No official height, weight, or blood type are provided in the source text.

Rentarou is an average-looking yet genuinely handsome black‑haired boy of medium height and build, recognizable by his thick, slightly bar‑code‑like eyebrows.

He is the central figure around whom 100 “fated” girlfriends gather, turning his supposedly normal school life into an escalating, chaotic mega‑harem.

Although his appearance is deliberately plain, it is repeatedly stated that he is “normally good‑looking” and far from unattractive.

Before high school he wore a traditional stand‑collar school uniform; in high school he wears his school’s standard blazer, whose color also inspired his official image color.

Rentarou is defined by extreme sincerity, empathy, and selflessness.

He is serious and polite, yet friendly and easygoing, which earns him popularity with both boys and girls.

He is not the usual “dense romantic comedy protagonist” who never notices anyone’s feelings.

On the contrary, he is highly attuned to people’s emotions and generally understands when someone likes him, though he can be surprisingly naive about relationships between girls, sometimes mistaking intense yuri‑like vibes for mere friendship.

He consistently respects others, addressing new girls by their family names until they become his girlfriends, at which point he starts calling them by their given names.

He avoids clever manipulation and prefers to face people head‑on, even when that makes his life far more complicated.

Rentarou is also extremely polite and earnest with adults, including teachers and authority figures.

Because he sincerely helps everyone around him, he is widely regarded as a model student and a genuinely good person.

Emotionally, he used to be fragile and unstable due to repeated romantic failures.

Meeting his “fated” girlfriends gradually heals that damage, turning his once‑gloomy mornings into times of near‑explosive happiness where he literally jumps out of bed thanking the sun, the Earth, and “everything in this world” for existing.

Rentarou is academically above average and athletically capable.

In the mid‑term exam he ranked 88th out of 240 students, and he is described as being good at both studying and sports.

He is physically tough but not invincible in a realistic sense.

His body is frequently battered by slapstick violence, dangerous hobbies of his girlfriends, and absurd training, yet his recovery speed is outstanding, to the point of seeming superhuman.

His everyday life is completely dominated by the needs of his numerous girlfriends.

He routinely overworks himself, running on little sleep, juggling dozens of dates, and throwing his body into danger to make them smile, yet he regards all of this as normal and gladly pays that price.

Rentarou has a surprisingly “normal teenage boy” side:

he gets excited about robots, missions, and dramatic plans, shouting things like “Mission start!” and even piloting a “Rentarou Robot” in the novel version with childlike glee.

He is terrible with horror.

Haunted houses and supernatural scares reduce him to a genuinely frightened mess, in stark contrast to his usual courage when his girlfriends are involved.

From birth until middle school graduation, Rentarou confessed to exactly 100 different girls.

Every single one rejected him.

His first rejection occurred at only eight months old in a facility called “Shota‑Loli Children’s Center”, when he confessed (in baby terms) to a girl nicknamed A‑tan and was turned down.

From then on, he devoted himself to self‑improvement and sincere, face‑to‑face confessions, always giving each girl his full, honest feelings.

Despite this, all 100 confessions ended in failure with eerily similar wording.

Girls consistently told him something like, “You’re a good person and a great friend, but for some reason I just can’t see you as a boyfriend; it’s impossible on a gut level.”

Because the real reason was metaphysical—he was cosmically reserved for “fated partners”—none of this was actually his fault.

However, Rentarou could not know that; he internalized the pattern as proof that he was somehow fundamentally unwanted.

This endless rejection produced intense self‑loathing and inferiority.

He came to feel that loving someone and wanting to be loved were curses, and that his very existence was being denied by the phrase “it can’t be you” over and over again.

The series later suggests that without his future girlfriends, Rentarou might have become the opposite of what he is now: not an “entity that knows only love”, but a “monster that never learned love at all”.

After experiencing his 100th rejection at his middle school graduation, Rentarou visited a shrine known as the “Matchmaking Like Crazy Shrine” to pray for a fresh start in high school.

There he met a Matchmaking God, who popped out of the offering box and explained the cosmic mistake behind Rentarou’s life.

God revealed that Rentarou had been the victim of a “soulmate setting error”.

Due to this divine misconfiguration, he had been assigned 100 soulmates instead of one, and they would all appear during his high school years.

Soulmates in this universe are defined as the best possible romantic partner for a given person.

They are so lucky that simply having a soulmate uses up an entire lifetime’s worth of good fortune.

However, there is a cruel catch: if a person meets their soulmate but does not end up in a mutual, loving relationship, they will soon experience severe misfortune and die.

