((Y/n)'s age: 10)

"Dad I wanna be. a hero when I grow up!" (Y/n) exclaimed and Mamoru growled in agreement.

"That's great! You'll be the best hero ever and with Mamoru as your companion you can do anything!" Daisuke exclaimed as he picked her up.

"Now we have to find a gift for Mom!" (Y/n) giggled as her father got distracted by a loud boom heard from the street.

"Eh we can do that later," Daisuke picked the girl up and started walking a bit further," There's a villain attack right now, so let's be careful. Okay?"

"I'll be careful, besides I have Mamoru so you should be the careful one," (Y/n) said as she tried to look over the man's shoulder.

"(Y/n) I'm going to leave you here. I'm going to see if any civilians got captured," Daisuke set her down," Mamoru protect her."

Mamoru nodded and bit onto (Y/n)'s shirt to prevent her from running to her father. Daisuke started jogging towards the crime scene, he was a cop so it was his job to keep the civilians protected.

"Let's go Mamo-Chan!" (Y/n) exclaimed as she broke free from the wolf's grip," We gotta see Dad in action!"

The two of them ran to the scene, slowing down once (Y/n) stared around them. The buildings were collapsing around them, blood was everywhere, people were pushing against the two of them while they were trying to escape. In the middle of the chaos stood Daisuke, All Might, and the villain. The villain had Daisuke captured and had his hand gripped to his throat.

"Dad..." (Y/n) breathed out at the sight, tears filling her eyes," DAD!" She started sprinting towards the scene," DAD YOU'LL BE OKAY!"

All Might panicked, his time limit was running out.

"YOUNG CITIZEN STAY BACK," He yelled at the girl as she rushed towards the scene," DON'T WORRY FOR I AM HERE!"

"(Y/n) stay back," Daisuke rushed out.

"SHUT UP BOTH OF YOU," The villain growled and tightened his grip on the Father," The damned cops and heroes didn't have to get involved into this." His hands glowed and transported (Y/n) towards him, switching her for her father.

"Now you either let me go or the girl dies," The villain said, squeezing he girls neck.

(Y/n) screamed out in pain and her father winced.

"All Might you have to save her!" Daisuke cried out.

"VILLAIN LET HER GO!" All Might rushed towards the villain and tried to punch him, but he jumped out of the way with (Y/n).

"LET MY DAUGHTER GO!" Daisuke screamed at the villain," MAMORU ATTACK THE VILLAIN!"

Mamoru sprinted towards the villain, teeth out and ready to bite the villain.

"Damned mutt," The villain's eyes glowed and Mamoru stood still for a few seconds," Attack All Might!"

Mamoru turned and started sprinting towards the Pro Hero.

"MAMO STOP!" (Y/n) screamed out as her companion was about to tear into All Might.

In a blink of her eyes Daisuke sprinted out in-front of All Might, getting pushed to the ground by the gigantic wolf. Mamoru's claws pierced into the man's chest.

(Y/n) froze as she saw the scene lay out in-front of her eyes.

The rest of the fight was a blur to her, and eventually the villain was captured when Eraserhead came to the scene and erased the man's quirk, letting All Might capture him and Mamoru turn back to normal.

"Dad..." (Y/n) muttered as she furiously wiped tears away and ran up to All Might in anger," You're no hero. You let my dad die. Before I could even grow up you let him die just because you couldn't save yourself from a stupid mutt."

"Young child," All Might started but suddenly froze,' My time limit is up.'

"I'll take it from here," Eraserhead cut in, letting All Might escape.

"What's your name and what happened," Eraserhead asked the normal questions.

"I- I want to go to my mom," (Y/n) cried out.

~~

"Mamoru you stupid mutt," (Y/n) cried out, unintentionally hurting the wolf's feelings," You killed my dad."

The big wolf whimpered and tried to get near the girl but stopped as she back away in fear.

"I hate you," (Y/n) cried out," If I didn't have this stupid quirk you wouldn't be here, and if you weren't there, you-you wouldn't have killed my dad and All Might could've saved us all."

"(Y/n) its time for the funeral," Kitagawa knocked before slowly entering the young girl's dark room," You cant keep yourself in here forever. Shoji has been asking about you."

"If  I go out again Mamoru will hurt someone and kill someone," (Y/n) whimpered," I try to keep summoning other animals but only Mamoru will appear."

"(Y/n) it wasn't his fault," Kitagawa looked at the wolf who had only been strong and now was weak," Somebody forced him to do that, Mamoru would never hurt somebody that you loved."

"But it still happened, it-it was my fault wasn't it? I should've just stayed where dad told me," (Y/n) cried out and clutched onto her mother, soaking the woman's  shirt with tears,"  Dad was supposed to stay alive. He promised he would  watch me become a pro hero."

~~

"(Y/n)? Where's  Mamoru?" Shoji asked as the girl came to school without her wolf companion besides her," He's always with you!"

"I don't know, I kinda like the cuter animals now. Mamoru is more scary. He's not an animal a hero would use," (Y/n) lied through her teeth while she held a small bunny in her arms.

"Really? If you ever become a hero I think Mamoru would be an amazing hero with you, he's badass looking and scary at the same time," Shoji said.

(Y/n) glared at him with a tick mark on her forehead," Stop using bad words Shoji! Your mom will be disappointed when I tell her!"

"SORRY! PLEASE DON'T TELL HER!"

~~

"You left that day, instead of staying. You left a ten year old girl on a crime scene," (Y/n) yelled out, staring at the ground," You left instead of comforting someone who saw their dad die because of their quirk, I couldn't even summon Mamoru back for years because I would get reminded of that day. I would remember Mamoru's face soaked in blood, you doing nothing as he clawed into my fathers chest, I was left with fucking Eraserhead. He couldn't even comfort me, I was shocked and he was asking questions about that. It's not fair, you shouldn't become a fucking hero if you can't save the people who are living. I was a child, no child should have to experience that."

"Young (Y/n)-" All Might was cut off by (Y/n).

"I hate you. You were never a hero to me, you were just a villain who abandons people," She spat at him," You have no damn excuse for you leaving. Leave now."

All Might nodded and slowly walked away from the angered girl. (Y/n) leaned against the wall and slid down to a sitting position.

"I finally told him," She said to nobody.

"(Y/n)?" Kirishima exclaimed as he saw her," Your opponent was found out for cheating. She had a group of people, one would erase your quirk and the other one had the quirk to shock people. She also brought in gadgets that she hadn't filled forms out for. You would be able to fight, but since you were unconscious you were eliminated but before she was eliminated she fought Bakugo and he beat her up, badly."

(Y/n) looked up at the spikey haired boy, a smile on her face as always," Really? Oh my gosh I knew she was cheating from the start! Ugh I wish I could've competed but I know I would've lost against Bakugo."

"I mean you did fight long and hard," Kirishima helped her stand up," You were beaten to a pulp though. You sure you're okay?"

"Physically I'm okay! Recovery Girl fixed me right up," She said.

"And mentally? Are you okay?" Kirishima asked before they entered the space where their class was seated.

"Y-Yeah perfectly fine."

"You're not okay, are you?" Kirishima put his hand on her head and pulled her into a hug. He felt her shake her head and his shirt become soaked by her tears.
