Normally when a child celebrates their birthday it's meant to be a happy and joyous time. However for young Emi that's not the case.

The voices of her parents yelling and arguing in the kitchen echo through the house even into her room where she huddles in the corner hug her knees to her chest with water filled eyes.

This is a nightly occurrence for her and she hated it. She was hopeful that her fourth birthday might be different from a regular day but that was proven to be wrong.

"I'm trying my fucking best! And you can't seem to appreciate that!" Yelled her father

"Well your best isn't good enough! I'm grabbing at scraps to try and feed Emi and you don't seem to care!" Retorted her mother

Her father then growled "Don't you dare turn this on me! You're the one who wastes money on things we don't need. Like shoes and fancy dresses not to mention the gambling problem you got. You care only about yourself that you don't care about me or Emi."

The little girl couldn't take it anymore. She wiped her nose and walked out into the kitchen "STOP IT!"

The two adults turned around to see the little girl. Her mother turned away with a huff while her father sighed "we're sorry sweetie. Just go back to bed okay."

Emi shook her head "no. You two always fight. I don't want this anymore." Spoke the girl in frustration.

Unknown to her and her parents that's when her quirk decided to make its appearance.

Her mother started giggling grabbing Emi and her father's attention both with looks of confusion as the woman continued to giggle. Her fathers lips began to tug upwards before he started to join in with his own chuckle.

Emi watched on with her tear stained eyes as bothe her parents began to laugh louder holding their lips. "W-why are you laughing?" She questioned worriedly

"I-I hahaha don't know Hahahaha." Answered her father with his eyes watering up from laughing so hard.

"What's so funny?!" Frowned Emi clenching her little fists which only somehow managed to make her parents burst into another fit of laughs

Both parents continued to roar with laughter echoing through the entire home occasionally gasping for air. It was then Emi saw the looks in their eyes. Sure they sounded happy and they were smiling from ear to ear but their eyes showed they were in fear.

The look of fear those eyes held burned into her memory in that moment as both parents continued to laugh and laugh with them both rolling on the ground clenching their ribs.

With a few more gasps for air and a few more fits of laughter. Emi was meet with the ringing sound of silence. She stared on in horror as her parents laid on the ground motionless with large grins on their faces.

Her bottom lip began to tremble and her tears began to stream down her face as she looked on at the lifeless bodies of her mother and father.

18 Years Later

Emi walked out of the comedy club with a sigh as she just finished her shift tending the bar. The only reason they kept her employed is because she can use her quirk on the audience when if the comedians on stage were bombing on a set. So she was their fail safe to not look bad on stage.

Despite her love for comedy no one would give her a chance to step up on stage. Mainly due to the fact that everyone thinks she'd just use her quirk to get laughs. So it was automatically assumed she didn't have comedic talent and just relied on her quirk.

She so desperately wanted to prove them all wrong but couldn't find a way to deal it with having her quirk accused of her success. The thought of hero work crossed her mind a few times but since her fourth birthday she didn't really feel like she could ever be heroic for someone.

She just wanted to make people laugh. Not a fake laugh like her quirk creates but a true honest laugh with happiness in it.

It was late at night when she rode on the train back to her apartment she barely noticed she was alone since she was distracted by her notebook writing down stand up routine ideas or half formed jokes in her head.

"Would you like some company beautiful?" Asked a guy the wreaked of alcohol. She glanced up to see a guy in a business suit with strange purple hair that was rounded like balls leaning over the seat looking at her.

The guy looked somewhat familiar to her but she just chalked it up to being a guy that goes to the comedy club. "I'm fine... thank you." She replied in a cold tone.

"Oh don't be like that." Spoke the guy sliding onto the seat beside her.

"I'm not in the mood okay. Just leave me alone." She sighed in annoyance looking at her notebook. That's when she felt his hand on her thigh.

"Come on. We can have fun. I'll make it worth your while." He whispered with a devilish grin that made her feel very uncomfortable. He then proceeded to pull out his wallet and show off his money "name your price babe."

She turned away as she pushed away his hand "I'm not that kind of girl... fuck off"

The guy frowned and grabbed her shoulders pinning her down onto the seat after quickly confirming they were alone. She gasped in shock and tried to fight back but the little perv was stronger then he looked.

"Don't worry I'll be quick." He growled as he reached down to unzip her jeans.

She shook her head with tear filled "No stop! Don't do this please!"

He ignored and the sound of the zipper unzipping made her lose control. By the time the zipper was half undone the guy began to laugh and rolled onto the floor laughing more and more.

Emi's mind began to race at all the possible scenarios that could've happened if this guy had his way. And every thought built up rage with in her causing her to increase the output of her quirk making the attemptive rapist laugh uncontrollably loud.

In her anger she stood drove her heel down onto the mans face busting his nose and teeth. She continued to stomp a few more times until the sound of the mans laughed his mixed in with him gargling and choking on his own blood.

She stared down at him as he gaged once more before his body slumped with a broken smile still present on his face.

Realising what she done Emi quickly grabbed her things and ran off the train at the first stop it came to. When she finally arrived home in her apartment she slid down with her back against the wall running her hands through her hair trying to process what just happened.

The memory of the mans bloody face replayed in her mind and she began to twitch as she remembered the satisfaction she felt driving her foot down breaking teeth. As the memory replayed over and over with sounds with breaking noses and cracking teeth echoing in her mind her lips began to tug in its corners

She began to chuckle to herself as something with in her broke. Shattered even. As her mind continued to replay the events on the train she could only think one thing. "That was Funny."

(A/N: I originally had planned to make this a one shot but decided it might need a few more chapters.

I'm undecided if I should make this a IzukuXEmi fic or not. But it's mainly a villian Emi story with her being heavily based on the joker.

Anyways review and let me know your thoughts.

PLUS ULTRA!!!)
