"I'm gonna be late! I'm gonna be late!" thought (y/n) as he sprinted through the halls of U.A, desperately trying to get to his class before it started. 

"Young man!" 

(y/n) was about the dash around another corner before he was called out to by a familiar face. 

It was that skinny, yellow-haired man. 

"Oh! Hey, Mr... Uh... I'm sorry, but I don't know your name!" 

"It's... uh... Mr. Toshinori!" said the man, clearly flustered when asked about his name. 

"It was nice seeing you again, Mr. Toshinori, but I've gotta get to class." 

"Wait. I heard about the U.S.J." 

"Right... That whole situation..." said (y/n), scratching his head a bit. 

"I heard about how you threw yourself at that monster. Why would you do that?" Toshinori asked. 

"Well... I don't know... I just couldn't sit there and do nothing while All Might fought that thing..." said (y/n). 

"You couldn't sit there, even though you knew that it was dangerous?" 

"I had no other choice..." muttered (y/n), "If I didn't jump in, then All Might might've died... If I didn't jump in... She would have..." 

"She?" Toshinori asked. 

"S-She?!" stuttered (y/n), "Did I say 'she'"? 

"In any case," said Toshinori, "Even if your concerns are great and even though you may think you can win, it's not worth risking your life. Take care of yourself, young man." 

"Thanks for the advice," smiled (y/n) before running off to his class.

"That just wraps up the U.S.J. Incident," said Aizawa, reading off of the paper about the damage. 

"Although the unnerving behavior and abilities of the monster, Nomu, is concerning," said the Principal Nezu, "We must trust our friends in Law Enforcement and hope that the police can extract any information from Nomu. It seems that this unfortunate chapter at the U.S.J. has come to a close..." 

"There's one thing that concerns me!" yelled out Present Mic, "At around the same time that the intense battle for the U.S.J. was goin' down, there was a crazy earthquake that came from the facility!" 

"About that..." interjected Toshinori, "I believe it was one of your students, Aizawa." 

"A-A student?!" yelled Present Mic. 

"Indeed. After nearly being killed by Nomu after recklessly engaging the monster in battle, his Quirk manifested itself and gave (y/n) an incredible power that matched Nomu. Although the power soon vanished from him, there was a moment where the whole facility shook when his power became known..." 

"I thought it had something to do with the League of Villians, but for a mere student to generate that kind of power..." muttered Nezu, "He could become one of the greatest heroes the world has ever seen!"

"I've watched it a couple of time on TV in previous years, but knowing that I'll be able to compete in the U.A. Sports Festival this time around is getting me all excited!" cheered (y/n). 

"I'm surprised that they're still holding the festival considering what happened at the U.S.J.," said Yaoyorozu. 

"Aizawa-sensei did say that the competition was too important to cancel," stated Todoroki. 

"What does that mean?" asked Kaminari. 

"To cancel the festival would mean that we acknowledge the League of Villians as a legitimate threat," responded Tokoyami, "The festival will continue to show that we will not be stopped by some petty attack." 

"That's right!" yelled Ochaco, "Everyone! I'm gonna do my best and win!" 

"Yeah!" shouted Kaminari. 

"That's the spirit!" yelled Kirishima.

"Go all out, Ochaco!" cheered (y/n). 

"Speaking of going all out," said Midoryia, "Would I be wrong in assuming that we'll see your full power, (y/n)?" 

"Oh, you mean..." 

"That's right!" shouted Mina, "You went crazy back at the U.S.J.! What was that all about?!" 

"Do tell," said Kyouka, leaning forward to listen to (y/n)'s response. 

"Uh... Well..." 

Everyone's eyes were on (y/n) as he tried to come up with a response. 

"To be quite honest, I'm not really sure what happened!" (y/n) laughed, "If I had to guess, I would say that my Quirk had some sort of fight or flight response to that near-death situation. At that moment, it seemed that I was able to tap into the complete power of Instinct." 

"The complete power of Instinct..." muttered Midoryia as he jotted everything down in his notebook. 

"The whole thing felt super weird though..." (y/n) said, "It's like my mind was running on autopilot and I could only 'feel', per se." 

"That's to be expected," said Todoroki, "You did say your Quirk is most effective with a clear mind." 

"So what did it feel like?" asked Kyouka. 

(y/n) paused a bit before answering. 

"Terrifying, but exhilarating at the same time!" 

 "Do you have a name for it?" asked Kyouka. 

"A name for it? Geez... I don't know..." muttered (y/n), "Oh! I got it! I think I'll call it Ultra Instinct!" 

"Ultra Instinct?" said Kyouka, rolling her eyes a bit. 

"It's Instinct, but Ultra Powerful! Ultra Instinct!" 

"You... might have to work on the naming a bit, (y/n)..." said Mina, "It's kinda lame..." 

"What?! It's super cool!"

Come on Elieen, tah-loo-ray-ay

Come on Elieen, tah-loo-ray-ay 

Now you're full grown

Now you have shown

Oh, Eileen!

