.
  • Simple Solution Won't Work: She isn't one of Rentarou's soulmates, so he can't resolve any issues by having her fall in love with him.
  • Small Role, Big Impact: She only appeared in a single flashback before her proper debut, and all of her appearances are very infrequent, but she played a major part in Shizuka's backstory for being a Cute Mute.
  • There Are No Therapists: If there were, she would have learned that Shizuka has special needs, how to accommodate them, and how Shizuka could overcome them, instead of assuming it was because she wasn’t strict enough, which made things worse.
  • Tough Love: She tried to force Shizuka to speak normally so the latter could survive without her.
  • Unnamed Parent: Her given name has yet to be revealed, even after her serious talk with Rentarou in Chapter 135.
  • Unseen No More: After first appearing in a flashback during Shizuka's backstory, she makes her proper debut in Chapter 134.
  • Well-Intentioned Extremist: She treated Shizuka so harshly because she feared Shizuka wouldn't survive if she never learned to speak properly.

    Mr. and Mrs. Yakuzen 
https://static.tvtropes.org/pmwiki/pub/images/yakusen_couple.png

Kusuri's kindly mother and belligerent father. Just like their daughter, they're both pharmacologists, look like children as a result of her failed Immortality drug, and have a Verbal Tic.


  • Bait-and-Switch Character Intro: Having already been Zing'd with Hahari and Chiyo, Rentarou wonders if Kusuri's mother will be his next girlfriend, but she isn’t.
  • Boyfriend-Blocking Dad: Played with for Kusuri's Dad. He actually is open to Rentarou dating Kusuri, but only if he dumps his other girlfriends. He begrudgingly accepts Rentarou's relationship with Kusuri after Rentarou risked his life to protect her, but he's still annoyed that Rentarou is dating other girls.
  • Foreshadowing: Dad manages to pull Rentarou to his knees by grabbing the lapels of his jacket despite having the body of a child. Because he possesses Super-Strength from his own concoction of consumed drugs.
  • Genius Bruiser: They're both pharmacologists just like their daughter. Dad met his wife in a drug lab, and he's essentially a superhuman.
  • Guinea Pig Family: They both took Kusuri's immortality drug, leading them to look like 8-year-olds, but can temporarily revert to their normal appearances with the neutralizer. It's also implied that they test experimental drugs on themselves as well.
  • Happily Married: Mom casually mentions she got the soulmate Zing when her eyes first met Dad's, which brings up hearts for both of them.
  • Idiot Hair: Kusuri inherited both of hers from each of them. Mom's is the shortest.
  • Immune to Bullets: As a result of his augmentations, bullets annoy Dad at best.
  • Knuckle Cracking: Dad does this when meeting Rentarou for the first time.
  • Magic Pants: The size of Dad's natural form is too big for his child-sized clothes to bear... but he still keeps his underwear.
  • May–December Romance: Subverted. Mom is 55 years old, and first-year high-schooler Rentarou thought she would be one of his soulmates, but she isn't.
  • The Mind Is a Plaything of the Body: Defied, according to Yaku; their brains have finished developing, so they're not subject to this, but Kusuri's hasn't, so she is.
  • Nice Girl: Mom is welcoming to Rentarou upon meeting him. Despite knowing he has 14 other girlfriends.
  • Older Than They Look: They both took Kusuri's failed Immortality Drug, thus they're in the bodies of 8-year-olds as well. Mom is actually 55. Even after being hit with the Negation Drug, she still looks like she's in her early middle-age.
  • Open-Minded Parent: Unlike Dad (At first. Sort of...), Mom has no problem with Rentarou being a 15-timer.
  • Shared Family Quirks: Like her daughter, Mom's default expression is a Playful Cat Smile.
  • Shipping Torpedo: Played With. Dad can actually accept Rentarou as Kusuri's boyfriend… as long as he ditches his other girlfriends and devotes himself solely to Kusuri. After Rentarou tries turning himself into a Human Shield to protect Kusuri though, he stops demanding Rentarou dump his other girlfriends, even if he still doesn't like it.
  • Ship-to-Ship Combat: In-Universe. He argues with Uncle Hiro over whether Kusuri or Chiyo is the cutest girl in the world.
  • Super-Strength: Dad augmented himself with a whole bunch of enhancements. His adult form is basically the Hulk. A less muscular Hulk, but still one that can punch a man flying through the roof.
  • Tsundere: After Rentarou proves how important Kusuri is to him, Dad accepts him for the most part but still acts standoffish with him, such as snapping at him when Rentarou calls him "father-in-law". He does come to care about Rentarou though, being just as concerned as everyone else when he succumbs to fatigue during the Quad Town Public Sports Festival.
  • Unnamed Parent: They literally introduced themselves as Mom and Dad.
  • Verbal Tic: Mom says "Mm-hm"note  and Dad says "Uh-huh".note 

    Old Man Yakuzen 
https://static.tvtropes.org/pmwiki/pub/images/100gf_old_man_yakusen.jpg

Kusuri's deceased grandfather and Yaku's first husband, a soldier she met in a warzone.


  • Cannot Spit It Out: He was never even able to say "thank you" to Yaku, as evident by him carving a message in English on the underside of a vase he made for her, knowing she couldn't understand English.
  • Eye-Obscuring Hat: In the one picture we have of him, the top half of his face is in shadow from the visor of his hat.
  • Hidden Depths: He had a better grasp of English than Yaku, though that's a very low bar. He also had a knack for pottery.
  • Manly Man: In Yaku's eyes, at least.
  • Noodle Incident: The war where he met Yaku.
  • Posthumous Character: He's already dead by the time Yaku meets Rentarou. Whether he died of old age or in battle is never established.
  • Reincarnation Romance: It's implied that he reincarnated as Rentarou, which is why Yaku was one of Rentarou's soulmates, why Rentarou is able to visualize Yaku's adult form despite having never seen it, and why Rentarou is instinctively able to understand the meaning behind the vase he gifted Yaku despite the only thing Rentarou had to go on about the man being that he was "taciturn".
  • The Stoic: By Yaku's description, quite taciturn and awkward in certain ways. He thought expressing love with words was foolish (though Rentarou interprets it as him being too shy to express his feelings).
  • Unnamed Parent: Only known as 'Granddad' or 'Grandfather'.

    The Meido Couple 
Mei's biological mother and father, who abandoned her as a child and have never been seen since.
  • Abusive Parents: They are so abusive all mention of them was relegated to bonus chapters because it was too bleak for the main manga. They were deep in debt and abandoned Mei because of it, which would have led to her death if not for Hahari rescuing her. Whatever they put her through, she came out the other end with her self-esteem almost completely obliterated, believing her life had no value, and with no idea what "playing" was. Mei's brief comment on how a cucumber would be a feast for her before she met Hahari implies the parents either starved her or neglected to cook for her.
  • The Ghost: Unlike other family members for girlfriends who get flashback chapters, they're not shown or heard from.
  • Hate Sink: Despite their lack of onscreen presence, the Meido parents are one of the only families of a girlfriend to be cast in a purely negative light, being the ones responsible for Mei's subservient personality. From what little is said about them, they were horribly abusive towards their daughter to the point of abandoning her just to save themselves from debt, leaving her with severe self-esteem issues and no value on her own life. The circumstances of Mei's past are unusually dark for the main story, such that both parents are only mentioned in bonus chapters.
  • I Have No Son!: Any familial connection between them and Mei died when the couple left Mei to her fate all so they can save their own skins.
  • Karma Houdini: As far as Rentaro's Family knows, neither of them faced any punishment for their abuse and abandonment of Mei.
  • Small Role, Big Impact: Despite not appearing at all and being only mentioned, their abuse and abandonment of Mei is the primary reason she is in Hahari's service and is an Extreme Doormat.

    Ikuya Sutou 
https://static.tvtropes.org/pmwiki/pub/images/ikusbrother.png

Iku's older brother, who got her into sports.


  • Only Sane Man: Implied. Leaving aside their parents, who we know little about, it initially seemed like Iku was the only member of the family to have any eccentricities. Then "The Serious Group" is introduced and revealed to be headed by a relative of Iku's, and it suddenly looks more like Ikuya is the only one in his family with his head screwed on tight.
  • Unwitting Instigator of Doom: He tried teaching Iku "no pain, no gain," that is, that improvement can't come without some degree of discomfort. She took pain = gain and gain = good, and ended up with pain = good, becoming the unrivaled masochist she is today.

    Mr. and Mrs. Kakure 
https://static.tvtropes.org/pmwiki/pub/images/kakureparents.png

Meme's mother and father.


  • Good Parents: In contrast to the families of some of the other girlfriends, the volume 6 extras show that Meme's parents are perfectly nice people who love their daughter and accept her quirks - even if she did (and still does) send them into a panic the first time she did her Ninja Log trick.
  • Parents as People: They dearly love their daughter, but having her vanish in front of their eyes as a baby leaving them searching for her in terror for an hour clearly left its mark on them. Even in the present when she's old enough to take care of herself, Meme vanishing unexpectedly will send them into a panic.

    Hiro Iin 
https://static.tvtropes.org/pmwiki/pub/images/hiro_6.png

Rentarou's somewhat overbearing uncle. Rentarou saved his life once, causing Hiro to revere him and eventually try setting him up with his daughter, Chiyo.


