Force of Evolution (My Hero Academia x Male Reader)

Dawn of a New Day

Silence permeated through the entire room, as those words stunned the small figure, while Y/n just turned on the light.

The young man began hissing as he squinted and covered his eyes.

"Aaagh! Really!? Did you have to do that!?" He cried out as he held his phone over his eyes like a protective shield

"Who the fuck are you!?" Y/n got into his stance as he backed away, ready to fight if the need arose

"I came to invite you to UA hero training academy. Both on request of the hero, All Might, and...on certain terms with a few of your....relatives..."

He backed away as he sat back down, as smoke puffed out from his body to reveal a smaller form.

It was actually quite startling when he pulled a knife out of nowhere. But I digress.

"Anyways," the small thing put away it's knife for the moment "I am here to invite you. You are going to train soon, so try not to die too fast."

Y/n was stunned at the small creature and it's proposition, but before he could even get his question across, he was answered.

"For someone with seemingly no quirk, you still rushed in to save your friend, risking your life no matter the cause. Now that is a true act of heroism." He heard the creature speak, with no uncertain terms both accepting the compliment, but also having more questions

"How do you know about that? It just happened." Y/n was suspicious of one other thing, but first things first "who are you?..." the creature took a moment to cough into its mouth, stand on the chair, and speak again

"I am known as Nezu. I am the headmaster of UA hero training academy, and you, Y/n, are going to be trained in the ways of hero work!" He screamed out, leaving one question unanswered

"Why did you say 'seemingly' with so much emphasis?" He may have been a slightly dense harem MC, but by no means is he dumb, he knows how to read between the lines of things and take hints.

Mr. Nezu didn't expect him to catch on so quickly, but he went along with him "Yes, there's certainly a reason I did put emphasis on it, Mr. Shigaraki. You see, you have quite a special quirk, which Recovery girl discovered on one of your recent check ups, and so we knew, but we didn't know what that quirk is exactly...until we got a special tip from a reliable source"

Y/n was quite shocked at the news, and he was well over cloud 9 just from knowing he had a quirk after all these years.

"Wait, who tipped you off?" He still had some questions, but it didn't seem like he'd be getting any other info than a shrug from the wierd bear mouse

"We're not entirely sure ourselves, it was anonymous, but it seemed quite credible with the information they gave us, so we can only confirm your recommendation for UA, and that you have a special mutation type quirk." Nezu hung his head, as he gave his solemn apology for not being able to help any further.

"But, due to this source, as well as Recovery Girl's efforts, we know a few specific details behind your quirk and why it couldn't be found at first. But first, we must inform you we do not know all of the details ourselves either." The small creature passed over a thin folder with the label in bold

Confidential: Shigaraki (Eon)

Y/n could tell this would be important, but knew that this wasn't all, as Nezu seemingly had more to say

"After you read this," he looked reluctant, but his arm had been twisted "you will begin your training under the tutelage of..."

Something large and yellow burst through the window, while something quickly wrapped around the both of them

"Oh ho ho~! Were you speaking of little old me~?" The new creature was quite the sight, even for today's individuals

It was quite the strange individual, it bounced around the room like slime, and coiled around the two like a serpent in the shape of a tentacle.

"Uncle Koro!?" Y/n cried out in shock at the surprisingly familiar face.

"That's right kid~!" His grin grew from side to side as he spun around, tossing Nezu and Y/n onto some chairs.

"Yes, Mr. Shigaraki, this will be one of your teachers for your training, your uncle Mr. Shingo, as well as-"

"Now hold on Nezu! Gah!?" Korosensei was startled away by Nezu's glare and his fear of principals "I-I mean Principal Nezu, if you're gonna call me by something other the name my students gave me, then at least get it right. It's Shiniga, not Shingo."

"Alright Mr. Shingo, I guess I'll dock your pay for slight insubordination."

"No, please, don't!" The sight of the two strange adult creatures messing around tormenting each other for fun was enough to break the mood

Y/n chuckled at the two of them, forgetting the serious atmosphere that was just moments ago

"Alright then, I'm in, I may not be real hero material, but I'm in, I will do my best to prove myself, and get into UA Acadamy!" Y/n posed, and stood with his foot on the window sill
"Look out world, for this is the dawn of a new day!" He cheered into the sky, pumped, and ready for whatever adversities the future may hold.

A stirring came from the floor, as a spiky blonde began to awaken

"What...happened?..."

Pishhhh-shi-tunk

"Stop doing that!!"

"She startled me..."

"...get out of my room, please..."

Phone call, down the hall

"Do you think we should get involved?" Akeno listened to their questions as she finally decided to reply.

"No, just send Gouto, we may have use for him as an instructor"

"Yes ma'am"

"I sure hope that this is the right choice..."

A/n-
Hello there everyone, I know it's been awhile, but I've been bogged down with classes, work, and am currently still recovering from a serious respiratory infection, but no worries, I'm not dead yet...just very bad at keeping goals that I set myself to. I'm sorry for not getting thid out sooner, and you're welcome for the fanservice with the crossovers. Now, please comment on who you think this mysterious "gouto" is, since I know at least some will guess right, and others will theorize. The quirk name will make sense when context is given, don't worry.

I'm not dead, and I probably won't for a while, Ciao~!
