The 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.
- 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.
- Absurd Phobia: Implied. He throws himself awake three times in Chapter 56 when he dreams about getting intimate with one of his girlfriends, suggesting he has a Paralyzing Fear of Sexuality.
- 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 Men Are Perverts: Ultimately defied, or at least repressed. Rentarou finds his girlfriends extremely attractive, but he would never make a move on any one of them. Lampshaded when he started dating Mei and she said she would obey any command. A scan of his mind showed a small bit of desire surrounded by an overwhelming amount of pure love.
- 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 threatening a god into submission.
- 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.
- Character 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.
- 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.
- 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.
- 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 Pink Clovers, and his efforts only grow from there.
- 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.)
- 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 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.
- He does this of his own accord in Chapter 167 to play mommy with the newest round of babyfied girlfriends.
- Early Installment Character-Design Difference: Rentarou had blue eyes in early artwork, but this was changed to brown eyes in later ones.
- 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.
- Guile Hero: He's often quick to think up ways to please his girlfriends and/or help them escape from some kind of trouble.
- 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.
- 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.
- Inconsistent Spelling: The scanlation (and the fandom, as a result) uses "Rentarou Aijou", The Other Wiki uses "Rentarō Aijō", the official manga and anime translations use "Rentaro Aijo", and the anime website uses "Rentaro Aijyo".
- 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.
- 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.
- Meaningful Name: Both his first and last name contains a kanji meaning "love", and Aijou literally means "feelings of love".
- 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 scarring him to the point he passes out.
- Mysterious Past: In a 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.
- 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).
- O.O.C. Is Serious Business: The girls freak out when he starts groping them all of a sudden. Subverted as it was not actually him.
- Out-of-Character Moment: 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 says it was a joke almost immediately, but that was still very reckless, as he literally vomits Blood from the Mouth due to the act. Also, Iku is a major masochist who enjoyed the rejection (which is why he did it).
- 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.
- The Perfectionist: When it comes to being a boyfriend. His reaction to being rejected so often was to keep improving himself, and he's kept it up afterwards 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.
- 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 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.
- 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.
- 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.
- Sharp-Dressed Man: When Hahari dresses all the girls up as maids, Rentarou is dressed as a butler. The girls enjoy the look.
- 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.
- Trademark Favorite Food: Mei prepared an egg-based lunch for her date with Rentarou because Hahari told her he likes eggs.
- 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.
- That said, his acceptance does have its limits - 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 usually are only destined to have one.
- Violently Protective Boyfriend:
- 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".
- Though 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.
- It's gotten to the point that in Chapter 159, he mentions doing counterterrorism training.
- 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 opts 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.
- On his "date" with Mei at the park, she tells him that Hahari told her to obey any order he gives her. Once that sinks in, we are reminded that he is a teenage boy, as he freaks out, and the comic shows a diagram of his brain, which is 99% "love", but with "desire" right there in the middle. Fortunately, he snaps out of it once he realizes the implications, and just has her play fetch instead of anything bad.
- 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' families
Family members of Rentarou's girlfriends. Hakari's Father
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.
- 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".
- 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.
- The Nothing After Death: Ends up in a black void by Chapter 43, but doesn't seem to mind.
- Psychopomp:
- In Chapter 43, he is able to decide that it isn't Rentarou's time to die and sends him back to life (after Rentarou jumps from a helicopter to rescue Hahari from her world-engulfing hair).
- He also stopped everyone from losing their souls in the volume 9 extras.
- Soap Opera Disease: He was terminally ill with an unspecified disease when Hahari fell for him.
- 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
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.- Disappeared Dad: Possibly, since no mention is made of Karano's husband despite her having two children.
- 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.
- Theme Naming: All of them have given names staring with 'Kara,' even those who married into the family.
- 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. Rentaro 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
Voiced by: Madoka Yonezawa (Japanese)
Shizuka's mother.
- 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.
- Deconstructed Character Archetype: Is a Take That! at the Troubled Abuser who justifies themself by claiming it is for their victim’s own good and that ludicrously strict parenting is the solution to all problems in a child’s upbringing. Her unremitting harshness toward her daughter, even calling her creepy to her face, has only stifled Shizuka and made her speech impediment far worse than it would have been otherwise, and her defenses of her conduct are exceedingly hypocritical, all of them boiling down to “you are naive if you think the world will accept someone who can’t talk, therefore, I am justified in abusing her.” The only reason she isn’t completely irredeemable is that after Rentarou’s Armor-Piercing Question she realizes that she is wrong, that this is her fault and that she is a bad mother, and makes a token effort to appreciate Shizuka as she is, but although her daughter loves her unconditionally their relationship is still estranged.
- 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 appear to 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.
- 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.
- Self-Fulfilling Prophecy: As it turns out, her efforts at getting Shizuka to speak normally only made her more reluctant to do so.
- Shadow Archetype: She's an embodiment of who Hahari would've been if she wasn't one of Rentarou's soulmates.
- 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 two chapters, but she played a major part in Shizuka 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: 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
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.
- 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.
- 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
Kusuri's grandfather and Yaku's husband, a soldier Yaku 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 brim of his hat.
- Foil: To Rentarou, which Yaku lampshades. Her husband was a manly, taciturn soldier, while Rentarou is a considerate young man who never misses a chance to express his love in word or action, and finds acting like an old-fashioned forceful Manly Man too much for him.
- 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.
- 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.
