Killua Zoldyck was wandering around after reluctantly dropping Alluka off at Gon's place, to "take a break from everything", as the green haired hunter says. Little did he know, that chain of events will soon be lead to his appearance at an unknown region, which turns out to be a different dimension where people use these "gifts" called "quirks". [ on hiatus ( >﹏< ) ]

Killua was a trained assassin, adept in the skill of a swift reaction time before his opponents could ever hope to harm him. But the one-time Killua meets back with Gon after two years of separation, someone manages to knock him off guard. Now trapped inside of a strange world, in a crazy hero-oriented city dubbed Musutafu, Killua must adapt to this universe to make his way back to the people he loves. But emotions can get muddy; morals and goals can skew. What can the ex-assassin do when he begins to become content with his new life? Note: I began writing this story when I was 14. I'm 16 now, and so because of this my writing style has greatly improved. If you find the beginning chapters cringe I'm so sorry 😭

The world is not black and white. It is not grey, nor is it anywhere close to monochrome. The world was made of rainbows. Beautiful, terrifying rainbows. Killua Zoldyck knew these things, even if he hadn't, at first. And yet, even as he knew these things, he still managed to see his life through the bleak eyes of one who knew only death and pain. Because Killua, before learning of colors, was taught to fade into- to become- the darkness. Then Gon had arrived, bringing with him a plethora of yellows and blues and green- so much green- and Killua lost sight of the darkness. For a moment, it receded into the background. But only for a moment. Killua didn't want to lose his memories of the colors, but he did wonder if things would have been easier if he'd just gone along with the life laid out before him. The fear of losing the colors was what made them painful in the first place, but Killua couldn't help it. Once he'd seen them, he could never forget, even as their absence reverberated through his soul. The rain was grey. Soft, and light, but grey. A different shade than the one he'd grown up with, but still, grey had always brought him so much suffering. Would it stop, if he stopped struggling against it? In any case, Killua's world had disappeared, in the rain, and when he'd opened his eyes, the rain was bluer than he remembered. Pellets creating a barrage instead of droplets that melted on his cheeks. For a while, he returned to the shadows. When he finally emerged, he heard whispers of heroes and villains, of vigilantes. Of quirks. Killua knew far too much for his age, yet at the same time, far too little. But one thing he did know was that he did not want glory, he did not want fame or money. Killua wanted the colors, the fun, the laughter. And he'd do anything to get it. Now, remember one thing: Killua Zoldyck is not a villain. But he is far from a hero. *This fanfiction is inspired by other works of the genre; see the first page

Killua slammed hard into the ground. he didn't know how he fell or where he was, but he knew that he was alone. "Fucking god" Killua stood up, then looked down. I look half dead. There were gashes all over him, his shirt was ripped and torn as well. Then he felt a bolt of pain, it wasn't visible but it hurt like hell. I can't remember what happened. "HEY YOU!" his eyes snapped up to see a police officer running down the alleyway he had fallen in. "yeah?" he said, turning. Then he pulled a gun out. "S-Stay right where you are!" Killua blinked, "what did I do?" the officer was obviously terrified by the way his hands were trembling. He pointed to the ground next to him and his eyes followed the hand. "HOLY SHIT!" he jumped a good few inches in the air at the three dead bodies that were lying on the ground. Not that dead bodies scared him, it was just unexpected. Killua crouched and inspected them, only to hear a faint breath coming from one of the children. The group was a small family it seemed, and he couldn't ignore the child. "the kid's not dead, if you hurry you can-" there was a gunshot and he dodged, then froze. His eyes slowly drifted over to where the kid was. Did he just, shoot her?
