3rd Persons POV

Everyone, one after the other, walk in to the USJ, their eyes wide from amazement. Except Katsuki. He's just not so good at... showing emotions. Except anger. We all know he's good at that.

All of their eyes go over the different obstacles built inside the huge dome. Hues glistening beautifully. Suddenly, Thirteen [ok, idk thirteen's gender cuz it's unknown so i'll call thirteen ,,They"] walks up to us, waving a hello.

After introducing themselves they... say this, "Also, I have one more thing to say. Well actually two... or maybe three? Possibly four." everyone sweatdrops at them, having the same thought in their minds.

"We get it."

"Okay okay, as you know my quirk is called black hole. I've used it for rescuing people from dangerous situations." Izuku and Uraraka nod uncontrollably fast at their statement. Uraraka and Midoriya have been fans of Thirteen for a while, admiring their capability to save others. How much more cuter can they get? "But it could also be used to kill."

Suddenly, the atmosphere got a little bit darker and... heavier. The thought of the heroes beside them killing an innocent civilian is just.. horrid. After that thought everyone continued to listen closely to anything else Thirteen had to say.

"I'm sure any of your powers can also be used as weapons to kill. And that's why we're here. We've prepared ,you children, obstacles of different situations. You know, all that jazz." everyone kinda sweatdroped again at that last statement. Aizawa looks lazily towards the student's direction.

"Okay, now that that's over-" he gets cut off by the light of USJ turning off.

Something... odd appears by a fountain in the middle of USJ. Looks to be some sort of portal or void. Aizawa gasps and turns around, looking at the unplanned attraction. He then puts on his glasses, shielding his eyes and standing in position to attack. Izuku notices this and breathes out deeply.

"Thirteen, keep the students safe." the dark haired teacher said.

'What's going on?'

Everyone thought. Suddenly, Kirishima loudly shouts to everyone, "Has the training already started? I thought we were rescuing people."

Aizawa turns his head back at Kirishima and lets out a groan. "This isn't training. Those are real villains." all students let out small gasps, their eyes wide from shock and fear.

'What do we do?'

Out of the portal walks out Tomura Shigaraki. The known 'leader' of the league of villains. Those hands on his face and body, send chills down everyone else's bodies. As he rose his hands up in the air more villains started to walk out of the portal. All wearing different costumes and looked differently, some were familiar than others, which were completely new. Iida takes a step back,

"We need to inform the other heroes! Ask for help! You won't be able to defeat them on your own!" he says, mostly towards the adults. Thirteen looks at him, approaching Iida and then putting their gloved hand on his shoulder.

"You're the class rep, right? Go. Notify any nearby heroes and send them here. As fast as you can." Iida felt like he didn't want to make things more difficult, so he listened and ran off, leaving everyone else still inside.

There are almost over 70 villains, as Katsuki counted. Why where they here? How did they get in without the alarms going off?

Then, a brief conversation was heard between Shigaraki and the portal.

"The only real heroes I see are Thirteen and EraserHead. But by our known information, All Might should be here as well." The portal informed with it's deep and almost tired tone.

"I want All Might. I want him to come out and play. Maybe, all I need to do is kill a few kids and then he'll come out?" Shigaraki's scratchy and wicked voice asks. Shota uses his scarf [or whatever that is] to get into position, threatening the other weaker villains.

And then........... an unexpected turn occurred.

As Tomura Shigaraki snaps his fingers a ginormous specimen walks out of the portal. It's purple.. has a muscular body and on it's neck is a long chain that continues back into the unknown void. Its brains seem to be visible and its eyes are... how to explain... Gruesome. Terrifying. Synonims. All at once, every single student, including the teachers saw something they couldn't unsee.

Another hand reaches from the void, holding the metal chain tightly and stepping one step at a time out of the dark hole. It slowly revealed a student wearing the U.A uniform, but a gas mask over their mouth [kinda like Toga. I like Toga <3].

When reality hit them, it was too late as the villains ran towards the group of people, the students, starting to attack from a distance.

What they saw...

What Katsuki saw...

(Y/n).

Katsuki groaned loudly and started approaching the other villains, ignoring Aizawa's shouts he ran, passing by every one of them, until realizing that he and (Y/n) are now 7 feet in front of each other.

They stare deeply, not noticing the fact that there are a bunch of villains around them, Shigaraki not too far as well. After a few minutes of an intense staring contest Katsuki finally speaks up,

"What the hell do you think you're doing?" by this point, Katsuki was confused as hell. (Y/n) looked at Katsuki with teary eyes and sniffed her nose.

"I'm doing this for my family.." she quietly says.

(Y/n) is still here. There's still a tiny piece of her left. A tiny piece of her heart still... alive. But Bakugou didn't think of it like that. All he knew was that (Y/n) is now working with the villain.

Katsuki's feet start moving towards (Y/n), faster than ever as he lifts the girl by her collar.

"WHAT THE FUCK DO YOU THINK YOU'RE DOING WITH THE VILLAINS? EXPLAIN BITCH!" he shouts right in her face. A wave of shock runs through (Y/n) as she lowers her head to the ground, gripping Katsuki's hand with her own, scarred hand. She lets out a shaky breath.

"I did this because Shigaraki said I'll get my sister back this way." that sentence made Katsuki's hands loosen their grip on the girl.

"Sister? Sister?! How could you even trust that ass?! Those assholes would never keep an outsider in their territory! She's probably already dead!" Katsuki shouts yet again. It hurt his stomach to, but he needed to show her the light.

But all that (Y/n) saw was the void... hearing her beloved person shout at her like that... and to say something this... cruel. It made her stomach clench.

She felt how her heart is holding onto its last string.

"You're never going to save her!"

Snap.

The last string snapping in half, releasing (Y/n)'s heart and letting it crumble into pieces.

A small chuckle leaves (Y/n).

Katsuki's hues shrink at the action. He completely lets go of her collar. (Y/n) still looking down, falls to the dirt ground and starts to laugh.

Laughing and laughing... until it becomes hysterical. This action of hers reminds Katsuki a little moment from back a few months ago. That memory.

"That's it. You broke her." Shigaraki speaks over her laughter. Katsuki, shaking, turns to Tomura and grinds his teeth against each other. He says this while charging at him,

"You motherfucker!" Katsuki's voice now deeper than ever, he takes Shigaraki by his wrists.

"Whoa whoa whoa there~ Now why are you attacking me? You're the one who did this to her." By this moment, (Y/n) already stopped laughing, calming down a bit and Katsuki noticed. But before he could look back and check, a sharp weapon reaches his neck, keeping him in place.

Suddenly, warmth expanded through his whole back and he felt something soft and squishy. (Y/n) is pressing herself against him.

Katsuki screams at himself in his mind to get his thoughts out of the gutter.

[boys amirit?]

(Y/n) pulls on one of Katsuki's ears and pushes him closer to herself, her head on the opposite side.

"I wonder what color your blood is~" she seducingly whispers in his ear, while pressing the sharp weapon closer to his neck. A line of bright crimson red blood spills out, making Katsuki groan.

"What's going on with you?"
