(Summary is subject to change along with tags and title. I'm not sure what I'm doing lmao.)

Notes:

This is the first story I've ever written and it's honestly kinda nerve wreaking posting this. The idea to write this just popped into my head after seeing how little MiA fics there are.
Why did I make it into a crossover?
I have no idea but I thought, why the hell not.
I'm not a hundred percent sure where this story is gonna head and I'm also not sure if I'll ever finish it but I'll try.
(I'm also using this as an excuse to get better at writing.)
Thank you for giving this a shot and reviews are always welcomed.

Chapter 1: Prologue: When it all goes to Hell

Chapter Text

All Inko could do was hold her breath and pray that the man would walk past her and Izuku. Earlier that day everything was going great. It was Izuku's 3rd birthday and the Bakugou's, close family friends of the Midoriyas', came over to their apartment to celebrate.

“Look, look Kacchan!” shrieked Izuku in excitement while holding up the brand new All Might figurine.

“HELL YEAH! Come on! Let's play Heroes vs Villains,” exclaimed Katsuki while trying to dragging Izuku to his room, “ I'll be the hero!” Izuku let out on indigent noise. “But I wanna be the hero this time! I'm always the villain.” “ Well that's to bad nerd! Heroes aren't crybabies and you are.”

“W-what? No I'm not!”

“Are too!” Katsuki guffawed. “Look! Your eyes are all wet!”

“Nuh-uh!”

“Yuh-uh!”

“NUH-UH!”

“YUH-UH!”

Before they could continue Mitsuki cut them off with a laugh. “Alright boys, I know you two want to play but it's time for us to go back home, it's getting late. We can back some other time.” Inko hummed in agreement while wrapping up some leftovers for the Bakugous' to take home. “But-!” Masaru piped in with a quick nope before he could continue. “Don't argue brat,” said Mitsuki and with a sly smirk added,” Growing heroes need their sleep. Don’t you want to grow-up big and strong?” Katsuki’s mouth clenched shut and after a minute of deliberation he begrudgingly nodded.

Inko laughed. “Thank you all for coming over it was wonderful. What do you say Izu-kun?” “OH! Thanks for coming and thanks for the gifts!” Izuku replied with a bright smile.

“ Of course,” Mitsuki chuckled and softly smacked Katsuki on the back of the head. “And what do you say Katsuki?”

“Waddya mean?”

She smacks him again slightly harder this time. “

Fine fine. Thanks for enviting us,” he mumbled out and softly added, “Happy birthday nerd.” With a huge grin on his face now Izuku thanked them again. After one more round of goodbyes the Bakugous' left. The Midoriyas’ walk back to the living room both content.With her hands on her hip Inko turns to look back at Izuku. “Alright young man, it's time for you to go to bed. You can play with all your new toys tomorrow.” After a small amount of pleading from her son, Inko lead Izuku to his room and quickly got him situated and into bed. With a kiss to his forehead she softly whispered him happy birthday one last time. “Night mama,” Izuku slurred sleepily,”Love you.” Inko smiled and went to her own room and got ready for sleep.

This is when everything strated to go wrong.

●●●●●●●

It couldn’t have been more than three hours later when a loud crash woke Inko back up. She quickly got up and went out into the hallway. Slowly she peeked her head back out into the living area. Stifling a scream she quickly pulled her head back. There in the middle of the room stood a man softly cursing to himself. A thousand thoughts went through her head until finally screeching to a halt on one -

Izuku!

As quietly as she could she went to his bedroom. “Mama,” came a sleepy voice, “Is that you?” “Yes sweetie. I-I need you to do me a favor,” she replied while glancing back into the hallway nervously, “ I need you to stay v-very quiet. I’m going to t-take you to my r-room and we are gonna hide. Understand?” Izuku now wide awake could only nod in confusion. Inko quickly scoops him up and darts back into her own bedroom. Gently placing Izuku inside her wardrobe she uses her quirk to pull her phone towards her. Shakily she dials the police.

“Musustafu Police Department what’s your emergency?”

Slightly jumping she nervously explains what is happening. “P-please. Send someone quick.” She climbs into the wardrobe with an openly crying Izuku and closes the doors. “Don't w-worry Izu. I’m here; everything will b-be fine,” Inko whispers. Before she can continue loud footsteps could be heard from outside the hallway startling her and causing Izuku to let out a small whimper.

“Ma'am, what’s the current situation?” asks the voice from the phone.

“T-t-the man is by the door,” she frantically whispers while pulling Izuku close to her chest to muffle his cries. “Don't panic ma'am help is on th-“

Boom

The door slamming open cuts the operator off. The muffled footsteps can be heard along with Inko's wildly beating heart and Izuku's suppressed cries.

Thump

Thump

Thump

Thump

All Inko could do was hold her breath and pray that the man would walk past her and Izuku.

Thump

Her heart stops. They stopped right outside the wardrobe….

The doors suddenly swing open hitting the wall with loud bangs! and both Midoriyas' release small screams. Clutching Izuku to her chest she opens her eyes and freezes.

There's nobody there.

Panting, her eyes dart around, searching for anything a sign a clue something- She nearly misses the hand reaching in and grabbing her baby boy.

IZUKU!”

MOMMY!”

The rest of the mans body appears from a slowly forming portal she had missed seeing in her panic. The police operator is all but forgotten for the intruder with her son. The man dressed in all black stares at her intently with his toxic yellow eyes while showing off his shark like teeth in a crazed smile. Izuku struggles in his grip and tries to punch and kick his way free. The man just chuckles at his pitiful attempts. In her manic state Inko gets ready to make a wild grab for the man before a loud voice stops her.

“Stop right there villain!” shouts the voice by the door.

Who!? Womancoustumeiceformingatthehands-herothankgodfinally

Before the hero could come closer the man shrieks at her to stop. “Don’t move! Any of you get closer and tha boy gets it!” He flicks his wrist.

Shink

Time stops.

Inko could only stare in horror as the villain brought a knife to her son's- her babys'- neck. Izuku's cries get louder and his attempts to escape stop.

The hero (Ice Queen- a voice that suspiciously sounds like Izuku- supplies her in the back of her mind) glares in disgust.

“Could you stoop any lower?” Ice Queen spits out. The man only grins in response. They stare stare at each other for a minute before everything goes straight to hell.

Ice Queen ventures to make a grab for her son who could only shriek as the man stumbles backwards, clearly not expecting the hero to actually make a move. During the small rush he drops the knife and tries to make a portal. He finally succumbs to gravity and falls- not before dropping Izuku

Straight into the portal

The man crashes into a nightstand knocking himself out and Inko screams.

●●●●●●●●

It isn't until about an hour later when the man is taken into custody and the police get a report from a regretful looking Ice Queen that Inko finally talks to someone.

A rather tired looking person wearing a tan trench coat and fedora comes up and introduces himself as Detective Tsukauchi.

“We got bad news and good news. Good news is: we got a name and a quirk from the villain,” Tsukauchi sighs, “His name is Sunpō Kei and his quirk is called Dimensional Portals. The culprit can open portals to different worlds.”

Inko quietly sobs. “Just please tell me you can find my son.”

He grimaces. “There's the bad news. Because of all the panic, Sunpō isn't sure where the portal opened up to. “ Tsukauchi runs a hand against his forehead and hypes himself up to tell the woman even more devastating news. Swallowing what feels like a brick he just goes for it. “Sunpō also admitted to only being able to open the same portal twice. To and from the place. It's going to be difficult to properly locate your son.” And all Inko can do is wail.

In a land far away, deep in the Abyss, a child? wakes up.
