(y/n) stretched his arms above his head as he walked home from school on that clear evening day. 

"Man... I'm beat!" said (y/n) to himself as he walked into the pharmacy. 

He made his way to the back towards the clinic where the clerk greeted him. 

"Hey, (y/n). Has it been a month already?" she asked. 

"I suppose so!" he said with a laugh, "Oh, yeah! I made it into U.A.!" 

"Really?!" she said with disbelief, "Congrats!" 

"Eh... It's nothing too big!" 

She rolled her eyes as she handed him a bag full of pills. 

"See you next month!" said (y/n) as he dashed out of the pharmacy. 

____________________________________

(y/n) knocked on the bedroom door before walking in. 

A small smile was on his face as he saw the black-haired woman sitting up in bed, looking out the bedroom window.  

She smiled when she saw him. 

"Hey..." he said in a hushed voice, crouching beside her bed, "You doing okay?" 

"I'm just fine..." she said. 

He placed a cup of water and one of the pills on her nightstand. 

"What about you? Are you having fun? Making friends?" 

"Mom... I'm the last person you should be worrying about..." 

Before she could respond, she began to cough violently. 

(y/n) placed one of his hands over his forehead and then held her hand. 

"The cough is getting worse," muttered (y/n), "You feel warm..." 

"Well, that's why we got the medicine, right?" she laughed. 

She downed the pill and looked at her son. 

"Oh... (y/n)..." she sighed, "Look how you've grown!" 

"Aw... Stop that!" He laughed, kissing her forehead, "Hey... I'm serious... You don't need to worry about me anymore..." 

"I know you feel that way..." said his mother, "I know that you don't want to be a burden, but isn't it a mother's job to worry about her son?"

"Crap! I'm gonna be late!" said (y/n) as he sprinted down the hall to his class. 

He was so focused on running while checking the time, he ran right into someone. 

"Ow..." (y/n) muttered. 

"Are you okay, young man?" 

(y/n) looked up to see a skinny man with yellow hair extending a hand towards him. 

"Thanks!" he said, taking his hand and standing up. 

"Shouldn't you be in class, young one?" 

"R-Right! Thanks for the help!" yelled (y/n) as he ran off. 

"Kids these days..." said the man to himself.

____________________________________

The day was a bit of a bore with all sorts of normal school stuff like Math. 

But after all of that came the highlight of (y/n)'s day: 

Hero Basic Training! 

After summiting a general sketch of his hero costume, (y/n) held a briefcase in his hands that contained his costume. 

"I'm one step closer now..." thought (y/n). 

After being told to meet at training grounds B, (y/n) and some of the other boys went into the locker room to get changed. 

"Hey, did you hear?" asked Kirishima, "All Might's teaching the class! The All Might!" 

"Yeah! Just thinking about gets me all pumped up!" cheered Kaminari. 

(y/n) stepped out of a small changing stall with his hero costume. 

"Wow, (y/n)!" said Midoriya, "You look great!" 

____________________________________ 

AU: (y/n)'s Hero Costume is basically just Goku: Xeno's outfit from Super Dragon Ball Heroes. 

____________________________________

(y/n)'s outfit was black pants and a black shirt with a sleeveless, red jacket. A blue belt was tied around his waist and he has blue wristbands and another blue wrap that covered his calves. 

"Really?" asked (y/n), "I went all out with this costume! It's a bit basic, but there's nothing I'd rather be in!" 

____________________________________ 

The first thing that (y/n) noticed when he walked out to Training Grounds B was all the color. 

The hero costumes of his fellow classmates popped out to his eyes. 

(y/n) could barely contain his excitement at seeing all the hero costumes. 

"Hey! Kyou! Nice hero costume!" 

She wore a leather jacket with a salmon-colored shirt. There were speakers on her legs and arms, presumably to amplify her quirk. 

"T-Thanks..." she blushed, "You look nice too..." 

"I AM HERE!" 

Before they could continue their conversation, a familiar face came down from the sky. 

(y/n) couldn't believe his eyes. 

It was him. 

The Symbol of Peace! 

All Might! 

A lot of the students voiced their excitement over the arrival of the #1 Hero. 

"Now, Young Ones! I know you're excited, but we must begin class!" he yelled in a booming, heroic voice, "We're going to do a training exercise to see what you're capable of!"

"Now we're talking!" thought (y/n). 

"We'll be doing something that I like to call: Heroes vs. Villains! In short: you'll be fighting each other!" 

Everyone looked at each other with confusion. 

"Well... Kind of!" All Might yelled, "In this scenario, Villians have captured a bomb and are prepared to detonate it! I'll be randomly pairing you into groups of two, one group will be heroes and the other will be villains! The objective is simple: Heroes! Either capture the villains or secure the bomb! Villains! Prevent the Heroes from capturing the bomb!" 

Each student drew from lots to determine their role in the exercise. 

(y/n) was a hero along with Fumikage Tokoyami. 

"Glad to be working with you, Tokoyami!" said (y/n) to the crow-headed boy, "Nice robe by the way!" 

Tokoyami nodded. 

When (y/n) saw who was fighting first, he almost laughed. 

Midoriya and Uraraka vs. Iida and Bakugo. 

(y/n) knew Midoriya and Bakugo well enough to the point where he knew that there was bad blood between them, especially on Bakugo's side. 

"Oh, geez... This'll be something..." 

____________________________________

Finally, it was time for (y/n) and Tokoyami to fight. 

"Man! I'm pumped! Midoriya and Todoroki's fight has gotten me all excited!" 

"Indeed, " responded Tokoyami. 

"If you're thinking of strategy," said (y/n), "I've got a pretty good one!" 

