Musutafu Japan...many things were strange. Powers just magically developing with a few of the blessed people. Some call them Quirks, Curses...but eventually society decided to go with the term. Ability.

Rumor said that it began way before but eventually went dormant for a while.

It didn't take long for society to accept heroes to help protect the people who never had an ability. Some people used their abilities to harm others and so a society ranking system arrived. To do one test if these people have an ability worth while

Soon some heroes decided to help the new generation to learn how to control their abilities and soon U.A Academy.

Now we join a young man with messy spiky hair who ran towards a fights as a crowd of people were watching a few heroes fighting off a monster.

???: Man, I'm missing it!

The young boy was called Yajin Hidashi as he smiled and watched as he noticed a friend of his that had green hair and one with pink hair.

Yajin: Izuku! Yuji!

Both turned around and smiled as the trio watched.

Yajin: I hope I didn't miss much?

Yuji: Sadly they are gonna finish it.

Izuku: Man, Kamui Woods is so cool! He's new but he's already making quite a name for himself!

Yajin: I keep forgetting how much you fanboy over this.

Izuku chuckled embarrassed about being called out as they saw him begin his Ultimate Move.

Kamui Woods: Lacquered Chain Prison!

Mt. Lady: CANYON CANNON!

The new heroine rushed out to the monster and kicked it's head off as it was then disintegrated from the kick.

Mt. Lady: Piece of cake for the worlds next hottest hero. Hello everyone, I'm Mt. Lady and you don't have to worry about this bum anymore.

Most of the news reporters or even photographers were taking photos while muttering about money shots. Yajin was mostly surprised that she just came out of nowhere and took Kamui's spotlight. But she did fight off the monster quickly.

Yuji: That was a bust. But she is hot...tall and a nice big ass...yeah she's my type of woman.

Yajin: Ain't she blonde?

Yuji: Yeah...like Jennifer Lawrence.

Yajin and Izuku chuckled as they knew their friend was a guy with a certain type of girl but he wasn't a pervert but he did admire them from time to time.

Yajin: I'm actually surprised that the curse was able to escape the veil.

Izuku: It seemed to be a D-Rank Curse so it's not uncommon.

Yajin: Yeah that's true. Anyways, we're heading off to school. See you later Yuji.

Yuji: You too guys.

About 40% of the planet inherited these abilities and used them for either hero work or villainy. With the Government creating the Hero System, veils began to open and people would walk into domains to either fight off villains or curses. The stronger the enemy, the more financial rewards that hero would get.

But one person was the biggest symbol of heroism and power. The Number 1 Hero.

All Might

Yajin: You know Izuku, you really gotta stop monologuing if you're gonna write a book about our society.

Izuku: Sorry but it's just so cool to talk about.

Yajin smiled as he patted his back as they walked to school.

Yajin Hidashi, he was a young man who was good friends growing up with Izuku and often spent most of his days either just doing fun things as children eventually even gaining an ability of his own as he discovered that he could manipulate his own energy and so Yajin dedicated to train and become a hero to protect his family and whoever was in trouble like All Might.

(10 years ago)

Yajin: You know Izuku, it's not really rare to get no power but it doesn't mean you can't help. The veils are always open for many reasons, you can help by using your brain. You're plenty smart.

Izuku: you think?...I can be a hero?...

Yajin: You can...I promise to help you achieve that dream. Together.

Izuku ran to his best friend and hugged him tightly as he cried. With Yajin doing everything he could to soothe his friend and making a vow to help him achieve his dream.

Eventually even learning more of the abilities and veils even learning how some can be used. So Izuku began to learn and document every amazing ability he's seen from a hero or monster/villain.

(Present Time)

Yajin: Hey, do you still have page of Satoru Gojo?

Izuku: Yeah, hold on.

He pulled out a different book and read through it.

Yajin: You mind if I borrow it for tonight, I wanna copy some notes and try to figure out how to do Domain Expansions.

(Yes, Domain Expansions need a curse technique but quirks work almost the same way so people who have curse techniques will be more prone to understand Domain Expansions faster than people who have quirks.)

Izuku: Domain Expansions are like a ultimate move of someone's ability, right? I have tried to study them but I haven't really gotten much work about it.

Yajin: Well we need to have someone who can use Domain Expansions be able to explain how it works but other than Gojo I haven't seen anyone else use Domain Expansions.

Izuku: Yeah.

Both walked to school and once there the day went on as normal but Izuku did get tease by his long time friend, Katsuki Bakugo who was seen as one of the star students because of his power and smarts. Wanting to enter U.A along with Yajin who both had the most potential to enter with their grades and abilities. However that didn't stop him to be a more vocal jerk at times to Izuku who wasn't born with an ability.

Bakugo: You know Deku, the school isn't gonna take in a corpse when you die in the exam. You need to at least stop before you get hurt.

Yajin: Come on Bakugo, back off.

Bakugo: It's just the truth, fighting villains and curses is dangerous and you can't do it without an ability. It's basically suicide.

Yajin hated how Bakugo bullied Izuku at times but he understood why Bakugo did it because before he had confronted Bakugo privately and with not much convincing, Bakugo had told Yajin why he was doing it. It wasn't to be a jerk but to save Izuku from making a mistake that could cost him his life. He hated how stubborn he was but he had to be cold because the world was gonna be colder if someone powerless wanted to join the faction of power.

Yajin: Alright Katsuki, that's enough man.

Bakugo: Alright but just try to think of your options, Deku. You do have other options.

He patted his back a little hard but Izuku did take the hint but he was determined to be a hero. It wasn't just to show the world but to show himself that he could achieve his dream if he worked harder than anyone.

(After School)

Yajin had separated from Izuku to go do some errand runs as the green haired boy walked under a bridge which caught the attention of a sludge villain who wanted a host. While Yajin was on the other side of the city holding a few bags of groceries. 

However he felt a strange feeling as he looked up and saw the sky turn a different color. 

Yajin: A public veil?

He looked around and could feel a very malicious energy that it shivered his spine a bit as he then looked at the direction of the water fountain and saw what seemed to be a woman with revealing clothing throwing a spear right at a guy that seemed to be his age. 

The Spear went through his stomach as he held his stomach and this shocked Yajin as the woman laughed and spread her wings and flew off with the veil disappearing.

Yajin couldn't believe what he saw but quickly he ran and tried to help the guy but he was already losing so much blood and he slowly began to close his eyes but a red glow of light shined which made Yajin close his eyes as a girl with red hair and blue eyes appeared.

Rias: Oh my...this is a little complicated. Excuse me but I need to save this boy.

Yajin was so shocked that he didn't respond but he watched as she began to speak to him and even revealing her own wings.

Rias: Since death is upon you, I will gladly take you in. So from this moment on...you will live for my sake. Issei Hyoudou.

Yajin was more surprised as then he felt a strong presence nearby...it was so haunting and malicious. 

Just what the hell is going on today?!
