Chapter Text




Shinsou hadn’t felt that ominous, yet oddly comforting, feeling in months. Not since his dad, yes he called Aizawa his dad now, had an argument with the teen known as Polaroid. 

The same teen that had saved him from his personal hell.

It was odd to miss the looming presence of a stalker-not-stalker. 

And yet here he was.

Shinsou heard of stories from his dad and pops about the little vigilante. 

Sometimes Polaroid passed messages along to him via his parents. 

Every time he got one of these messages his heart filled with warmth. 

They were always short little things.


“Glad to hear you’re doing well Shinsou!”


“Good luck on whatever you are doing! I’m so proud of you!”

He felt so warm and fuzzy at those messages.

And a little bit of something else he couldn’t really place so he just ignored it…

Shinsou often found himself thinking of Polaroid when left to his own thoughts. 

Why couldn’t he get this boy out of his head?

Shinsou tried not to think about him, but in doing so he only thought more about him.

It was a conundrum. 

He considered going to his dads, but he decided against that. This was something he could figure out on his own.

 Its not like thoughts could harm him… right?




Shinsou sighed as his brain decided that video games were boring and that he needed something to do. 

Luckily for him, dinner just finished and he was called to the table.

Aizawa grumbled a bit as he got up from the couch where he was dozing with the cats. Yamada laughed and shook his head fondly as he finished setting the table.

Shinsou strolled over to the table and slid smoothly into his seat.

The three said their thanks and dug into the good food.

They were half-way through the meal, chatting about training plans and the likes, when a gentle knock rang from the door.

All three of them froze and looked to the door.

A few more soft knocks.

Aizawa got up, his capture weapon ready, and crept to the door.

He peeked into the peep hole and reeled back in surprise.

“Polaroid?!” He exclaimed in surprise.

“Wait, Polaroid is here?” Shinsou asked a little hopefully as he got up from his seat.

“Why would the little listener be here?” Mic asked at the same time as him.

“I don’t know why he’s here. But I guess I should let him in.” Aizawa sighed, opening the door.

Sure enough, there was Polaroid in all his tiny glory.

He had grown a b it since Shinsou last saw him but he was still short.

In other words, he was tiny to Shinsou. Very tiny.

“Hey Eraser!” Came out Polaroid’s slightly distorted voice, “Just wanted to stop by! See how things are going ya know?” 

“No. I don’t know why you would do this when ma and my husband could very easily capture you.” Aizawa said in lieu of a greeting.

Polaroid laughed softly.

Oddly… it had a sad tone to it.

“But you wouldn’t Aizawa. You really wouldn’t.” Polaroid said.

“How would you know?” Aizawa countered, Polaroid laughed once more.

“You keep forgetting that I know a lot about you, old friend. But it’s not like you would know.” 

Aizawa tenses a bit at this but let Polaroid in.

Polaroid went as far as to take off his boots.

Shinsou didn’t know what he was expecting. But the long neon rainbow sock that Polaroid always wore having another pair of socks on top of them was unexpected. Especially since the socks were mismatching. One was white with black cats on them and the other was grey with lemons on it. 

And his feet were tiny.

“Hey Eraser? Do you have slippers or do socks work?” Polaroid suddenly asked as he looked up to Aizawa. 

“Just socks in this household problem child.” Aizawa sighed as he walked back to the table, “We were in the middle of having dinner Polaroid. What do you need?”

“Oh, I just wanted to check up on you and tell you some… important things.” Polaroid sounded serious, and what could be seen of his eyes told the same story.

A serious Polaroid was not someone to doubt or question.

“Alright, spill.” 

Like a flip was switched Polaroid was back to being all sunshine and rainbows. Aizawa pulled over a chair and Polaroid sat down on it.

“Alright, first off, how are you doing Shinsou?” Polaroid asked kindly, turning to Shinsou.

Shinsou jumped at the sudden attention but gave Polaroid a small smirk.

“Pretty good. Thanks to you. Dad and Pops have me in online school because they found out about the bullying problem, so it’s all-” Shinsou started but suddenly a dark aura came from Polaroid, putting everyone on edge.

“Who bullied you Shinsou?” Midoriya asked in a dark tone, his voice glitching so much it was menacing, “I want to know for a friend.” 

“Uh… Nezu already had a field day on the place and the people in it. So, no need to get so riled up dude.” Shinsou laughed awkwardly. 
Suddenly the dark aura was gone and everything was back to normal.  

“Oh. That’s too bad, I was kind of in the mood for some arson tonight.” Polaroid pouted playfully. Though it was hard to tell if he was kidding or not. “But I’m glad your doing better now. Your well being is far more important than revenge or arson.” 

Shinsou felt warmth spool in his chest and he smiled at Polaroid.

It wasn’t a smirk. It wasn’t sassy or playful.

It was genuine and soft.

“Thanks Polaroid.” Shinsou smiled.

Polaroid looked surprised for a second. 

The surprisingly tears gently fell from his eyes.

For the first time he took off his glasses.

