QUIRK: Star shield

MENTION OF PANIC ATTACKS AND SELF HARM

Bakugou's eyes widened as he felt his chest tighten, the room just seemed too... loud

But then again, the ringing in his ears seemed louder, his pupils shrank as he stared at the floor beneath him, shaking furiously as his 'friends' gave him weird looks before running out into the hall to watch the fight.

He could feel what seemed like water flowing from his eyes, but his head was down so it wasn't like anyone would see... or would they?

Y/n stood from her chair, glancing around the empty classroom before running over to Bakugou, kneeling down in front of him.

"Bakugou? Are you okay?" She whispered, he tried to shake his head, but a sob slipped through his lips. the room was quiet now, the only sound, Bakugou's heavy breathing and sobs. Y/n took another look at the door, rolling her eyes as she saw through the window, that the teacher was not trying to stop the fight at all, clearly needing an excuse to get out of teaching.

"Bakugou, I'm going to touch you okay?" Bakugou only half nodded in response, not being able to see through the salt water coming from his eyes.

As Y/n's hand made contact with Bakugou's. She yelped as explosions erupted from her thigh and Bakugou was engulfed in a large shield trapping him. His eyes widened his breathing speeding up as Y/n was separated from him. She quickly ran over ignoring the explosions on her thigh, pounding on the thin material of the shield.

Bakugou recoiled into himself in the shield, trying not to pass out as his mind raced with thoughts.

Y/n finally, in a rushed moment of adrenaline, punched through the shield, her chest heaving, she continued opened a space big enough for Bakugou to crawl (more like be pulled) out of.

He fell to the floor on his knees, before being pulled into a hug by Y/n, her arms wrapping around his, still, shaking form.

He pressed his face into her shoulder, his breathing calming and his body allowing him to move once again.

"Did, did, did you really just trap me in a shield."

"No, Bakugou, No, I-, I don't know what happened, but my thigh started to explode, so there's that."

"Shit..." Y/n hummed questioningly, pulling away from the hug to look at Bakugou's eyes, it suddenly clicked for her as well, her eyes slowly trailing down to her skirt, she slightly lifted it, her arms pulling away from Bakugou.

She froze as the outline of an explosion appeared, then soon, color.

Bakugou almost started crying again.

"I'm so sorry." He whispered.

Y/n's eyes snapped back to Bakugou as the words slipped out of him, his eyes, finally meeting her own.

"I guess you're kind of stuck with a piece of shit for a soulmate."

"Yeah, well, I'm pretty sure that 'piece of shit' you speak of, is going to be the number 1 hero." Bakugou couldn't help but smile. He, in a way, was glad it was her, he had been taking more and more notice of her as she got closer to him, but he had still hurt her, and he regret it.

Bakugou glanced at her tattoo again, pausing as he saw a glimpse of a small red line, higher up her thigh.

'probably just a stretch mark.' (CUZ THEY'RE NORMAL AND COME WITH PUBERTY)

~*~*~*~*~

Bakugou sighed, slipping off his shirt and then his sweat pants, then his boxers to take a shower. He glanced down again, freezing as he saw a tattoo on his inner thigh.

"no." He whispered to himself, looking fully at the tattoo and internally yelling.

He immediately picked up his phone, pressing call on the number he had gotten earlier that day.

His bare foot tapped angrily on the floor of his bathroom, waiting for the number to pick up.

"Hello?" Y/n's voice echoed through the phone.

"THERE IS A BIG ASS (F/C) STAR LOOKING PEICE OF SHIT ON MY THIGH."

"Where on your thigh that it is so important to yell at me."

"MY INNER THIGH DUMBASS!" Bakugou was about to start yelling again before his mother cut in, yelling at him from the floor below.

"OI, KATSUKI, STOP YELLING AT WHOEVER THAT IS AND TAKE A DAMN SHOWER."

"OH SHUT UP OLD HAG!"

"Uh, I'm gonna go. Have a nice shower."

"Yeah Yeah, see you at school tomorrow."

"See you."

~*~*~*~*~

Bakugou watched with keen eyes as Y/n walked towards him, her uniform sleeves pulled low on her arms, covering her hands as well.

"Hey." She smiled, staring up at him.

"Hi." He responded simply, still staring at her arm.

"Uh, what's up?"

"Why are you hiding your arm."

"Oh, I burned it really badly when I was training the other day, and it kind of hurts when the air touches it, so I covered it, and I don't want people to make a big deal of the bandages."

Bakugou nodded, taking the excuse, but he was no idiot, he knew there was something she was hiding, he just refused to make a scene in the middle of the hallway.

~*~*~*~*~

Bakugou watched in confusion as a group of girls crowded around another. He couldn't tell who the girl was, but he knew she was being pushed around and hit.

He jogged over easily seeing over the crowd of shorter girls and his eyes landed on the girl in the middle.

"Look at her! She has those stupid cuts ALL over her~" One girl giggled, pushing Y/n further into the ground with her foot.

"Get off of me Aliane"

"Awe, is the shield girl going to protect herself?"

"No, but I will." Bakugou interjected, shoving through the girls and lifting Y/n to the ground.

"Cute-suki! Why are you helping her?" Aliane whined, reaching out to touch Bakugou's hand.

She huffed in annoyance as Bakugou pulled away.

"Look, stop messing with my soulmate."

"YOUR WHAT?!"

"We're so sorry!"

~*~*~*~*~

Bakugou and Y/n walked in silence towards Y/n's house, Bakugou's arm over her shoulder.

"What did those girls mean when they said you had cuts on you?"

"Oh, uh, nothing."

"Y/n."

The girl froze at Bakugou's stern voice. He had never truly used her first name until now. And she could tell it wasn't going to be pretty if she resisted.

"When we get to your house. You're going to take off your shirt and show me your arms."

"TAKE OFF MY SHIRT?!"

"Not like that!"

Bakugou rolled his eyes, his arm falling from her shoulders to her waist and he could tell she visibly flinched.

"You definitely have to now."

"Fine..."

As they made it to Y/n's front door she shakily reached for her key. Before she could react, Bakugou had taken the key from her, opened the door, greeted her (mother/father/guardian) and pulled her to her room.

As he closed the door, a few tears fell from Y/n's eyes, landing on the floor beneath her, her head hung low.

"Y/n... I know you're nervous, but I just want to know what's wrong."

Y/n nodded, slowly unbuttoning her school uniform to reveal a massive amount of various sized cuts on her torso and upper and lower arms.

Bakugou's eyes widened as he stepped closer.

"Is this... my fault?"

Y/n shook her head, but slightly nodded.

"It was mainly those girls but... I guess, you also, bullying me didn't help..."

Bakugou glanced up at Y/n's face for consent as he slowly ran a finger over one of the scabs.

"Promise me, you will NEVER. Do. This. Again."

"I need someone to keep me on track, but I can try."

~*~*~*~*~

"BAKUGOU! I GOT IN!" Y/n screamed as she ran down the street towards him, crashing into him in a hug.

"Me too teddy bear."

"Ooh, nice nickname!"

"Alright alright, now show me your arms."

Y/n happily pulled up her sleeves, showing him the scarred cuts, not fresh, but old, worn and nearly forgotten.

"I'm so proud of you..."

"Aww, babe!"
