•(Y/N) (L/N)•

As the next day arrived I spent the whole morning going over what I could do depending on where I was sent to by Kurogiri. All Might wouldn't arrive for a while, and everyone managed to take care of the villains on their own.

Only Thirteen and Mr. Aizawa were drastically hurt.

Thirteen is able to recover, however Mr. Aizawa's eyes are affected drastically. He has to be my priority.

I was so busy thinking that I wasn't paying attention in class. Eventually Mr. Aizawa entered and Shoto nudged me to get my attention.

"Today's training will be a little different. You'll have three instructors. Me, All Might, and another faculty member will be keeping tabs on you," Mr. Aizawa said.

As the class gasped in surprise I clenched my fists under the table.

"Sir! What kind of training is this?!" Sero asked.

Mr. Aizawa held out a white card with big bold blue lettering reading 'Rescue'.

"Rescue. You'll be dealing with natural disasters, shipwrecks, stuff like that," he said.

"Disasters, huh? Sounds like we're in for a big workout," Kaminari said.

"Totally!" Ashido replied.

"Real hero stuff. This is what separates men from the boys. I'm shaking with excitement," Kirishima said.

"Finally I'll get to show off how good I am in water, ribbit," Tsu said.

"Guys I'm not finished yet," Mr. Aizawa said, glaring into the classroom.

Everyone quickly quieted down once they saw his stare.

"What you wear in this exercise is up to you. I know you're excited about costumes, but keep in mind you haven't gotten used to them yet and they might limit your abilities. This special training is at an off campus facility so we'll be taking a bus to get there. That's all, start getting ready," Mr. Aizawa said.

I grabbed my hero costume and quickly changed. Once getting outside, while waiting for the bus and others to finish changing I sat on the bench next to Shoto.

Shoto wrapped an arm around my shoulder and pulled me closer, letting my head rest on his shoulder.

"You can relax, I'll tell you when the bus gets here," he muttered.

I smiled at the sweet sentiment.

"I think I'm a bit too...excited now for that Sho," I replied.

"(L/N), come here for a minute!" Mr. Aizawa called.

"Yes sir!" I called.

I stood up and smiled at Sho before walking over to Mr. Aizawa.

"I didn't want to ask this in front of everyone, but what happened to your neck? It looks like someone choked you," Mr. Aizawa asked.

"Oh, well-" I began to reply when a loud whistle interrupted us.

We looked over to see Iida and I internally thanked him for the interruption.

"Gather round class 1-A! Using your student numbers form two neat lines so we can load the bus efficiently!" Iida ordered before blowing his whistle more.

Mr. Aizawa sighed before nodding at me to get on the bus.

As we got onto the bus Iida's face fell and we all just kind of filed in, sitting wherever we wanted due to the different layout of the bus.

"This open layout ruined my boarding strategy," Iida sighed.

I smiled a bit before looking out the window in my seat next to Katsuki, seeing as I'm the only one who he really stays calm around the class kind of shoved me into the seat before pushing him next to me. This, in turn, caused Jirou to sit next to Shoto.

'So what do I do? My real hope is getting to the center, but by the time anyone does arrive there Mr. Aizawa is already hurt. My hope really is that I stay up top with Iida's group so I could jump down and help. I'd get in trouble later, but hopefully Mr. Aizawa wouldn't get badly hurt,' I thought.

"It's Todoroki, Bakugou, and (L/N)," I heard Kirishima say.

Hearing my name I looked over in confusion. Katsuki looked at Kirishima before sighing and turning away.

"Sure but Bakugou is always angry so he'll never be that popular," Tsu said bluntly.

"What did you say?! I'll kick your ass!" Bakugou yelled, suddenly standing and grabbing the bar in front of us.

"You see?" Tsu asked.

"Katsuki, sit down," I said, pulling him to sit.

"You know we basically just met you, so it's kinda telling we all know your personality is flaming crap mixed with garbage," Kaminari said.

"You'll regret the day you applied to this school you loser! I'll kill you!" Katsuki yelled, standing up again.

