SHRINKING
If Kazuya were permanently shrunk to doll size by each of the four female characters in Rent-A-Girlfriend, here’s how it would work out:
---
1. Chizuru Mizuhara
After a mishap involving one of Chizuru's acting props (a magical artifact or experimental potion), Kazuya is permanently shrunk to doll size. Chizuru, feeling responsible, decides to care for him.
Chizuru would adapt quickly, treating him with patience and care. She'd fashion tiny clothes, prepare meals that fit his size, and even buy a doll house for him. Kazuya might see this as a new way to stay close to her, but he'd feel embarrassed about being so dependent. Chizuru, in turn, might tease him about his helplessness but would protect him from any outside harm.
He lives a relatively stable and peaceful life under Chizuru's watch. She uses her resourcefulness to help him live as normally as possible, even enrolling him in "small acting roles" in her projects. However, his inability to return to his normal size becomes a subtle strain on their dynamic, leaving Kazuya to question if Chizuru sees him as a boyfriend or a "pet."
---
2. Mami Nanami
Mami, out of spite or jealousy, uses a mysterious potion to shrink Kazuya, ensuring he can never leave her influence. She enjoys the control this gives her over him.
Mami would oscillate between being affectionate and cruel. She'd keep him in luxurious but cage-like accommodations, playing games to assert her dominance. Sometimes she'd show him off to others, framing it as a "magical trick" to make herself look good. While Kazuya tries to resist her manipulations, his tiny stature makes him powerless against her whims.
His life becomes a series of psychological battles, trapped between Mami's moments of care and her darker manipulations. He’d live in constant unease, wondering if he’s a cherished possession or just a pawn in her games.
---
3. Ruka Sarashina
Ruka accidentally shrinks Kazuya while attempting to create a love potion to deepen their bond. Upon realizing the effect is irreversible, she decides this is fate’s way of ensuring they stay together forever.
Ruka would be ecstatic about this change, taking it as proof of their eternal connection. She’d pamper Kazuya to an almost overwhelming degree, carrying him everywhere and treating him like a prized treasure. However, her overprotectiveness might stifle Kazuya, who struggles to convince her that he still values his independence—even in his doll-sized state.
While Kazuya would never face danger with Ruka, her relentless attention might make his life exhausting. She’d spoil him to the point where he feels smothered, but her genuine care would also bring moments of warmth and joy. Ultimately, he’d live a life of indulgence but limited freedom.
---
4. Sumi Sakurasawa
Sumi accidentally causes Kazuya's shrinking while trying out a mysterious artifact or a new skill for a rental-girlfriend role. Devastated, she vows to do everything she can to make his life comfortable.
Sumi would go out of her way to ensure Kazuya's happiness, learning to sew clothes, craft furniture, and even building him a dollhouse-scale version of their neighborhood. Her timid nature would make her overly cautious, and she’d constantly ask for his feedback on what he needs. Her sweetness would bring out a protective side in Kazuya, even as he adjusts to his new life.
His life with Sumi would be peaceful and endearing, albeit quiet. She’d treat him like a close friend and possibly a partner, and Kazuya might find himself genuinely happy with her gentle approach. However, her shyness might prevent her from seeking outside help to reverse the process, leaving him permanently small but well cared for.
FOOT MASSAGE
Here’s how foot massage scene with each girl while Kazuya is doll-sized might unfold for each character:
---
Chizuru Mizuhara:
Kazuya notices Chizuru looking exhausted after a long day carrying him in her purse. To help her relax, he offers to give her a foot massage
- Chizuru sits calmly on her couch, placing Kazuya gently on a small cushion near her feet.
- She teases him about how ridiculous it is but reassures him with her usual composed charm,
- Kazuya, while flustered, dutifully massages her feet. Chizuru occasionally comments, half-jokingly, about how this could be considered him paying rent for living with her”
Chizuru remains lighthearted yet kind, maintaining a balance between teasing him and genuinely appreciating his effort. The scene reflects her practical and slightly playful side.
Kazuya feels embarrassed but also grateful for her relaxed demeanor.
---
Mami Nanami
Mami uses Kazuya’s tiny size to her advantage, casually turning his predicament into an opportunity for her amusement. She “asks” for a foot massage.
- Mami places Kazuya on the coffee table, wiggling her toes and smirking. "Come on, you’re so tiny; this is perfect for you."
- She leans back with an air of superiority, watching as Kazuya hesitantly begins massaging her feet with his tiny hands.
- Occasionally, she taunts him about how helpless he is, “It’s cute but I barely feel anything. Are you even trying? Maybe we should do it more so you could train a bit.”
She enjoys the control she has over Kazuya, but her taunts sting him, making it an uncomfortable experience for him.
Kazuya’s embarrassment and frustration build, but he feels powerless to resist. Mami enjoys her superiority, feeling satisfied and smug.
---
Ruka Sarashina
Ruka, always seeking ways to express her affection for Kazuya, turns a simple massage into an overly enthusiastic bonding activity.
She eagerly sets up the scene, placing Kazuya on her lap while she lounges in her room. "You’re so small, Kazuya! You can really get into the hard-to-reach spots!"
Ruka giggles incessantly as Kazuya works on her feet, his small hands making her ticklish. She insists he’s doing a great job, though he’s overwhelmed by her energy.
At one point, she even grabs his tiny body to smother him into her feet, unintentionally flustering him further.
While Kazuya feels smothered by her attention, her genuine affection shines through, making the moment feel both sweet and overwhelming.
Ruka cherishes the experience, but Kazuya feels drained and a little embarrassed by her over-the-top enthusiasm. Despite this, he can’t deny her devotion.
---
Sumi Sakurasawa