  • Amazingly Embarrassing Parents: Chiyo isn't thrilled with many of her father's attempts to push her and Rentarou closer together, or make her his number #1 girlfriend.
  • Animals Hate Him: Hiro claims that every dog he's ever met has bitten him. His fear seems to have merit since the dog he and Chiyo adopted in Chapter 199 keeps biting him. Chiyo even notes in Chapter 225 that, while Wantarou doesn't normally bite people, he always bites Hiro when given the opportunity.
  • Art Evolution: Much like his daughter, his character design undergoes a subtle shift as the series continues, gaining more detailed features like Exhausted Eye Bags and a squarer jaw.
  • Bumbling Dad: Hiro is emotional, easily scared, and prone to making Zany Schemes, compared to his daughter being fairly calm and sensible.
  • The Chessmaster: The hijinks that ensued from Rentarou coming to babysit Chiyo, from the stray marble that causes a Crash-Into Hello to Chiyo's glasses flying off, were entirely orchestrated by him so that the two of them would fall in love.
  • Control Freak: A... very odd and downplayed example. Hiro's standards for who gets to date his daughter are impossibly high, and to that end, he will only allow Rentarou to do so. Other than that, he lets Chiyo do what she wants.
  • Crossdresser: While planning out Chiyo and Rentarou's date at the theme park in the volume 15 extras, he put himself in Chiyo's role, to the point of wearing a feminine outfit, and had a life-sized stuffed Rentarou doll in Rentarou's role.
  • Dads Can't Cook: He does try cooking, it's just that it never tastes good, so Chiyo takes it upon herself to do it instead.
  • A Day in the Limelight: The fittingly titled Chapter 199, "The Dog, the Daughter, and the Dad", focuses on him just as much as it does Chiyo, particularly highlighting how much Chiyo doesn't want to inconvenience him after she finds an abandoned puppy and fearing his cynophobia will be triggered, while in turn highlighting his genuine love and care for Chiyo to the point of undergoing exposure therapy just so she can keep the puppy.
  • Doting Parent:
    • When all the girls were hosting a public concert, Hiro did the same Zany Scheme as Rentarou, making puppet versions of himself to increase the audience size for Chiyo's sake.
    • When Chiyo invites Matsuri and Eru over for a sleepover, he splurges a bit and buys enough cake for all of them to have their pick without having to argue over who gets what. When Chiyo is understandably annoyed over the idea Hiro went over their monthly budget doing this, he quickly reassures her that he bought the cakes using his own personal allowance rather than the family budget.
  • Everyone Has Standards: Highly downplayed. Even though he'd been planning on setting Chiyo up with Rentarou for years beforehand, he wanted to avoid aspects like the two seeing each other as Like Brother and Sister and wanting Chiyo to be old enough to be in a relationship, hence his preventing the two from meeting for years. After seeing Rentarou routinely joined by a steadily increasing number of girls however, he panics and decides he can't afford to wait any longer lest Rentarou not "choose" Chiyo, so he orchestrates their first meeting several years ahead of schedule.
  • Face Your Fears: In Chapter 199, Hiro tries to conquer his fear of dogs so Chiyo can adopt a puppy he found. He's still pretty scared of the dog since it frequently bites him, but he's at least willing to stomach his fear for her sake.
  • invoked Incest Yay Shipping: He doesn't care at all that Chiyo and Rentarou are cousins.
  • I Owe You My Life: His bottomless respect for Rentarou stems from his nephew pushing him out of the way of a tanker truck as a child.
  • I Want Grandkids: He expresses a desire for grandchildren in one of the extras for Volume 7.
  • Long Game: His master plan involved not letting Rentarou and Chiyo meet until more than a decade had passed, in order to prevent them from thinking of each other Like Brother and Sister. He originally wanted to wait longer than he did, but began to panic after seeing Rentarou with eleven girlfriends and not being aware of their relationship being polyamorous, so he rushed the time table and had Rentarou and Chiyo meet several years early.
  • Lovable Coward: Hiro is so cowardly that he clings to Chiyo for comfort from a scary movie ad, but he's also a loving and doting father.
  • Made of Iron: He gets hit by another tanker truck while on his way to help Rentarou with the girls' idol performance. It only slows him down; Chiyo is performing and nothing's going to stop him from being there.
  • Obliquely Obfuscated Occupation: For a long time it was often noted that he does have a job of some kind which is why Chiyo often had to do things like shopping for them, but it was unclear what he actually did since he seemed to only ever spend time doting on Chiyo or acting as a Shipper on Deck for her and Rentarou. It wouldn't be until Chapter 199 that his job would be even referenced, and only via a notation clarifying what he was actually doing when he otherwise looked to just be websurfing: he's a web designer, allowing him to work from home and explaining how he can be able to dote on Chiyo so much.
  • Parents as People: For as much of a Bumbling Dad he can be, Hiro makes clear that Chiyo is the most important person in his life, and is willing to do what he can to be a supportive parent for her. This extends to even working to move past his near-crippling cynophobia once he realizes how attached Chiyo has become to an abandoned puppy, acting much more maturely while reassuring her that it's okay for her to rely on him.
    Hiro: I'm sorry. I know what kind of man I am. Not someone you can count on... But... I want you to be able to rely on me. Because I'm your dad. Whatever you want, Chiyo, I'll hear you out. — You kept quiet because you didn't want to stress me out... but it's alright Chiyo. The last thing I'd want is for you to worry about me.
  • Ridiculously High Relationship Standards: Hiro's standards for who gets to date his daughter are impossibly high, and to that end, he will only allow his nephew, Rentarou, to do so. For context, Hiro is so grateful for Rentarou saving him from being hit by a tanker truck as a young boy that he resolved to set him and his daughter up as lovers when she was old enough. However, he set his master plan into action early when he noticed a steadily increasing number of girls accompanying Rentarou to school.
  • Shared Family Quirks: Starts bawling his eyes out just like his daughter while begging Rentarou to date her. It's also shown that he and Rentarou share a lot of behavior such as going to extremes for their loved ones but viewing it as normal.
  • Shipper on Deck: For Chiyo and Rentarou, to a truly ridiculous extent. Rentarou can count on him for help if he ever needs to pull off something really elaborate.
  • Ship-to-Ship Combat: In-Universe. He argues with Kusuri's dad over whether Kusuri or Chiyo is the cutest girl in the world.
  • Uniformity Exception: Aside from Hahari, Hiro is the only parent of a girlfriend to appear regularly and have a relationship with someone outside of being a girlfriend's parent, namely his relationship with Rentarou and rivalry with Kusuri's dad, even sharing A Day in the Limelight with Chiyo in Chapter 199.
  • Wacky Parent, Serious Child: Hiro makes wacky schemes and calls Chiyo for help when he's scared, while Chiyo is more serious and mature.
  • Why Did It Have to Be Snakes?:
    • He's terrified of stinkbugs.
    • Similarly, dogs. Every dog he's ever met has bit him, including one traumatizing case where he was almost killed by a chihuahua biting his carotid artery. He's able to get over it via Rentarou-assisted exposure therapy for the sake of a puppy Chiyo adopts, although the puppy still treats him like a chew toy.

    The Yamato Family 
Naddy's, or rather Nadeshiko's, upper-class family.
  • Abusive Parents: They are nothing but strict and controlling to Nadeshiko, forcing her to abide by their customs every day. At one point, they threw Nadeshiko in the warehouse because she couldn't play the koto. When Nadeshiko began to embrace American culture, her parents regarded her as a disgrace to both their name and Japan before kicking her out.
  • Ambiguous Situation: Chapter 219 invites some questions about the Yamato family that aren't answered by the end.
    • The nightmare version of Naddy's mother refers to the Yamato family as having a "2000-year long legacy". Assuming this isn't just an oddity from Naddy's dream, that would suggest the Yamato family is the same as the Yamato clan, the first and only dynasty to rule Japan. That would in turn suggest that Naddy isn't just a former upper-class heiress, she's technically a Fallen Princess.
    • The end of the chapter reveals that Naddy’s pillow stuffing had been switched out for stuffing from the Yamato household to induce guilt tripping nightmares so that Naddy would return to her old home. Who exactly is responsible for switching them and for what reason they've been doing so, whether out of remorse or to purge Naddy of her "corruption", is unclear.
  • Fantasy-Forbidding Father: They heavily disapproved of Naddy's Foreign Culture Fetish and eventually kicked her out and disowned her when she refused to abandon it.
  • The Ghost: It’s mentioned that Naddy has a younger sister, who is later revealed to have been thrust into Naddy’s old position after she left.
  • Hate Sink: The Yamato parents are one of the only families of a girlfriend to be cast in a purely negative light, Naddy's time under them being restrictive and miserable. Their kicking Naddy out was ultimately the best thing they did for her since it freed her from their influence, and allowed her to say "fakkyuu" and be on her way to live her life, the narrative making clear in no uncertain terms that Naddy being free of them is a good thing. While this initially applied for the entire family, the notion that Naddy has a little sister who has yet to appear but Naddy fears is suffering the same kind of abuse she went through made it clear, at least so far, that the parents are the loathsome ones of the family.
  • Hypocrite: A young Naddy notes that when they threw her into the warehouse, they slammed the door hard enough that it knocked things off the shelves, but scolded her if she wasn't gentle in handling doors.
  • Ninja: Apparently have ninja working for them.
  • Spare to the Throne: As the eldest daughter, Nadeshiko was the one expected to inherit the Yamato household and was the one her parents trained rigorously. After she refused to let them make her miserable any more and they disowned her, the role fell to Naddy's younger sister. Chapter 219 shows that, subconsciously at least, Naddy fears what her sister might be suffering through on her own all because of her leaving and regrets doing so. It's all but said the "regret" is a result of the Yamato household inducing guilt-tripping nightmares in an attempt to force Naddy to come home, and while the motive behind their doing so is unclear, one possibility is the attempt at subverting the trope by making Naddy retake the position of heiress.
  • Unseen No More: The only one of Nadeshiko's relatives to be seen is her mother, who was only heard from off-screen until Chapter 219, though even then her eyes are still cast in shadows.
  • Yamato Nadeshiko: The aesthetic they cultivate, and what they wanted Nadeshiko to be, to the point that their family name is Yamato and they picked her given name to complete the phrase.

    Mr. and Mrs. Yasashiki 
Yamame's mother and father.
  • Good Parents: Yamame's father does his best to make sure his daughter doesn't have to put up with Height Angst. He can't protect her from everything, but he'll come down hard if he sees someone bad-mouthing tall women.
  • Hypno Pendulum: Yamame's father uses one to hypnotize her and help her deal with the guilt of crushing a bug... by making her think the bug came back the size of a person to tell her that he went to heaven.

