In Class 1-A Dorms

"We've got regular classes starting tomorrow, huh?" Kyoka asked, letting out a yawn.

"There is no rest for heroes." Momo stated.

"They could have just give us one break though..." Y/N sighed, looking at her egg, noticing it moved a bit.

"But man, a lot sure has happened!" Rikido sighed.

"I will never forget this summer for the rest of my life." Fumikage added.

"Yeah..." Y/N sighed.

"Has your egg hatched yet? I'm so eager to see what she look like." Ochaco asked, leaning over.

"Not yet, but it has been moving lately. It's going to hatch soon. Hopefully, not too early."

"I bet that dinosaur will look awesome." Denki grinned.

"I hope it's not that scary..." Mineta whimpered.

"Or is it?" Y/N teasingly smirked, making Mineta shiver.

"Hey, go out front later."

Y/N heard Katsuki's voice and slowly turned to see him with a rather calm expression as he walked past Izuku.

"Let's have a talk about your Quirk."

Izuku's and Y/N's eyes widen.

"Kac... chan..."

Y/N narrowed her eyes in suspiciousness if he knows about Izuku's Quirk. She glanced at her egg to the window and sighed. Knowing that tonight, she's going to find out what Katsuki and Izuku are up to now. She knows it's going to be more than just a 'talk'.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

That night, Y/N was just sleeping in her room with the egg that's cuddled up safe and sound right to her by the nightstand when she heard the sudden loud explosion. Y/N jolted up awake and got out of the bed. She looked back at the egg to see it okay and opened up the sliding glass door and went over to the balcony to see explosions and fire in the Ground Beta. She stand correctly that Katsuki and Izuku are fighting. Without a second thought, she jumped off the balcony and landed on her feet.

"Young L/N...?"

Y/N turned to see All Might. Looks like he heard it too.

"I need to stop them. Please."

All Might nodded.

"Go. You have my permission."

Y/N then started running off in speed. Once she made it, she could hear a very much clear loud explosion with loud voices from the two boys. Stealthy as she could be, she hid behind the wall and looked over at the boys as they gave each other a blow.

"Why...?!"

Izuku swiftly kicked him away, causing Katsuki to fall on his butt.

"A-Are you okay?" Izuku questioned about to reach out to him when Katsuki slapped his hand away.

"Don't worry about me! Fight! What the hell's wrong with you?"

Katsuki stands up, stumbling backwards.

"Why... Why did I end up having to chase after the backs of someone who was always behind me? Why did a damn small fry lik you get strong... and become acknowledged by All Might...? Why is it you become strong... but I..."

Y/N frowned to see him like this as his voice waver.

"Why was I..."

Katsuki looked up with a frustrated and upset look on his face, gripping onto his black tank top.

"Why was I the one who ended All Might?!"

"Katsuki..."

"If I'd been stronger and if I hadn't been kidnapped by villains and saved Y/N then that wouldn't have happened... All Might tried to keep it a secret... I couldn't tell anyone! Even if I try not to think about it... it just comes to mind unexpectedly! I don't know what to do!"

Y/N couldn't help but grip onto her shirt where her heart is. It hurts her to see her friend suffer like this as well as her memories as they're all coming back to her.

~FLASHBACK~

She doesn't know how long she had been inside the van until she heard voices that are unknown. The door open and she backed away in fear and saw a man in white coat.

"Hey there, kid. Are you doing okay?"

"...."

"Don't worry I won't hurt you. I'm Dr. Wu. I'm here to take care of you."

Tell that with that fake genuine smile on his face. Y/N though was oblivious and slowly crawled out of the van. Dr. Wu slowly took her hand and brought her on the way to his lab. She found herself in the white area with glass tubes, bottles, sink, supplies, computers, and a glass box full of reptiles, even eggs.

"Welcome to my lab, Miss Y/N."

"H-How do you k-know my name...? W-Why am I here? I wanna go home..." she whimpered.

"Well, sweetie, I know a lot about your parents. I know everything. And you're already home."

"But I don't like it here..."

"You'll get used to it. Now, come and sit here." he gestured to her in the chair with straps on it.

Y/N was confused and did what she was told and sat down. Dr. Wu then strapped her arms and legs, making sure she wouldn't move. Now, she was scared as she tried to move.

