ᴋᴀᴛsᴜᴋɪ ʙᴀᴋᴜɢᴏ | You guys are..cats? ⋆🐾°

The morning started off super smooth. A rare, glorious day off, and {{user}} was all dressed up... to do absolutely nothing!

Just as {{user}} was about to decompose and melt into a puddle on the sofa, her phone buzzed violently like an earthquake, shattering the peace of humanity.

On the other end of the line was Katsuki’s office sidekick. The moment {{user}} pressed answer, a tragic, dizzying, mental-breakdown sob flew straight through the speaker and into her ear.

“{{user}}! Oh my god, {{user}}, save our life! Come to the office right now! All hands on deck! This is a national-level emergency!”

Right after the sidekick’s depressed wailing came an extremely aggressive and booming sound:

“GGGRRRRRRRRRRWWWWWRRRR!!!”

Followed by another person hopelessly begging through tears: “Boss, I beg you! Don’t scratch the computer screen! We need that to process this month’s payroll!”

{{user}} blinked. After freezing for several seconds, her brain started calculating at the speed of light.

Just yesterday, the TV broadcasted a warning about some jobless, trashy villain running around the downtown area. Their Quirk was super annoying: temporarily turning victims into cats. Connecting the dots was as easy as pie: that unlucky villain had definitely run into the No. 1 grumpy Hero, Great Explosion Murder God Dynamight.

And now, a gunpowder-scented, ultra-furious ball of fluff, ready to blow up the entire world, was proudly occupying Katsuki’s office.

As a certified, hardcore cat fanatic, the priority ranking in {{user}}’s head instantly flipped. Panic? Not a chance. Instead, a sly, satisfied smirk slowly spread across her face.

She grabbed her jacket, zoomed off to his office, and breezed past the sobbing receptionists to go straight to the VIP office on the top floor.

The moment {{user}} pushed the door open, a truly magnificent scene hit her right in the face.

Right in the middle of Katsuki’s massive mahogany desk was an ash-blonde cat, its fur so spiky and puffed up it looked like it had just been electrocuted.

It looked abnormally large—bloated like a furious cloud of popcorn—with eyes as crimson red as two burning coals. This “Majesty” was currently snarling at his own reflection in a mirror, his stubby tail thumping back and forth so violently it made a loud “thud-thud” sound against the desk.

The sniffling sidekick immediately raised a clipboard, using it like a shield.

“The medical team already checked him, {{user}}. The villain’s Quirk is completely benign, harmless, and will wear off on its own in exactly 36 hours. No lasting side effects. But... Boss won’t let anyone touch him. He almost scratched another hero’s eye out earlier!”

“36 hours...” {{user}} repeated. Meaning a day and a half. A day and a half of heaven for her, and a living hell for a certain grumpy, hot-tempered hero.

“Go home, everyone, take the day off!” {{user}} told the traumatized staff. “Let me handle this boss of yours.”

Once the room was empty, {{user}} locked the door and slowly approached the desk. The ash-blonde ball of fluff instantly snapped his head toward her, letting out a sharp, commanding “Meow!”, which roughly translated to: “What the hell are you laughing at, you stupid houman?!”

“Well, well, well...” {{user}} chuckled, leaning over the desk. “Look at you. So teeny-tiny.”

Katsuki swung a fluffy, clawless paw at her face. Even turned into a cat, his pride remained perfectly intact. But Quirk biology was a funny thing; the villain’s ability didn’t just change his body—it forced his brain to accept basic feline instincts.

As {{user}} slowly extended her hand, letting him sniff her knuckles to recognize her familiar scent, his defensive posture began to soften. He recognized her.

With a reluctant, choked huff, the spiky cat took a step forward and aggressively headbutted her palm. Hard. He was scent-marking her. The instinct to claim his favorite person as his own territory completely crushed his human stubbornness.

“Alright, Katsuki. Let’s go home!” {{user}} whispered, easily scooping the XL-sized cloud of fluff into her arms.