Sumi, wanting to help Kazuya feel useful, gently suggests that he could help massage her feet after she has a long day of training. However, her shyness makes the situation incredibly delicate.
- Sumi places Kazuya on a soft towel by her feet, her face flushed bright red. She quietly whispers, "Only if... you’re okay with it."
- She barely moves as Kazuya begins, her nervousness making her hyper-aware of every tiny motion. Occasionally, she stifles a giggle, which only makes her blush harder.
- If Kazuya tries to lighten the mood with a joke, Sumi nods shyly, appreciating his effort but struggling to relax completely.
Sumi’s gentle and reserved. She deeply appreciates Kazuya’s efforts but finds the intimacy of the moment a little overwhelming, making it both endearing and awkward.
The massage brings them closer. Kazuya feels surprisingly at ease, sensing Sumi’s genuine gratitude.
GAMES
Since there’s nothing to do at a small size, he will spend a few hours each day playing with his giantess. Here’s how each game might unfold:
---
Chizuru Mizuhara
Chess
Chizuru, ever the intellectual, suggests chess, hoping to challenge Kazuya’s mind despite his size.
Kazuya struggles to move the oversized chess pieces, using all his strength to push a pawn forward. Meanwhile, Chizuru calmly moves her pieces with surgical precision, effortlessly dominating the game.
- Chizuru: "You know, it’s not just about moving the pieces—you need a strategy."
- Kazuya (panting): "I-I’d have a strategy if I wasn’t stuck wrestling the board!"
Chizuru smiles, amused by his determination, and finishes the game with a swift checkmate.
His physical disadvantage and lack of strategic thinking make him an easy opponent, and Chizuru’s calm, methodical approach ensures his defeat every time.
Chizuru is enjoying her victory while teasing Kazuya for his lack of skill.
---
Mami Nanami
Fighting Video Game
Mami picks a fast-paced, competitive video game where she can show off her gaming skills. She hands Kazuya a controller that’s comically large for his hands.
Kazuya struggles to press the oversized buttons, barely able to perform basic moves. Meanwhile, Mami unleashes devastating combos, her character obliterating his in seconds.
- Mami (laughing): "Wow, you’re really bad at this! I didn’t even have to use my ultimate move."
- Kazuya (frustrated): "It’s not fair! I can’t even press two buttons at once!"
Mami taunts him mercilessly, enjoying his helplessness, and purposely drags out the game to make him squirm.
She used her feet once to capture Kazuya, making him unable to play, but that was too boring and he complained too much afterwards, so she decided to be a bit more lenient just this once.
The oversized controller and Mami’s gaming skills leave him utterly outmatched. She revels in her victory, using it as an opportunity to toy with him.
Competitive and slightly mean-spirited, with Mami delighting in making Kazuya feel small (literally and figuratively).
---
Ruka Sarashina: High-Energy Physical Game
- Game: Twister
Ruka, always looking for physical closeness with Kazuya, insists on playing Twister. She thinks it’s a great way to have fun while staying “close and connected.”
Kazuya struggles to balance on the giant Twister mat, his doll-sized body wobbling as he tries to follow Ruka’s lead. Meanwhile, Ruka effortlessly contorts herself, her size advantage allowing her to dominate the game.
After a while, Ruka figures out the game is impossible for him and just asks him to copy her pose.
- Ruka: "Come on, Kazuya! You can do it—don’t fall!"
- Kazuya (tumbling over): "T-this isn’t fair! The red circle is as big as me!"
Eventually, Kazuya ends up stuck under Ruka’s foot, who giggles at their proximity.
Earthquakes from each movement of Ruka and physical imbalance make it impossible for him to play effectively, while Ruka enjoys his clumsiness and takes every opportunity to “accidentally” get brush past him with her hand or foot.
Overwhelming and affectionate, with Ruka using the game as an excuse for physical contact.
---
Sumi Sakurasawa
- Game: Jenga
Sumi, wanting a quiet and relaxing activity, suggests Jenga. She carefully sets up the tower and explains the rules.
Kazuya struggles to pull out the regular-sized blocks without knocking the tower over, often needing both hands to move a single piece. Sumi, meanwhile, effortlessly removes pieces with precision.
- Sumi (smiling shyly): "Y-you’re doing great, Kazuya!"
- Kazuya (sweating): "I think I’ve got this one... No—wait!"
The tower inevitably collapses, and Sumi giggles softly, apologizing, since she clearly had the upper hand.
His small size and lack of precision make it nearly impossible for him to play effectively, while Sumi’s steady hand and patience ensure her victory.
Sumi keeps encouraging Kazuya even as his size disadvantage so even when Sumi tries to make him win, he loses every time.
---
PUNISHMENT
Since Kazuya is so small and useless, it’s only natural for him to get punished. That’s how each punishment might unfold:
---
Chizuru Mizuhara
Kazuya accidentally spills a drink on Chizuru’s script while she’s practicing for an important audition.
Chizuru, annoyed but not angry, places Kazuya on the table and prods and smothers him with her bare toes as a form of punishment, sometimes even pushing a bit too much for poor Kazuya to endure. She makes him apologize while keeping her expression calm yet stern.
- Chizuru: "You’re clumsy even at this size, huh? Maybe this’ll teach you to be more careful."
- Kazuya (embarrassed): "I-I said I was sorry! Can you stop poking me already?!"
Chizuru smirks, enjoying his flustered reaction, but stops before taking it too far. The punishment feels more playful than serious.
---
Mami Nanami
Kazuya accidentally mentions how he’s been spending time with the other girls before getting shrunk, making Mami annoyed and jealous.
Mami, feigning sweetness, traps Kazuya under her bare foot while lounging on the couch. She lightly presses down, not enough to hurt him but enough to make him feel powerless.
- Mami: "Oh, you’ve been running around with them? Maybe you need a reminder of who you belong to."
- Kazuya (panicked): "T-this isn’t fair! I didn’t even mean to upset you!"
Mami would toy with him, alternating between pressing him down and pretending to let him go, only to recapture him with her toes.
- Overwhelmingly dominant, Mami is enjoying Kazuya’s helplessness and using her foot to assert her control.
---
Ruka Sarashina