"Don't be afraid. I just need your blood for a test." he took out the syringe.

"N-No... Not the pointy thing. I hate those!"

"Don't worry. Just one injection and we're done."

Y/N kept on struggling and yelped to feel a sharp object into her skin. She cried and watched as the red was shown inside the syringe until it was half and he pulled it out of her. But that doesn't stop her from crying. Dr. Wu wiped out blood on her arm and placed a small bandage on it and left her there as he checked out the blood in the syringe.

"Take her to the room. She would need some rest for now." he ordered.

The soldier from earlier took her out of the strapped chair and harshly took her to a small bedroom with a small window where she can't get out.

"Get some rest, you little brat."

They pushed her inside and locked the door on her, leaving her vulnerable and crawling onto the bed and curled herself into a ball. She feels like there's nowhere else for her to go and has no one. No mom and dad, no relative, no friends, no cousins, no one else for her to live with or be safe around with. Years went by as she was being tested, forced to do a rather harsh training like hand to hand combat, and more horrible things in her childhood days. She would always be punished if she never do what they say or listen or make mistakes. Dr. Wu would always tell her whenever she made a mistake in her training as the boss soldier whacked her in the face with a hard staff.

"Any mistake is certain death and death is your failure."

The big muscle man stood before her. He growled and grabbed her in the air and threw her towards the wall. Her back was slammed hard and she gasped out in pain. Little Y/N turned and saw some ray of light next to her with the small hole that fits her perfectly. She looks back to see the big man searching for her as he yells. She quickly pushes herself inside and moves over and looks through a hole. What she saw made her smile. There stood a beautiful sun with birds flying, and a river with trees and valleys.

"Hey!!"

Y/N gasped and turned to see the angry boss soldier looking straight at her eyes.

"What are you doing here?! Get back here!!"

She looks back at the outside hole with a sad look and walks back. She's ready to take a blow from him when Dr. Wu calms him down.

"Relax. I see you admire its beauty from the outside world, didn't you? That's nice. But with those so called 'heroes' out there leading a wake of devastation wherever they go. That's why, Y/N, you must stay focus. Never relent. Always attack."

"But I never want to hurt anyone..! I don't wanna be a monster like those scary guys keep on telling me..!"

"Monster is a relative term to a canary. A cat is a monster. We're just used to being the cat."

Dr. Wu nodded to the boss soldier. He grabbed her and threw her over.

"Teach this one a lesson!!" the boss soldier ordered.

The big muscle man stomped over to her, grabbed her in the air, and started punching her relentlessly as the men watched.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Y/N who's 15 years old was right now jumping over the tallest pillar without stopping as she kept on jumping. Just as she was getting a hang of this, she accidentally slipped and fell off. Luckily, she grabbed onto the edge to stop herself from falling. Shadow stood over her and she looked up to see Dr. Wu. He brought out a staff and slammed it against her hand, making her grunt.

"Are you weak?"

Y/N's face started to sweat as she gritted her teeth in pain. Dr. Wu twisted the staff, giving her more pain, hearing some cracks.

"Are you weak?"

Y/N didn't say anything as she tried to hold in her pain. He angrily twisted her hand again but harder with the staff hearing more crack.

"ARE YOU WEAK?!!"

"GAAAAAAAHHHH!!!!"

Y/N flipped over the doctor and landed and jumped over to the next pillar, continuing her training. The doctor smiled wickedly.

"Yes... The fire stirs inside of you."

Y/N made to her next training where everything is dark. She couldn't see a thing.

"To defeat the one, your senses must be sharp."

With those word, the firey arrow shot straight towards her and she quickly jumped back. Y/N could see a better view of the arrow. She hear more coming her way and she moved to the side to avoid them while jumping and dodging. Dr. Wu could see her getting stronger and more smarter.

"Her time is almost at hand. Once she suceed, she will be our superweapon for us to take over the world."

Y/N though heard it and scoffed. She will never be their weapon and rather die. Another day has come as Y/N ran over to the tallest building where as the soldiers got ready to shoot her. This is part of her last training. Y/N turned into the Indoraptor and started climbing. She dodged the bullets that are shooting her and pounced towards the soldier and stabbed him in the chest with her claws, making him fall off the building. Y/N slaughtered all the soldiers that are in her way as well as biting them off as blood poured out of her jaws. Y/N ran over to the last soldier as he threw arrows towards her. She dodged them all easily and stabbed him in the face as he's now dead. She ran up to the top until she finally made it to see Dr. Wu standing there with a proud look on his face.

