It was just a run to the convenience store.
So how could it have possibly ended this terribly?
Midoriya was just going on a small errand run. The class needed some things from the convenience store, and it was his turn to do the shopping this week. He was more than happy to go, especially when All Might said he’d join him.
The breeze was nice, it hadn’t been very humid nor hot out. It was crowded–as it was the weekend–but not enough to be suffocating. The two were walking happily along the sidewalk, eagerly basking in each other's presence and company.
They had bought what they needed from the store, and were on their way out…
That’s when the incident occurred.
They had been talking about his progress with One for All–admittedly, they should not have been talking about that sort of thing in public–when suddenly they heard screams and shouts come from ahead.
As heroes, they knew to take public distribution seriously, and readily tensed for a potential oncoming fight.
What they didn’t expect however, was how close the man actually was.
And when the last few people backed away, the man ran straight into them, knocking both of them–including the man himself–down onto the pavement home-alone style. Knocking the breath out of both of them, they struggled to try and get back up.
“I’m sorry! I’m so sorry! I have to go! I’m sorry!” the man said, quickly staggering up before taking off again, leaving the two of them in the dust. The two quickly staggered to get up and chase the man.
“W-Wait! Stop!” Midoriya stammered, watching the guy get further and further from his vision. As he was about to start chasing him, he felt a plummet of pain enter his chest. He groaned, clutching his stomach as a cramp settled in.
His vision became foggy, his mind hazy, and his body felt weightless. When he turned to meet his mentor’s eyes, he realized right away that All Might was also feeling these strange effects. Soon, his vision became dark, and he didn’t even notice his body was back on the warm stone of the sidewalk when he passed out.

“Guy’s, Deku’s not back yet from his run...” Uraraka noted, staring out the window to look at the school grounds. “I’m getting a little worried, he usually never takes this long.”
“Relax Ochako, kero,” Tsuyu reassured, grabbing her shoulder for support. She, too, was looking out the window with slight worry.
“Yeah, maybe he’s taking longer because he and All Might are like this!” Mina said, having her pointer-fingers close together for emphasis.
Everyone was in the common room, as it was the weekend and nobody had plans. They were all scattered, some on the couch, some sitting on the ground, and some standing nearby. Even Bakugou and Todoroki were enjoying their time out in the main area, either talking to other classmates or waiting to make dinner.
Which is why they’re waiting on Midoriya, because he was supposed to bring the ingredients for dinner thirty minutes ago.
“Midoriya wouldn’t keep us waiting though? He certainly wouldn’t wait tonight either, considering it’s Katsudon night,” Ojirou informed.
“Do you think something happened? Remember last time he was late he got stopped by an anti-villain,” Jirou mentioned, making some people turn some heads.
“You mean, during the festival? That actually happened?” Sero raised a brow. Jirou simply nodded in reply. Some people looked to be in deep thought.
That is…until the door opened.
They turn to see their Aizawa come in, expression stern and looking at them with foreboding. It made them feel uneasy and tense. Usually, that face is held for certain occasions, where one of them is in trouble or when one is in danger.
There’s only one possible explanation for this.
Midoriya’s either in trouble or in danger.
Aizawa coughed in his hand as the students started huddling around. “I’m sure you all know why I’m here,” he started, looking around at all the tense and worried expressions.
“To put it simply, there’s been an accident regarding Midoriya and All Might,” Aizawa informed, continuing to look at them as they waited in bated breath.
“A man was running through some traffic on the sidewalk, whether he did this intentionally or not is still on the case, we’re still trying to find the suspect,” he said calmly. “Apparently, the suspect was in a rush to get somewhere, we have a description and some heroes are heading to where he was last scene-“
“Ah who cares! Just tell us what happened to them!” Kaminari shrieked, before flinching at the glare that was sent his way. Aizawa sighed as he continued.
“When he came into contact with some civilians, apparently they turned into cats,” he paused, watching as the students just blinked at him. “The detective currently has them in his custody, and they are in fact, cats. So don’t startle them, be calm because he’s bringing them here.”
…
“Yes sir.”
—
When he groggily woke up, the first feeling Midoriya felt was his head splitting from pain. He felt fuzzy, and it felt like everything was too much. He could hear the muffling of something or someone, but all he could feel was a major headache.
He whined, uncomfortable as he wiggled and tried opening his eyes. He could hear that the muffled noises stopped, however he was too focused on trying to wake up. He didn’t know why he felt so tired.