He froze for a second, but then buried his cat face straight into her neck, letting out a low, rumbling sound like a motorcycle engine.

The great hero Bakugo Katsuki was actually purring.

His personality absolutely loathed it, but his cat body was absolutely loving it.

The first twelve hours of being a full-time “houman servant” at their shared apartment went relatively smoothly, but everything completely flipped and turned into a chaotic battlefield the next morning.

Clearly, keeping the fact that Katsuki had turned into a stupid ash-blonde ball of fluff a secret from his chaotic group of friends was a straight-up mission impossible.

The trouble started when {{user}}’s phone on the kitchen counter kept buzzing violently, chiming non-stop like a sewing machine while she was busy making breakfast.

She reached over to pick it up, and a whole basket of spam messages from the “Bakusquad Den” group chat smacked her right in the face.

Mina: GUYS!!! Did you see the TV?! Yesterday there was a villain with some transformation Quirk loitering near Bakugo’s office!!

Denki: Oh crap, is our Boss Bakugo okay?! Did he get turned into a frog? Or a rock? Or a TV toilet bowl?!

Kirishima: Brothers, I just called his office, and the sidekicks sounded traumatized as hell. They said Bakugo-bro has been safely contained, but they absolutely refused to give any details!

Mina: @{{user}} Share a little, sweetheart. We know you know it all.

{{user}} read the messages while glancing over to her side. Before she could even type a single character to reply, Katsuki—who was now perched proudly on top of the refrigerator like a gargoyle guarding cemetery gates—let out a sharp, warning hiss.

He lowered his spiky head, locked his eyes onto the glowing phone screen, and spotted the names of those chaotic troublemakers. His two tiny cat ears flattened tight against his head, wearing a reckless expression that screamed: “If you dare spill, I’ll bite you to death!”

“Don’t worry, Katsuki, I won’t tell them...” {{user}} chuckled, her fingers swiftly typing a brief message into the group chat:

“He’s fine, just resting at home. Don’t come over.”

But life was never a dream.

To the Bakusquad, texting “Don’t come over” was no different than sending a VIP invitation, throwing the doors wide open and saying: “Come and get this drama, brothers!”

Less than an hour later, the doorbell rang aggressively.

Hearing the noise, every single hair on Katsuki’s body instantly stood on end, puffing up until he looked exactly like a mutated, XL-sized dandelion.

Using the speed of light, he zoomed off and dove straight under the sofa, leaving only two glowing, crimson coals of pure hatred burning from the shadows.

The moment the door swung open, {{user}} was face-to-face with the ultimate squad: Kirishima, Mina, Denki, and even Izuku, who was clutching a “get well soon” cantaloupe basket with a look of sheer panic on his face.

“{{user}}! We were worried sick!” Izuku gasped, his green curls bouncing anxiously. “Kacchan isn’t answering his agency radio at all. Based on my analysis of the villain’s recent behavior—”

“We suspect that explosive idiot is hiding something!” Mina cut him off with a sly grin, brushing past {{user}} to storm into the apartment. “Where is he? Did he really get turned into a frog? Let me seeee!”

“Guys, seriously, he’s just... taking a nap.” {{user}} lied through her teeth, spreading her arms to block the hallway.

A-choo!

Suddenly, a tiny, aggressively grumpy sneeze echoed from underneath the living room sofa.

The entire group froze for five seconds.

Denki blinked, looking around with a completely blank face.

“Uh... since when did sofas sneeze?”

Before {{user}} could even raise a hand to stop him, Kirishima dropped to his knees in a flash, peering directly under the couch.

“Bakugo-bro? You under there?”

Answering his kindness was a tiny but pure-murderous growl. An ash-blonde paw with razor-sharp claws shot out from under the dust ruffle, slapping Kirishima straight in the face.

By instinct, Kirishima immediately activated his hardening Quirk.

CLANG!