    The Torotoro Family 
https://static.tvtropes.org/pmwiki/pub/images/kishikafamily.png

Kishika's mother and five younger siblings.


  • Ambiguously Absent Parent: We only ever see Kishika's mom in the flashback; the only mention of her father is a casual reference to her parents and siblings relying on her, implying he's at least around, but that's all.
  • Massive Numbered Siblings: Six of them, including Kishika.
  • Parents as People: Her mother is still present in her life, but is so busy working to support six children that much of the actual parenting is left to Kishika, something that she regrets immensely.
  • Shared Family Quirks: Not quite the same quirk, but complementary ones. Her mother wants to pamper Kishika like she's a little girl but believes she's too mature now and would reject such attention. Kishika meanwhile wants to be pampered but doesn't think her mom would do it if she asked.

    Mr. and Mrs. Kedarui 
https://static.tvtropes.org/pmwiki/pub/images/kedaruiparents.png

Ahko's parents.


    Grandma Meido 
https://static.tvtropes.org/pmwiki/pub/images/grandmameido.png

Mai’s grandmother, who once served as the head maid of the Hanazono household.


  • Ascended Extra: She has brief non-speaking appearances in flashbacks during Mai's introduction in Chapters 101-102, then a speaking part and a more detailed appearance in Chapter 170 as Mai has to prove herself to her to stay with the family.
  • Distinctive Appearances: Like Mai, her hair shades between colors, going from lighter to darker.
  • Family Honor: One of her concerns after Mai accidentally signs up for a bunny girl exam instead of a maid exam is Mai not bringing (more) shame to the family name.
  • Hidden Depths: While she presents as the stern and strict type, she's perceptive and understanding, seeing what Momoha's doing to support Mai.
  • Meido: Being a maid is the Meido Family Business; they've been at it long enough they have customs for the qualification process.

    Mr. and Mrs. Bonnouji 
Momoha's parents, proprietors of Bonnouji's Brewhouse. First mentioned in Chapter 108, they appear in flashback in Volume 13's bonus chapter, before appearing in the series proper in Chapter 229.
  • Call-Back: The flower-scented sake that they created for (and named after) their daughter is one of the products for sale at their brewery. Rentarou helps them deal with their financial troubles by advertising that brew to younger adults.
  • Disappointed in You: They’re not particularly pleased about their daughter’s lifestyle, especially when they find out that she’s dating a student at the school where she works. At least they don't know about the harem yet...
  • Mundane Solution: Relatively mundane, anyway: Rentarou proposes they record a commercial for Momoha sake to appeal to younger adults, and he (as of that chapter) has the basics of video editing down pat. It works extremely well.
  • Support Your Parents: Played with. When she lived with them, Momoha gave them significant financial support; They kicked her out because they thought this was holding her back and wanted her to be independent and live her own life. Even now, despite being addicted to gambling, booze, and just about anything else she can get her hands on, she sends them most of her paycheck before blowing the rest on vices. In Chapter 229, it even extends to her considering quitting her job as a teacher so she can do this, even though she knows they wouldn't approve.

    Mr. and Mrs. Baio 
https://static.tvtropes.org/pmwiki/pub/images/baioparents.png

Rin's parents.


  • Elegant Classical Musician: According to Rin, both of them are violinists and started her lessons early.
  • Fantasy-Forbidding Father: Played with. Mr. Baio tried to dampen Rin's sadistic tendencies by sheltering her from violence, but this was largely when she was too young to really understand it herself, and in the present Rin's not actually aware he knows about her sadism and was trying to repress it.
  • Parents as People: Mr. Baio loves his daughter, sadism and all. But he worries about the rejection and ostracization she'll face for it, and as a result has tried to raise her in a sheltered environment that exposes her to as little violence as possible, hoping to give her a better chance in life even though he's not happy about denying a part of her personality.

    Mrs. Hifumi 
https://static.tvtropes.org/pmwiki/pub/images/mrshifumi.png

Suu's mother.


  • Good Parents: When little Suu starts bawling her head off at being parted from the numbers on the kindergarten's victory podium, her mother is surprised to see her crying, and asks the kindergarten if they can take the podium home with them so Suu won't have to be parted from it.
  • Open-Minded Parent: She may not quite get Suu's particular brand of weirdness, but she doesn't seem to mind it.
  • Strong Family Resemblance: Her daughter will grow up to look almost exactly like her.

    Mr. and Mrs. Kaho 
https://static.tvtropes.org/pmwiki/pub/images/eiraparents.png

Eira's parents. Her dad runs a capoeira dojo.


  • Forehead of Doom: Eira's mom has a prominent forehead.
  • Good Parents: Eira's parents advised her to go to college so she could have more options and learn more about the world.
  • Implausible Hair Color: Eira looks to have got her silver hair from her mom.
  • Kick Chick: Gender inverted. Eira's dad is a capoeirista and brought Eira up to be one too.
  • Parents as People: Mr. Kaho wanted to stop his daughter from being a Fearless Fool who thinks Violence Is the Only Option, especially after learning she jumped into a river the day after a rain storm just to get her friend's hat thinking she could beat a cold away, but his choice to scare her by pretending to be a ghost and demonstrating she can't beat up everything just turned her into a Nervous Wreck that freaks out when she can't beat something up.
  • Unwitting Instigator of Doom: Her dad's attempt to teach Eira to properly appreciate fear caused her to go from being a Fearless Fool to a Nervous Wreck terrified of anything she can't take down.

    Mrs. Nekonari 
https://static.tvtropes.org/pmwiki/pub/images/tamasmom.png

Tama's mother.


  • Fantasy-Forbidding Father: Technically. She doesn't approve of Tama's desire not to work, but all the advice she gives Tama on the matter is pretty run-of-the-mill advice for a parent to give their child. Notably, Tama herself comes to decide that it's unfeasible to live completely as a cat, independently of her mother's advice.
  • Parents as People: Her advice for Tama is well-intentioned, but the problem is she doesn't realize how serious her daughter's psychological issues are.
  • The Voice: She's only heard on the phone during Tama's introduction, getting her first appearance in Volume 17's bonus chapter.
  • Wrong Assumption: When Tama phones her mother in the Volume 17 extras to tell her she's changed jobs and found a lot of friends, her mother assumes it means Tama's ready to face reality when what it actually means is that Tama's met people who accept her issues and a part-time job that asks far less of her than your average 9-to-5note .

The Vice-Principal of Ohananomitsu, a grotesque-faced former jack-of-all-trades Olympian athlete heavily implied to not be human.


  • Abhorrent Admirer: She tried to kiss Rentarou once for running in the hall, and even though Rentarou was planning this so that his Sacred First Kiss won't be given to just one girlfriend, he's still terrified when she actually catches up to him.
  • Ambiguously Human:
    • Given her Overly Long Tongue, Wall Crawling, and incredible athletic ability, Rentarou questions if the Vice-Principal is even human.
    • During the Kiss Zombie arc, when Kusuri melts her makeup off, the official translations have her angrily complain about her true form being revealed to "the humans".
  • Ax-Crazy: She is insane. The only thing she cares about in life is getting to kiss attractive young men for as long as she wants, and won't let anyone get in her way, easily resorting to violence if they try. Not even being faced down by "Poseidon" [read:Rentarou in the mouth of a shark with seaweed covering his face], who she thinks is a literal god, will deter her, it taking a literal whale eating her to get her away from the Rentarou Family. And she still somehow came back!
  • Black Comedy Rape: Less actual rape, but her behavior towards her students is for all intents and purposes sexual assault, yet its played for dark cringe comedy.
  • Dean Bitterman: In her debut, Hakari and Karane mention that her main job is to hunt down students breaking the rules (especially running in the halls). This aspect rarely comes up in later chapters, even if the mains are breaking school rules left and right. One supposes it's used when it would be funniest.
  • Dirty Old Woman: Her hobby is kissing young men, and she especially wants one from host clubs. She also likes to take the "Lost and Found" box around the school and steal schoolboys' personal belongings.
  • The Dreaded: All the boys at school fear getting kissed by her.
  • Everyone Calls Him "Barkeep": Aside from the bouquet-tossing contest, she's almost always referred to as the Vice-Principal.
  • Evil Counterpart: She’s effectively an embodiment of every negative personality trait that Rentarou lacks, and makes Hahari look like a nun by comparison. Not only is she highly aggressive about satisfying her own lust, but she pretty much always goes out of her way to ruin other people’s days if not their lives, a stark contrast to the former being devoted to making his girlfriends' lives better and even helping out strangers to no benefit for himself, and the latter having numerous lines she won't cross while genuinely loving the Rentarou Family.
  • Fan Disservice: Aside from her face and long-shaped breasts, she has stereotypical sexy traits. But there's absolutely nothing sexy about the first two.
  • Forceful Kiss: Exaggerated. When she catches a student running in her halls, she pins them to the ground and rams her Overly Long Tongue down their throat.
  • Funny Afro: And it's large enough that Meme can hide inside it without arousing suspicion.
  • Getting Eaten Is Harmless: She gets Swallowed Whole by a whale on Poseidon's orders at the end of Chapter 210, but escapes by the next day.
  • Gonk: She's very ugly, and that's just wearing make-up. Her real face is implied to be even uglier.
  • Hate Sink: Even with her antics played for Black Comedy, there is absolutely nothing sympathetic about her, her gonkish design and Dirty Old Woman behavior is repugnant, and any physical punishment she suffers is entirely deserved.
  • Insane Troll Logic: Taking inspiration from Japanese legends about how eating mermaid flesh can grant someone eternal youth, she decides to visit the aquarium hoping to find some mermaids to steal, thinking she can find them with some dowsing rods. Despite Rentarou trying to tell her there are no actual mermaids there and the only ones present are himself and the rest of the Rentarou Family having rented the aquarium out, she refuses to listen, knocks Rentarou out, and then kidnaps the rest of the family with the intent of eating them thinking they're mermaids due to wearing costumes. This is despite the fact a third of them are dressed like sea animals rather than mermaids like five dressed as penguins or Saki as a manta ray, while the "mermaids" are obviously her students and boss in costumes, she refuses to believe anything aside from the idea they're mermaids, grabs girls dressed like sea animals "to be safe", and tries to swim out to the middle of the ocean so she can eat them one by one where no one can get in her way.
  • Karma Houdini: Though she gets the occasional Laser-Guided Karma for her behavior, she has thus far avoided legal troubles for all the emotional trauma she consistently inflicts on students. Hahari briefly considers firing her in Chapter 46, but nothing comes of it. Not even kidnapping her chairwoman and many of her students (with the stated intention of eating them) in Chapter 210 gets her fired.
  • Nice Job Fixing It, Villain!: In Chapter 204, giving Mentarou Ike one of her forced French kisses traumatized him to the point of never wanting to even see another pair of panties for the rest of his life.
  • Opaque Lenses: Her shades would probably look cool on someone else. Seeing what one of her eyes looks like underneath doesn't exactly instill any desire to see the other.
  • Overly Long Tongue: Her tongue was already pretty long in her earlier appearances, and it's only gotten longer as the series progressed, to the point where it's now about as long as her head.
  • Super-Speed: She uses it to catch men for kisses. She used to be a track-and-field athlete where she was nicknamed, depending on the translation, "The Hag Closest to Supersonic Speeds in this World", "Sonic the Sketchhag," or "Sonic the Hedgehag".
  • Super-Strength. In Chapter 210, she traps Rentarou's 32 girlfriends on a massive net and drags them alongside her while swimming at her usual Super-Speed without breaking a sweat.
  • Ultimate Job Security: Even though it's well known that she forcibly kisses male students, she somehow manages to keep her job. Hahari does briefly consider firing her in Chapter 46, but nothing comes out of it. This gets exaggerated after Chapter 210, wherein she commits aggravated assault on Rentarou and proceeds to kidnap the entire Rentarou Family aside from him due to thinking they're mermaids, Hahari included, and yet she isn't somehow fired or arrested after that.
  • Vocal Dissonance: In the English dub, she speaks in a raspy, masculine voice pretending to sound like a woman, reflecting her ugly and inhuman appearance.
  • Wall Crawl: She's shown crawling on walls in Chapter 150 of the manga and Episode 2 of the anime.
  • Would Hurt a Child: Even outside of her sexually assaulting her students, she has no issue striking Rentarou with the intent of knocking him out so he can't stop her from getting to the "mermaids", proceeding to then kidnap the rest of the Rentarou Family with the intent of eating them. Rentarou lampshades the fact she, an educator, would actually strike one of her students in the modern day and how it caught him off guard, but that he won't let it happen again and will kill her if she so much as harms a hair on one of his girlfriends.