- Abusive Parents: 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.
- The Ghost: Unlike other family members for girlfriends who get flashback chapters, they're not shown or heard from.
Ikuya Sutou
- 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 unrivalled masochist she is today.
Mr. and Mrs. Kakure
- 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
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.
- 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.
- 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.
- Foil: He's the opposite of Hahari. While Hahari freaks out when her daughter revealed she had a boyfriend and goes to incredible measures to break them up that are only foiled when she too gets zing'd, Hiro planned to have his daughter date Rentarou from the time she was born, and set up an elaborate scheme to make sure this didn't get derailed. Also, while Hahari initially does not approve of her daughter dating someone who has more than one girlfriend, Hiro is initially taken aback but quickly accepts it. Naturally, Hahari calls Hiro irresponsible once Chiyo joins the harem.
- 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.
- Incest Yay Shipping: He doesn't care at all that Chiyo and Rentarou are cousins.
- Long Game: His master plan involves 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.
- 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.
- 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 about 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.
- 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.
The Yamato Family
Naddy's, or rather Nadeshiko's, upper class family.
- Abusive Parents: Threw Nadeshiko in the warehouse because she couldn't play the koto.
- 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.
- Hate Sink: They're 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.
- 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.
- The Voice: Never seen, only heard from off-screen.
- 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
- 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
Grandma Meido
- Ascended Extra: She has brief non-speaking appearances in flashback during Mai's introduction in Chapters 101-102, then a speaking part and 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.
- Support Your Parents. Played with. When she lived with them, Momoha gave them significant financial support. Except they actually ended up disowning her 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.
Mr. and Mrs. Baio
- 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.
- Foil: Mr. Baio to Mrs. Yoshimoto. Both of them tried to suppress their daughter's unique quirks out of a worry the world would reject her for it. But where Mrs. Yoshimoto thought Shizuka was a freak for her nonverbal communication and told her so to her face, Mr. Baio loves Rin's sadism as much as the rest of her and she doesn't know about his attempts to dampen 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
- Good Parents: When little Suu starts bawling her head off at being parted from the numbers on the kindergarten's victory podium, her mother's 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.
Mr. Kaho
- Kick Chick: Gender inverted. He's a capoeirista, and brought Eira up to be one too.
- Parents as People: He 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: His 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
- 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.
The Dei Family
Matsuri's grandparents.
- Mobile Kiosk: They run a yakisoba stand which Matsuri helps out with.
- Shared Family Quirks: They talk in Shitamachi dialect (translated as Cockney in the scanlation) with lots of casual swearing; it's easy to see where Matsuri got it from.
Ohananomitsu High School
Vice-Principal
Voiced by: Kujira
The Vice-Principal of Ohananomitsu.
- Abhorrent Admirer: She tried to kiss Rentarou once for running in the hall.note
- 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".
- 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 occasional nickname, she's always referred to as the Vice-Principal.
- 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.
- Funny Afro: And it's large enough that Meme can hide inside it without arousing suspicion.
- Gonk: She's very ugly, and that's just wearing make-up. Her real face is implied to be even uglier.
- 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 "The Hag Closest to Supersonic Speeds in this World" / "Sonic the Sketchhag."
- 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's come out of it.
- Wall Crawl: She's shown crawling on walls in Chapter 150 of the manga and Episode 2 of the anime.
Fumi Utsushiro
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 like Hahari did.
- Stern Teacher: She believes Naddy's confusing mannerisms would cause trouble for students.
Toruru Kijineta
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 borderline 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 can snap a picture of Meme mid-Ninja Log.
- Character Catchphrase: "Hellohellohello!"
- 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. That said, she follows the club's rules about not taking photos of people without their knowledge and announces her arrival before each attempt.
- 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.
Others
Akogare and Manesu
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
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 sugggesting them to be a 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.
- 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).
- 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 Anonymous 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".
Asakawa
Voiced by: Satomi Amano
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.
- Brutal Honesty: Her bluntness in rejecting Rentarou makes him want to throw up instead.
- 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.
- 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.
- Character 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 are able to 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.
God of Infinity (Unmarked Spoilers)
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 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)
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 berate and threaten him for basically forcing 100 innocent girls to date Rentarou under threat of death.
- 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.
- 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 really says something when Rentarou considers him the only being he actually despises.
- 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.
- 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).
- 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.
- Winged Humanoid: He has feathered wings.

Jurassic High Baseball Team
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 that 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 hava a breakdown by making her believe she was worthless for the team, this make 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.
- Villainous BSoD: Terano suffers one after her signature fastball is outsmarted. She's still sulking about it 27 chapters later.

- 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.
- Opposing Sports Team: The athletes he hires for the sports festival.

- 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.

Newbie Idol
An aspiring pop idol looking to release her debut album.

- Exotic Eye Designs: Her pupils are X-shaped.
- Inferred Survival: She was last seen crashing in a helicopter during the tentacle hair incident in Chapter 43, but the news reports say that no one was injured, implying that she was confirmed to be okay.
- Ms. Fanservice: Her explanation of the Eating Contest she's MC'ing is accompanied by steamy gravure shots of herself. When called out on it, she claims the audience would prefer drawings from Nozawa more than a graph.

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.
- 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!"
- 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.

- The Bus Came Back: She returns in Chapter 152 after not appearing since Chapter 63.

- 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.
Yukiko Nozawa
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.
