Trouble always strikes when you are least expecting it. Like a monster of doom, invisible until the moment of contact.

(And no, this is not a Hunter X Hunter reference). 

That was the lesson they learnt that day.

During their USJ trip.

KK was struggling to stay awake, considering that she was the Class Representative and everything. Momo was teaching her how to play Sudoku. She found it interesting, and soon enough they ended up competing against each other to see who could solve a puzzle the fastest. Momo won, but KK didn't specifically mind.

On the other hand, Axel was trying her hand at a decent conversation with Bakugo. Bakugo had apparently realised that she wouldn't leave him alone, also that she wasn't Deku at the same time. So now it looked like a one-way conversation interjected by his grunts.

Todoroki was looking around with an almost bored expression on his face.

Izuku was shaking slightly. Field trips always ended up in scorch marks for him.

"My name is Tsuyu Asui, but you may call me Tsu-chan," Tsuyu began, "And I always speak my mind, so please tell me if I am being insensitive. Makoto-chan, I have observed that even though you do call Axel your sister, both of you have different surnames."

KK looked at her, and answered before Axel could.

"Well, our parents separated when we were rather young, so it led me to taking my father's title and she took mom's. Not like we had much of a choice. Both of them are dead now, so we have to look after each other, but provided that we are used to these surnames, it felt weird to do otherwise."

She bit down her nervous laugh and resolutely ignored Todoroki's raised eyebrow. A few sympathetic murmurs rang out in the bus. Ochaco patted their backs.

Tsuyu gave her a look before latching onto Izuku.

"Your Quirk looks pretty similar to All Might's."

KK resolutely looked down. Hacking gives someone a lot of information, provided you hack the right place. Along with a fair bit of stalking.

Todoroki looked up at this statement, suddenly taking an interest in the situation.

"All Might doesn't break his bones though," Axel began, "They are already different in that way. Even though All Might seems to favour him quite a bit."

"Yeah, true that. Probably just the partiality of a teacher, though," KK commented, "He might be the Number One Hero and Symbol of Peace, but he isn't exactly all good and nice. All teachers have their favourites."

"Yup, like you are Aizawa sensei's favourite," Kaminari jabbed in, to which she rolled her eyes.

"I fail to see how you arrived at that conclusion, Denki, but I can assure you that it's not the case."

"It's the vibe, dudette, the vibe," he said as if preaching a religious text. She snorted.

"Hardly. I wouldn't waste my breath to correct your misconceptions, so proceed with your conspiracy theory involving All Might and Izuku."

Todoroki did sit up a little straight at the term "conspiracy theory."

Secret love child, I bet.

"Not much. But hey, that kind of super strength is cool and flashy, though. Unlike my hardening, which is super boring in a fight," Kirishima said from his corner.

"It's more than enough if you want to go pro!!!!!" Izuku said, thankful for the topic change.

"Yup. But you have to keep in mind the fact about popular appeal if you want to go pro," Mina said.

"My Quirk is flashy enough for that," Aoyama butted in.

"As long as you don't blow up your own stomach," she said.

He looked slightly sick at that.

"You wanna talk cool and strong? That would be KK, Bakugo, Todoroki and Axel," Jirou said. Axel visibly brightened when her name was mentioned, a grin making its way onto her face.

"But Bakugo is unhinged. He will never be popular," Tsuyu pointed out.

Which caused him to snap.

"WHAT ARE YOU TALKING ABOUT, FROG FACE????"

Axel smacked him on the head, causing him to glare at her. If glares could kill, she would have been ash on the floor. On the other hand, her glare looked like fire was shooting out of her irises.

Kacchan's being bullied, who would have thought.

Izuku's anxiety did nothing good for him, as he began shaking. He really hoped that they wouldn't kill each other in the bus.

"We have only began socialising and you have made your unpleasantness of a steamed turd of a personality abundantly clear to us," Kaminari said.

"WELL OKAY, MR. VOCABULARY, HOW ABOUT I POUND YOU?"

"How about you stop yelling like a maniac?" Axel snapped.

"HOW ABOUT YOU STOP FOLLOWING ME?"

"HOW ABOUT YOU STOP FOLLOWING ME?"

"I AM NOT FOLLOWING YOU, CAT EARS!!!"

"SAYS THE PERSON WHO DECIDED TO KEEP YELLING ABOUT BEING IGNORED WHEN I REFUSED TO SPEAK TO HIS SALTY ASS AFTER THE QUIRK APPREHENSION TEST."

"I DIDN'T FUCKING DO THAT, I WILL FUCKING BEAT YOU, CAT EARS."

"Dream on, Cat Face."

The screaming contest continued until they reached USJ.

"What a vulgar conversation," Momo mumbled.

KK shrugged.

"It's pretty hilarious."

"I agree," Ochaco said with a grin.

"IS THIS UNIVERSAL STUDIOS JAPAN." Sero exclaimed, looking around the place.

"Welcome, welcome. I built this place myself. It has training stimulations for every possible rescue situation. I call it.....the UNFORSEEN STIMULATION JOINT!!!"

Everyone gaped at Thirteen, the Space Hero in awe.

Uraraka was jumping up and down in glee and Izuku was onto his fanboy rant. KK was possibly the only one who looked disinterested. But then again, she always looked that way, as if everything was a chore, including smiling at times.

Even Todoroki himself was looking invested in Thirteen.

"Thirteen, where is All Might?" Aizawa asked, irritated.

"About that," Thirteen said anxiously, holding up three fingers, "He has reached his time limit so he will be unable to attend."