    The Stray Cat 
https://static.tvtropes.org/pmwiki/pub/images/the_stray_cat.png

A seemingly ordinary all-white cat that lives on the school roof, a background character that is frequently shown overlooking and sometimes joining in the interactions of the Rentarou Family.


  • Deadly Dodging: Something like this in Chapter 28, when Kusuri tries to lighten a tense mood when she sees the cat by throwing a test tube and telling the cat to fetch it. The cat instead dodges, leading to its contents, the newly created babyfication medicine, enveloping everyone but Rentarou and Hakari.
  • Screw This, I'm Outta Here!: In Episode 4, at seeing the rising tension between Karane and Shizuka when Rentarou leaves the rooftop, the cat gives a full-body shudder and scrams.
  • Spanner in the Works: In Episode 2, during take two of Rentarou's First Kiss experiment, the cat is enchanted by the laces on Karane's panties and comes over to paw at them. Karane, unable to see or hear, assumes it's Rentarou and lashes out at him; she only hears the cat when her headphones fall out.

    Fumi Utsushiro 
https://static.tvtropes.org/pmwiki/pub/images/fumi_utsushiro.png

A senior Japanese teacher at Rentarou's school who sees Naddy as a bad influence on her students.


  • Jerkass Has a Point: She does make a valid argument that not everyone understands Naddy as well as Rentarou, and he shouldn't expect people to be as perceptive as him. Then it's subverted when it turns out that Naddy's odd way of speaking was improving her students' grades because it made her class more interesting and forced them to concentrate harder to decipher what she was saying.
  • Simple Solution Won't Work: She isn't one of Rentarou's soulmates, so he can't resolve the issue by having her fall in love with him as Hahari did.
  • Stern Teacher: She believes Naddy's confusing mannerisms would cause trouble for students.

    Toruru Kijineta 
https://static.tvtropes.org/pmwiki/pub/images/toruru_kijineta.png

The head of Ohananomitsu's newspaper club, who attempts to write about Meme in their paper and won't take "no" for an answer.


  • Accidental Misnaming: The victim of it, as Mimimi can't seem to remember her name even when she's just re-introduced herself. As shown in the volume 7 extras, neither can Hahari.
  • Bit Character: Thus far, she's only appeared in one chapter to cause Meme stress.
  • Blackmail: Her answer to Hahari trying to shut down her stalking of Meme is to threaten to leak photos of the chairwoman's antics with the harem (including her own daughter), pointing out just how much hot water everyone would be in if she blew the whistle. Not to say that she was trying to blackmail Hahari, of course.
  • Camera Fiend: Naturally, as a member of the newspaper club. She rigorously trained in the art of photography to the point that she could snap a picture of Meme mid-Ninja Log.
  • Catchphrase: "Hellohellohello!"
  • Everyone Has Standards: While she claims to follow journalistic ethics when reporting, she only does so by adhering to Exact Words, such as loudly announcing herself so she can justify taking pictures of people since she's not allowed to take pictures of people without their knowledge. She does it so abruptly though that it doesn't give people any chance to react, and doesn't particularly care about the fact she's harassing Meme in the process, caring only for getting her scoop. She also has no issue resorting to blackmailing Hahari, the head of the school board, when she justifiably tries telling Toruru to knock if off, which is a rather blatant breach of journalistic ethics.
  • I Know Mortal Kombat: Learned the art of "Total Concentration: Reporter Breathing" while covering "a certain recent, trending topic."
  • In the Blood: Toruru mentions that her father works in the media, though not specifically where.
  • Intrepid Reporter: After deciding to write about the elusive Meme in the paper, Toruru refuses to give up on getting a photo of her face to go alongside the story.
  • Red Herring: She's given a full name, a full backstory, and her Blackmail photos of Hahari's amorous interactions with the students are unknown to Rentarou despite appearing in them. These all suggest she might be a soulmate at some point, but so far, nothing has come of that.
  • Wrong Genre Savvy: Toruru acts as if she is an Intrepid Reporter in a much more serious work, down to even using blackmail on Hahari over how society would react to the Rentarou Family while acting as if she were The Chessmaster in this situation. She not only fails to see that the setting is a romantic comedy with practically No Fourth Wall and an absurdist sense of humor, but that Hahari also has a large amount of money to her name and thus is more than capable of doing something about the blackmail and that Rentarou is insanely protective of his girlfriends and had to be talked down from burning her club to the ground originally, meaning even if she had tried to go through with the blackmail, it more than likely would have failed and just earned her Rentarou's hate.

    Mentarou Ike 
https://static.tvtropes.org/pmwiki/pub/images/image_3131.png

A panty snatcher whose latest crime attracts the attention of Hasuha Hasu.


  • Bitch in Sheep's Clothing: When the girl whose panties he stole asks him if he's seen them, he offers to give her his own pants instead, causing the girl to immediately assumes he's innocent just because of that nice gesture. Upon being outed, he becomes much more aggressive.
  • Covert Pervert: He presents himself as a normal student, and internally panics at the possibility of his obsession with girls' underwear being exposed to the public.
  • Didn't Think This Through: He's a rather incompetent pervert. First, he offers to give his own pants to the girl whose underwear he stole, even though he was hiding them in his pant pockets. Then, upon being exposed, he runs off, having forgotten what happens to students who run in the halls. This gets him caught by the vice-principal very quickly.
  • Evil Counterpart: To Rentarou. Both have similar names and appearances, but Rentarou is an open and love-obsessed Nice Guy with a family of girlfriends whom he cherishes and would rather die than hurt or humiliate them, while Mentarou is a panty-obsessed Covert Pervert who makes a habit out of pilfering girls' underwear and who pushes Hasuha out of his way when he gets caught.
  • Kick the Dog: Or "Push the Dog". When Hasuha exposes him as the thief, he pushes her aside and runs off. Luckily, Rentarou catches her before she gets hurt.
  • Meaningful Name: His full name is a play on two words Ikemen (イケメン ikemen) and Tarou (太郎 tarō). When combined, it literally means Handsome Big Boy.
  • Panty Thief: Mentarou had a nasty obsession with girls' underwear, and always jumped at the chance to steal them. He kept this habit a secret until he was exposed by Hasuha Hasu and forcibly reformed by the vice-principal.
  • Rape Portrayed as Redemption: A more tame example. When he starts running through the hallways, the vice-principal catches him and forcibly kisses him like she usually does. The narrator then remarks that he flashed back to that moment whenever he saw panties again, so he'd go to live an honest life from then on.

Others

    Agent One-Double-Oh-KH (Unmarked Spoilers
https://static.tvtropes.org/pmwiki/pub/images/agentonedoubleohkh.png

A small alien Yamame finds injured in the woods, they bond with the Rentarou Family after Yamame patches them up. They're actually an advance scout sent by their home in preparation for their species' invasion of Earth, pretending to be helpless due to their injuries and intending on backstabbing Yamame once the opportunity presented itself, only to change their mind because of the family's kindness.