Thus, for Rentarou’s 100 soulmates, not dating him equals death.

Additionally, God explains that, because of the error and its backlash, Rentarou is cursed in another way:

he cannot successfully date anyone who is not a soulmate, which explains his entire history of “friend‑zoned rejections.”

Soulmates also have distinctive mechanics.

When Rentarou and a soulmate make eye contact and visually recognize each other, they both feel a lightning‑like jolt, a “Bibiin!!” one‑sided instant love at first sight for the girl, and a gradually growing love for Rentarou over time.

However, this trigger can fail or be delayed if:

Rentarou’s vision is impaired (for example, by drugs or experiments).

The girl avoids eye contact due to fear, dislike, or shyness.

Circumstances prevent proper visual recognition.

Despite this grim framework, God does not force Rentarou to reveal the death condition to the girls.

Instead, Rentarou chooses not to use “you’ll die if you don’t date me” as leverage and tries to build genuinely happy relationships.

On the day of his high school entrance ceremony, Rentarou meets Hakari Hanazono and Karane Inda, two beautiful first‑year girls who both fall in love with him at first sight.

Their mutual attraction reflects the soulmate “shock” as soon as they lock eyes with him.

At their new school there is a rumor that if you present a pink four‑leaf clover while confessing, the other person will surely accept.

Hakari and Karane rush to the courtyard to search for one, hoping to confess to Rentarou with the blessing of this charm.

Four hours later, neither girl has found a clover.

Rentarou, however, spends that time quietly supporting them, bringing various drinks to keep them hydrated and showing concern for both of them.

Moved by his kindness, both girls confess to him almost simultaneously, even without the clover:

Hakari: “Rentarou Aijou, I… I like you. Please go out with me.”

Karane: “I… I like you too. Please go out with me.”

For the first time in his life, Rentarou receives confessions instead of giving them.

Overjoyed, he nevertheless faces an impossible dilemma: he cannot choose only one of them, because he loves them both too much.

To deal with this, he returns to the shrine to seek advice from God.

There he learns the vital detail that if he does not date a soulmate, she will soon suffer misfortune and die.

At first, Rentarou considers secretly two‑timing: dating both girls while hiding each from the other, as a way to “save them both.”

But his conscience and his experience as a serial rejectee stop him.

He remembers how much courage it takes to confess.

He decides that trampling on that sincerity with lies would be unforgivable, even “for the sake of saving their lives.”

He returns to Hakari and Karane, holding in each hand a pink four‑leaf clover he spent all night searching for.

Blushing furiously, he delivers his answer:

“Please… both of you, go out with me.”

He admits he simply cannot choose between them because he loves both too deeply.

Although initially shocked by his blatant “double‑dating declaration”, the romantic mood and his raw honesty overwhelm them.

Hakari and Karane, their noses bleeding from emotional overload, accept.

Rentarou vows, “I will absolutely make you both happy,” marking the beginning of his many‑girlfriend relationship and his mission to save all 100 soulmates.

Later chapter captions and promotional lines refer to him as “the boyfriend who will save 100 girlfriends.”

Rentarou’s core principle is that love should come from happiness, not fear.

He openly states that he does not want his girlfriends to date him simply because they are afraid of dying.

He says he wants them to have a love where they can say, “I’m going out with you because I’m happy,” not “because I don’t want to die.”

To him, forcing a relationship under threat of death is equivalent to being killed and having one’s happiness stolen by fate.

As a result, Rentarou:

Never tells his girlfriends that they will die if they do not date him.

Never uses the soulmate death condition as emotional blackmail.

Treats the divine rule as his own private burden, not theirs.

He is so devoted to their happiness that he consistently puts everything else below it, including his own life.

He has sworn that if he ever fails to love them all equally, he will “commit seppuku” and die, though this is meant as an extreme expression of determination rather than a literal plan.

He also has extremely strict personal ethics regarding sexuality.

He refuses to fondle his girlfriends’ chests just for fun, and when one girlfriend suggests a “chest‑pressing guessing game”, he declares he would rather resign from being the protagonist than do something so “dishonest.”

When he must touch them for unavoidable reasons, he sometimes wears metal gauntlets or uses Kusuri Yakuzen’s drugs to numb his sense of touch.

He wants romantic intimacy, but only in a way that respects every girlfriend equally and waits for appropriate maturity, likely adulthood or marriage.

Despite this, Rentarou is not asexual.