"Your training is complete. Congratulations, Y/N."

That was then when Y/N was suddenly about to get sold by the rich people without letting Dr. Wu process what's going on or stop them because he needed her. Well, that's a good thing and they have every right to take her away from that crazy doctor. And that's how it all started.

~FLASHBACK END~

Y/N snapped out of it to hear another explosion again. She turned to see them started fighting again. Y/N knew that this has to stop and ran over to the boys. As Izuku and Katsuki are about to give another blow, Y/N went between them and blocked each of their punches with both hands, taking the blow instead.

She could feel her hands being the only one in tremendous pain, but she didn't let it get to her and ignore it. The boys stood in shock to see her who's glaring daggers at them.

"ENOUGH!!"

Her right hand was burned from the Katsuki's explosion while her left was damaged and bruised from Izuku's punch as bits of blood are coming out.

"This has to stop. Katsuki, I know that you're guilty about All Might's retire. Trust I do. I feel the same. But it happens and it was his choice to do that."

Katsuki has a shadow casted over his eyes, staring at the burn mark while he listened. Izuku's eyes widen in fear and regret to see her hand badly damaged.

"You need to stop this stupid nonsense. I don't know what the heck is going on between you two, but I suggest we let go of that past and let's head back to the dorms."

"Y/N..." Izuku spoke. "This is something we have to do in order for me to get Kacchan to let ou his feelings."

"No. Enough is enough. You too, Katsuki." Y/N said, turning to Katsuki. "If you're going to tell me to fuck off, then you're gonna have to get through me first."

"Stay the fuck away, Lizard Freak. This isn't about you." he growled, glaring at her.

"No."

"I said stay the fuck out!!"

"No!! Like I said, you're gonna have to get through me first!"

Katsuki's red eyes narrowed and his teeth grinded together. Without hesitation, he threw a punch at her. She knew this was going to happen as she dodged it. She grabbed his wrist, twisting it, and made him turn so his back was facing her. Y/N hissed in pain from her hands, but still held on. Katsuki cried out in pain and grabbed her by the hair and threw her towards the fence. Her back was rammed hard.

She growled animalistically and got up, showing her eyes glowing red in anger. She caught on to see them going at it again. Y/N brought out her tail and bounced off the fence towards the boys. She slapped them in the head hard using her tail and wrapped her tail around them and pulled them down to the road. They collapsed and stumbed onto the ground.

"Like I said... you... can't stop me..." she panted.

"You... stubborn ass..." Katsuki groaned.

"Y/N... I have to settle this... with him..." Izuku groaned.

"I said... no... Enough..."

They laid there for a moment. Katsuki then sat up, looking all beaten up from his face and arms.

"...Deku got his Quirk from All Might."

"I know." she said.

Izuku's breath hitched.

"I didn't tell anyone. I kept it a secret as well since it's very personal."

Katsuki looked over at her hands.

"How's your hands?"

"It's fine."

"I'm sorry that I hurt you, Y/N..." Izuku frowned, slowly getting up along with Y/N.

"It's okay. Katsuki, everything isn't your fault. Like I said, it happens. Don't blame yourself for this. That will get into your way of becoming a hero."

Katsuki's eyes soften.

"Y/N..."

"What is going on here?"

They jumped and turned to see All Might.

"All..."

"...Might..."

"I'm sorry I didn't notice..." All Might apologized.

Katsuki stood up and looked away.

"It's too late... Why Deku...? It started when the sludge villain came, right? Why this guy...?"

Y/N stayed silent.

"He was powerless, but more heroic than anyone else. I thought you were strong. You were someone who could already compete. I decided that he should also be able to stand in the ring."

Katsuki gritted his teeth.

"I'm weak, too, you know...! I always wanted to be strong, like you! It's because I'm weak... that I made you turn into that...!"

All Might stood close to Katsuki.

"This isn't your fault, like Young L/N said. Either way, my limit was close. I was always going to end up like this. You're strong. But I focused too much on your strength. I ended up making you bear that burden..."