  • Aliens Speaking English: Subverted. Their species has their own language, but they manage to pick up Japanese as a result of listening to the Rentarou Family talk. This also causes them to pick up the mannerisms of the Rentarou Family and blend them all together, one minute acting like a tsundere like Karane, the next using overly flowery language like Uto.
  • Ambiguous Gender: Their gender, if they even have one, is unknown, as they're only ever referred to as "it" or with gender neutral pronouns.
  • Because You Were Nice to Me: After being helped by Yamame and bonding with the Rentarou Family, they decide against the original plan to invade the Earth since it would mean their friends being caught up in it. Instead, they introduce "kissy wissy" to their species and convince their ruler to leave Earth alone.
  • The Farmer and the Viper: Subverted. They initially intended on scouting the Earth in preparation for an invasion, only for their ship to crash and Yamame to find them injured. Once Yamame patched them up, they planned on waiting till they were fully healed before killing her, but her and the rest of the Rentarou Family's kindness convinced them to spare them, then convince their leader to spare the Earth entirely so as to protect their newfound friends.
  • Love Freak: As a result of witnessing Hahari kissing Rentarou, Hahari teaches them about "kissy wissy" and how happy it makes you. To stop their Supreme One from invading the Earth, they proceed to give the Supreme One "kissy wissy", which they immensely enjoy, resulting in their entire species becoming addicted to kissing and leading to the invasion being called off.
  • Only Known by Their Nickname: The Rentarou Family never actually give them a name, and their ruler only refers to them by the codename "Agent One-Double-Oh-KH".
  • Ridiculously Cute Critter: Their species is very tiny, only coming up to Kusuri's ankle, causing them to look more like an alien plushie than anything. The Rentarou Family all quickly fall in love with how adorable they are.
  • Shapeshifting: They demonstrate the capacity to drastically shapeshift their body, first demonstrating this ability to Yamame by turning their arm into an long and grotesque worm monster, with it implied this is their main method of defending themselves.

    Akogare and Manesu 
https://static.tvtropes.org/pmwiki/pub/images/akogare_and_manesu.png

Two classmates from Chiyo's school who spend their afternoons smoking in the park.


  • The Bus Came Back: They reappear in Chapter 160, where they serve as judges in Chiyo and Matsuri's yakisoba challenge.
  • Cloudcuckoolander: Their... cosplaying of Chiyo could only have stemmed from this.
  • Fire-Forged Friends: Chapter 100 reveals that they now help Chiyo with her class president work.
  • It Amused Me: The Volume 9 extras reveal that their main motivation for smoking in the park was to annoy Chiyo.
  • Japanese Delinquents: They fashion themselves as these.
  • Jerk with a Heart of Gold: Even when they were pretending to be delinquents, they still showed concern for Chiyo. When Chiyo started crying, they assumed she was sick and offered her water and medicine. On days when Chiyo didn't show up, they feared she got in an accident and looked for her to see if she was okay.
  • Smoking Is Cool: They seem to think so. Though they were only using toy cigarettes instead of real ones.
  • Verbal Tic: "Bleedin' muppet" and "Bloomin' tosser". Which was really just part of their delinquent act.

    Anonymous Friend "A" 

Voiced by: Misuzu Yamada (Japanese), Brittney Karbowski (English)

https://static.tvtropes.org/pmwiki/pub/images/frienda_3_100gfs.png

Rentarou's friend up until their middle school graduation.


  • Ambiguous Gender: The anime gives them an androgynous voice (provided by a female voice actress) despite the text seemingly suggesting them to be male, and the character lacking a proper name only makes things more confusing. Notably, an Adam's apple is visible in both the manga and the anime.
  • Ambiguously Gay: As he wonders why Rentarou isn't getting any romantic luck, he starts listing off his good qualities in a way that makes Rentarou wonder if he's actually into him. Friend A doesn't actually deny it, and instead simply leaves.
  • Bit Character: "A" has yet to make another appearance in the manga after he and Rentarou graduate middle school, even during the popularity poll in Chapter 100 (in keeping with his telling Rentarou that this was the last time he'd be seeing him).
  • Brutal Honesty: When Rentarou comes to him to vent about his latest rejection, Friend A bluntly tells him that it's probably only going to get worse in High School.
  • The Generic Guy: In some translations, "Generic" is literally in his name. As he only appears for one scene, there isn't much time to flesh him out at all.
  • Irony: He tells Rentarou that his rejection streak will probably only get worse in high school. He has no idea just how wrong that claim is.
  • Jerk with a Heart of Gold: Though he's quite insensitive and sarcastic in his only scene, he and Rentarou apparently made a lot of good memories together through their time in middle school, and he recognizes all of his friends' positive qualities, even if he's taken aback by his sheer determination.
  • Mr. Exposition: The entire role of "A" is to establish that, despite being rejected 100 times, Rentarou is a great guy who is still liked by everyone (including the girls who rejected him).
  • No Name Given: Played for Laughs. His actual name is never revealed; even Rentarou only calls him Generic Friend "A", at the end of their conversation in Chapter 1. The official manga translation takes it further by having Rentarou call him "my generic, nameless friend".
  • One-Letter Name: Unless Rentarou was simply being sarcastic, "A" is apparently his actual name.
  • Satellite Character: After saying that he'll never see Rentarou again, the audience never sees him again either.
  • With Friends Like These...: In his one scene, he asks his friend who had just suffered a rejection about how many other rejections he has accumulated, and Rentarou lashes out at him for ruining all their precious memories together with his comments during their graduation ceremony.
  • You Monster!: After dubbing Rentarou "knight of passion", he retracts his statement and calls him a monster after hearing that his first confession was at 8 months old.

    Asakawa 

Voiced by: Satomi Amano

https://static.tvtropes.org/pmwiki/pub/images/asakawa_100gfs.png

The 100th girl who had rejected Rentarou after he confessed to her.


  • Bit Character: Her rejection of Rentarou in the first two pages sets up the manga.
  • Breaking Bad News Gently: She tries to do this by praising Rentarou's good qualities before turning him down, even saying that she does like him, but the actual rejection that follows this comes off as so blunt that it has the adverse effect.
  • Brutal Honesty: Her bluntness in rejecting Rentarou makes him want to throw up instead.
  • Eyes Out of Sight: Her eyes are always covered by her hair. Unless this is a stylistic choice, as her bangs aren't long enough to cover the area where her eyes should be, this means that even if she was a soulmate, she wouldn't have been able to "zing" with Rentarou.
  • False Soulmate: Rentarou tried to confess to her, but she rejected him.
  • Flat Character: All that's known about her is that she does like Rentarou's outgoingness and friendliness... but for some reason the image of him as her lover makes her feel like throwing up.
  • The Generic Girl: Of all the girls Rentarou falls for, Asakawa seems to be the most ordinary one.
  • Innocently Insensitive: In the anime, her embarrassed and flustered reaction following her Unnecessarily Cruel Rejection implies she didn't mean to come off as harsh, and she screams that she's sorry immediately afterwards.
  • Single Woman Seeks Good Man: Subverted. She initially appears drawn by Rentarou's general kindness, but alas, she wasn't meant to be his soulmate.
  • Small Role, Big Impact: Being the 100th girl who rejected Rentarou, she ends up jump-starting his journey of getting 100 girlfriends. The God of Love adding two figures to Rentarou's soulmate count also led him to be destined to experience 100 heartbreaks before he met his first soulmate.
  • Unnecessarily Cruel Rejection: She starts off her response to Rentarou’s confession by sweetly listing what she likes about him before bluntly telling him that she feels like throwing up imagining him as a boyfriend.

    The Big Cheese of the Publishing Biz 
A faceless being who intervenes to stop anyone from engaging in underage drinking.
  • Berserk Button: Underage drinking.
  • Catchphrase: "No can do."
  • The Dreaded: He confronts Rentarou and all the girls in their dreams to overrule their plans to have a pretend drinking party, and none of them can protest.
  • Media Watchdog: Shows up whenever someone is planning to engage in underage drinking.
  • Screw This, I'm Outta Here!: Confronted with Iku's one-woman paddling tournament in the volume 13 extras, he nopes out of there.