Aizawa growled.

"The height of irrationality."

He turned back to the students.

"Let's get started then."

Thirteen took over from there.

"Before we begin, I have a few points. As many of you are aware, my Quirk is called Black Hole. It can tear apart anything and suck it into my fingertips. It is a dangerous power which could be easily used to kill. I have no doubt that there are many of you with similar abilities. In this superpowered society, the use of Quirks is heavily monitored. It might seem a stable measure, but never forget that it takes one wrong move with an uncontrollable Quirk for people to die. During Aizawa's fitness test, you all learnt your respective potential. During All Might's training, you all learnt about how your respective Quirks could pose a danger to others. During this one, you will learn about how to use your Quirks to help others. Your powers aren't meant to inflict harm. After this, I hope that you all can leave with the understanding that your powers are meant to help others."

KK stifled a yawn.

Yeah, yeah, all heroic speeches and actions. Of course, all that jazz.

"THAT'S IT!!! I THANK YOU ALL FOR LISTENING!!!" Thirteen finished with a bow.

"Great, now first—," Aizawa began, but he got interrupted by a huge portal opening in the middle of the Joint, near the fountain.

Purplish black.

KK immediately took out her scythe and yelled, "RUN," before either hero could speak. Aizawa put on his goggles and turned around.

"HUDDLE UP AND DON'T MOVE."

KK could have taken his head off in her panic.

Suffocating.

Pain.

Drowning.

Dying.

"THIS MIST, IT IS A PORTAL— PORTAL QUI—QUIR—QUIRK," KK was half stumbling over her words in a hurry to get out of this situation, "HE CAN TELEPORT YOU ALL WHEREVER HE WISHES, HUDDLING UP WOULD GIVE HIM AN ADVANTAGE."

Twin flames glowed in Axel's hand. KK's stuttering and her description of a purplish black portal fitted with the situation perfectly.

Her eyes glinted.

They were so dead.

Aizawa seemed to hear her and then called out.

"THIRTEEN PROTECT THE STUDENTS!!!"

KK hissed and brought down her scythe to protect her middle. The world was beginning to blur. She could only hope that she didn't lose her footing.

Behind her, the class was still confused.

"Is this another stimulation?"

"NO, YOU FUCKERS, THEY ARE REAL FUCKING VILLAINS," KK snapped, pushing some of them back.

"Thirteen and Eraserhead, is it? According to the description we received earlier All Might was supposed to be here," the mist villain spoke.

"All Might? Is he...here? We brought so many playmates....."

The chilly voice was made her blood turn to ice.

"Ah, Tomura, I did not anticipate your arrival."

".......am I interrupting?"

"Not at all, look, I am running an experiment."

Blood.

Hands.

Death.

The scythe suddenly felt too heavy in her hands, the world was a swirl of colours. Faintly she could hear Aizawa calling out orders and a burn and ice made her snap back.

"M'sorry," she mumbled to Todoroki and Axel, focusing on the situation at hand. Her right arm was still stinging, but it was better than panicking. Slightly, because her vision was still swaying.

"Aren't there intruder sensors?" Momo frowned.

"Of course there are," Thirteen said, but he wasn't sounding too sure of himself.

"Are they at the main building as well?" Todoroki frowned, "Either way, if the sensors aren't working, then it has to be one of their Quirk which is doing it. This place is far from the campus, and they specifically picked a time when there would be least people in here. So they are perhaps not as dumb as they seem, this is a well coordinated sneak attack. They must have an objective."

"Yeah, killing Mr. Paragon of Virtue," KK said, "And if you can see that heavily musculared guy there with a beak, steer clear of him. He is Number 2 on the danger list."

No one questioned how she knew it.

"Thirteen, begin evacuation and try calling the school. One of their electric types have jammed the signals, so Kaminari try giving a signal with your Quirk."

Kaminari looked flustered at the sudden command.

Meanwhile Izuku was talking to Aizawa.

"BUT SENSEI, YOU CANNOT FIGHT THEM ALL ALONE, ERASERHEAD'S FIGHTING TECHNIQUE INVOLVES ERASURE AND A QUICK CAPTURE!!! YOU CANNOT ERASE SO MANY QUIRKS!!! EVEN IF YOU DO, YOU STILL HAVE TO FIGHT THEM."

He got a beseeching look in return for that.

"No good hero is a one trick pony. Thirteen, take care of the students," he said before jumping right into the foray.

He managed to get thirteen villains down as Izuku was gaping in awe.

"Wow, even while being outnumbered he is so good."

"Izuku, now isn't the time for analysis," KK said, half dragging him back, probably scoring a few cuts on his arm with her grip.

Her heart was racing. She didn't want to be here. UA was supposed to be safe, not this crap. No one said that Kurogiri would end up here to say hi. She could only hope that they hadn't noticed her.

However, luck was never on her side as Tomura's eyes caught sight of her. She shouldn't have yelled so much at the beginning.

"Sensei said that she was dead," he frowned.

"He also said that she might be hiding amongst the UA students this year," Kurogiri replied, before shifting right behind them as they prepared to evacuate.

"I WON'T LET YOU," he rumbled, tendrils of mist reaching out to encompass them. KK shrunk back and took the centre, putting her scythe away before she accidentally dropped it on someone.

Thirteen opened his Black Hole, proceeding to suck the mist off Kurogiri.

Before KK could tell him that it was a horrible idea, Kurogiri formed a portal behind him and turned his Quirk against him.

Thirteen fell to the ground, his suit broken and spine injured.

And then there was chaos.
