USJ Incident

*Warning- SA scene ahead, may be triggering for some readers. You've been warned.* Also timeline is slightly changed for this part for the sake of the story.

Pulling up at a large domed building, Luna took off her headphones and placed them with her phone under the seat. She sat still and let everyone file off the bus ahead of her. She didn't particularly feel like talking to anyone right now, so she let herself off last. Standing at the back of the group, she listened as Mr Aizawa introduced them all to the pro hero 13.

"Hello everyone, I've been waiting for you!" She said, Luna listened to her classmates getting excited. Especially when Izuku started describing her. "She's saved people from disasters across the world!"

As they all entered the building, 13 explained this facility was created specifically to teach how to handle different types of disasters. Fully equipped with shipwreck zones, landslides, squall zones, and many others, it was dubbed Unforeseen Simulation Joint, or USJ for short.

"Before we begin, listen carefully," 13 began, "I'm sure you're all aware I have a powerful quirk. It's called Blackhole, I can use it to suck up anything and turn it into dust. While I have used it to save many people, my quirk could very easily be used to kill. Some of you also have powers that can be dangerous. Although quirks are heavily regulated in this society, please don't forget all it takes is one wrong move to make your power deadly. Today you're going to only be saving lives, you won't be attacking enemies or each other. You're only going to help. That's what being a hero is about, ensuring the safety of others. That's all I had to say, thank you all for listening and good luck out there." 13 finished her speech and everyone clapped, smiling up at the pro hero.

"Right. Now that that's over." But before Aizawa could finish his sentence a power surge ran through the building. The water in the fountain began to start and stop, and in the middle of it a purple portal appeared.

"Stay together and don't move. 13 protect the students," Aizawa ordered as people began walking out of the portal. 'This is bad,' Luna thought, 'those are real villains.' Mr Aizawa only confirmed her assumptions by voicing her thoughts. "This is real, STAY BACK." Luna and her classmates watched as the purple villain mentioned retrieving a schedule from UA. "So they used the press as a cover for sneaking onto campus." Aizawa surmised.

She watched as more and more villains poured out of the portal. The villain with hands all over him spoke about wanting All Might. "Maybe if I kill a few kids, he'll come out to play." That was when Luna realized she and all her classmates were in serious danger. Everyone began asking questions all at once.

"How did they get in here?"

"How did they get past the sensors?"

"Why aren't the sensors going off?"

It was Todoroki that answered the last one though. "They've obviously got a villain who's masking their presence here. Whether it's the whole campus or just this one facility, they planned this. This area is secluded and further off, they were fools to come here at all, but they have thought this out. Whatever their plan, they must have a concrete objective in mind. But what is it?"

Luna had an idea but before she could say anything, Mr Aizawa spoke. "13 get the kids out of here and alert the main campus. Kaminari use your quirk to try and contact the school. They may be jamming regular communications." Izuku stepped forward trying to talk Aizawa out of fighting, since he specialized in stealth, not group combat. "You can't be a pro if you only have one trick Midoriya." Aizawa leapt into action, using his scarf as his weapon he cancelled the quirks of three villains immediately and slammed them to the ground knocking them out cold. One after another the villains came at him. Watching Aizawa masterfully dodge every hit and counter with his scarf was incredible, but there wasn't time to sit there and wait.
