The girls hear Mina's scream; they've changed to.

"AHHHHH!" Mina screamed, horrified at the reflection that stood before her.

Somehow, overnight, her nose had transformed into that of a pig's and there was no explanation for this.

Could this have been somebody's quirk affecting her? Maybe, but she couldn't think of anyone that had a quirk that could do something like this. Plus, Mina had not even been off school grounds nor met anyone new yesterday. So, she was at a loss.

Suddenly, she heard a fast-approaching commotion outside her dorm room. Fastly shuffling feet and concerned, muffled voices arrived at her door.

"Mina," She heard Momo speak, "We heard you scream. Is everything alright in there?"

Hastily, Mina tried to quell their concern, kicking herself for having drawn so much attention by crying out.

"Uh... Yeah. I'm okay. Just... uh."

"We're coming in, okay?" She heard Tsuyu say, causing the Pink Pig girl to blunder and panic.

"NO! DON'T COME IN!"

It was too late however, as her cries fell on either deaf or uncaring ears and the door to Mina's room came open, revealing Mina in a state of anxious desperation.

Mina was so flustered that she had not noticed how the girls somehow bypassed the door's lock nor had she processed the truly bizarre view in front of her.

Before her, Mina saw Momo's head and upper torso emerge from around her door. The majority of her flesh was completely exposed, except for a pair of bikini top and bottoms. Strangely, the pattern of this bikini was a splotchy black and white, resembling a cow. And, terrifyingly to Mina, Momo's head seemed to now be sporting two little horns atop her head and, hanging from her ear, lay a small yellow piece of plastic that looks awfully like a farm tag.

"Y-yao Momo," Mina managed to squeak out, hiding her new nose behind her hand, "What? It happened to you, too?"

"What happened to me? What do you mean?" Momo asked, her head tilted in inquiry, moving into the room.

The other girls followed her in, showing clear worry and curiosity for their friend.

Mina finally noticed something and, again, asked, "How did you even get in here, anyway? I thought my door was locked."

"Huh?" she heard Jiro's voice say, "Girls' dorms don't have doors that lock. You know that?"

Mina definitely didn't know that. Because it wasn't true.
What really struck Mina was how nonplussed Jiro sounded, as though she had said something so ordinary and unobjectionable.

It wasn't long before all of the girls had entered Mina's room, to check up on their dear friend, who was now backing up and dutifully pressing both hands to her piggy face, too ashamed to be seen.

Her concerns quickly shifted, when she saw the rest of the girls, though.

Mina had ample opportunity to see them all now and... WOW, she was not sure what to make of it.

All of the girls were wearing bikinis of various types and colours, ranging from standard, comfy to a flat-out string bikini or a set that's see-through. Also, Mina actually had to take a moment to recognise Toru, who was now completely visible to her. However, that wasn't the worst of it. She found that they all, with the acception of Tsuyu and Toru, had some sort of animal themed augmentation.

Momo had cow horns; Jiro had bat ears; Ochako had cat ears and feline eyes. That, plus her pig nose, made four. Mina guessed that, Tsuyu having a frog mutation quirk anyway, may have been immune to whatever was affecting them now. Toru, however, Mina had no clue.

"What?" Mina began, feeling feverish and sweaty, "What are you guys wearing?"

"What do you mean? Ribbit," Tsuyu said, looking down at her green string bikini, completely unfazed, "We're just wearing our uniforms. Why aren't you wearing yours?"

"Nyou don't look so good, Mina," said Ochako, closing the gap between them and placing her forehead onto the pink girl's, "I hope you aren't sick, nya."

"Nya!?" Mina repeated, confused.

Were the girls completely unaware that they've got animal parts stapled onto them? Why weren't they acting as jarred as she was?

"She's probably just hungry," Jiro said, folding her arms over her head, nonchalantly, "You know Mina."

"ARE YOU SERIOUSLY ACTING LIKE NOTHING'S GOING ON!?" Mina yelled, before the room was filled with a too audible grumbling and Mina's priorities shifted somewhat.

"Actually, I could... really go for some food right now," She said, her hands slowly being lowered and freeing her new, foreign snout, which began twitching at the promise of a big meal.

Maybe some food will make her feel better... yeah, probably.

"Yeah," Toru said, jumping up cheerfully, "Let's get some grub in us."

Mina was about to second that, wholeheartedly, but she was able to shake herself back into awareness.

No, she had to focus.

"Hagakure," Mina inquired, "I'm being stupid here but... what was your quirk again?"

The room held a silence before the other girls laughed.

"Mina. You're so silly. You know. I'm part-chameleon. I can blend into my surroundings and even make myself invisible. See?" said Toru, as she demonstrated her quirk by disappearing and reappearing back. Her see-through bikini even modified with her, Mina noted.

So there were:
Jiro - Bat
Momo - Cow
Ochako - Cat
Tsuyu - Frog (no change there, thankfully)
Toru - Chameleon,

... and she got Pig.

"WHY THE FUCK DID I GET PIG!!!" Mina yelled to the Heavens.
