Chapter 1: Killua

Describing it as weird, would be an understatement. The young white/silver-haired former assassin would describe it as crazy.

Between breezing through the Hunter Exam, to fighting big, giant Chimera Ants, being thrown into different dimension filled with Heroes wouldn't be that surprising.

But there he was. On the streets. In a whole different world.

There were all kinds of different people, as Killua could see. A man with horns out of his head. A woman with an extra pair of arms. Anything you could imagine.

But what really caught his eye, was the giant shark thief wrecking a train station.

"Tatooin Station." Killua read. Even though this world used a different kind of writing system, because of his father and mother he got introduced to a lot of different languages for missions.

This was known as Kanji, as Killua understood it. And the country that used Kanji, would be the Japanese language. Which meant-

"Japan?" The young boy questioned himself.

It was weird.

Japan was also a country in his world. But there weren't any people with superpowers there that didn't emerge from Nen. So he was basically in his own world, but it was different. In many ways.

Too many to list, as Killua is thrown out of his own thoughts by being bumped into by a boy around his age.

His eyes widened as he saw familiar green hair with dark parts in it.

"Go-" Killua stopped himself. Another look at the boy, and it wasn't the person he thought it was.

It wasn't Gon. This boy, that had bumped into him had big green eyes and freckles on his face. He looked a lot scrawnier than his best friend.

To be honest, he looked a bit plain to Killua.

Compared to all of the other people with unique features, this boy didn't really stand out.

But he looked so enthusiastic. Maybe that was one of the similarities. He had a pen and a notebook in his hands and was talking with the old man beside him.

There was too much noise and commotion for Killua to eavesdrop on what they were talking about. Then a shadow flew over him.

The former assassin looked up and saw what looked to be a man made out of wood. He was wearing a blue uniform and didn't seem to have a mouth.

"You can do it, Kamui!" He heard some girls shout a distance away from him. They were certainly fangirls.

The fight could have ended earlier. At least Killua thought so. Maybe that tree-man stretched out the fight for publicity or something, Killua thought after seeing the supposed Villain tied up in defeat.

Killua put his hands in his short's pockets and simply walked away from the scene. Not short after, he caught a glimpse at the broccoli-haired boy giving a wide smile to the old man.

Oh how he wished Gon was there.

Killua hung up the phone after for hearing the dead beep for the fifth time. His phone didn't work. Well why should it? He was in a different dimension where they certainly have different phones. They looked quite boring in Killua's opinion.

"What do I do now?" He had tried everything. Calling, speaking to strangers asking where he could get to Whale Island or Kukuroo Mountain. All they responded with were weird glances and asking him if he was lost.

Well, of course he was lost! He was in a country he had never been in before. Experiencing normal things for these normal people.

Killua had nothing else to do, besides to find a way back to his own world. So he went to a local computer café and did some research.

Apparently, about every single person on this planet had superpowers, or as this world called them, Quirks.

Lame, Killua thought and kept gathering information.

To sum it up, Killua learned about Agencies, the law, Heroes and Villains. The number one Hero was someone known as All Might. He looked to have a strength type of Quirk, Killua picked up after watching a few videos on this guy.

And then there were the Schools. The School everyone who desired to be a Hero went to was U.A. High. One of the most prestigious Schools in the country.

School, Killua repeated the word in his head. He had never been to School. Not even private School. He had been thought everything he knew by a private teacher and his parents.

But Killua wasn't planning on going to School. Going to some School where he had to learn was probably on the bottom of the list of solutions on how he could get home.

However, he kept reading stuff about the stupid School. And something certainly caught his eye.

"Entrance Exam?" It reminded him of the Hunter Exam. Unbelievably easy. But maybe this Entrance Exam would be more difficult since it played by different rules.

What would be better to kill time, than to take a supposedly super-difficult Entrance Exam for fun?

"Ten months?" He had to wait ten months to be able to participate in the Entrance Exam.

The white/silver-haired boy took a deep breath in and kept thinking that his friends would be okay without him. Besides, he could continue to find a way back in the meantime.

The one thing Killua learned about being an assassin was to have patience. And wait for the target to arrive.

A/N: Hello fans of Hunter x Hunter and My Hero Academia, or just one of them. For context, Killua is 15 when the Entrance Exam begins. I'll admit that I like his assassin side, more than his Nen side so there will probably be more assassin moves than Nen. Don't want to show all the cards in his hands, right? Anyway, let me know what you think of the story so far! And if I should bring in some other characters from the Hunter x Hunter universe. No promises!
