The Demon Slayer:

Chapter 1: Quirkless?

100 Years Ago all demons were defeated, then after that quirks started to appear, some of the demon slayers hypothesized that without the darkness to balance out the light the world created quirks in order to balance the light and dark.

The number of demon slayers diminished after the introduction of quirks, some demon slayers became heroes in an attempt to keep their ideals of peace alive. Now the numbers of the demon slayers dwindle at 70 strong, however these few are very strong, the average slayer being able to perform constant total concentration*. Many of the demon slayers decided to travel the world, and spread their ideals, hoping to create a better world. Only 4 stayed in Japan, the Number 1 Hero All Might the Hashira of wind. Endeavour, the number two hero, the Hashira of Flames and Edgeshot, the number 5 Hero, the Hashira of mist. The last member in japan being the leader of the corps, his name is unknown to all but the pillars, who refer to him as One-sama.

Hasashi Midoriya, the water pillar had left his family in an attempt to revive the corps, overseas. He left is one and only family member in the care of One-sama, and he has been trained in constant total breath concertation, water breathing and thunder breathing. Izuku is now 14 years old and is on his way to his high school, Aldera High.

The Demon Slayer in Midoriya stands at around 174cm, has emerald eyes and burgundy hair that blends into green the further back it goes, Izuku's hair is rather long and has tied it into a messy ponytail. Midoriya is a rather well built fellow and has a rather dauting scar on the top left side of his face. Izuku is a rather caring boy, he looks out for everyone no matter their age, like a brotherly figure and has a high tolerance for bullshit i.e Katsuki Bakugo, however today his tolerance would hit its limit.

It is lunch time and Izuku is sitting with his friends, talking about what hero team up could beat All Might. All was well until one Katsuki Bakugo and his lackies decided to 'join' them.

"OI DEKU!" Katsuki screams as he slams his explosive hand on the table. Making everyone but the said boy flinch

"Hello to you Kastuki Bakugo, how can I help you?" Izuku said with a carefree voice while eating his bento.

"SHUT UP DEKU! YOU QUIRKLESS FUCK! I want your lunch today, as the future number one hero I need to eat healthy and your bento looks it!" the ash blonde demanded

"I'm sorry Kaachan, I can't do that seeing as that would leave me without lunch, and after all I want to be a hero as well. So I need to keep up my appetite" Izuku responds, still eating his bento.

"Tch, never mind you've already eaten half of it… I guess I'll go eat someone else's lunch" Katsuki explained before walking over to a table with people in the lower grade in it. Katsuki then started to yell at a blonde girl "OI EXTRA GIVE ME YOUR LUNCH!"

"Y-yes Bakugo-sempai!" the girl said before offering her lunch to the bully.

Izuku had just finished his Bento, never had Katsuki gone this low, sure he took Midoriya's lunch one or two times and Izuku let that slide for the greater benefit of the school, but targeting others was one step too far. Izuku grabbed his empty bento and flung it at Katsuki, hitting him dead on the head. Izuku then went to sip on his milk.

"WHICH ONE OF YOU EXTRA'S DID THAT!?" Bakugo asked furiously

Izuku chuckled and then spoke "Well you did say that you wanted my bento, did you not?"

"DO YOU WANT TO DIE YOU DAMN NERD!?" Bakugo shouted

"No Kaachan, but if you want to settle this, how about we take it to the gym? No holds barred and an audience?" Izuku said before standing up and heading towards the locker bay.

"YOU WILL DIE YOU DAMN QUIRKLESS DEKU!" Bakugo shouted before storming to the gym.

The crowd was murmuring, the two most 'popular' kids in the school were going to go at it.

"Who's gonna win? Bakugo-sempai or Midoriya-Sempai?"

"Well Bakugo-sempai has a rather strong quirk and as far as we know Midoriya-sempai doesn't have one"

"I hope Midoriya-sempai wins, but I don't think he will"

"Nah Bakugo-sempai's way to strong"

-Aldera Gym-

All the students in the school had flocked to the gym stands to watch this major even occur, Bakugo was waiting with his lackies in the middle of the gym. Then the door opened and entered Izuku wielding a wooden Katana.

"WHATS THAT YOU GOT THERE DEKU! SCARED BECAUSE YOUR'RE QUIRKLESS!?"

Izuku just continued to walk and then stopped when he was 5 meters away. Izuku took a stance where it made the wooden sword look like it was sheathed. He closed his eyes and started to breathe slowly. He opened his eyes to reveal that the irises of his eyes have transformed into a Ying-Yang symbol

"SO YOU DO HAVE A QUIRK DEKU! NO MATTER I WILL BEAT YOUR WORTHLESS ASS!" Bakugo shouted with a grin before charging forward.