He clearly has sexual desire and reacts in a very teenage‑boy way to excessive fanservice: he gets nosebleeds when he accidentally touches a breast or sees too much skin, and once is blown so hard into a wall by shock that he leaves a crater.

To keep himself under control, he has worn a chastity belt modeled after Astro Boy’s underwear.

Some characters jokingly call him a “steel‑willed purity mage” for his almost supernatural self‑control.

Whenever his girlfriends are involved, Rentarou displays frankly inhuman abilities.

These include:

Traveling around Japan on foot to find good date locations (bikes puncture, trains cost too much).

Swimming across the sea like a giant sea turtle to carry a girlfriend who is afraid of bridges.

Fighting off dangerous wild animals to protect them.

Sucking up all droplets of a spilled liquid midair so that none hit the ground.

His senses, especially when love is involved, also border on supernatural.

He can recognize which girlfriend is printed on a can badge just by the way his heart reacts when he touches it.

He can distinguish subtle differences in the taste of plain white rice depending on which girlfriend served it to him.

Physically, he has ridiculous stamina and recovery.

He can be beaten to the point of full‑body fractures or used as a test subject for experimental drugs and still bounce back in improbably short time.

However, he is not literally invincible.

One arc shows him bedridden with a fever for a week after long‑term overwork combined with accidentally ingesting Kusuri Yakuzen’s “do this or you die” drugs three times in a row, each with a different lethal condition.

The anime opening showcases his over‑the‑top speed and multitasking.

On his way back to retrieve a forgotten item, he:

Restores Kusuri Yakuzen from a charred state to perfect grooming in an instant.

Runs alongside a moving bus while carrying Nano Eiai bridal‑style.

Swallows a massive array of items, from food and medicine to unopened canned tea and bento boxes, all shoved into his mouth by a girlfriend.

Over time, as his number of girlfriends increases, his “superhuman” side intensifies.

In early chapters, kisses leave him flustered and a single punch from Karane Inda can thoroughly wreck him; later he calmly handles consecutive kisses and shrugs off violent blows much faster.

Rentarou is both the emotional center and punching bag of the “Rentarou family,” the nickname for his huge collection of girlfriends and quasi‑family members.

He protects them, encourages them, and tries to ensure that they all get along.

He loves each girlfriend equally, genuinely believing each one is “the cutest girl in the world.”

He insists on giving every one of them individual attention, going on dates, listening to their worries, supporting their hobbies, and celebrating their quirks without favoritism.

If a new girlfriend joins, he always introduces her to the existing ones, sweating nervously each time.

He never treats the harem concept as a license to relax; he constantly worries whether he is being fair and whether everyone feels equally loved.

He also wants his girlfriends to be friends with one another.

He never forces them, but he does everything in his power to create an environment in which they can support and bond with each other, often orchestrating group activities or joint events.

Within the group, some girlfriends act as straight men (tsukkomi), calling out absurd behavior.

Rentarou himself often plays this role when meeting a new, extremely eccentric girlfriend for the first time.

However, when his own love switches into high gear, Rentarou becomes the biggest source of absurdity.

He’ll deliver impossibly long speeches of affection, perform insane stunts, or execute elaborate romantic gestures, leaving everyone else stunned while the narrator itself occasionally steps in as the “tsukkomi.”

Though the family is remarkably harmonious, their sheer number and extreme personalities mean their lives are dangerously chaotic.

Rentarou constantly suffers injuries, near‑death experiences, and heavy physical strain just to keep up with them.

At one point, when a girlfriend named Momiji (in the source text called “Momiji Shigemi”, a masseuse) massages him, she finds his muscles hardened like those of a forced‑labor prisoner, comparing his back to that of a robot or someone worked to the bone in a secret underground facility.

Even when he only had eight girlfriends (as in the novel), he pulled an all‑nighter to be their “24‑hour boyfriend” and go on dates with all of them in a single day.

He finances dates with a savings account he has nurtured since childhood.

He explains that he started saving very early because “If I ever meet someone who loves me, I want to be able to make her happy no matter what,” demonstrating how deeply his longing for love shaped his entire life.

When he acts drunk—or enters a drunk‑like mood—he becomes a boastful lover, endlessly bragging about his girlfriends.

He is also extremely grateful for their existence, often moved to tears when he feels how much they have changed his life.

Normally Rentarou is gentle, patient, and forgiving.

But if someone insults, harms, or belittles his girlfriends, he becomes frightening.

He has declared, “An eye for an eye, terrorism for terrorism,” indicating that he believes in mirroring the severity of harm done to his loved ones.