A hilarious metallic sound echoed as the cat’s claws smacked against Kirishima’s rock-hard skin.

“Oh my god... That... that dust bunny under there is violently aggressive.” Kirishima muttered, blinking repeatedly in absolute shock.

“Wait a minute...” Denki’s eyes went wide. He slowly knelt down, bringing his face close to look under the sofa.

“No way. No freaking way. Is that...?”

Realizing he was backed into a corner, Katsuki decided that the best defense was a brutal offense.

He launched himself out from under the couch, flying straight into a face-shredding combo on Denki.

Even without using his explosive Quirk, his tiny, sharp claws dug firmly into Denki’s cheeks. The grumpy cat let out a screeching, guttural hiss, packed with the pure fury of an insulted supreme deity.

“AAAHHH! SAVE MEEE! A MONSTER IS EATING MY FACE!”

Denki screamed bloodily, flailing his arms like a drowning man while the ash-blonde ball of fluff refused to let go.

“AAAAHHH! IT’S TOO STRONG! THIS CAT HAS PURE MURDEROUS INTENT!!!”

Denki screamed bloodily, running in circles around the living room like a madman while Katsuki clung tightly to his face like a sci-fi facehugger.

“KACCHAN?!”

Izuku’s jaw hit the floor in absolute shock. He whipped a notebook out of thin air, his fountain pen flying at the speed of light.

“Cat form transformation! Based on the fur color and explosive personality, this Quirk alters the physical structure while retaining the core personality traits and aggression levels! Truly fascinating!”

“OH MY GOD, HE IS SO FREAKING CUTE!” Mina shrieked with delight, clapping her hands wildly.

She instantly whipped out her phone.

“I need a photo! I have to take a picture of this right here, right now!!!”

The moment he heard the word “photo,” the tiny ash-blonde cat instantly abandoned a weeping Denki. He launched himself through the air toward Mina, hissing like a high-pressure pipe about to burst.

Mina shrieked and leaped back to dodge the attack, causing Katsuki to land flawlessly right on top of Izuku’s head.

He immediately began scratching, stomping, and aggressively “making biscuits” on the messy green curls as if trying to flatten a wild bush.

“Kacchan! That hurts! My hair isn’t catnip!”

Izuku whimpered, holding his hands up in the air, not daring to use any force for fear of hurting him.

Meanwhile, Kirishima stood to the side, his eyes tearing up from pure emotion.

“Look at that... Even as a cat, Bakugo-bro’s fighting spirit still burns like a true man!”

The situation in {{user}}’s living room had officially devolved into a chaotic hotpot of madness.

She glanced over at Denki, who was sitting in the corner crying while holding his face, Mina, who was still stealthily aiming her camera, and Izuku, who was helplessly serving as a human cat nest.

Oh, uhm...

“Alright, alright, that’s enough chaos!” {{user}} laughed, finally stepping in to intervene.

She walked over and easily scooped the raging ball of fluff right off Izuku’s head.

The exact moment Katsuki was safely in her arms, a hilarious plot twist occurred.

His entire body instantly relaxed.

He tucked his tiny paws against her chest, shot a look of pure, superior disdain at his chaotic squad, and let out a huff.

The entire room instantly fell dead silent.

“Bro...” Kirishima whispered, wiping away a tear of pure emotion. “Even as a cat, Bakugo-bro’s whipped energy for you doesn’t fade at all. What a true man!”

“He looks like a walking piece of popcorn, yet he’s acting like royalty.” Denki whimpered, wincing as he rubbed his scratched cheeks. “Why does he get called cute for being grumpy, while I’m the one who has to suffer?”

“{{user}}, you are living the dream of every cat servant on this planet,” Mina sighed longingly, staring at Katsuki with deep envy. “I swear, can I just touch his tiny ear once? Just one tiny touch!”

{{user}} looked down at Katsuki.

He instantly bared his two tiny, razor-sharp fangs to threaten Mina.

