AN: Hello, and welcome to my new story: Boku no Hero Academia: Deku the Ajin!

I just want to say thank you for those who might read, and like this story.

Now, before I forget anything, I would like to point out a few things. The story isn't a crossover, it'll have some elements from the Ajin series. The Ajin and their abilities will be considered Quirks, so there might be others with this rare "Ajin-Quirk". Those with the "Ajin-Quirk" aren't hunted down and experimented by the government. Deku, will not only be an Ajin, but he'll also have "One-For-All" as well. Also, here are some the differences between the Ghosts' voice, and the normal voice:

"Kacchan!" - Normal Voice.

"Kacchan!" - Ghost Voice.

Finally, if you haven't noticed, I'm going to -

Kacchan: "HURRY THE HELL UP!"

Deku: "Kacchan, calm down!"

HOLY HELL! How - Oh yeah. I decided to do this. So yeah, the BNHA crew will begin to appear at each chapter. Now let's get this chapter going. Deku, Bakugou, will you say the following?

Deku: "Okay!"

Kacchan: "Fine."

Deku: "Boku no Hero Academia all its characters belongs to Kōhei Horikoshi. Ajin: Demi-Human and its characters belong to Gamon Sakurai."

Kacchan: "HERE WE GO!"

Ten Years Ago -

A small boy with black hair, that had a green tint, alongside green eyes, was defending another boy, who was on the ground, crying. This boy was timidly standing up against three other boys, the leader with blonde hair and red eyes. As the two looked at each other, the green-haired boy said,

"Kacchan, why are you dong this!? Can't you see that he's crying?"

"Shut it, Deku! And you're one to talk!"

The one called Deku was indeed crying, scared that he was going up against Kacchan and his goons, all of which who have Quirks. Annoyed, Kacchan shouted,

"That's it! GET HIM!"

Instead of going after the boy, the three boys went after Deku, with Kacchan using his Quirk, Explosion, to make his punches hurt harder. Deku was ruised at this point and thought to himself:

This can't be happening...this can't be happening...this...this...

"THIS CAN'T BE HAPPENING!"

As Deku screamed his lungs out, Kacchan and his goons all froze, confusing Deku. As he managed to get out of the hold he was in, he looked at Kacchan, who was still paralyzed. His confusion turned into fear, seeing that his former friend wasn't moving. As he slowly walked away, he began to talk to himself.

"What's happening?"

"What's happening?"

The small child turned around, and his eyes widened at what he saw. It was a humanoid figure, made out of some odd material that reminded him of black wrapping, that was 2 meters tall, with horns and a smile that reminded him of his idol, All Might. The figure squatted in front of him, looking at him with no face. It rose one of it's clawed hands, frightening Deku, however, the fear was gone, seeing that it began to pet him. It spoke again, looking at Kacchan,

"Can't you see that he's crying?"

In the Hospital -

After the paramedics took the boys to the hospital, Deku was being reexamined due to the fact he was considered to be 'Quirk-less'. As the doctor came in, he was greeted with Deku and his mother, Inko Midoriya. His mother asked,

"Doctor, you said that Izuku was 'Quirk-less', how is this possible?"

"Well, after having him examined again, your son has acquired a rather...rare Quirk. A Quirk that was only used by a single person, which was years ago."

"What is it?"

"It's called Ajin. Basically, Izuku has the ability to heal from life-threatening injuries, able to regenerate limbs, and can temporarily paralyze those around him with a simple scream."

At the mention of his paralyzing scream, Deku, or Izuku, as it is his given name, remembered Kacchan, or by his true name, Katsuki Bakugou, was paralyzed by his scream. The doctor seemed to know what Izuku was thinking, and told him,

"Don't worry, the affects have worn off, and those boys are okay."

"Oh thank goodness..."

"Now, is there anything else bothering you about your Quirk?"

"Yeah, what about the Ghost?"

Both adults looked at each other, before looking back at the child, both with confused expressions on their faces. Inko asked her son,

"Izuku, honey, what Ghost?"

"The Ghost! He was standing behind after I paralyzed Kacchan and the others!"

"What did this 'Ghost' look like?"

"He was really tall and skinny, made out of black wrapping I think, and had horns and a smile like All Might!"

The doctor tried to come up with somethingfor this, but he didn't knew what he was talking about. He said,

"Izuku, I think that this 'Ghost' was a figment of your imagination."

"But..."

As Deku tried to think of a reason for the adults to believe, He looked at the corner of the room, and saw the Ghost standing there, looking at him. The Ghost told him,

"What's Happening?"

Ten Years Later: Present Day -

After ten years, Deku, now a teenage boy, was heading to school, until something happened, gaining his attention. He was dressed in his black gakuran, and was walking towards a group of people, watching a giant monster fighting other heroes.

He pulled out a small notebook, filled with details about multiple heroes, and on what to do when encountering Villains. As he began to write down more details, an old man said,

"Are you taking notes, kid? That makes you a fanboy, aren't you?"

"Well...you could say that. But I'm planning to enroll to U.A. High!"

"Good luck with that, kid."

After the Villain was defeated by Heroes, both new and old, everyone went back to what they were doing. As Deku was running towards his school, he slowed down, and saw something that surprised him.

Standing in the entrance of the school, was the Ghost, or 'Ghost' as Deku officially named him. Deku simply smiled at him, and silently said,

"Hey, Ghost. How are you?"

"..."

"Oh, I'm doing alright."

"...I'm doing alright."

Ghost began to walk towards him, and left. As Deku watched him leave, he heard that homeroom started, making him late. As he ran inside the building, he had a single thought:

It's been nearly ten years since Ghost and I became acquainted. I wonder if there's anyone else with the Ajin-Quirk?

AN: And that was the first chapter of this new story! So what did you guys think of it?

Kacchan: "I FIND IT BULLSHIT, I MEAN, DEKU ONE-SHOTS ME!"

Deku: "Technically, I screamed at you, and you..."

Well, before Bakugou kills you, Deku, do you want to say it?

Deku: "See ya later!"