(y/n) sung into the microphone while swaying to the music provided by Kyouka's keyboard. 

Say, come on Eileen 

These things, they are real and I know 

How you feel...

Kyouka couldn't help but giggle to herself about how much (y/n) was getting into this, moving his body and walking around the room while singing. 

Now I must say more than ever, things round here have changed.

I say, too-ra-loo-ra, too-la-roo-rye-ay! 

Come on Eileen

Oh, I swear what he means!

At this moment, you mean everything! 

(y/n) turned to Kyouka as he was singing as if he was directly talking to her, making her blush a bit as she played. 

You in that dress, my thoughts I confess 

Verge on dirty 

Aah, Come on Eileen! 

Kyouka laughed and clapped as (y/n) took a mock bow. 

"Nice place you've got goin' on here!" complimented (y/n). 

"It's not much..." muttered Kyouka, clearly embarrassed about the boy that she had brought home. 

"You know..." she said, "You have a really nice voice."

"So you say," said (y/n) before laying on the floor, "I'd love to hear you sing sometime!" 

"M-me?!" she stuttered, "T-there's no way I could!" 

"Come on!" encouraged (y/n), sitting up to look at her. 

"I couldn't possibly..." muttered Kyouka, blushing while hiding her face in her hands. 

"Damn," said (y/n), falling back on the floor, "I'd love to hear your voice sometime." 

After a bit of silence, Kyouka finally spoke again.

"Scared about the Sports Festival?" Kyouka asked.

"Are you?" he asked. 

"I'm the one asking the questions here," said Kyouka, crossing her arms. 

"Not in the slightest!" he yelled, throwing his fists in the air. 

"What am I ever going to do with you?" she asked, "If you're going to lie down, do it on the couch. You'll hurt your back."

Finally, the day of the Sports Festival was here. 

After an introduction from the R-rated hero Midnight and Bakugo's unorthodox pledge, the preliminaries of the Festival began. 

The first task was a 4-kilometer Obstacle Race and everyone instantly tried to get a leg up on the competition. 

Every student from U.A.'s hero course began to struggle through the stadium's door. 

Todoroki suddenly froze the ground and raced ahead of everyone. 

Much to his dismay, many of his fellow students were able to avoid Todoroki's attack. 

"Ice, huh?" asked (y/n), almost slipping while running. 

(y/n) ran for a bit before stopping in his place, taking a deep breath and letting all the other competitors run past him. 

As the others made their way through the obstacle course, villain robots from the entrance exam attack the contestants. 

Todoroki made another grand display of his Ice Quirk, using it to destroy the large villain bot in front of him. 

The frozen enemy toppled on top of Kirishima, but his Hardening Quirk protected him from the impact. 

As everyone raced to the finish, Midoryia realized that (y/n) was still at the start. 

"What's he doing?!" thought Midoryia, "If he doesn't get moving, then he'll lose for sure!" 

"Keep up, damn Deku!" yelled Bakugo as he shot by Midoryia using his Quirk to propel himself forward. 

"That's right! I've got to win this! I've got to become the next All Might!" 

After crossing a seemingly perilous cliffside, the final obstacle made itself known. 

Mines (non-lethal, of course) were placed all over the ground, making the leader of the race, Todoroki, falter behind as he cautiously made his way over the final obstacle to victory.  

"Keep up, slowpoke!" yelled Bakugo as he hovered over the ground using his Quirk. 

Midoryia, who was starting to lag behind, had an idea: 

Use the scrap metal from one of the Zero-Point Robots to shield himself from a direct blast from one of the mines, thus using the kinetic energy to launch him across the finish line. 

Midoryia put his plan into action, hitting one of the mines with the metal sheet. 

The explosion sent him flying past Todoroki and Bakugo as he made his final bid for the finish line. 

Back at the starting line, (y/n) focused his mind and breathed in an out. 

In and out, wind began to approach and move away from (y/n) with every inhale and exhale. 

(y/n) opened his eyes and got positioned himself into something akin to a track start. 

All Might, seeing the silver glow in (y/n)'s eyes, knew that he was tapping into the unknown properties of his Quirk. 

(y/n) blasted off from the starting point and shot his way through every obstacle with extreme speed. 

Everything was a blur in (y/n)'s eyes as he instantly moved faster than anyone else in the race, causing a powerful shockwave to emanate behind him. 

He was coming up on the three leaders of the race: Midoryia, Todoroki, and Bakugo. 

He shot right past the finish line and crashed into the floor below. 

"(y/n)! Are you okay?!" asked Midoryia as he ran up to him. 

"Did I win?" groaned (y/n). 

"Well... You came in 4th place..." 

"Aw, damn it!" said (y/n) in defeat. 

"That was an amazing spectacle of speed," said Todoroki, the second-place contestant, "But it was too late. We crossed the finish line just before you shot by us." 

"God damn it."