Suddenly, he felt the cool press of something cold against his body and he sighed, embracing the coolness. He had a strong urge to rub his head against whatever it was, which was a bit weird, but he normally burrows his head in his pillow so he didn’t think much on the matter.
Slowly, he opened his eyes, thankful for the semi-dark area he was in.
Until everything came rushing back in his head.
He tried flailing up to get ready for a fight, however it seemed his body was against him, as he just ended up wiggling around like a fish.
He didn’t know what was happening, and now that he notices, he doesn’t even know where he is. The sudden rush of panic made him scared—almost too scared for some odd reason—and when he was just about to get up again, he heard it.
A whine.
Not a normal whine—no. An animal whining, as if a cat was present and scared. He paused, wondering where the noise came from.
His ears perked up—he heard it again!
A whine, coming directly from him.
Midoriya felt frozen in shock and confusion. Him. He was the one making that whining noise.
Now that he realizes, he can’t exactly control his body properly. His senses are all over the place. And now that he’s really looking, it seems he's in the back of a car, but he’s so small.
He looked down.
And instead of seeing his normal shirt and shorts, with human arms and legs. He saw green and black fur, cute fluffy paws, and he could feel a small tail wagging.
He was a cat.
No, not just a cat. A kitten.
He turned into a kitten!
In admits of his shock, he didn’t realize he had company. That is, until he heard someone.
“Young Midoriya! My boy!”
Midoriya turned to see All Might, except instead of his usual human body, it was a very large, lanky yellow cat. With the iconic two strands of hair—or fur in this case—in the front of his head. Midoriya felt incredibly happy, trying and failing to walk to the man.
He gave a small mew, “All Might!”
He saw as All Might trotted over to him, gently sniffing the top of his head before oddly enough—licking it. They both froze, and if Midoriya was human, his face would be red from embarrassment at the fact that his new cat body started purring
All Might broke away from his head, huffing in embarrassment as well. “I-I apologize young Midoriya, I did not know what came over me.”
“I-It’s okay,” Midoriya stammered, feeling flustered. Then, he heard the chuffing–or giggling–of another cat. He turned his head to see seven other cats.
If he was human, his jaw would drop.
There, in real time, were the vestiges of One for All, as cats.
“W-What!” Midoriya yowled, accidentally stumbling.
“Hello, ninth,” a plump, black cat strutted over to him. Gray eyes look at him and he feels that if she were human, she’d be smiling. “How wonderful to get to see you in person,” she said calmly.
Then, she licked the top of his head. Embarrassingly enough, he once again started to purr.
He looked at the remaining people–cats. There was a fluffy white cat, a spikey pink cat, a spikey cyan cat, a greasy yellow-ish cat, and a sphynx cat. The first, second, third, forth, and fifth. Midoriya’s eyes couldn’t have popped out of his sockets any more.
“I-It’s you! T-The-!” Midoriya couldn’t even speak, it was like he was meeting celebrities.
The white fluffy cat–the first! Midoriya can’t believe it!--chuffed and skittered a little towards him, only to flop his head on him, knocking him down on the seat.
“Ninth! It’s so exciting to finally be able to meet you!” he said happily, continuously rubbing his head on top of his. Midoriya felt a little flustered at all the attention, as well as the giddy feeling he gets from the first essentially petting him.
The first decided head rubs weren't enough, and decided to start licking the top of his head, resulting in loud purrs from Midoriya.
“We don’t know how we're here, but we’ve come to the conclusion that it was due to our essence within the quirk that allowed us to also be affected by this quirk,” the Second stated as he watched the two, walking closer.
“W-where are we going..?” Midoriya asked sheepishly, a little intimidated with the second and his stern gaze.
“Tsukauchi is driving us to Yuuei right now,” All Might stated, also being subjected to licks from Nana Shimura.
“How are we going to hide all of us? His classmates will surely know something suspicious,” the fourth stated.
“Kacchan knows about One for All, maybe the detective can give all of us to Kacchan until this is over,” Midoriya said through purrs.
“Good idea Ninth,” the sixth praised, making Midoriya purr even louder.
When the car came to a stop, Tsukauchi looked over towards them, and gave an amused smile as he saw the nine cats in a cuddle pile.
“Alright, is there any way we can hide…whatever this is?” Tsukauchi asked, wondering if he would even be able to communicate with them.
All of them turned their heads to him, either blinking, meowing, or glaring at him. He sighed, “I’ll text Nedzu to see what we can do,” he told them, before doing just that.
