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

What is the one thing you want to do most in this world? For Gon, it's spending time with his no-longer-absentee father, Ging. This time is cut short when Gon inexplicably finds himself in the My Hero Academia universe. If only he knew his best friend Killua (and Alluka) had been brought there too. When Killua is forced to take up the opportunity to show his sister a whole new universe of adventure and freedom, he decides that maybe it won't be too bad. 'This will be good for both of us', he thinks. He couldn't be more wrong. In a world full of heroes and villains, Killua is stuck between the two. And with each passing day it's getting harder to hide Nanika's existence from the dangerous world they've entered. The two best friends will soon cross paths, and discover that their universe isn't the only one being drawn to the world of My Hero Academia. [I don't have a specific time for when the characters are removed from their universe and sent to MHA, just use your imagination. Gon has his Nen even though he lost it, use your imagination for how he got it back as well.] [In this story Gon & Killua are 14, and Alluka is 13. Please don't be mad if it's incorrect or if any of the characters are OOC] [Oh also I think I'm going to add other characters from other universes but I'm not sure who yet]