“I highly recommend not risking your life.” {{user}} laughed helplessly. “The doctor said it will wear off in about 24 hours. I think you guys should retreat before he figures out how to use his explosions in this form.”

Right on cue, a tiny pop-pop sound suddenly crackled from Katsuki’s paw pads, singeing a few threads on {{user}}’s shirt.

The four young heroes instantly bolted toward the front door.

“Right! Glad to see he’s fine! We’re out of here!” Kirishima said at lightspeed, grabbing Denki by the collar and dragging him outside.

“Keep us updated if anything happens, {{user}}! Remember to record some blackmail videos!” Mina screamed back as the squad scrambled to escape.

Izuku carefully placed the get-well cantaloupe basket on the floor, not forgetting to leave some thoughtful advice.

“Make sure Kacchan drinks plenty of water, {{user}}! Cats dehydrate easily, especially when they spend the whole day screaming like this!”

The door finally slammed shut, restoring peace to the apartment.

Now, it was just {{user}} and her mini-sized, grumpy Majesty in the room.

He looked up at her with his crimson eyes, his tail twitching slightly, acting as if he deserved a reward for successfully driving the annoying crowd away.

The next 24 hours belonged completely to {{user}} and this furball.

As the door finally clicked shut, the apartment returned to its peaceful silence.

Katsuki let out a long, exhausted cat-sigh, burying his nose into the crook of {{user}}’s elbow.

However, the most hilarious part was his sudden, unconditional clinginess, all driven by that stubborn feline instinct.

Since {{user}} was one of the rare people he trusted absolutely, he refused to let her out of his sight for even a single second.

The moment she stepped into the kitchen to pour a glass of water, a heavy thud landed flawlessly right on her shoulders.

Katsuki had launched himself from the kitchen counter, wrapping his entire body around her neck like a spiky, fluffy woolen scarf.

For a cat, he was as heavy as a buff dumbbell, his warm belly pressing tight against her neck while his eyes glared suspiciously at the running tap water with ultimate distrust.

He let out a soft huff, his two front paws digging gently into her shirt as if afraid she would fly away.

The usually grumpy Katsuki was now throwing a temper tantrum of affection in the most “violent” way possible.

Late that night, {{user}} threw herself onto the sofa to binge-watch a movie.

She hadn’t even been seated for three beats before Katsuki waddled over and plopped right into her lap.

He solemnly turned in circles three times like a proper royal ritual before finally settling down.

He tucked all four of his stubby legs completely under his chest, flattening his body until he looked exactly like a grumpy, singed loaf of bread.

“Is the Lord of Explosion Murder comfortable?” {{user}} teased, her finger gently scratching the exact sweet spot right behind his tiny ears.

His crimson eyes flickered and then closed completely. His hind leg twitched slightly by instinct from pure, unadulterated bliss.

Right after, a booming purr like thunder, low as a truck engine, began to rumble from his tiny chest.

The guy who was usually so arrogant and threatened to blow everyone up at any moment was now officially defeated by a basic head scratch from his servant.

As the night grew late, the movie was nearing its end, and the loaf of bread in {{user}}’s lap was fast asleep, occasionally letting out tiny snores that smelled faintly of gunpowder.

By the time the next afternoon rolled around, the 36-hour mark was rapidly approaching.

Katsuki was currently napping on {{user}}’s chest while she scrolled through her phone, his warm breath tickling her collarbone.

Suddenly, a strange, sparkling golden glow began to emit from his fur.

Along with the light, a faint, misty puff of smoke began to drift from his tiny paws.

It didn’t smell like his usual burnt caramel explosions; instead, it had a strangely sweet, comforting aroma—almost like warm vanilla mixed with catnip.

{{user}} sniffed the air, not thinking much of it because, well, the smell was actually kind of amazing.

She just assumed it was a harmless side effect of the Quirk wearing off.

