❝𝐊𝐢𝐥𝐥𝐮𝐚; 𝐓𝐡𝐞 𝐀𝐬𝐬𝐚𝐬𝐬𝐢𝐧 𝐊𝐢𝐝❞ Just Killua found himself beside the blue sea. ____________________________________________________ Killua in One Piece. -(Random Update.) -I do not own One Piece Anime and the Hunter x Hunter's Killua Zoldyck.

Killua finds himself in a unfamiliar world, taken hostage and held in an illegal quirk fighting arena. But what happens when he finds himself in such a sticky situation? and realizes he can't get home on his own just yet. One thing leads to another, will you join him on his journey? A journey of heroes and villains, vigilantes and killers? ⚠ 1: Killua cares about people that aren't just Gon. ⚠ 2: Killua is not overpowered as soon as he arrives!!! It takes time to get used to quirks. I'll admit that I do update slowly, but please keep in mind I'm a student and don't have an abundance of time on my hands. I do not own BNHA or HXH nor the characters in them! Art shown is not owned by me and can either be found off google or Pinterest! Find someplace comfy to relax and enjoy reading :)

When two new transfer students arrive at Class 3-E, everyone has mixed opinions on them. Everything seemed to be normal but soon students begin disappearing.

Killua was just minding his own damn business when he was suddenly he sensed something that made his blood run cold. It was Illumi's bloodlust. He recognized it instantly and let out a gasp. Alluka! She was no more than ten meters away, completely oblivious. The fuck do I do- suddenly the air went cold and he heard a whoosh. And then he was falling, coming hard down on the ground which was alarmingly only a few meters away. "WHAT THE FU-" and then he was on a nearby rooftop, completely on his feet, and unharmed. He blinked for a few seconds. "the fuck just happened?" he glanced around, then realized with panic that Alluka wasn't there. "Alluka!" he ran to the edge of the building, looking frantically down below. She's not there... she's not fucking there! Where is she? He started to hyperventilate, his hands going to his head. Illumi was there! What if he got her? Tears stung the corners of his eyes and his legs buckled beneath him, falling to his knees. "No... I can't- Alluka..." he choked out, and then he instinctively snatched a knife out of the air as it was flying at him, still hyperventilating.

It is around thirty years after the Battle of Hogwarts, and Hermione and Luna have completed work on a project they'd been working on for the new Magical Science department in the Ministry of Magic -- a portal to another world. Excited for the chance to have one more journey together, the Golden Trio become the first people to ever step foot through this portal. However, what crazy adventures await them in a world of death being flippantly written off, Nen, and a couple of kids who are definitely (almost probably) some sort of superhuman?

Watching Assasination Classroom got me thinking, if teenagers are learning how to become assassins, why not add a teenager who's already an assasin 😋 and his cute, green friend 🎣, not baby Yoda people. Also all the characters and cover photo are not mine, neither will/do I ever claim them to be.

"Big Brother," She called out warily staring at the creature beneath them," What's going on?" she asked. ................... I do not own any of the characters . The characters from Attack On Titan and HunterXHunter are not mine. This is a cross over story so the only thing I own is the plot.

He had been the pale boys first friend, the one to show the ex-assassin that he was more than the killer his parents trained him to be. But also, Gon was the one who told Killua that he was unable to feel basic sentiment or empathy. "Since it means nothing to you." It felt like Gon was staring into the depths of his soul, unraveling Killua bit by bit with his earnest gaze. It was unnerving how beautiful the amber eyed boy was. Frightening. Karma Akabane was a fighter. He coveted violence, worshipped it as though it were a God. Or maybe violence worshipped him. It was a tough call. Nagisa observed the two teens with a slight sense of awe. Assassins? That young? Granted, Nagisa himself was only 17, probably the same age as the proctors. The two males certainly seemed strong, but then, so was everyone here. So this is the Hunter Exam huh? Okay then, no holding back his blood-lust. Alluka Zoldyck was going to be a Hunter. Like her big brother. Like Gon. She trained viciously for three years, and now it was time. She had become strong, strong enough to care for herself and the sooner she could prove that to him, the sooner she could live her life without fear. And the sooner Killua could stop using her as a buffer to stay away from Gon.

What is this abomination I have created? If you like it, YAY! If you don't, sorry!

Just as Killua was about to let Gon go on his way to go find his dad, a portal opened below him. "GON!" he yelled, diving after him without a moment's hesitation. Suddenly they were falling out of the sky and the ground was coming up quick. Very quick. "KILLUA!" Killua grabbed Gon and twisted so his back was aimed for the ground, preparing for impact. He knew it was going to hurt, but he would rather take the pain himself rather than having to share it with his best friend. "hold on tight! It's gonna be a rough landing!" Killua clenched his teeth and braced himself, before slamming into the ground so hard it knocked the breath out of him. Oh god- his entire body hurt like crazy, especially his back and shoulders. "Killua! Killua! Don't die!" Gon started to sob, shaking his shoulder. " I'm not dead idiot" he decided to sit up, opening his eyes to see they were in what looked like an alleyway? "hey Gon, where the hell are we?" 6/18/2021: number 10 in the tag Gonkillu