—
“I can’t wait to see them as kitties!” Mina squealed, holding hands with Hangakure as they cheered.
“Koda, maybe you’ll be able to speak to them!” Kaminari exclaimed. Almost everyone from the class–save from the stone-faced classmates–had stars in their eyes.
Bakugou, sitting on the couch, was watching the chaos before he felt his phone go off. When he went to check, his eyes narrowed at the unknown number and quickly left to get privacy.
“Who’s this?” he asked when he picked up the phone.
“Hello, this is Tsukauchi from the police department, is this Bakugou Katsuki?” he heard from the other line.
“You can cut the fuckin’ smart talk, you called cause of the two idiots hah?”
He heard a cough on the other end. “Yes, this is also about One for All, I was told you’re aware of their shared quirk?”
“Yeah, what’d they do, does this have to do with the damn cat quirk?” he said gruffly.
“Yes. The past vestiges are also here…which is why I’m calling you,” Tsukauchi says.
…
“Hah?”
“We don’t know exactly how this happened, but now we have nine cats that can’t get out to the public. I was wondering if you’d be okay with having custody of them all until the quirk passes, since Nedzu said you knew about One for All,” Tsukauchi explained.
Bakugou sighed, “yeah sure, I’ll meet up with you to smuggle them in, but leave the other two ‘cause the class is already waiting for them to get here,” he stated before hanging up and heading out through the balcony.
If he was honest, he was quite curious to see the previous vestiges of One for All. He’s also not sure how well this meeting will go.
—
The class heard the doors open and sprung up from the couch. There was Aizawa and Tsukauchi, with a metal crate in hand.
“Is it them?! Is that Midoriya and All Might in there?” Kirishima shouted.
“Yes,” Tsukauchi stated, “they’ll be like this for some time, only for the day. We got the man who caused this and he gave us some information. They can eat human foods, but can only drink water or milk. Don’t startle them or overwhelm them.”
With that, he left. Aizawa gently set the crate down, and the class got closer. Aizawa lifted the door open and in a blur of speed, the two ran out of the crate and straight into the open common room.
The class squealed.
They-! They’re so cute!!
“Hi Midoriya-!” Momo lured gently, raising her hand for him to sniff.
‘This is so weird. I know they're my friends yet I can’t help but feel scared,’ Midoriya thought as he sniffed her hand before rubbing his face on it. He developed into purrs as her hand petted his head.
“Arg! I just– the cuteness aggression!” Mina strained, hands gripping her hair.
All Might was merely watching everything, making sure Midoriya was safe and not injured. Despite the two of them trying to avoid their new cat instincts, it was unavoidable. His tail puffed up in alarm when Uraraka slowly came up to him.
“Umm, guys, All Might is getting nervous,” Uraraka noted. Some looked over to see him, whipping his tail and ears pulled back into the infamous ‘airplane ears’ style. They backed off Midoriya a little, watching as All Might crawled over to him and grabbed him by the scruff.
“Does this correlate to my secret love child theory?” Todoroki deadpanned, watching as All Might brought the two of them over to the couch where he and Bakugou were sitting nonchalantly.
All Might jumped up and let go of Midoriya’s scuff. Todoroki, in an act of bravery, reached his hand out to All Might to sniff. The older cat sniffed a little before rubbing his body along the hand, allowing Todoroki to pet him.
“Now I want a cat,” Todoroki said, unprompted as he continued to pet All Might.
“Awww-! Why does Todoroki and Bakugou get all the attention!” Jirou pouted.
While Todoroki had All Might’s attention, Midoriya scurried onto Bakugou's lap and curled in it, purring loudly.
Bakugou tch’ed, “spoiled brat.”
“Pot met kettle,” Sero teased.
Bakugou simply started scratching his chin, making him become a lawn-mower with how loud his purrs became.
“I don’t want them wandering around the common room, so someone will have to put them in their room,” Aizawa informed, making hands spring up in volunteering.
“I will,” Bakugou stated, not even looking up from his phone as he continued petting Midoriya, who was making air biscuits from how blissed out he was.
“No fair! I called dibs first!”
“Shouldn’t Kouda have them?”
“They might attack my rabbit.”
“Why does Bakugou get them!”
“Silence,” Aizawa stated.
…
“Bakugou will keep them, simply because I don’t have the energy to argue with you all. Midoriya and All Might are clearly familiar and comfortable with him, so he gets dibs,” Aizawa said, words final.
The class sulked while Bakugou had the biggest grinch smile on his face.
