Fenrix Unbound

3 hours later at a Yaoyorozu hospital we find a four year old boy with a pair of wolf ears and a matching tail laying on his side unconscious, and a similarly young girl sleeping while holding onto said tail and giggling in her sleep when it moves, tickling her.

************************************************

'Ugh, did anybody get that license plate, my head is killing me. WAIT! Someone has my tail! Oh, it's just Momo. MOMO!'

"*Momo! Momo, wake up.*"

"Huh?"

'Oh my God she's adorable!'

"Momo are you okay?"

"Yep. You healed me, you're like a hero!"

"A hero, huh? Maybe that's what I should do, become a hero, so I can protect you."

"But, but I want to protect you!"

"Oh? Why's that?"

"Because I was getting a drink one night and I heard Okaa-san tell Otou-san that you and I will get married when we grow up. She had the scary smile and everything."

'Why the hell are they discussing THAT late at night? More importantly, Momo heard you!'

"Hmm. I guess that IS a good reason, but do you want to marry me Momo?"

She looked away shyly, and nodded.

'Seriously! Why is she so cute!'

"Alright then, we're engaged, but you have to tell me if you change your mind, okay?"

Then, out of the corner of my eye, I see the door move slightly. Shit. I motion to Momo to keep quiet and then I move silently to the door and yank it open. As you know, anime logic applies to this world too, so, when I opened the door so fast four people fell face first on the floor. From right to left, it's Mom, Dad, Jin-san, and some guy in a lab coat who I'm guessing is a doctor. Gossip mongers, the lot. Mom and Dad I expected, the doctor I don't know and therefore can't judge, but Jin-san? I'll put it this way: E'tu Jin-san?

I look down at them and say "if you're done gathering gossip may we begin?"

*Ahem* "Yes. Hello there Kaen, I am Doctor Kishitani Shinra, specialist in studying new and unusual quirks. We've already logged what we've seen so far, please be sure and let me know if anything comes up during your stay here. As it stands you are healthy enough to be released tomorrow with a one night stay for caution. Oh, and what would you like to call your quirk? I ask because we need to register it."

'I have been thinking about this for literal years, and finally time.'

"Call it Fenrix Unbound."

"Okay, but can you tell me why?"

"It's named after the world wolf, Fenrir, who could command ice, the chains that bound him who was a God being, Gleipnir, and the bird of eternal flames, the Phoenix."

"You seem to have put a lot of thought into this, young man."

"I know that I'm adopted, and it's better to know your birth parents quirks if you can, so I asked Jin-san what their quirks were years ago."

"Really?"

"Ah, that's right he did ask me. His birth Father Hokkyoku Kori was able to change into a wolf made of ice, he committed suicide following the death of his wife. His birth mother Hokkyoku Hi had the ability to summon birds made of fire, but she had a weak constitution, which resulted in her death at childbirth."

"Hey, is it really alright to say it like that in front of him?"

"Yes. He has known about this for years and he doesn't blame himself which he shouldn't."

During Jin-san and Kishitani-sensei's conversation Mom, Dad, and Momo were hugging me.

"Well, as I'm sure you heard, Momo and I want to be heroes, do you approve?"

"Of course my pup." Mom said while glaring at Dad, with a portent of a week on the couch, should he say no.

"Oh funnny you should say that. I've had this funny feeling since I woke up. I want to try something."

I then imagined turning into a wolf, and poof, in a cold burst of mist Kaen was gone and a puppy was sitting on the bed.

I was immediately picked up by Momo who was squealing with joy and put on her lap, while everyone else looked dumbfounded.

"Hmm... I'm not sure if I should have done that now. Good my voice sounds normal, it would have been awful if I could only bark. Oh, look Momo they all passed out. Should we go back to sleep too?"

"Do I get to cuddle you?"

*sigh*"Yes you can."

"Then let's nap."

************************************************

10 years later we see a 14 year old Momo standing outside a class at Aldera Junior High with a bright blue bird on her shoulder.

"Class we have two new exchange students who will be attending school here with us. You can come in now."

"Thank you, Satou-sensei."

"Please introduce yourself to- Wait a second, um where is Kaen-kun?"

The bird on Momo's shoulder raised a wing but made no sound.

"Um, Kaen-kun, you know you're not supposed to be using your quirk, right?"

The bird hopped of of Momo's shoulder and settle on the ground, then it burst into a warm smoke.

*sigh* "Fine." I say as the smoke dissipates.

"Would you please introduce yourself to the class?"

"Okay, I am Hokkyoku Kaen and this is my fiance, Yaoyorozu Momo, we are here to make friends and practice socializing in a normal setting before we apply to U.A."

"Kaen! You weren't supposed to mention us being engaged."

"Why not?"

"Because it's embarrassing!"

"Being engaged to me is embarrassing?"

"N-no it's not like that."

"Would you two please stop flirting and take your seats."

""Yes, Satou-sensei.""

There was a sudden explosion in the classroom next to ours.

'Well, at least I know where Bakugo is, I guess. Plan copy most of the MHA fanfics I read in my last life, and make sure greenie gets his quirk is a go. Let's have some fun.'
