A lil' Erasermic and Kamishinso on the side.

I guess the Aizawa family has a thing for loud blondes. This is so bad but I really needed to post. Might come back and fix it later.

Y/n Shinsou. Twin sister of Shinsou Hitoshi, and most recognized of the two.

And boy was she a catch.

She had purple hair similar in color to her brothers, with a small (H/c) tint. She had (E/c) eyes with large purple eyebags beneath. She was constantly tired, and had a stoic face but was more friendly and outgoing once she was close. She was transferring into 1-a.

Reason being= her quirk.

Siren: She can control people by singing, rather than a verbal response. If they can hear the voice they are immediately under control. (during sports festival, everyone wore earplugs during her fights.)

The louder her voice the more control she has. She is also a HELLA GOOD SINGER.

She is also viewed as more of a villain despite her ranking and ancestry.

And today was her first day in class 1-a. She had transferred after the sports festival, coming in third (there are twenty one places in 1-a, you replaced some weird transfer idk).

She followed her...

teacher...

through the door staying quiet as to not attract any unwanted attention.

"Alright shut it and listen." Aizawa demanded, cutting off the chatter.

"As you know, Lyrale was transferred into general studies, this is the student replacing her. Meet y/n Shinsou. Treat her with respect, or I'll expel you." The teacher hissed, sighed, and pointed her towards her seat. She smiled and sat down, watching as the teacher rolled his eyes giving the kids a period to visit since he was 'tired'.

In all honesty she was too. She watched with a giggle as he pulled out a large yellow sleeping bag and slumped to the floor.

'Man those night patrols must be hard.'

She pulled out a small sketchbook opening it up, only to be swarmed by people. She recoiled into her seat, trying to push everyone away before her anxiety got the best of her.

"Oi, shitheads, back the fuck off, she's clearly uncomfortable."

She smiled to herself when most everyone backed up and left, leaving a rather angry looking blonde, and pink haired and skinned girl with horns, a redheaded boy with a large smile, a taller black haired boy, another blonde with a lightning bolt in his hair, an unruly haired boy with freckles, and a rather stoic looking boy with two toned hair.

"Look, shithead, these guys are going to ask you a hell of a lot of questions. Have fun." The blonde finished sarcastically, revealing himself as the savior she had been thankful for earlier.

"U-Uh, h-hi, I-I'm Izuku M-Midoriya!"

"I'm Mina Ashido!"

"I'm Kirishima Eijiro!"

"Kamanari Denki!"

"Sero Hanta, and that's Bakugou."

"I am Shoto Todoroki."

She gave a small bow and wave from her seat.

" W-we're here to ask questions."

"First of all, are you Aizawa's secret love child."

'Ah so this is the one D-Mr. Aizawa warned about.'

"No, sorry. But I am Hitoshi Shinsou's twin sister if that means anything."

Midoriya wrote down a few things in his notebook, before asking multiple questions related to her quirk and such.

'Today is going to be a long day.'

The girl sat with a huff next to her brother as she set down her food.

"Tough day?" He asked with a smirk.

"Jesus, it's like those kids have enough energy that would last me the rest of my life!" She responded, pushing away her plate.

"You want some of my food, Dad forgot to pack me a lunch so I had to buy some." He asked.

"I'm good, I'm not really hungry." She responded his quirk having no effect on her.

"You sure?"

She opened her mouth to respond when a certain group of energetic teens filled the spaces around them. The Bakusquad.

"Here we go..." She whispered folding her arms across her chest as she leaned back.

Kamanari went off into a small rant about how he didn't know the two were related and had such similar quirks. Hitoshi smiled at the boy, opting to get his number.

Her eyes drooped as she zoned out, staring down at the food she had rejected so easily.

"-/n. Y/n!" She snapped back to reality as her brother snapped his fingers in front of her face.

"Sorry, must've... zoned out." She apologized, getting a few weird looks from her classmates.

Hitoshi gave a small worried glance as Kirishima continued with the question he had. She gave an answer letting him continue, ignoring the worried stare of a certain explosive boy.

She weakly ran along the sidewalk to catch up with her brother as they walked down the hill towards their home.

She pulled out her key unlocking the door as they threw their bags onto the couch searching through the cabinet for snacks.

Y/n pulled out a granola bar as her brother grabbed a bag of chips. They parted ways, and she watched as her brother eagerly texted his 'new friend'.

"If you don't do the laundry I'm telling Dad about Kamanari." She teasingly yelled down the hallway at him.

He scoffed, turning around and making his way to the laundry room.

"I hate that you can use that against me."

"Well Dad did say no loud blondes."

"Yeah well Dad is a hypocrite so,"

She laughed entering her own room and closing the door.

She pulled out her homework, begrudgingly doing the work she had been assigned.

She yawned as she scribbled down the answer to a question.

Her eyes drooped as her body slowly leaned to rest against the desk.

Her brother knocked on her door, laundry in hand.

He entered even though no response was heard, and smiled at the sight before him.

"What are we going to do with you?" He whispered picking her up and setting her down on the bed.

She curled into the blankets basking in their warmth.

He playfully rolled his eyes walking away to make dinner.

She yawned trudging into the kitchen and sitting down at the table with a loud thud.

"So how was your first day~" Her father teased eating his dinner quickly so he could start his radio show.

"Fine, I'm just tired."

"You're not even our actual kid and you guys take after us so much." Her Dad mumbled under his breath earning a laugh from his husband.