Glittering green eyes, the same shade as his hair looked back at him. Tears gently fell down his face, but it was obvious he was smiling.

“Oh Shinsou… I have been waiting so long to see you happy. Truly, genuinely, happy.” Polaroid said breathlessly, “You are so strong. And I am very proud of you.” 

Shinsou felt his ears go red at the pure kindness (love) in the boy’s voice.

“I wouldn’t be here without you Polaroid. So… thanks.” Shinsou said, a little flustered.

Aizawa and Yamada were looking between the two with surprise and slight horror (mainly from Aizawa). Which they quickly schooled when the two boys looked to them. 

Polaroid put his glasses back on and sighed.

“Well, now that that is over, we need to talk more serious things.” Polaroid said, looking a little sad. “I’m going to be inactive for a while. I don’t know how long exactly, it could be weeks, or it could be months. But there is something very important I need to do. It will be dangerous, but I think I have it handled.”

The family of three frowned.

“You are fourteen, if my math is right, you shouldn’t be doing dangerous things. And I shiver thinking of what your definition of dangerous is if you don’t consider being a vigilante dangerous.” Aizawa said, “Can’t you get someone else to do it? You normally are good at getting help for the more dangerous things.”

Polaroid shook his head.

“No.” He sighed, “I have to do this alone. It’s… don’t tell anyone this, not even Tsukauchi. This does not leave the house. But it’s an infiltration mission. I won’t tell you of what, other than that they are very dangerous. I have been preparing fake identities, pasts, degrees, records, and everything for months now. And I have a lot of information on this group. I just need to get one person out and everything will be fine. That’s all. I just don’t know how long it will take.”

“I… you make a good point. But still… why does it have to be you? Why couldn’t I go in and do it? Or any other underground hero for that matter. You can just pass the information you have on them on and let that be that.” Aizawa argued. 

Polaroid lifted his glasses a bit to pinch the bridge of his nose. He rubbed a tired hand over his eyes and down his face.

Then he sighed and looked up at them with bone-tired eyes filled with deep exhaustion and sadness.

“Because the person I am saving is my daughter.” Polaroid answered.

The silence was resounding.

“You’re… you’re fourteen.” Yamada pointed out a little weakly.

“Yes, and she is four at the moment, five soon. And we are not related by blood. But she is still just as much my daughter. I have a son too you know.” Polaroid looked out a window sadly, staring into the darkening sky. “They both have been hurt so much. I managed to save my little boy. But he still hurts. And my daughter she… she is hurting… a lot. I couldn’t save her before now and I will always regret that. But I had to bide my time. I was too weak. But now… now I can save her. Just like I saved my other little one.”

He looked back at them with sad, but loving, eyes.

Any amount of the usual joking manner Polaroid was known for was gone and replaced with a wistful sadness.

“It has been so long since I have seen her. And I have to be the one to save her, to get her back. Some day you will be able to meet her. And my son. They both would love to see you guys.”

Polaroid got up and walked to the door and started pulling his boots on.

“This isn’t going to be easy. But it will be worth it. And I would do it a hundred times over if it meant getting my brave little girl back.” Midoriya turned to them and gave them a smile they could not see.

“I think I should get going, I need to-”

“Wait!” Shinsou called, rushing over to Polaroid.

Polaroid stopped and looked up at him with slight confusion.

“Yes Shinsou?” Polaroid asked.

Shinsou pulled his phone from his pocket.

“Lets exchange numbers. I want to talk to you more.” Shinsou told the small vigilante with no shame.

Polaroid on the other hand blushed a bit, his ears going red. 

“O-Oh… okay.” Polaroid got out his phone, “Just to let you know this cannot be tracked in any way. It will only lead you to a random town in Alaska. So please, don’t try. I’ll know.”

“Nice.” Shinsou said as they exchanged numbers. They handed back each other their phones. Polaroid smiled and was about to leave when he suddenly turned back around again.

“Wait! I have an idea!” Polaroid beamed, “Give me your phone!”

Shinsou shrugged and obliged. 

Polaroid tapped on it for a few minutes then handed it back to him.

“Here Shinsou! I found this app that is an extension to Spotify! It lets you see what your buddies are listening to and the other way around in real time. And then you can choose to either listen in or keep listening to your own music! I don’t really have anyone to do it with so I thought we could try! It’s a fun way to get to know each other or even communicate in a way! If you don’t like it you can delete it easily but I thought it would be fun.” Polaroid started to look a little sheepish.

Shinsou smiled and held his phone close.

“I think that sounds awesome. Though I have to warn you that my music taste is weird.” Shinsou grinned.

“Mine’s weirder than yours.”


“Oh I do.”


Polaroid took his leave at that with a little wave and a kind smile.

A few seconds after the door closed Shinsou looked at his parents with mild horror.

“Pops… Dad… I think I’m gay.”

Aizawa slammed his head into the dining room table.



Shinsou laid on his bed and looked up to his ceiling as his headphones played gentle music.

“Oh, circumcise my love for you… It’s far too vapid and aimless. I want to be painless… war soldier, I want closure… and a dollar for the bus back home.”