"Katsuki," I hissed.

I struggled to keep him in his seat as he tried to walk over to Kaminari. Eventually the banter got out of control. I managed to get Katsuki to sit and I put my legs over his so we couldn't move. Katsuki suddenly got very quiet as he looked at me.

"What?" I asked.

"Get your legs off me!" he yelled.

"Are you gonna try and fight Kaminari?" I asked.

"Of course I am!" he yelled.

"Then no," I replied.

"Hey, hey! We're here, stop messing around," Mr. Aizawa called.

"Yes sir!" we replied.

Once we arrived I could feel my hands start shaking in fear. We all filed out and stood in front of Thirteen.

"Hello everyone! I've been waiting for you," she said.

"It's the Space Hero: Thirteen. The chivalrous pro who rescued a ton of people from disasters across the world," Izuku fanboyed.

"Whoo hoo! Thirteen is one of my favorite heroes!" Uraraka cheered.

"I can't wait to show you what's inside," Thirteen said, motioning into the door.

"This is gonna be awesome!" the class cheered.

As everyone began to walk inside I almost felt frozen in place. This is going to be terrifying and knowing Shigaraki is gonna be there.

He remembers me.

Yesterday still had me in a confused loop.

Why didn't he kill me?

Did he blame me for giving him false hope? In that case wouldn't he be angry at me? Instead he seemed kind of relieved or...happy to see me.

"(L/N), stop daydreaming and get inside," Mr. Aizawa said.

"Huh? Oh right," I replied.

I hurried inside after the class and I couldn't help but gasp in awe at the place. Sure it was filled with different disasters, but it was almost beautiful.

"Holy crap! It looks like some kind of amusement park!" Kirishima gasped.

"A shipwreck, a landslide, a fire, a wind storm, etcetera. I created this training facility to prepare you for different types of disasters! I call it the Unforeseen Simulation Joint, but you can call it USJ!" Thirteen called.

I could practically hear everyone thinking the same thing.

'Just like Universal Studios Japan.'

Mr. Aizawa and Thirteen began talking when I felt a hand grab mine. I looked over to see Katsuki as he turned his head away.

"Your shaking is annoying," he muttered.

"I'm just nervous," I replied.

"You'll do fine idiot," Katsuki said.

Thirteen went through her whole lesson, but I had my sights set on the fountain in the middle of USJ. The class cheered after her lesson and that's when I noticed the lights fade for a second and the fountain starts to go wild. I saw Kurogiri's portal open and Shigaraki looked through.

"Stay together and don't move! Thirteen protect the students!" Mr. Aizawa ordered.

"Whoa what is that thing?" Kirishima asked.

Villains began walking through and I quickly let go of Katsuki's hand.

"Wait, has the training started already? I thought we were rescuing people," Kirishima said.

Izuku moved to take a step forward when Mr. Aizwa yelled.

"Stay back!" Mr. Aizawa yelled.

He put on his goggles and I felt a chill run up my spine.

"This is real. Those are villains," Mr. Aizawa said.

That's when I saw the Nomu walk through the portal and Shigaraki looked up. I watched his eyes scan through the students before landing on me.

"The only real heroes I see are Thirteen and Eraserhead, perplexing. According to the schedule we retrieved from UA, All Might should be here as well," Kurogiri said, his voice resonating through the building.

"So you scumbags used the press as a cover and sneaked onto campus," Mr. Aizawa replied.

"Where is he? I went through the trouble of bringing so many friends who are eager to meet him. They want All Might, the great Symbol of Peace. I can't believe he's not here. Maybe if I kill a few kids he'll come out to play," Shigaraki said.

Mr. Aizawa's scarf and hair floated as the villains walked closer.

"What?! Real villains? No way. How could so many of them get into a UA facility that's secure?" Kirishima asked.

"Yeah, Thirteen, why aren't the alarms going off?" Yaoyorozu asked.

"Good question, I'm not sure," Thirteen replied.