(y/n) and Tokoyami stood outside the test building with Yaoyorozu and Kirishima waiting inside. 

Once they got the all-clear from All Might, they headed inside. 

The halls of the building were clear. Not a person in sight. 

"Looks like they'll be waiting for us up there," said Tokoyami. 

"Perfect! That'll make things much easier!" cheered (y/n). 

After getting a bit mixed up in the halls, (y/n) eventually found the bomb. 

Yaoyorozu, armed with a metal staff, and Kaminari stood guard. 

"Hey, guys!" said (y/n), "Mind if I get by you to that bomb?" 

They both took a defensive stance as (y/n) closed his eyes and took a deep breath. 

With his eyes still closed, he began to walk towards the bomb. 

Kirishima was the first to move, attacking him with his hardened body. 

He swung his fists at him, but (y/n) effortlessly dodged them. 

"What's this guy's deal?!" yelled Kirishima, "He's dodging everything with his eyes closed!" 

Yaoyorozu eventually joined the fray, swinging her staff at (y/n), but he was able to dodge that as well. 

Kirishima and Yaoyorozu attacked (y/n) again and again, but he just danced around them with his eyes closed. 

"Stop!" said Yaoyorozu, "He's trying to wear us out!" 

"Huh?! No way?!" yelled Kaminari. 

"He's not trying to beat us... He's trying to buy time..." 

"What are you talking about?" 

"Well, for starters... Where's Tokoyami?" 

Upon hearing his name, (y/n) lunged forwards and struck Kirishima, knocking him back towards the bomb. 

"Damn it!" said Kirishima, "He broke right through my hardened skin in one hit!" 

Yaoyorozu tried to attack him with her staff, but (y/n) dodged it and counterattacked with a powerful punch. 

"Now, Tokoyami!" yelled (y/n) as he opened his eyes. 

Tokoyami ran from out from his hiding place. 

Kirishima and Yaoyorozu tried to stop Tokoyami, but (y/n) stopped their attacks. 

Using Dark Shadow, Tokoyami's Quirk, the bomb was secured. 

"The Heroes win!" yelled All Might over an intercom. 

"Alright!" cheered (y/n), "Nice job, Tokoyami! Dark Shadow!" 

"Aww! It's nothing!" responded Dark Shadow. 

"We should totally team up again soon!" 

"What's with that Quirk, (y/n)?" asked Kirishima. 

"Oh, that?" asked (y/n), "It's something I like to call 'Instinct'!"

____________________________________

"It's a really basic Quirk when you think about it," explained (y/n) to his classmates back at the monitor room while Midoriya furiously wrote down notes, "Basically, by clearing and focusing my mind, my body can automatically react to any on-coming danger!" 

"So that's what was happening!" said Kirishima, "That's one powerful Quirk!" 

"Eh..." said (y/n), "It doesn't really have a lot of offensive capabilities... Most of the strength that I have is a result of outside training. My Quirk doesn't offer a boost in my physical strength, so Instinct is more defensive Quirk..." 

"How long can you keep Instinct active?" asked Midoriya. 

"For as long as I can keep my mind clear. Instinct relies on a clear mind, so if my thoughts begin to dictate my actions, I won't be able to use Instinct." 

"So if we yell at you real loudly, then we can beat Instinct!" said Ashido. 

"Not quite," chuckled (y/n), "Most of the times that my concentration is broken, it's on my own part. I haven't had a lot of instances where my concentration has been broken by outside influence." 

"So can you just dodge anything?" asked Uraraka. 

"Nah. I probably couldn't dodge an explosion from Bakugo at point blank range, to give you an idea, but if I had enough time to clear my mind, I could dodge most attacks! As it stands, Instinct reacts to my mind and allows me to move and react to any danger. It seems that the body can move on its own as it wants!" laughed (y/n). 

"The body moving on its own..." muttered Midoriya, "What an amazing Quirk!" 

____________________________________

Kyouka walked into class the next day to be treated to quite the surprise. 

(y/n) was sitting there, feet on the desk and leaning back in his chair, playing the ukulele. 

"Why did you bring that into class?" asked Kyouka as she sat behind him 

He tilted his head back to look at her. 

"I like music. Don't you?" 

"Yeah... But that seems a bit inappropriate..." muttered Kyouka. 

"Psh! Lighten up! A little music never hurts anyone!" 

(y/n) tilted his head back up and continued to play. 

Somewhere over the rainbow
Way up high
And the dreams that you dream of
Once in a lullaby

(y/n) began to sing quietly to himself as he played which turned some heads of the people close enough to hear the singing. 

Somewhere over the rainbow
Bluebirds fly
And the dreams that you dream of
Dreams really do come true

Iida ran into the class and immediately began to yell at (y/n) for his 'unsightly behavior'. 

"Lighten up, Iida! Aizawa-sensei isn't even here yet!" 

Oh, somewhere over the rainbow
Way up high
And the dreams that you dare to
Why oh, why can't I?

Aizawa walked into the room at (y/n) sat up, but continued to play softly. 

"Stop that," he said while using his scarf to pluck (y/n)'s ukelele right out of his hands. 

"Hey!" 

"What are you, a child?" asked Aizawa. 

"No..." 

As (y/n) sat through the rest of the class, he felt a light tap on his shoulder. 

While still keeping his eyes on Aizawa, (y/n) leaned back to Kyouka. 

"If it's any consolation," muttered Kyouka, "I think you have a nice voice." 

She was thankful that (y/n) didn't turn around to see her blushing face. 

"Thanks," he muttered back, "Be sure to sing for me sometime. I'd like to hear your voice." 

"Y-yeah..." muttered Kyouka. 

"I'll be waiting to hear your song."