“I’ll take them up now, teach,” Bakugou informed before getting up, putting Midoriya on the couch. All Might, knowing to follow him, grabbed Midoriya by the scuff and scurried to follow Bakugou.
“Ya’ll need to stop getting into trouble. I swear you’re not even bothering to try and hide it,” Bakugou complained as soon as the elevator shut. All Might huffed and rubbed his body along the blonde's leg as a quiet apology.
Midoriya wished he could apologize, however all that came out was a quiet mew.
“The others are in my room,” Bakugou confirmed as he watched All Might scurry ahead of him and wait patiently at his door.
When he opened it, he was barely even able to walk in as the clowder of cats took up the floor, meowing or scampering around.
“Jeez,” he murmured as he shut the door.
Taking the seven vestiges up to his room was surprisingly easy. He was expecting them to be wary, maybe hiss or growl. A few glares directed at him but no. Instead he thinks they were quite comfortable around him. They listened to him and some even crowded around him for pets.
Now it’s like they all got a taste of cat nip, and the good shit too.
“Calm down,” he gruffed out, watching as they all decided to stake claim to his bed. The white one continuously licks Midoriya on the head. The pink one by his side acting like a body guard. It was quite the cuddle party.
“This is weird as fuck,” he just stated as he sat on the bed with them. Midoriya waddled to him and flopped on his lap, clearly enjoying having his attention.
“Oi, you little shit. You’re enjoying this huh?” Bakugou snickered.
Then surprisingly, the white one–he doesn’t know who’s who–slowly came onto his lap to get to Midoriya, still urging to lick his head. Now though, he started licking Bakugou’s hand.
Bakugou sighed, looking at the others who were watching the two. He swears he can feel the menacing gaze of the pink one on him.
“You all hungry at all?” Bakugou asked, getting some meows in reply. He’ll assume they are hungry, so he tries to get up. Only for the pink one to pounce on his arms and bite, a firm demand to stay still.
“Ouch you fucker!” Bakugou groaned.
“Kudo…please don’t hurt him,” the first asked gently, pausing his licks. Frankly, he was quite happy to get a second chance at life, even if it was only for a day. He was excited, he got to meet the eighth, the ninth, and the honorary One for All user! So it wasn’t like he could control his animalistic instincts now.
“Fine,” the second–Kudo–stopped.
“I am hungry…” Midoriya mumbled, “Kacchan was supposed to make Katsudon tonight,” he whined.
“Oi, what’cha whining for?” Bakugou looked at him as he crawled out of his lap to lay on the bedding. “I’m getting food, stop complaining,” he grumbled before leaving.
Since he couldn’t make Katsudon he just made something simple with meat. It was a pain in his ass to cook and have everyone asking him questions. It was even more of a pain to sneak seven extra plates to his room for the others.
When he came back, they were all scattered around his room. One was sleeping in the sunray by himself, and two–a black and bald one–were together meowing. Midoriya and All Might are being licked by who he assumes is Nana Shimura on the bed. The same thing is happening to the white one, being licked by the pink one while another cat is sitting next to them watching.
“Food,” he announces, watching as Midoriya perked up. “Not Katsudon, since someone had to turn into a cat rather than get cutlet,” he informed.
Midoriya whined.
Dinner was a quiet affair. Everyone was happily eating away, especially Midoriya who always loved when he cooked. When they finished, they all cuddled up on his bed in a big cuddle party. He huffed, that’s when he thought of something horrible.
“I swear to whoever’s up there, if I wake up to find you both naked I’m going to blast you both into atoms.”
Both Midoriya and All Might yowled in embarrassment, urgently shaking their cat heads to say ‘no!.’
“Alright good,” Bakugou got the message and hopped into bed.
He never would have thought that he would be going to bed with nine cats along with him. Cats who are actually ghosts and the vestiges.
What the fuck is his life.
—
In the early morning, Bakugou thankfully did not have to see the two naked in his room after turning back into humans. It was around the time he went for his morning run when the two woke up due to his movement.
“Ah, Kacchan…” Midoriya murmured, still heavy with sleep, “thank you for helping out with the vestiges.”
“Whatever, stop getting into trouble–both of you,” he huffed, though the two could see a little smirk on his face. “You were cuddly as shit, nerd,” he teased.
“Kacchan…” Midoriya smiled as they left the room.
“Yeah yeah, but turn into a cat again and I’ll pluck your whiskers off!”
“Wahhchan!”