"Is the entire campus under attack? Or is this their only target? Either way if the alarm sensors aren't being triggered, then one of these villains must have a quirk that's masking their presence here. They carefully chose this isolated facility as an entry point at a time when a class was being taught. They're fools for trespassing here, but they've thought this out. Whatever their plan they must have a concrete objective in mind, but what is it?" Shoto asked.

"Thirteen get them out of here and alert the main campus. Actually if they've got the ability to block our sensors...then they might be jamming our regular communications too. Kaminari, try using your quirk to contact the school," Mr. Aizawa said.

"Yes sir," Kaminari replied.

"What are you gonna do? You can't fight them on your own! There's too many of them, even if you can nullify their quirks, your fighting style is not suited for this. Your quirk is best in stealth and one-on-one fights, that's not gonna help with a group," Izuku said.

"You can't be a pro if you only have one trick. I'll leave it to you Thirteen," Mr. Aizawa said.

He jumped down the stairs and quickly took care of three villains. Before attacking more by himself.

"Whoa, he's holding them off. I guess I shouldn't have underestimated him," Izuku muttered.

"This is no time to be analyzing, we have to go!" Iida called.

Izuku looked over to me and grabbed my hand before pulling me along.

"He'll be alright," he said.

We ran towards the exit when Kurogiri appeared in front of us.

"There is no escape for you. It's a pleasure to meet you. We are the League of Villains. I know it's impolite, but we decided to invite ourselves into this haven of justice to say hello. And besides, isn't this a fitting place for All Might, the Symbol of Peace, to take his last breath. I believe he was supposed to be here today and yet I see no sign of him. There must've been some sort of change in plans we could not have foreseen. Ah, well, in the end I suppose it doesn't matter, I still have a role to play," Kurogiri said.

Before Thirteen could use her quirk, Katsuki and Kirishima moved in to attack.

"Did you think we were gonna stand around and let you tear this place to shreds?" Kirishima asked.

However when the smoke from Katsuki's blast disappeared Kurogiri was still standing.

"You stand up to your school's reputation, but you should be more careful, children, otherwise someone might get hurt," Kurogiri said.

"You two, get out of the way right now!" Thirteen ordered.

"I'll scatter you across this facility to meet my comrades and your death!" Kurogiri said.

He covered all of us and I suddenly felt the floor disappear underneath me. I fell through Kurogiri's portal soon enough I found myself falling through the air. I quickly created a platform under my feet and slowed my descent until I landed on the ground. My eyes scanned around the area when I saw the fountain.

I'm in the center of USJ.

I felt a presence behind me and I quickly ducked as a hand punched above me. I swung my leg around and tripped the man, but before I could knock him out another villain rushed over. I flipped backwards when my back hit someone else's back.

I looked over to see I was back to back with Mr. Aizawa.

At least this makes my goal easier, plus I'm getting to fight with my hot...ahem I mean skill teacher.

"(L/N)?" Mr. Aizawa asked.

Before any villain could take advantage of our distraction I created a bubble around us. The villains attacked, but their punches did little to my shield.


--------------------------------------------------------------------------------------------------------------------------------


"Everytime your light barrier is attacked by a strong blow it seems to become stronger in the next fight. However, once your shield is broken it causes damage to your body. If your shield is broken over and over in a short time period, the damage could cause fatal injuries. From what we can tell your bubble shield is permeable to air, but impermeable to everything else. That's the only information we can gather without doing extensive and possibly dangerous tests," my doctor explained.

After what my doctor had said I made sure to train with Katsuki and Shoto more. I mainly focused on my shields and bubbles to strengthen them for future attacks.

I suppose it really did come in handy.

Didn't it?


--------------------------------------------------------------------------------------------------------------------------------


"That portal villain separated all of us, I'm pretty sure everyone scattered throughout USJ," I explained.

Suddenly I felt discomfort in my abdomen and my face scrunched in response. I looked over to see a large crack in my shield with a villain seemingly reloading their canon-shaped arm. Mr. Aizawa's eyes snapped over and the man's quirk stopped working.