    Disgruntled Itamae 
The unnamed owner of a particular ramen shop, her life's goal is to create an eating challenge that nobody can defeat. She is the focus of Chapters 83 and 220.
  • Contrived Coincidence: Every time she comes up with a new gimmick for her eating challenge, the first customer to try it—and complete it—just so happens to be someone from the Rentarou Family with the right quirk (eg: a beyond supersize bowl is easily finished by Kurumi). How they keep showing up is rationalized by each of them bragging about the ramen shop to each other after going, but there's no such reasoning for the timing of who shows up.
  • Cordon Bleugh Chef: Most of her challenges have ingredients that do not go with ramen. This is especially notable with the "Damn Dummy-DumDum Idiot Ramen", which has Pocky sticks, a cheeseburger and ice cream in it. Despite the wackiness, the girls who are able to finish their ramen don't complain about the taste, implying that it is still both palatable and delicious.
  • Didn't Think This Through: In her zeal to create a challenge that can't be beaten, she tends to ignore common sense in the process.
    • Each of her challenges have the stipulation that, if the customer can complete the challenge, the customer doesn't have to pay for their meal. While the initial challenges are normalish and at the price of a normal bowl of ramen and therefore negligible in terms of profit loss from completing the challenge, as the challenges get more bizarre the cost of making the challenges far outweighs the price of the bowl, which results in the shop receiving a net loss with each challenge won. Even were she to actually create a challenge no one could beat, the amount of money she sank into doing so would be impossible to financially recover from, something she realizes too late as she mentions in Chapter 220 that the events of Chapter 83 put her into bankruptcy.
    • For the "Rich Idiot Ramen" challenge, she doesn't expect anyone to spend a million yen on a bowl of ramen. When the Hanazonos buy a bowl each, she's forced to run off and buy a ring from Tiffany's and a certificate of authenticity as toppings.
    • For the "Unfinishable Super-Sized Ramen" challenge, she puts everything in the kitchen into a single bowl, and the challenge isn't suggested to cost more than any normal sized bowl of ramen. Regardless of whether or not the customer beats the challenge, she's pretty much emptied her kitchen if not inventory of any food, and even if the customer fails the challenge she'll only be paid the amount of a single bowl, nowhere near enough to replace the food wasted. Fittingly, once Kurumi makes short work of the challenge, the owner closes up shop and files for bankruptcy.
  • Epic Fail: She has the improbable misfortune to have her next customer after coming up with a new ramen challenge be the one or two girls in Rentarou's Family who can take it on and win. By the second time around it's so bad her rigged lottery fails in the face of Momoha's abysmal luck.
  • Fire-Breathing Diner: Her initial challenge involves a super spicy ramen before making the challenge harder by making it boiling hot and steaming hot. Subsequent challenges drop off the spiciness and become weirder.
  • Impossible Task Instantly Accomplished: Her challenges may be crazy, but the Rentarou Family is so much crazier, forcing her to make up a new one every day:
    • Chapter 83's challenges:
      • "Damn Spicy Ramen": Kusuri and Yaku are unfazed, having had medicine that was spicier.
      • "Damn Boiling Ramen": Iku gets off on the pain of eating it.
      • "Damn Steamy Ramen": Mei's eyes and eyelids are unfazed.
      • "Damn Solid Steak Ramen": Momiji tenderizes the steak and makes it edible. After this is where it starts getting silly:
      • "Damn Sticky-Stainy-Curry Ramen" (finish it without making a mess): Mimimi eats so gracefully that she emerges spotless.
      • "Damn Dummy-DumDum Idiot Ramen" (designed to be too disgusting to order*): Miss Naddy is enamored with the "freedom" of the ingredients, and Chiyo ensures that she finishes it.
      • "Jugemu Jugemu Et Al. Ramen" (its full name designed to be impossible to enunciateThat being...): Nano remembers every single word.
      • "Rich Idiot Ramen" (priced at 1,000,000 yen*): Hahari and Hakari are more than capable of buying one bowl each.
      • "Unfinishable Super-Sized Ramen" (all the food in the kitchen packed into a ten-foot ball atop the bowl): Kurumi finishes every bite and asks for dessert.
    • Chapter 220's challenges:
      • "Crowded-As-Hell Ramen" (overflowing with deep-fried mini-crabs): Usa-chan loves the overcrowding.
      • "Crime-Scene-From-Hell Ramen" (designed to be too macabre to order*): Rin gets off on eating it.
      • "Blackpilled-As-Hell Ramen" (designed to be too despair-inducing to eat*): Meru is unfazed.
      • "Eco-Friendly-As-Hell Ramen" (no utensils allowed*): Tama laps it up easily.
      • "Cryptic-As-Hell Ramen" (the challenger isn't allowed to eat the ramen, and is in fact supposed to dump the bowl out): Uto rationalizes as she takes out some noodles that she's not eating the ramen, just the noodles, while Mai wins the challenge the intended way by accident.
      • "Sleepy-As-Hell Ramen" (overflowing with sleep-inducing incense): Nemu falls asleep and sleep-eats her ramen, even helping Saki complete her challenge as well.
      • "Eclectic-As-Hell Ramen" (the challenge is to identify the ingredients): Hasuha completes this one as soon as she walks through the door.
      • "Stringent-As-Hell Ramen" (has 100 suggestions to enjoy it to its fullest): Kimari is excited to disregard the suggestions and eat it the normal way.
      • "Infinite-As-Hell Ramen" (every time you finish a bowl, draw a lottery ticket, and if you win, you get another bowl free, but must finish it; the odds of losing are astronomically low): Momoha draws a losing ticket.
  • Mega Meal Challenge: Having failed one and been mocked for it in the past, she comes up with nine of these in both chapters she appears; the first is a simple "Damn Spicy Ramen" that fails to faze Kusuri and Yaku, and they get all the more outrageous from there.
  • The Perfectionist: When she says she wants her challenge dish to be unbeatable, she means unbeatable, abandoning each one as a lost cause as soon as a single person conquers it.
  • Revenge Before Reason: She set up her shop in the first place to take revenge at society after failing a ramen challenge. As such, she is more interested in creating an unbeatable challenge than in making any profit. At the end of Chapter 220, she outright says she's willing to go bankrupt with the Infinite Ramen if that's what it takes to "win".
  • Sanity Slippage: With every challenge that the Rentarou family overcomes, the challenges get wackier as she tries more and more ludicrous methods to make an unbeatable challenge. By the end of Chapter 220, her face is stuck in a Slasher Smile.
  • Screw This, I'm Outta Here!: At the end of both chapters where she appears, she throws down her headband in rage and shuts down her store.
  • Tempting Fate: For every new gimmick she creates, she is confident nobody on Earth would take the challenge, let alone complete it, because of its difficulty or wackiness. Right on cue, one of Rentarou's girlfriends with the right quirk proves her wrong.
  • Villain Ball: Though calling her a villain is a bit of a stretch, the "Infinite-As-Hell Ramen" is designed to ensure the only way to win is to pull out a losing ticket. Had she put only winning tickets in the box, the challenge would be impossible to beat.
  • You Were Trying Too Hard: If she didn’t keep changing the challenge dish every time someone beat it, nobody who tried it after would be able to beat it.

    God of Infinity (Unmarked Spoilers
https://static.tvtropes.org/pmwiki/pub/images/god_of_infinity.png

A deity providing over the Mugen Shrine. He grants Matsuri's wish for the festival to go on forever but has ulterior motives behind doing so.


  • Hellish Pupils: Representing his malevolent nature.
  • Holy Halo: A lesson that in this setting, being divine is not the same as being good.
  • Jackass Genie: He grants Matsuri's wish for an "Infinite Festival", but does so by overriding the personalities of the others so they'd care about nothing but festivals, Matsuri is horrified at the sight of them losing what made them unique. When she tries begging him to reverse it, he merely taunts her by stating it wouldn't be an infinite festival then.
  • Jerkass Gods: He wants to spread "Infinity" to everything, and is content with overwriting a person's personality to do so, as well as take advantage of those who pray at his shrine.
  • Oh, Crap!: Seeing the nightmarish visage of Rentarou resisting ten times a god's natural power scares the crap out of him, only made worse when Rentarou declares his intent to burn his shrine as punishment for making Matsuri cry.
  • Scary Teeth: Sharp teeth with prominent canines.
  • Unusual Ears: Has very long earlobes.
  • Walking Shirtless Scene: He doesn't wear anything on the upper half of his body, even at night, keeping his robe bunched around his waist.
  • Walking Spoiler: Not only is he the second major God to join the story after the God of Love, he's the first antagonistic God, setting the precedent that not only can other Gods be future antagonists, but that they could be Gods of concepts like "Infinite". His debut also coincides with Matsuri being the first girlfriend to interact with a God directly, let alone anything supernatural (aside from the fourth-wall breaks).
  • Winged Humanoid: A set of feathered wings.

    God of Love 

Voiced by: Shigeru Chiba (Japanese), Kenny James (English)

https://static.tvtropes.org/pmwiki/pub/images/lovegod_anime.png

A deity whom Rentarou meets while at a shrine. He's the one who gives Rentarou the chance to meet 100 soulmates, but due to a clerical error, should Rentarou choose just one before the goal is achieved, the other 99 soulmates will die of misfortune.


  • Butt-Monkey: His subsequent appearances have Rentarou constantly berating and threatening him for basically forcing 100 innocent girls to date Rentarou under threat of death.
  • Commuting on a Bus: He makes brief appearances once in a great while throughout the manga.
  • Dude, Where's My Respect?: Constantly complains that he is not being given the due respect owed a god. He sometimes shows up in Omake demanding more attention and merchandise.
  • Fanboy: He really seems to like Studio Ghibli films to the point of obsession, even watching Castle in the Sky while at work, which triggers a big mistake when he accidentally gives Rentarou 100 soulmates while subconsciously giving the film a score of 100.
  • God Is Flawed: Is easily distracted from his duties by watching anime, which is what caused Rentarou to get 100 girlfriends in the first place.
  • Good Is Old-Fashioned:
    • According to him, kids these days have no respect for their elders. No matter what Rentarou does, he will inadvertently disrespect him.
    • He also appears to be obsessed with old Studio Ghibli films, referencing them frequently. He can be seen eating fried egg on toast in the Season 1 title sequence, and subsequently in Chapter 164 of the manga.
  • Holy Halo: Has the typical golden halo above his head.
  • Loser Deity: As if all the other tropes here don't give enough of a hint. It says something when Rentarou considers him the only being he actually despises.
  • Non-Standard Character Design: He's recognizably in the same art style as everybody else, but he's drawn with far more detail (and in the anime, more shading).
  • No-Respect Guy: Constantly complains that the younger generation disrespects him. Even in the in-series popularity poll, he only gets one vote — and while he's not alone in that, the one vote is from himself.
  • Sitcom Arch-Nemesis: He's the only character that Rentarou remotely despises with a passion.
  • Small Role, Big Impact: After the first chapter, he's mostly relegated to brief cameos in the extras - even so, it's because of him that Rentarou has 100 girlfriends to begin with. Chapter 85 finally revisits him as a character, partly so Rentarou can bag on him, but also to reaffirm that he is sorry for essentially forcing 100 different girls to date Rentarou on pain of death (the main reason Rentarou hasn't told any of them about him).
  • Unusual Ears: He has long earlobes, commonly seen as auspicious in Asia.
  • Unwitting Instigator of Doom: Played With. His careless mistake endangers the lives of 100 girls, and Rentarou will never forgive him for it, but taking everything into account, the lives of said girls consistently appear to improve substantially after meeting Rentarou. Of particular note, Hahari accidentally saved the world once with her hair after taking one of Kusuri's drugs, which wouldn't have happened had Rentarou not shaved his head as part of his ploy to trigger a draw between Mimimi and Nano's beauty contest to keep them both in the family (which wouldn't have happened had he not been assigned more than one soulmate).
  • Winged Humanoid: He has feathered wings.