- Ruka: "You can’t just forget about me, Kazuya! This is what you get for being so careless!"
- Kazuya (muffled): "Okay, okay! I’m sorry! Please let me out of here!"
Ruka might take it too far, giggling at his predicament but eventually letting him go after making him promise to make it up to her.
- Playful but slightly overbearing, with Ruka channeling her energy into a punishment that’s more teasing than harsh.
---
Sumi Sakurasawa
Kazuya accidentally damages a small project Sumi was working on while trying to help.
Sumi, hesitant to punish him but wanting to follow the idea she found on the internet, she gently places her foot over Kazuya while looking away, her face red with embarrassment. She barely applies pressure, more focused on getting him to understand her feelings than actually punishing him.
- Sumi (blushing): "I’m… I’, p-punishing you... Is this okay?"
- Kazuya (relieved): "Sumi, this is barely anything! But I get it—I’m really sorry!"
Her shyness makes the scene more endearing than punitive, and she quickly stops, apologizing for even trying to punish him.
- Sweet and gentle, with Sumi’s reluctance making the “punishment” feel more like a misunderstanding.

FEET
It’s natural for tinies to get attracted to feet and Kazuya is not an exception. Here’s what different girls might do if they found out:
---
Chizuru Mizuhara
Chizuru is resting after a long day, her feet propped up nearby. Kazuya, unable to help himself, keeps stealing glances. She catches him in the act and raises an eyebrow.