"Stay close," Mr. Aizawa ordered.

Oh always, handsome.

Ugh, focus!

Fighting the minor villains was surprisingly simple. Though, it wasn't by any means easy as there were so many of them. I created a whip made from light and would use it to restrain the enemy while Mr. Aizawa would render them unconscious. Mr. Aizawa knocked out another villain as Shigaraki ran towards us.

"Final boss," Mr. Aizawa muttered.

Before I could stop him he rushed towards Shigaraki. Before Mr. Aizawa could finish his attack. I shot out my whip and made it wrap around his waist. I pulled on my whip making him fly back towards me.

"(L/N), what the-?!" Mr. Aizawa began.

"Don't let him touch you!" I yelled.

Shigaraki kept moving closer and I used my hold on Mr. Aizawa sent him further away from Shigaraki. I turned just in time to create a shield between me and Shigaraki.

"(L/N)!" Mr. Aizawa called.

"Ah so that's your name. I'm sure I saw that somewhere in those files. Wasn't it...(Y/N) (L/N)? Daughter of Doctor (L/N), the famous hero doctor. You have a mix of your parents' quirks, light manipulation and healing," he said.

A chill ran through my body as his ruby eyes met mine and his mouth curled up into a disturbing smile. He kept trying to break my shield which I dropped right before it broke. I kicked Shigaraki away before feeling something wrap around my waist. I looked down to see Mr. Aizawa's scarf. He pulled me backwards and behind him.

"That annoying quirk of yours isn't suited for drawn out fights against big groups, is it? Don't you think you're a little out of your element here, Eraserhead. You're much better at working stealthily. You're known for surprise attacks, not fighting head-to-head, but despite knowing that you didn't hesitate to jump into the middle of this fight to put your students at ease," Shigaraki rambled.

As Mr. Aizawa focused on Shigaraki. I moved to his side and blocked an attack from a villain with metal claw hands. As he moved to attack again I quickly wrapped my whip of light around him and pulled him to block an attack from another villain with a ball-and-chain weapon. Mr. Aizawa then knocked out the second villain as I roundhouse kicked the third.

"And look at you, you're still standing. You really are so cool. Oh, by the way, hero. I am not the final boss," Shigaraki said.

That's when I noticed the looming figure of the Nomu behind us.

He was so fast I didn't even notice him move behind us!

I created a barrier blocking the Nomu as he reached forward. When his hand touched the barrier I noticed how big he truly was. He was a little over a foot taller than I was and was far more muscular. His fist reared back for an attack. I felt a surge of fear fill my body.

My body moved before I could think. I kicked Mr. Aizawa away from the Nomu and I.

Damn...I just kicked Mr. Aizawa.

Life seriously fucking sucks at the current moment.

Hopefully he doesn't hold it against me.

A sharp pain appeared in my abdomen as the Nomu destroyed my barrier with one bunch.

It felt like life slowed down for a moment as I felt my body falling over. The taste of blood soon followed as my body hit the ground.

This hurt far worse than the time Katsuki broke my shield.

It felt like I was dying.


--------------------------------------------------------------------------------------------------------------------------------


Aizawa: (L/N), (Y/N) how dare you throw me around!

*Shigaraki will remember this*

Aizawa: *Proceeds to pull and push (Y/N) throughout the battle*

(Y/N): Fine...I'll kick you around instead.

I'm so sorry for the late post! However I wanted to make sure this chapter was actually good before posting it, and I felt like rewriting it due to me feeling unsatisfied with the former results.

Also, a little more information on your quirk. Also, let me explain a little bit about how more of your quirk's information will come out.

I will either give more explanation during battles, whether they're training battles or actual villain battles, or after the battle.

I just find it easier to explain how your quirk works in a specific scenario when that scenario is happening or directly after. That way it's not just thrown in randomly.

ANYWAY!!

Tell me what you think about this chapter, I always love hearing what you all think.

Till next time: stay safe, don't forget to take care of yourself, and have an amazing day/night! 🤍