    Gorira Alliance/Gorilla Syndicate 

Leader voiced by: Kimiko Saito (Japanese)

Underlings voiced by: Risa Tsumugi, Hibiki Kuroki (Japanese)

Yuu voiced by: Yuki Sakakihara (Japanese), Katie Wetch (English)

https://static.tvtropes.org/pmwiki/pub/images/the_gorira_alliance.png

A motorcycle gang consisting of numerous Gonk-y thugs (their leader included) and one effeminate-looking boy.


  • Animal Motifs: They have the appearance and mannerisms of a gorilla.
  • Defeat Means Friendship: After their initial appearance, they're always friendly with Rentarou and company, even in situations where they're competing.
  • Everyone Has Standards: Chapter 166 implies the leader may object to Rentarou having so many girlfriends.
  • Girls Love Stuffed Animals: The leader Squees at a plush toy Yuu won for her.
  • Gonk: All of them are drawn to look like Gorillas.
  • Gonky Femme: A whole gang of them, though it's the leader who primarily falls into this.
  • Hot Guy, Ugly Wife: The leader of the Alliance is as Gonky as the rest of her underlings, yet she is dating the attractive effeminate Yuu.
  • Japanese Delinquents: They’re rough and ride motorcycles, making them a textbook example.
  • Lady Looks Like a Dude: The members (save the leader) all appear to be male, but the Eating Contest announcer says they're all women, save for Yuu.
  • Love at First Sight: The Alliance's leader and Yuu are soulmates in the same way that Rentarou and his girlfriends are. They met after she saved Yuu from being hit by a truck (by stopping it with her bare hands).
  • No Name Given: Yuu is the only member of the group with an actual name.
  • Opposing Sports Team: They appear whenever Rentarou and his family need a large group of antagonists to compete against.
  • Pitbull Dates Puppy: The gang's leader and Yuu, obviously.
  • Punch-Clock Villain: The group is willing to help Rentarou and his family get themselves out of a photo booth despite bashing heads with them multiple times.
  • Rescue Romance: Yuu met his girlfriend (and both discovered that they were soulmates) when she saved him from being run over.
  • Sarashi: Their leader wears one. The rest (except Yuu) wear white shirts under their coats.
  • Tiny Guy, Huge Girl: The leader is much bigger than Yuu.
  • True Companions: Like the Rentarou Family, the gang is always willing to give their all for their leader and she in turn will do the same for them and her boyfriend. During the food eating contest, despite all of them being full, they're so determined to win that they continue eating until they have to be escorted out in an ambulance.
  • Verbal Tic: The leader of the Alliance ends her sentences with "uho", Japanese onomatopoeia for a gorilla's hoot.
  • Worthy Opponent: They view Karane, and only Karane, this way. When sword fighting Kishika, the leader says if she isn't Karane, she's trash.

    Jurassic High Baseball Team 
https://static.tvtropes.org/pmwiki/pub/images/jurrasichigh_team_100gfs.png

Rapuko Beroki voiced by: Mari Kawase (Japanese), Marisa Duran (English)

Sauruko Terano voiced by: Farahnaz Nikray (Japanese)

The dinosaur-themed baseball team that Rentarou's Family faces off against to save Iku's baseball club.


  • Animal Motif: Dinosaurs. Everyone seen on the team has a reptilian look and name to match.
  • Break Them by Talking: Rapuko picks out Shizuka as the opposing team's weak link and destroys her self-esteem to make her slip up and serve them the win. She quickly realizes this was a mistake.
  • Crippling Overspecialization: Terano's "Tyranno Cannon" pitch is so powerful that just connecting with the ball will hurt the batter, but it's the only pitch she can throw and at the same angle every time. Even the weaker members of the opposing team can get by just by bunting it and it's very easy to guess where it will go. Shizuka, who is the second smallest person on the team, successfully bunts it with the handle of the bat because the pitch is that predictable.
  • Cuteness Proximity: Shizuka's running the bases reminds one of them of her Precious Puppy who passed away a year before and breaks her focus, leading her to tearfully congratulate a confused Shizuka when she's declared safe.
  • Defeat Means Friendship: Subsequent appearances show the team to be very supportive of the Rentarou family and look for any way to atone for their introduction.
  • Dick Dastardly Stops to Cheat: The team almost certainly would've won the practice game if Rapko hadn't insisted on teasing Shizuka to throw her off her game.
  • Jerkass: Rapuko. She goes out of her way to cripple Iku by slamming her Trauma Button and having Terano injure her arms with a pitch. And that's before she viciously tells Shizuka she's worthless just to score a win, causing the poor girl to have a breakdown on the field.
  • Jerk with a Heart of Gold: That said, the volume 5 extras show both teams going out for food together after the game and getting along, with Rapuko looking sheepishly apologetic to Shizuka for her unsportsmanlike behavior.
  • Nice Job Fixing It, Villain!: They were winning until Rapuko caused Shizuka to have a breakdown by making her believe she was worthless for the team, this made the rest of the family motivated to defeat them.
  • Opposing Sports Team: Serve as the antagonists for Iku's introductory arc.
  • Reasonable Authority Figure: The team's coach, a short, elderly woman, is much more laid-back and lets Rentarou sub in non-students when the other team is short on players.
  • Scary Teeth: All of them have either pointy fangs or full mouths of sharp teeth, going with their dinosaur motif.
  • Token Mini-Moe: The unnamed Ankylosaurus-themed girl is about half as tall as everyone else, and looks childishly cute. In a bonus scene with the Jurassic High team having yakiniku with the Rentarou Family, she's paired together with Kusuri, a Token Mini-Moe in her own team.
  • Villainous BSoD: Terano suffers one after her signature fastball is outsmarted. She's still sulking about it 27 chapters later.

    Jye'yan 
A classmate of Karato Inda and Honoka.
  • The Bully: Chapter 230 opens with Karane seeing him harassing her younger brother, Karato.
  • Inferred Survival: While he's last seen as a twitching mess from the impact of Karato's punch flinging him into a pole, the narration notes that "from that point on, [he] would never cross Karato again", implying he at least survived it.
  • It's All About Me: While taunting Karato, he calls himself "The Great Jye'yan".
  • Laser-Guided Karma: After spending most of the chapter using his strength to push Karato around, he gets a taste of the Inda family's "Tsundere factor" when Karane indiscreetly asks Karato if he likes Honoka, causing Karato to punch Jye'yan into a pole. He spends the rest of the chapter a twitching mess.
  • Shout-Out: His name is likely a reference to the bully Gian from Doraemon. The stripe on his shirt also matches Gian's hairstyle.

    Kiraisugi-chou's Mayor 
https://static.tvtropes.org/pmwiki/pub/images/kiraisugi_chous_mayor.png

The mayor of Kiraisugi-chou, who is obsessed with winning the annual sports festival against Sukisugi-chou.


  • Arc Villain: Serves as the main antagonist of the sports festival arc.
  • Cheaters Never Prosper: At first, Kiraisugi-chou is able to cheat their way into first place, but once the girls figure out how to exploit their own quirks, his plan falls apart.
  • Dick Dastardly Stops to Cheat: Despite rendering all of Sukisugi-chou's female competitors (sans Rentarou's girlfriends) out of action by slipping them Serious Kids' Beer, he still insists on having them conduct the relay race with an oiled baton. This proves to be his undoing when the official accidentally oils everyone's batons.
  • Hate Sink: One of the few characters in the manga intended to serve this role.
  • Meaningful Name: The mayor himself isn't named, but "Kiraisugi-chou" essentially translates to "Ihatethis Town". The editor's note explaining this questions why anyone would ever want to live there.
  • Opposing Sports Team: The athletes he hires for the sports festival.
  • Screw the Rules, I Have Money!: He uses his town's taxpayer money to hire professional athletes to compete for his town, and later tries to cheat his way to victory when the girls figure out how to exploit their own quirks.
  • Smug Snake: Is prone to displaying overconfidence when he thinks the odds are in his favor.
  • Unknown Rival: Apparently his entire personality revolves around hating and trying to beat Sukisugi-chou. Nano is the only one in the cast who can identify him.
  • Villainous Breakdown: After Sukisugi-chou wins the relay race, and thus the entire competition, he collapses face-down on the ground in a pool of his own blood.

    Newbie Idol 
https://static.tvtropes.org/pmwiki/pub/images/newbie_idol_anime.webp

Voiced by: Yurie Igoma (Japanese), Amber May (English)

An aspiring pop idol looking to release her debut album.


    The Serious Group 
A company headed by a distant relative of Iku that sells goods and services of extreme quality.
  • Acme Products: All of their goods and services have "Serious" in their names.
  • Adaptation Name Change: The official English translation gives them the name "Hardcore Group".
  • Anti-Villain: For the most part, they’re just a really eccentric company. One that indirectly causes problems for the family with their services because they don’t know how to tone it down.
  • Hot-Blooded: Its employees seem to be prone to yelling at the top of their lungs. Even a monk. Unsurprisingly, the company is owned by a distant relative of the just-as-Hot-Blooded Iku.
  • Serious Business: It's in the name. Its owner is of the opinion that "half-measures mean death!", changed to "Always hardcore!" in the official English version.
  • Unwitting Instigator of Doom: It seems that they don't make a habit out of informing the general public exactly what they consider serious quality.

    Takeko Superdeluxe / Chanko Bakunishiki 

Voiced by: Katsuyuki Konishi (Japanese)

A champion in many eating contests and a competitor in the contest attended by the Rentarou Family.