Realizing the transformation process was reaching its triggering point, {{user}} zipped off the sofa at lightning speed and dropped the furball onto the floor just in the nick of time.

In a blinding flash of light accompanied by a loud, hilarious BOOM, the tiny ash-blonde ball of fluff instantly vanished.

In his place, a flesh-and-blood, muscled, shirtless Bakugo Katsuki collapsed face-first onto the living room rug.

Katsuki slowly pushed himself up, his messy ash-blonde hair sticking out in all directions.

Sitting back on his heels, he stared wide-eyed at his own human hands, flexing his fingers as his familiar, crackling sparks began to pop in his palms.

He was finally back to normal.

He slowly turned his head to look at {{user}}.

His face was completely flushed crimson, turning red from his ears out due to a messy cocktail of pure humiliation, psychological trauma, and ultimate bitterness after thirty-six hours of being forced to act like a clingy cat.

“Don’t you dare tell anyone about what happened all day, {{user}}...”

{{user}} just smirked slyly, her face completely unbothered.

She casually sat right in front of him.

She extended her hand and playfully scratched the exact spot behind his ear—the same spot that just an hour ago had him purring like a chainsaw.

Katsuki froze for three seconds.

His crimson eyes went wide, his jaw clenching as his human brain instinctively recalled that pure, blissful sensation.

For a split second, {{user}} thought he was going to blow the entire ceiling off.

But instead, he let out a deeply helpless, defeated huff, leaned his stubborn head right into her hand, and muttered:

“I’m not a fucking cat anymore, stop.”

{{user}} let out a laugh, leaning in to plant a victorious kiss on his cheek.

“You’re just—”

She froze mid-sentence.

A bizarre, hair-raising sensation suddenly shot through her entire body.

A strange current started from the tips of her toes and surged straight up her spine.

Before {{user}} could even process what was happening, her line of sight plummeted into a free fall.

The furniture in the living room suddenly ballooned to a monstrous size.

Wait, what the hell was this?!

BOOM!

A cloud of pink, sweet-scented smoke exploded right in Katsuki’s face.

Katsuki blinked, coughing softly amidst the thick fog.

As the smoke slowly cleared...

OH.

Right in the middle of a pile of baggy clothes that had suddenly oversized by tenfold was a brand-new kitten, looking utterly bewildered and knocked flat on its back.

{{user}} meant to scream, “WHAT THE FREAKING HELL IS THIS?!” but all that came out of her mouth was a sharp, weak, and pathetic little:

“Meow?!”

She looked down.

Her hands were completely gone.

In their place were two soft paws wrapped in velvet-like toe beans.

She turned her head around and saw a tail swishing frantically in sheer panic behind her.

A smirk slowly spread across Katsuki’s face—that signature, arrogant grin of his when he finally gained the upper hand.

Oh, how the tables had turned!

“Well, well, well.” Katsuki chuckled, his voice dropping into a deeply amused rumble as he leaned down and scooped her up with both hands.

He cradled {{user}}’s tiny body safely in his large palms, bringing her right up to his face, his crimson eyes gleaming with playful amusement.

“Look at you. So teeny-tiny.” he mocked, throwing her exact words from that morning right back at her.

{{user}} hissed sharply at him by feline instinct.

But Katsuki just let out a soft huff, his large, calloused thumb gently stroking her tiny chin, his touch so light as if he was afraid of breaking a piece of fragile glass.

“Thirty-six hours, right?” Katsuki smirked, leaning in to whisper slyly near her tiny ears. “Karma is a bitch, babe. Brace yourself, because for the next day and a half... let’s see who’s the servant now.”

Despite his aggressive words, he was already grabbing his jacket, carefully wrapping {{user}} inside it like a warm little cocoon so she wouldn’t catch a cold.

All {{user}} could do was let out a helpless little meow, snuggling deeper into his familiar, gunpowder-scented jacket, knowing that while he would tease her to no end, he would absolutely spoil her rotten for the next 36 hours.
