Danny rarely got to decide what to do with his future. He got his power because his friends urged him to make a mistake, the career test laid out the future of an underpaid fast-food chain worker. But perhaps a new world could help him make a choice of his own and forge his own path.

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?

Basically what it sounds like,

Killua sighed, swinging his legs. I can't believe this is what my life's come to. He scowled down at his short stubby legs. "So, how old are you?" the black haired woman who was standing in front of him asked. It was embarrassing to answer. "Seven" He despised how high and squeaky his voice got, and how people kept crooning over him and looking at him like he was some kind of adorable kitten. However it was necessary for the mission. Bisky and another Nen user had worked together to reverse age him. Not just his appearance, his entire being. He was left with his fourteen year old brain, in his seven year old body.

Killua woke up in what he thought was a village. It looked to be far out in the country, and something almost immediately caught his eye when he sat up. It was skull. A bigass skull with horns and three eye sockets. "The fuck?" He didn't know if he should be scared, or just uneasy. The thing was long dead, but did more of them exist around here? And then he also realized. Where is Gon? Killua froze, then pushed his En out as far as he could. No no no no no no damn it! Where the hell is he? His teeth gritted together as he stood up, then he heard something. "Help!" Killua broke out of his worries and his eyes snapped in the direction of the voice.

Killua didn't know how he'd gotten into this situation, or how to get out. All he knew, was that in order to survive he had to kill the demon in front of him. He'd been turned into a demon a few weeks ago, feeding to get stronger. He was bound by the urge to obey a voice that spoke in his head sometimes, the voice of Muzan Kibutsuji. His body had gone through one shift, one that gave him a horn on the side of his head. It was the color of his skin, and about 5 inches long. Kill.

"Perhaps we can make a deal? I'm afraid I've already signed her up for the exam and it's too late to find another child." A catlike smirk went across Killua's face, getting a perfect idea. "How much money are you gonna cough up?" Killua's assignment didn't exactly have a due date, and as long as he got to gorge himself on as much sweets as possible and get to relax while 'doing his job' to him that was a win. "Well...How about five thousand dalc?" Killua hummed, then smirked. "Forty." Loid scoffed. "Ten." Killua took a step closer, placing his hands on his hips. "Twenty." Loid's eyes narrowed slightly. "Fifteen." "Deal."

Izuku Midoria was in class, it was a normal day. Then, came an announcement from his teacher. "Class 1-A, you will be meeting your parents in their youth today" Mr. Aizawa said. Midoria's eyes sparkled a little, and the rest of the class started chatting to one another. I finally get to meet my dad! "Deku!" Uraraka said excitedly, running up to his desk with bright eyes. "This is finally your chance to meet your dad!" He smiled eagerly, grabbing out a new notebook. "I was thinking the same thing Uraraka-san! I'll take as much notes as I can, maybe I could get a picture too" He said, almost giddy with excitement. "Sir, how is this possible?" Denki asked, raising a hand. Mr. Aizawa sighed. "Some...child with a magic pencil or something"

Killua had been a demon for four months. He had gone through a few shifts and he had a few new features. The most prominent was a horn that protruded from the right part of his forehead, it matched the color of his pale skin. The next was his tail, long and white. It had the appearance of a cat's. He also had a pair of fluffy white cat ears. The one thing he hated about his look was the markings on his face though. There were black cracklike patterns that littered it like scars or cracks in a worn heavily used pavement. His eyes were slitted feline like, and there were the same patterns on his arms and legs, this time in an electric blue. Killua's blood demon art allowed him to transform into a variety of snowy white colored animals. His favorites were a cat, wolf, owl, and a rabbit. He had to drink the blood of that specific animal within the last 24 hours for his blood demon art to work. Sometimes if he concentrated enough he could feel the traits of an animal he'd eaten while in his humanoid form. While in the form of an animal, he can only use a tenth of his strength. What Killua couldn't figure out, was why he knew certain things. He knew where all the vital points on a human were, how to bandage a wound, how to use a knife, how to extend his senses outwards, despite never having done them before.

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.