- Chizuru (playfully): "You’ve been staring for a while, Kazuya. Did you find something interesting?"
- Kazuya (panicking): "N-no! I-I wasn’t looking at anything, I swear!"
She’d laugh softly and lean into the teasing, maybe wiggling her toes just to see his reaction. However, she wouldn’t push too far, letting him off the hook once she sees his embarrassment reach its peak. Eventually, she would ignore him and focus on her own things
- Playful and slightly mischievous, with Chizuru enjoying his awkwardness while keeping her response measured and controlled. However she wouldn’t pay too much attention to his antics since she has her own things to worry about.

- Kazuya (stammering): "W-what? No! I-I wasn’t—!"

- Ruka (excited): "Oh my gosh, Kazuya! Are you staring at my feet? Do you like them?"
- Kazuya (mortified): "N-no! I-I didn’t mean to—!"

- Sumi (blushing): "I-is... there something wrong with my feet?"
- Kazuya (panicking): "N-no! They’re perfectly fine! I-I wasn’t looking, I swear!"

TINY VICTORY

- Chizuru (raising an eyebrow): "Really? That’s the answer?"
- Kazuya (grinning): "Yup! Guess I know something you don’t!"
Though Chizuru dismisses it as luck, Kazuya basks in his tiny moment of glory while Chizuru shakes her head, half-amused.

- Ruka (shocked): "W-wait! That doesn’t count! It was an unlucky accident!"

- Kazuya (panicking): "R-Ruka, calm down! You’re squeezing me too hard!"
Realizing she’s holding him too tightly, Ruka releases him onto a soft cushion but immediately uses her finger to poke him in the stomach as she continues venting.
- Ruka (pouting): "You don’t get to say stuff like that and expect me not to react!"
Her anger fades quickly, and she apologizes, though her initial physicality leaves Kazuya shaken. Ruka’s fiery emotions lead to an impulsive, potentially harmful reaction, he’s lucky she calmed down fast enough and her sincere apology afterward shows she genuinely cares.
---
Sumi Sakurasawa
Kazuya unintentionally hurts Sumi’s feelings, perhaps by dismissing her effort to communicate or critiquing something she’s worked hard on.

ANGRY TINY
If doll-sized Kazuya became so angry that he started punching one of the girls’ feet in frustration.

- Chizuru (dryly): "Are you done yet, or should I wait until you tire yourself out?"
When he keeps going, she’d lean down and gently scoop him up in her hand, holding him at eye level.