Izuku then whispered 'Thunder Breathing: First Style: Thunderclap and Flash'

In an instant Izuku was on the other side of the gym, what he left behind was the crackling of lighting and a Bakugo that was vomiting.

Izuku walked out of the gym leaving a startled crowd.

Izuku walked to his locker and then noticed something off, he looked around, and it was like the world was moving in slow motion. He heard the bell ring, but it was slower, he saw a bird flying in the hallway, it was slower.

The rest of the day went slowly for Izuku Midoriya. He left school on for his normal trek to the mountains, where he lived with One-sama. The trip took him 3 hours each way, Izuku did not see the reasoning for him to travel so much when he could go to a nearby school.

Though now that Izuku had completed his training in becoming a demon slayer he had more spare time on his hands. Izuku loved to walk, and immerse himself in nature, there was some aura that he could sense which made him calm. One of the places that was close with nature was the place Izuku dubbed as 'Rich way' where all the wealthy people of japan lived, people from the owners of Yaoyurozu Corp to Earthern Fire Industries. There was also lodging for the Kizoku Academy, which consisted of the children of the richest families in Japan, all sending their sons and daughters there. Izuku was walking past that lodging right now, and he could smell greed and arrogance.

Now decked out in a family heirloom a black and seafoam green checkered haori, coving his school uniform. Izuku made his way past that lodging, where he found a girl, with black hair and a spiky ponytail being cornered by what seemed to be boys.

"Yaoyurozu-chan please date me, my family has quite the amazing estate" one said

"No you must not date this peasant Yaoyurozu-chan, my estate is much bigger than his and I am set to inherit my family fortune when I become of age." Another said

"Yaoyurozu-chan, please forgive these fools I have a wealthy family and I also have a powerful quirk that will surely get me into U.A's hero course" a blonde haired boy stated

Izuku was shocked by these rich school kids, here he was taking a peaceful walk and then he had to stumble into this mess. 'Oh well as an Honorable demon slayer and a hopeful hero I should do something' Izuku thought before shouting "Oi, would you leave her alone. She clearly dosen't want anything to do with you!"

The three rich kids turned around and snarled at Izuku. "And who do you think you are pleb?" they all shouted

Izuku just laughed and then responded "just some random guy"

"Well Random Guy, you should leave, this issue if far above your pay grade" the blonde boy shouted back

Izuku then started to walk towards the boys while speaking "Of course it's above my pay grade, I don't have a job!"

This earnt a giggle from the girl.

Izuku was now 3 meters infront of the group and then sat down, cross legged and pulled out his phone, beginning to scroll through his Instagram feed.

"What do you think you are doing peasant, this is private property!" one shouted

Izuku then looked at the boy with a deadpan look, "Dude, I'm sitting on the footpath, this is public property" Izuku then went back to scrolling through Instagram.

The three rich kids then walked over to and circled Izuku. "Listen pleb, my quirk is rope bind, I can shoot roped out of my hands and bind you within an instant. You have no chance against a quirk like mine, I will be getting into U.A after all!"

Izuku replied "good for you" no even taking his focus away from his phone. The girl was watching these events folding out with awe.

Izuku then stood up and looked one of the boys directly in his eyes. "I'm going to walk forward now" he said as he walked through the said boy.

The rope quirk user used his quirk to grab the wooden pole that was sticking outside Izuku's bag. He grasped it and then shouted "What's this pole for pleb? Your sickly grandmother that can't afford to get basic treatment?"

Izuku then turned around and looked that boy directly in the eyes "I never knew my grandmother"

"Well I don't care… but for causing us trouble [The boy snaps the wooden Katana over his knee] this is your punishment!"

'One-sama isn't going to be happy that my katana broke!' Izuku thought as he walked over to the girl. "Are you okay? Sorry for causing a ruckus Miss-?"

"Yaoyurozu" the girl spoke, with a sweet tone

"Do you want me to walk you home Yaoyurozu-san?" Izuku responded with a kind voice

The girl remained speechless, and a little bit flustered "Sorry if I imposed myself on you Yaoyuro-"

"HEY PLEB! DON'T IGNORE US… AND THAT'S YAOYUROZU-SAMA TO YOU TRASH!" one boy spoke

Izuku chuckled and then asked the girl "Are they bothering you?"

The girl nodded, "Do you want me to do anything about that?"

The girl hesitated, then nodded.

Izuku then smiled, a kind smile "Okay, stay right here this will be over soon"

Yoayurozu smiled as Izuku turned around. "You know, since you assaulted me I can use force to stop all three of you"

"Enough talk pleb leave and all shall be forgotten" the rope user stated

"Nah, I think I'll stay!"