In extreme situations he appears ready to resort to arson or even murder if that’s what it takes to defend them, though this is mostly expressed in darkly comedic exaggeration.

In one notable chapter, a two‑page spread depicts him whispering personalized declarations of love to each of his then‑nine (anime version: eleven) girlfriends.

The sheer density of affection is so overwhelming that readers are joked to “give up reading halfway,” both laughing and feeling a faint sense of dread at his intensity.

In another major scene, Rentarou resists the power of the “Infinite God,” terrifying a godlike being until it trembles and apologizes on its knees.

This reinforces his role not only as a romantic lead but as a quasi‑mythic “love warrior” whose determination surpasses divine authority.

Despite living in a hyper‑sexualized comedic world, Rentarou maintains strict rules about physical intimacy.

He has never gone all the way with any girlfriend as of the current story.

His romantic activities consist primarily of hugging, kissing, and other relatively mild forms of affection.

He likely plans to wait until he and his girlfriends are adults or married before engaging in anything more, aligning with his focus on equality and long‑term responsibility.

When pushed into erotic situations, he struggles.

He blushes, gets nosebleeds, and in one instance, when Hakari seriously seduces him, he is visibly aroused (“pitching a tent”), proving his self‑control is an active effort, not a lack of desire.

Because many of his girlfriends have aggressive or unusual forms of affection, he enforces boundaries even more strictly.

He scolds them when they try to peek at him in the bath, emphasizing respectful, consensual, and fair treatment.

This over‑cautiousness has earned him nicknames implying super‑human chastity and self‑discipline.

Nonetheless, the narrative frames this not as repression but as his attempt to balance a complex multi‑relationship situation ethically.

The series is notorious for how extremely eccentric Rentarou’s girlfriends are.

Even when only around 35 of the eventual 100 have appeared, each is vivid enough to carry her own full romance story in another series.

Examples include:

A scheming, hyper‑erotic big‑breasted rich girl always plotting lewd scenarios.

A tiny, fierce, surprisingly strong tsundere blonde who often acts as the main straight man and hits him hard.

A childlike, small “bookworm” who speaks in wildly chaotic literary metaphors.

A hyper‑efficient cool beauty whose obsession with efficiency pushes her into bizarre behaviors.

Kusuri Yakuzen, a genius but airheaded “mad scientist” loli who invents terrifyingly irresponsible drugs.

Hakari’s mother, a voluptuous ultra‑wealthy school director whose motherly affection is so overwhelming it becomes dangerous.

A food‑obsessed kouhai whose eating habits define her life and who also plays a sub‑straight‑man role.

An always‑smiling, closed‑eyes maid with dog‑like loyalty and near‑perfect skills.

A stoic baseball girl whose training ethos slides into masochism.

A narcissistic beauty who worships her own efforts and spends enormous energy on self‑improvement.

A stealthy, ninja‑like knitting girl with exceptional sneaking skills.

An overly responsible, somewhat neurotic bespectacled kouhai who is also his cousin.

An Americanized Japanese language teacher obsessed with “freedom” and acting like an over‑the‑top foreigner.

A huge, gentle gardening girl who speaks in dialect and has immense physical strength.

A tactile‑sense fetishist who loves groping people, especially in yuri contexts.

Her grandmother, a former field nurse who looks like a little girl but has the mind and experience of an 89‑year‑old war veteran.

A knight‑like upperclass girl who awakens to dangerous fetishes anytime Rentarou praises or scolds her.

A low‑tension, sleepy gyaru who worships cuteness itself.

A fantasy‑obsessed pseudo‑poet influenced by wandering traveler archetypes.

A clumsy, emotionally unstable maid who adores her senior maids like elder sisters.

An ethics teacher deeply enmeshed in drinking, gambling, and lust yet still committed to “service.”

A violinist who also adores violence and sports sharp teeth.

A moody, numbers‑loving bespectacled girl who ironically struggles with actual math.

A physically outmatched capoeira‑using tan university student who cannot handle non‑physical confrontations.

A burned‑out former office worker who decides to become a cat in this life, not the next.

A singer who admires avant‑garde pop stars and aims to become a “genius oddball.”

A goth‑loli, festival‑loving half‑Japanese girl who speaks like a traditional Edo townsman.

A lonely upperclass girl with a “reverse trypophobia” toward clusters of people, needing others constantly around her.

A despairing but mentally iron‑willed picture‑book author who longs for fairy‑tale worlds.

A weak but hot‑blooded Yankee girl who deliberately repeats a grade because she values seniority.

