"It's done!" You fall out of the couch in shock as Montaro burst into the room, holding something in his hand. 

"You are? With what?" You ask. 

"You know, with the 'thing'!" When you don't respond, Montaro sighs in aggravation. "Come on dude, I'll show you. Get the 4 of them. Since they know, I think it'll be alright if they're included too." You nod in agreement. 

"You do the boys, I do the girls." You command. Montaro slightly nods and you two split ways. 

You knock on Mina and Ochako's door, telling them to quickly go to the inventing room. The three of you quickly move, trying to be discreet. Luckily, there are no mishaps along the way. You open the door quickly, usher them in and close the door with a 'bang!'

The device looks like a walkie talkie. Gray, speaker on top, handheld device, that thing.  

"Wow... I never knew this is what it looked like!" Mina gasps in admiration.

"I do, but... I'd rather not remember it..." Ochako mutters, shivering in fear. You look at the girl in pity. 

Seconds later, the door quickly opens and shuts with a 'bang!', like what you did. Mr. Aizawa, Mei, Midoriya, Ochako, Iida, Mina, you, the guy from class 3C and the head of the department are present. 

"Alright! We're all here, so let's see how it wor-"

"Wait. How do you even know to do these things? It's very impressive, considering you are 12." Midoriya asks. 

"I have an extracurricular at school that I join, 'Engineering', so I'm okay with these things. Of course, credit goes to mostly Hatsume, so.." Montaro shrugs and turns the device on and places it on one of the tables. "Let's do it!

After a few seconds, a sound broke through the speaker. 

H-hello? Who is this?

Miko, Miko! It's Montaro! I got blasted into the past!

A gasp can be heard from the girl's voice. 

MONTARO! Montaro! Thank God, I thought you were dead! Hold on, I need to get your parents!

The phone went silent for a while. Mina smirks at Montaro. "So, you know this hero? And, we get to finally meet your parents huh?"

"One, I had to make up a lie. Sorry. She's actually my friend. She and my teacher there made a prototype of this device and slowly upgraded it. Two, yes you will. Prepare to be surprised, I guess." He explains. A voice came back on. 

A male voice is heard. -he's okay? Really? I'll check. Montaro, is that you?

P-papa? 

MONTARO! Babe, get your ass here! He's back here!

You hear some rustling from the phone and Montaro nervously laughs. "Uh, give them a sec."

Monty? Twerp, is that really you? If this is a god damn prank, I swear-

Hey dad! No, it's not a prank. Please believe me. And don't call me Monty. 

Say it kid. 

Now, really?!

Gotta make sure this is our Montaro, not anybody else"s. 

Makes sense, I guess. 

Montaro takes a deep breath whispers something into the device, face red. 

There was a voice crack on the end and the man on the other end laughs. 

'S definitely you kid. Ejirou, get your ass back here. First, you tell me to get my ass here, then you're gone!
I'm coming Katsuki! God, you're so damn impatient. 
F*** off. 

BAKUGOU AND KIRISHIMA ARE HIS PARENTS! OMG OMG OMG OMG OMG OMG OMG! I. CAN'T. BREathe. 

So, done yet? I need to ask a favor.  

Sure kid.

Can you bring the guy that transports me here? Apparently, according to the same guy in the past, the future and past him has to be connected to activate their quirks to send me back. 

Sure can do kid. We're in the police office actually. 

Oh? Then why is Miko with you?

That's what I'd like to know. Got yourself a chick already? 

D-DAD! DON'T SAY IT LIKE-

The man laughs heartily. I'm joking kid! Joking. 

Oh, but can you get the guy?

Sure. 

The other end stay silent and you and Mina take the time to scream it Montaro.

"BAKUGOU AND KIRISHIMA ARE YOUR PARENTS?!" 

"Yep." 

Iida looks like he's about to faint, Midoriya and Ochako are blushing, Hatsume has a glint in her eyes, the guy in 3C looks shock and the teachers looks amused. 

"I never saw it coming." Iida mumbles under his breath. 

"I mean, it is kind of obvious. Like that time Kacchan got really close to Kirishima and stuff."

"BAKUGOU DID WHAT?!" Mina screams. "Oh wait, I got that one already. Never mind." 

The speaker tore through again. 

Kid? You still there? I've got him. Where's the one from the past?

Here. The guy from 3C speaks. 

Hey buddy, you're going to have one hell of a time in the future, so better make some good decisions. 

Yes, sir. I can control my quirk now, and can me from the future do the same please?

Hmm. You assume the man from the future grunts at the device, signalling he is ready. 

"Wait, I wanna say something first!" Montaro interrupts. 

Make it quick kid. Future Bakugou sighs. 

"Alright. Roselle, everyone thank you for helping me. Really, I would've died if it weren't for you guys. Uncle, keep doing what you do and Aunt Mina, please help my parents get together." Mina nods and winks, you thank Montaro back and the trio shakes hands with Montaro. You do this quietly so future Bakugou will not know. 

"I'm done dad. Ready?" Montaro asks. 

Yes. Present 3C man states.

Yes. Future 3C man states. 

"3,2,1,GO!" Montaro yells. 

The 2 quirks are released, and Montaro, bag already in hand, disappears into thin air. After a few more minutes, you can hear him speak from the other end. 

It worked! 
That's good kid! Wait, where's the device?
I must've left it! It's okay dad, it's not like anyone is going to know.
Hmmph. Let's just go home, then?  Deku's brat, Shitty hair, Monty, let's go. 

The phone disconnects after that. 

"AHH! THAT WAS AMAZING! BAKUGOU AND KIRISHIMA ARE PARENTS TO MONTARO! THIS IS GREAT!" You yell. Then, you realize something. 

Wait, if my theory is correct, that means I'll be here. Forever. 

As sad as you are, you can't let that upset you. I mean, you will now forever live in a world filled with heroes. HEROES. Just let it sink in for a second. 

HEROES. YES. Freaking heroes that save the day. It's going to be amazing. And who knows, maybe some other things can be solve and fix. 

I'll be fine. Just fine here.   

(AND THAT'S IT! HOPE Y'ALL ENJOY!)