"Yeah, Yeah whatever." She chuckled. Her father stood up grabbing his headphones and giving a small wave.

"How much you wanna bet he's not going to get any sleep tonight?"

"Hitoshi!"

"What? It's true!"

"He's not wrong."

"Not you too Dad!"

"Two against one. I bet five bucks and you have to do the laundry tomorrow."

"Fine."

"You realize she's going to give him hot cocoa in the middle of it right?"

"What?! We agreed that was cheating!"

"I didn't sign any papers."

"Ugh!"

"Darn, we don't have anymore milk..."

She mumbled moving things out of the way in the fridge.

"Hey Dad!"

He grumbled in response. looking up from his papers he was grading.

"I need to go to the store, we don't have anymore milk."

He nodded throwing his scarf at her.

"Use it if you need to. Be safe."

"Ok, Love you, bye!"

She grabbed her house key and a large coat, slipping into it as she pulled on her headphones. She jogged down the sidewalk with ease, quietly humming to the music. She fell into her own world as she slowed down in front of the store. She made her way in, silently taking in her surroundings.

Cashier-unthreatening, possibly flirty.

Mrs. Honasan- Family friend, most harmless thing on earth.

Man covered in tattoos with the motorcycle- possible threat, use caution.

Bakugou- Wait what?

She snapped out of her surveillance mode and turned towards the oblivious blonde.

"Oh, Hey, Bakugou!" She called out to him walking towards him. He turned remaining stoic.

"What dollface."

"Aw, dollface is a cuter nickname than Shitty hair or Deku!"

"What shit face." He corrected, annoyed with the bright ball of beauty before him.

"What! No go back!" She pleaded.

"Look I'm not doing this all night. What?" He demanded.

"Oh... Uh, I just wanted to say 'hi' since I saw you!" She spoke, slightly discouraged.

He shrugged turning back to the shelf as he surveyed the items.

"I recommend the leiahos, but the linntera brand is good enough and cheaper." She whispered offering sound advice. He grabbed one of her recommended ones and looked it over, deeming it good enough and put it in his basket.

"How the hell would you know? I'm told I'm the only one that can handle spicy shit." He asked raising a brow as they subconsciously walked together towards the milk.

"Oh, well, my family doesn't, but I do. I have to buy it myself though." She shrugged, pulling a milk down from the shelf.

They walked together around the store, making light conversation that Bakugou didn't know he could handle.

"And when he turned around, I punched him in the face because no one talks about my dad that way!"

He snorted at her small story as they walked out together.

"I swear, if it had been me, I would have thrown him into the wall."

She smiled laughing lightly.

"I wanted to, believe me, but if I had, my own father would have expelled me!"

He grinned continuing to listen to her talking. A small fire caught his eye, as he turned she gasped.

In front of them was the pro hero Endeavor standing over his passed out son.

She ran to her classmate's side checking if he had a pulse.

Endeavor scoffed as he reached to throw her aside.

A large explosion distracted him as the large pro turned to see an ash blonde.

"Don't touch her." Bakugou hissed, causing the pro hero to bashfully laugh.

Y/n snarled as her training kicked in.

"Bakugou cover your ears." She whispered. He nodded, reaching up to turn off his hearing aids.

She opened her mouth. Softly singing a small tune. The pro hero turned in annoyance before his eyes turned white.

She made a rather large hand gesture and he stomped off his brain unable to process his movements.

She nodded at Bakugou as he turned his hearing aids back on.

She helped lift their classmate onto Bakugou's back as she quickly led him back to her house. She unlocked the door leading them to the couch.

He set down Todoroki. Turning back to her as she rushed to get a cold washcloth.

Aizawa walked into the room sleepily not noticing two of his students also there.

"Y/n what's going on?"

He groggily asked lifting his head as he made eye contact with Bakugou.

"Dad, me and Bakugou were on our way back from the store and we saw Endeavor and Todoroki! Todoroki was passed out so we brought him here!"

Aizawa tore his eyes away from the first boy as he saw the second boy unconscious on their couch.

Y/n looked up at her overly confused father as his eyes switched between both of the teen boys.

"No."

"What! Dad Todoroki is LITERALLY unconscious! What do you mean 'NO'?!"

Aizawa's brain clicked as he made his way past the very confused blonde as he made his way to the bi-colored boy.

"Call principle Nezu..."

Bakugou watched with furrowed brows and a silent tongue as the girl paced back and forth as the phone rang. She talked busily and quickly as she explained what she knew.

The three stood in silence as they watched the youngest Todoroki leave with their principle.

"Alright now I want to know why the hell you were talking with him."

Aizawa hissed at his daughter causing her to glare back with even more force.

"Because he was there and I was lonely. It wouldn't kill you to be accepting for once."

Aizawa grit his teeth sparing a glance at the clearly uncomfortable blonde.

"What did I say about loud blondes."

"You especially cannot say anything about loud blondes and you know it!"

Bakugou slowly inched his way to the door grabbing his basket as he tried to quietly open it.

A grey scarf wrapped around his wrist as the other Shinsou twin came down the stairs.

"Hitoshi, If you open your mouth I will literally tell dad all of your secrets."

The male twin froze as he weighed his options. He sighed walking into the kitchen and pulling out a small snack.

Aizawa opened his mouth to scold her once more before his husband came out of his radio room.

"Oh boy here we go..."