All Might pulled Katsuki in a hug.

"I'm sorry, even though you're still young, too..."

Katsuki pushed himself out from All Might.

"After being a hero for a long time, I've seen that being fixated on victory like you, Young Bakugo and wanting to save those in trouble like you, Young Midoriya... If either of those feelings is missing, then a hero won't be able to carry out the justice he wants to carry out. Like how you, Young Midoriya, admired Young Bakugo's strength, and how you, Young Bakugo, feared Young Midoriya's heart... Now that your feelings are out in the open, I think you both understand. If you both recognize each other and can focus on making each other stronger, then you can save people to win and win to save people, becoming the greatest heroes."

Katsuki and Izuku lifted their heads and looked at each other.

"That's not... what I wanted to hear..."

Katsuki sat down and placed his elbows on his knees, hanging his head down.

"You... had the strongest guy lay the groundwork for you. Don't lose."

"I'll get stronger, so I can beat you." Izuku declared.

Y/N softly smiled at the scene before her. All Might turned to Y/N.

"Good job trying to stop them. Are you hurt?"

"A little. But I'm fine. It's just my hands that's injured. No biggie."

Katsuki sighed, lifting his head up.

"Who knows about you and Deku besides me and Y/N?"

"Recovery Girl adn the principal..." All Might confessed. "Of the students, it's just you two."

"You don't want this to get out, do you, All Might? Since it sounds like you're trying to hide this, I won't tell anyone. I won't expose your secret like damn Deku here. I'll keep it between us."

"As do I. I won't tell anyone either. It's very personal." Y/N nodded.

"Kacchan... Y/N..." Izuku mumbled, looking at them.

"I should be bowing and begging you to keep this secret. Just how much will I need you to be considerate for my sake...? Sorry, thanks." All Might said.

"I'm not being considerate. It's just too big a risk with too many drawbacks to spread this around." Katsuki said, standing up.

"Now that it's come to this, I must explain enough to satisfy you, as well, Young Bakugo, Young L/N. That is only reasonable."

All Might told Katsuki and Y/N about the power passed down from one generation to the next to stand against a great evil. How he became the number one hero and Symbol of Peace with that power. How he was gravely injured and neared his limit. And how he selected his successor. Y/N couldn't utter a word at what she was hearing and was in shock.

"Basically, if this is exposed, there'd be confusion about where the power is and stuff, huh? Jeez, damn Deku, why'd you have to go and tell me for?"

Izuku gulped, looking down.

"My using up all the power was my own choice. Like what L/N said earlier, but it was not your fault." All Might said.

"In the end..." Katsuki spoke. "...it doesn't change what I have to do."

"Yeah, you're right."

"But unlike what I've been doing until now, Deku-- Like how you've been watching me and I'll also make everything my own to go higher. Higher than even you, the chosen one."

Katsuki looked at Y/N.

"Don't think I forget about you, Y/N. You better not hold back. I will beat you again and win this time."

Her eyes widen in shock before smirking.

"We'll see who's the best in the future."

Izuku was surprised at first before it turned into confidence and put his fists up.

"Th... Then, I'll go even higher than that!"

"Huh?" Katsuki questioned.

"I have to get higher than you!"

Now that made Katsuki pissed off, causing Y/N to snicker.

"I said, I'm gonna surpass you!"

"And I'm saying that I need to go higher than that!" Izuku yelled back.

"What?!"

Y/N sighed, shaking her at the two bickering, idiot boys. She went between them again and knocked them over. They stumble for a bit and quickly got back up.

"Less arguing, more walking."

"Hey!" Katsuki growled. "You damn, Lizard Freak!"

"Who are you calling, Lizard Freak?!" Y/N snapped, turning to him.

"If the shoe fits!"

"...Say that again..."

"If.The.Shoe.Fits." Katsuki smirked.

"Okay, Katsuki Bakugo..." Y/N smirked, cracking her knuckles.

"K-Kacchan! Y-Y/N! Don't!" Izuku stammered.

But it was too late as Y/N charged him and headlocked Katsuki. Katsuki headlocked back at her as they walk along the way with All Might leading them back to the dorms. Izuku tried to pull them away, but they were too strong as they yell at each other. The secret Izuku had with All Might became a secret four of them shared.