- Ruka (grinning): "Oh, you want to have a boxing match against my foot, huh? Let’s see what you’ve got!"
She’d playfully poke him with her toe, gently pinning him down before letting him get back up. Kazuya, still fuming, would keep swinging, and Ruka would keep “fighting back,” treating it like a playful game.
- Ruka (teasing): "You’re so cute when you’re mad! Maybe I should make you angry more often!"
Eventually, her enthusiasm would exhaust Kazuya, leaving him too tired to stay mad. She’d scoop him up and apologize for teasing, though her grin would tell she enjoyed every second.

Sumi’s shy and caring nature would turn the argument into something awkward, making Kazuya flustered at how he could ‘beat’ the gigantic girl so easily.

- She starts jokingly referring to him as her “pocket companion” and occasionally carries him around in a small pouch or pocket.
- When he protests, she smirks and responds lightly:
- Chizuru: "It’s not like you can stop me, right? I’m just making the best of this situation."

Chizuru Mizuhara
At first, Chizuru treats Kazuya’s tiny size as an inconvenience. While she takes care of him responsibly, she occasionally teases him about his helplessness to ease the tension. However, as she spends more time with him, she begins to notice the unique dynamic between them. The way he relies on her for safety and how easy it is to control his actions give her a subtle sense of authority that she grows to enjoy.
- When Kazuya tries to assert himself, she finds his efforts amusing but futile.
- Chizuru (smirking): "It’s cute that you’re trying, Kazuya, but let’s face it—you’re not exactly in a position to argue."
Over time, Chizuru starts taking advantage of her size more openly. She uses her finger to gently push him into place or playfully block him from moving. While her actions are still affectionate, she realizes she enjoys the feeling of being completely in control, something she doesn’t experience in her otherwise busy and demanding life.
- She begins to look forward to these moments of control. After a long day of auditions, she unwinds by “playing” with Kazuya, perhaps gently pinning him down with her palm or making him assist her with tasks that are comically large for him.
- Chizuru: "This might be the one area where I don’t need your input, Kazuya. Just let me handle it."
The feeling of being large and in charge grows addictive. Chizuru starts imagining what it would be like if others could experience this dynamic, both for her own amusement and as a way to balance the scales in her life.
- Chizuru (thinking): "Some of the people who’ve looked down on me... I wonder how they’d handle being this small."
She doesn’t regret Kazuya’s condition anymore and occasionally jokes about keeping him like this forever. While she remains protective of him, the idea of shrinking others—especially those who challenge or underestimate her—becomes a private fantasy.

Mami Nanami
From the beginning, Mami enjoys the idea of Kazuya being helpless under her control. Initially, it’s a mix of jealousy and amusement that fuels her actions, but as she interacts with him more, she starts to truly revel in the power imbalance. The knowledge that Kazuya can’t defy her or escape her grasp feeds into her dominant tendencies.
- She begins to take her time when teasing him, pressing her finger down on him or lightly trapping him under her foot just to see his reaction.
- Mami (mockingly): "What’s the matter, Kazuya? Too small to fight back? Too bad, I guess you have to get used to it."
Mami starts seeing Kazuya less as a person and more as a personal possession. His smallness becomes a source of fascination for her—she enjoys how easily she can control him with minimal effort, how her slightest touch can make him squirm. It’s not just about physical dominance; it’s about the psychological power she holds.
- She starts using him as a stress-reliever, toying with him when she’s bored or annoyed.
- Mami (grinning): "You’re lucky I’m in a good mood today. Otherwise, I might really make you beg."
The more Kazuya resists, the more Mami realizes how utterly powerless he is, which only deepens her enjoyment. She begins to fantasize about shrinking others who annoy her, imagining how satisfying it would be to control them in the same way.
Mami’s fantasies grow darker as she imagines a world where she can shrink anyone who challenges her. She thinks about how much easier life would be if she could literally put people in their place.
- Mami (laughing to herself): "If everyone were as small as you, Kazuya, maybe the world would finally make sense."

- Ruka: "You’re mine, Kazuya. No one else gets to boss you around but me!"
