This story has been rewritten! _____ After many months of Gon and Killua being separated, a cloaked figure took Gon to a new world. Killua and Alluka wished themselves into a place far from their family. Killua and alluka ended up near the league of villains, while Gon was at the park. How will the two react to their new environment and how will they get back home? Read to find out! _____ Yes a bad description, but it'll get interesting! This fanfic is inspired by blue and orange by Hyped (on fanfiction.net highly recommend it), Two Worlds Apart by cartoonfan9 (also in fanfiction.com), Not Quit A Villain (but far from a hero) by FreeFacepalmSamples and many others. A fact before reading: Gon and Killua will be around 15 in this story.

Killua was awoken by a hand shaking him. He grumbled, turning the other way. "Fuck off Gon...." he mumbled. "Excuse me? Sir...?" Killua froze, then snapped upright wide awake. The girl who had been shaking his shoulder jumped back with an awkward laugh, rubbing the back of her head. "sorry..." how didn't I hear her? Or wake up? His eyes scanned over her face. Short brown hair, a kind smile, and slightly rose colored cheeks that seemed to be in a state of constant blush. "I'm Ochako Uraraka. Why....why were you sleeping in the middle of the sidewalk?"

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 😭

Killua and Gon find themselves in another universe without any idea on how to get back into their own world. They meet others, make new friends, but also new enemies. Will the both of them survive in a world that isn't their own, with superpowers very similar to nen? Oh yeah, and they're partially cats now. Before you read this story, I think it is important to know that english is NOT my first language, so please point out any mistakes so I can improve in the future!

It was a normal day for Gon and Killua who had just reunited a year after being separated. They were both 15 and living in an apartment in York New. Alluka had insisted on staying at Whale Island with aunt Mito. "Killua let's get that cat!" Gon had said, on their way to a café, running into an ally following a strange cat. "Don't just run off BAKA!" Killua yelled but nevertheless followed his idiotic friend. Little did they know that this was no ordinary cat, but a cat that would turn their whole world upside down; rather take them into another world. How will Killua and Gon cope in a world where killing isn't the norm and where being a 'hunter' meant nothing, but instead 'Pro heroes' are at the top of the food chain. And are Killua and Gon the only victims of this mysterious cat?

Killua couldn't move. He couldn't scream, couldn't run, he could only watch. Watch as Illumi stood over Gon, blood pooling around his body. G-Gon... Illumi turned to look over his shoulder for a second, those large black eyes that haunted his dreams stared back at him. "this'll teach you. You'll have no choice but to come back and become the heir Kil" His entire body went as cold as ice. No...No!...NO! Killua woke up with a start, tears streaming down his face and gasping for breath. "GON!" Killua blinked, then his brain registered the hard sidewalk beneath him. He sat up, looking around. He was in what he thought was a neighborhood, houses and roads as far as he could see. It was...a dream? He wiped his eyes, then bit his lip. Where am I?