A sleepwalking shoe‑crafting kouhai whose dream persona is practically a second personality.

A self‑declared detective and intense smell fetishist with a puppy‑like energy.

A disciplinary teacher who gets a thrill from breaking rules.

A twin‑tail‑obsessed lolita kouhai who treats that hairstyle like religion.

A school nurse who will never forgive anyone who harms her students.

And that is still only a fraction of the full 100.

Rentarou’s ability to sincerely love all of them, with their wildly dangerous and bizarre traits, is treated as both comedic and terrifying.

Here are some examples of how Rentarou and several key characters address each other:

Meru Zetsubouda first calls him “Rentarou‑kun”, then later “Rentarou‑kun” in a more intimate tone.

He calls her “Meru‑san” and later “Meru‑chan.”

Saki Tomogara calls him “Rentarou‑kouhai.”

He calls her “Saki‑senpai.”

Rookie Idol‑chan calls him “Rentarou.”

He calls her “Rookie Idol‑chan” (or by her idol nickname).

Friend A calls him “Rentarou.”

He calls them “Friend.”

A‑tan, his first crush, used baby talk to refer to him; he simply calls her “A‑tan” in memory.

These naming patterns show his mixture of respect, affection, and the gradual deepening of intimacy over time.

Although Rentarou is praised as a “true man” and “love warrior,” his inner self‑image is surprisingly negative.

He constantly downplays his own value and strongly believes that he is being saved by his girlfriends, not the other way around.

In one conversation with God, he insists that he is not making them happy; rather, they are the ones making him happy.

He sees his life before meeting them as a dark, joyless tunnel, and their arrival as the light that made life worth living.

He is willing to do poison tasting, life‑threatening tests, and reckless heroics under the excuse “it’s for them,” because he honestly feels that his life is worth less than their happiness.

This is not framed as healthy self‑esteem; instead, it is an inverse reflection of how deeply he adores them.

The story frequently contrasts his current overflowing love with the “what if” scenario of a Rentarou who never found love.

That hypothetical version of him—twisted by rejection and loneliness—would have been a terrifying monster who never learned compassion.

Instead, the actual Rentarou becomes a “monster of love,” an unnatural being whose only defining trait is infinite, unconditional affection.

He cries with gratitude when his girlfriends reassure him, and when they tell him “That’s our line” after he thanks them for saving him, it highlights how mutual their salvation really is.

Rentarou’s parents have not yet appeared directly, but he describes them as ordinary teachers in a normal home.

However, considering his cousin Chiyo Iin’s father’s bizarre antics and the extreme personalities of nearly all other side characters, the series hints that his idea of “normal” might not match the readers’ standards.

The only notable anecdote about his father so far is an incident where his father brought home chocolate liquor balls as souvenirs.

Rentarou, thinking they were regular chocolates, ate them and accidentally ingested alcohol, showing both his father’s poor risk assessment and Rentarou’s own lack of caution at the time.

His extended social circle includes teachers, classmates, part‑time workers, and even deities, almost all of whom are incredibly idiosyncratic.

Within that world, Rentarou ironically appears to be one of the more “normal” people, despite being arguably the biggest lunatic when it comes to love.

As the main character of “The 100 Girlfriends Who Really, Really, Really, Really, Really Love You,” Rentarou anchors a story that combines romantic comedy, harem antics, and absurdist gag humor.

He is often described within the story and by readers as the “polar opposite of Makoto Itou”, a notorious unfaithful protagonist from another series.

While typical harem protagonists are criticized for being oblivious, indecisive, or selfish, Rentarou is the opposite:

he is hyper‑aware, completely committed, and ready to sacrifice anything for his partners.

Because of this, comments about the series are unusual for a harem rom‑com.

Instead of saying “I envy the protagonist,” many readers say “I want to be the protagonist’s girlfriend,” echoing another Jump series’ meta‑line that “when you love the protagonist, you stop being a reader and become just another heroine.”

Rentarou’s reputation within the story is that of an “entity that knows only love.”

He is both admired and feared, even by gods, for the sheer magnitude of his devotion.

He is associated with a navy‑gray, slightly blue‑tinted color based on his school uniform.

Originally, his eyes were colored in shades of blue, but the creator later changed them to brown to better match the idea that he is just an ordinary boy despite everything.

In many ways, Rentarou Aijou is the ultimate subversion of the harem protagonist: a boy who truly, honestly, and exhaustingly loves every single one of his girlfriends and is prepared to shoulder the impossible burden of making all 100 of them happy.