  • Adaptation Name Change: From Takeko Superdeluxe in the manga to Chanko Bakunishiki in the anime.
  • Arc Villain: Of the Food Fight Festival arc.
  • Big Eater: They compete alone in a team-based tournament, and almost come out on top. They actually cheat by using a large tank.
  • Cheaters Never Prosper: Their giant body actually conceals a tank to dispose of the food instead of eating it. By the end of the contest, the tank is filled and they are forced to use their own stomach, and ultimately lose.
  • Everyone Has Standards: They refuse to participate in the round with extremely spicy tofu, calling it an insult to food. Subverted as they just can't handle the spice and can't avoid it even with cheating.
  • Evil Gloating: When Kurumi finally hits her limit, can't eat any more and starts to break down, they mock her for her overconfidence throwing herself into every round. Cue the rest of the Family backing her up in a Heroic Second Wind.
  • Gender Flip: Takeko is female, while Chanko is male.
  • Gonk: Both versions look extremely obese and have ugly faces. Although their large size is to conceal the tank used to store food and their face is a mask.
  • Meaningful Name: Takeko's hair resembles a bamboo shot ("takenoko").
  • No Celebrities Were Harmed: Takeko is based on a real person named Matsuko Deluxe, which is likely the reason for their design change.
  • Non-Standard Character Design: They look enormous and are drawn significantly different from other characters. Chanko in particular has a robot-like appearance and an artificial voice. Rentarou describes them as someone straight out of One Piece. This foreshadows them actually being a costume on top of a smaller person.
  • Synthetic Voice Actor: In-universe, Chanko is using text-to-speech, although there's still a real voice actor behind it.
  • Verbal Tic: Chanko often adds "chanko" to his sentences. Official subtitles turn most of those into food-based puns instead.
  • Vomit Indiscretion Shot: Ultimately, they can't handle the final bit of ramen and throw up on-screen (covered by Pixelation).

    Tina Quali 
https://static.tvtropes.org/pmwiki/pub/images/tina_quali.png

A former pop idol who attempts to train Rentarou's girlfriends as pop idols.


  • The Bus Came Back: She returns in Chapter 152 after not appearing since Chapter 63.
  • Catchphrase: "Quality!"
  • Get a Hold of Yourself, Man!: Gives Hahari a slap of this variety when she tries calling it quits. Mei almost slaps her face off for it.
  • Lonely at the Top: Seeing the girls putting their hearts into their comparatively sub-par performance reminds Tina that she originally wanted to reach idol stardom with her friend, inspiring a change of heart towards her methods.
  • Punny Name: Her name in the Japanese order is a pun on "quality".
  • Screw This, I'm Outta Here!: She abandons the girls when the better-quality girls refuse to abandon the lesser-quality girls.
  • Took a Level in Kindness: Tina is much more patient while training the newer girlfriends than she was before, as the performance by Rentarou's Family caused her to gain a new appreciation for friendship. Not only is camaraderie now the first thing she prioritizes in her lessons, she actively tries to avoid tearing them apart.

    Visitor from a Parallel World (Unmarked Spoilers
https://static.tvtropes.org/pmwiki/pub/images/nanoeiai_2_parallel.png

An alternate version of Nano Eiai from a parallel universe, 20 years in the future.


  • Alternate Self: She is the future alternate counterpart to the main timeline's version of Nano Eiai. The main difference is her shorter hair, darker eyes, and much more robotic demeanor.
  • Ambiguous Situation: Not much is given regarding the past of this version of Eiai, aside from the idea she considers human attachment "meaningless" and is twenty years ahead of the Nano of the main series. While it's easy to believe this stems from her not having fallen in love with Rentarou in her universe, it's unclear what, if any, relationship with her world's Rentarou she had. Did she simply never meet him? Are they not soulmates in her universe? Did something bad happen to and/or because of him and her discarding attachments was a means to Never Be Hurt Again? Or does her world not even have a "Rentarou Aijou" in it?
  • Arc Villain: Although she only appears in the beginning of her debut chapter, Parallel Future Eiai serves as the main antagonist of the Synchronization Arc, with her actions towards Nano being the main threat to her relationship with Rentarou and the other girlfriends.
  • Blue-and-Orange Morality: Due to never embracing her emotions like her main timeline self, this Eiai's sense of morality is derived solely from "efficiency", and what would be the correct way to improve on it. To this end, she sees no issue in overwriting the timelines of parallel Nanos so that they'll be more in sync with her own since doing so means their timelines become more "efficient" despite how callous such an act would be, and is confused by the emotional turmoil this causes them since she sees it as doing them a favor by eliminating "meaningless human connections".
  • The Comically Serious: Despite her being an even more logical and rigid version of Eiai, she compliments her other self's understanding of the multiverse and use of the buzzword for the readers to understand it.
  • Control Freak: Tries to force her will onto the other parallel universe Nanos to make them be more like her.
  • Deconstructed Character Archetype: Like her main timeline self, she deconstructs the Emotionless Girl. In her case, she takes the archetype to its logical extreme and demonstrates just what a person who's truly abandoned emotion would be like. Her absolute lack of emotion means that her sense of morality operates purely on "efficiency" rather than conventional ethics, and she's unable to relate to other people entirely, not even her main timeline self. As a result, she's not really a person and more of a heartless machine that's willing to erase all of main timeline Eiai's relationships solely on the basis that it would be more "efficient", regardless of the main Eiai's actual wishes.
  • Dull Eyes of Unhappiness: In her introductory scene, in contrast to Nano's bright eyes, Parallel Future Eiai has dull, dark eyes, signifying how her pursuit of efficiency has gives her a lack of life.
  • Emotionless Girl: Taken to its logical extreme. This version of Eiai never formed human connections nor embraced her emotions like the Nano of the main timeline, instead devoting herself to pursuing efficiency and scientific progress. This has essentially left her a cold, unfeeling, robot, seeing any form of attachment or anything that gets in the way of efficiency as "meaningless", to the point of willing to irreparably alter the lives of other versions of herself to make their worlds more like her own in the name of efficiency, and expresses confusion over why Nano wouldn't want that.
  • Evil Cannot Comprehend Good: Less "evil", and more "emotionally dead", but she cannot understand why Nano doesn't want her to erase the bonds she has nor change her world, finding the notion illogical since she is "Nano Eiai" and should have the same priorities as herself.
    Eiai: What are you talking about? We are the same person. You should understand.
  • Future Badass: Nano Eiai was efficient, but in 20 years in a parallel timeline's future, this version of her manages to develop technology that can allow her to cross into other worlds. However, she aims to use her technology to synchronize as many worlds with different versions of Nano Eiai to be as efficient as possible.
  • Future Foil: Parallel Future Eiai is what Nano could have been had she continued her pursuit of efficiency and didn't love Rentarou. She acts the same way that Nano did back in the first chapter/episode they met, where she rejects socialization, calling it a waste. This is contrasted with Nano, who has grown past her isolated nature and has gained many friends spending time with the Rentarou family.
  • Lack of Empathy: Due to prioritizing efficiency above all else unlike the main timeline's Nano, Parallel Future Eiai considers anything her counterpart values to be a hindrance to her potential that she shows no compunction in erasing Nano's love life and friendships just so she can become as "efficient" as her. When Nano protests against this, Parallel Future Eiai struggles to understand her counterpart's feelings and why she wouldn't want her relationships to be erased, believing that Nano should agree with her since they are the same person.
  • Perpetual Frowner: Parallel Future Eiai shares the original Nano's trait of sporting a neutral frown. However, this serves to highlight her cold and detached nature, which contrasts the original Nano, who openly expresses emotions behind her frown.
  • Pure Is Not Good: As it turns out, living purely by the creed of "efficiency" has made her incredibly callous to other peoples' feelings and willing to ruin Nano's (and the other parallel universe Nanos') life in the name of making her "efficient" like her.
  • The Stoic: Deconstructed. Like the original Nano, Parallel Future Eiai expresses no emotions and never detracts from her composed demeanor. However, because of her lack of emotions, Parallel Future Eiai demonstrates a lack of moral compass as well by unhesitatingly attempting to synchronize the original Nano's timeline with her own with no regard for her counterpart's feelings and connections to others.
  • Straw Vulcan: Parallel Future Eiai is meant to highlight how Nano could have turned out had she not fallen in love with Rentarou and joined the Rentarou family, and ultimately how awful she'd become. She's cold, unfeeling, and behaves more like a robot than a person, and considers any form of emotional connection "meaningless" since they get in the way of efficiency, all while having no issue imposing her own will on other versions of herself since she is only doing what is most "efficient" in her eyes. This is in stark contrast to the main Nano who, while still clinical and socially awkward, has come to embrace emotional connections and truly cherish the Rentarou family, hence her distraught reaction at Parallel Future Eiai effectively trying to erase the bond they have with her without a second thought.
  • Vile Villain, Saccharine Show: In contrast to the show's comedic and parodic tone, this version of Eiai is portrayed in a dark and serious tone, putting her main timeline self through the absolute wringer by attempting to erase all the human connections that she's forged.
  • White Hair, Black Heart: She has silver hair like her main timeline's counterpart, but is also a cold, robotic woman who attempts to synchronize Nano's world with her own, thus erasing her from her friends' memories, solely to make Nano as "efficient" as her.

    Yukiko Nozawa 
https://static.tvtropes.org/pmwiki/pub/images/yukiko_nozawa.png

The manga's illustrator.


  • Creator Cameo: She's the artist of the series and has only made brief appearances.
  • Pixellation: Applied to protect her privacy, so whenever she shows up, she looks like a humanoid mass of pixels.
  • What If?: According to the Volume 9 extras, she would've been one of Rentarou's soulmates if the God of Love was drinking while filling out Rentarou's paperwork.
  • Workaholic: Rentarou worries that she's getting overworked, but at least some of it is down to her loving the characters, her "children". Even so, Rentarou and Momiji occasionally help her out, Rentarou with the art, and Momiji with massages.
  • You Will Be Spared: When a sleeping Rentarou has a nightmare of all his girlfriends dying, he threatens to kill the author, Rikito Nakamura, to rewrite the story. The folks at Shueisha would be atomized if they got in his way. Nozawa, however, would be spared because he needs her to do the art.
