Chapter 5: Heavens Arena

Kai and Killua accompanied Gon to the Heavens Arena, a skyscraper where fighters competed for money and fame. They had decided to go there after leaving the Zoldyck mansion, following Gon's suggestion. Gon wanted to go there to earn money to buy a video game console that he had promised to his friend, Zepile. He also wanted to go there to improve his fighting skills and learn more about nen. Kai and Killua agreed to go with him, as they also wanted to do the same things.

They arrived at the Heavens Arena, which was located in a city called Heavens City. They were amazed by the size and the design of the building, which was 251 floors high and had a circular shape. They entered the building and registered as fighters, receiving their ID cards and their room keys. They learned that they had to climb the floors by winning fights, and that they would earn money and points for each win. They also learned that they could use their points to buy items or services in the arena, such as food, clothes, or training.

They stepped into the arena, a massive tower that loomed over the city. They had one goal: to reach the top and claim the ultimate prize. But they knew it wouldn't be easy. Each floor had its own challenges and dangers, and the opponents grew stronger and more skilled as they ascended. They began from the bottom, the 1st floor, where the fights were nothing more than warm-ups. They relied on their raw physical power and agility to overpower their foes, who were either inexperienced or overconfident. They breezed through every match without breaking a sweat or suffering a scratch. They raked in money and points with ease and efficiency.

They arrived at the midpoint of their journey, the 50th floor, where the fights demanded their utmost effort and intelligence. They utilized their honed martial arts skills, such as karate, judo, and taekwondo, and techniques, such as kicks, punches, and throws, to defeat their formidable opponents, who were either veterans with years of experience or prodigies with natural talent.

They managed to win most of their matches with some hardship or injury, such as bruises, cuts, and sprains. They earned money and points at a moderate pace and level.

They climbed up to the 100th floor, where the fights became even harder and more complex. They used their nen skills and abilities to defeat their opponents, who were mostly nen users or masters. They won some of their fights with a lot of difficulty or injury. They earned money and points rarely and sparingly.

They also learned more about nen, the mysterious energy that allowed them to enhance their abilities and perform various techniques. They learned that nen was divided into six types: enhancement, emission, transmutation, manipulation, conjuration, and specialization.

They learned that each type had its own characteristics, advantages, and disadvantages. They learned that each person had a natural affinity for one type, but could also use other types with varying degrees of proficiency.

They learned that they could use nen in four basic ways: ten, zetsu, ren, and hatsu. Ten was the ability to create a shroud of nen around one's body, protecting it from harm and hiding it from detection.

Zetsu was the ability to stop the flow of nen in one's body, making it invisible and undetectable by others. Ren was the ability to increase the amount of nen in one's body, enhancing one's physical capabilities and aura output.

Hatsu was the ability to release one's nen in a specific way, creating various effects and phenomena.

They learned that they could also use nen in advanced ways: gyo, in, en, shu, ko, ken, ryu, and hatsu techniques. Gyo was the ability to focus one's nen on a specific part of one's body or object, increasing its power or sensitivity.

In was the ability to conceal one's nen from others by using zetsu on it, making it invisible but still effective. En was the ability to extend one's nen around one's body in a spherical shape, sensing everything within its range.

Shu was the ability to apply one's nen on an object or weapon, enhancing its durability or sharpness. Ko was the ability to concentrate all of one's nen on a specific part of one's body or object, creating a powerful attack or defense.

Ken was the ability to distribute one's nen evenly around one's body, creating a balanced defense against attacks from any direction. Ryu was the ability to adjust the amount of nen on different parts of one's body or object according to the situation, creating a flexible offense or defense.

Hatsu techniques were the unique abilities that each person developed based on their nen type and personality.

They learned all these things from Wing, a nen teacher who agreed to train them and teach them the basics of nen.

They encountered him on the 50th floor, where he was observing their fights with keen interest and curiosity. He was a tall and muscular man, with short black hair and piercing green eyes. He wore a dark green jacket and pants, and a silver necklace with a strange pendant. He had an aura of confidence and authority, and he seemed to know more than he let on.

He approached them after their last fight, which they barely won against a pair of twins who used strange powers. He smiled and introduced himself as a hunter and a nen master, someone who could manipulate his life energy in various ways.

He offered to teach them nen, saying that they had a lot of potential and talent. He praised their martial arts skills and techniques, but he also warned them that they would face more nen users and dangers as they climbed higher. He said that he could teach them the basics of nen in a short time, but that they would have to follow his rules and instructions.

"Hello, I'm Wing. I'm a hunter and a nen master. I've been watching your fights, and I must say, you two are impressive. You have great physical abilities and martial arts skills. But you also have something else, something rare and precious. You have potential. Potential to become nen users."

"Actually we already know nen, we just don't use them during these fights because they are easy" said Killua.

"Well I will still explain Nen to you guys, Nen is the ability to use your life energy, or aura, to enhance your body and mind, and to create various effects. It's the secret power of hunters, and of many other people in this world. It's also the power that those twins used against you. They were manipulating their aura to create illusions and attacks. They were weak nen users, but still dangerous enough to give you trouble."

"So you're saying that there are more people like them on the higher floors?" Leorio asked a little worried.

"Yes, there are. And they are much stronger and more skilled than those twins. If you want to survive and reach the top, you need to learn nen. And I can teach you besides the basics."

"Why would you do that? What's in it for you?" Kurapika asked, suspiciously.

"I'm doing this because I'm curious about you guys. You have a lot of talent, but you also have a lot of ignorance. You don't know anything the true nature of this tower. You're like lambs walking into a lion's den. I want to see if you can become lions yourselves."

"And what are your rules and instructions?" Kai asked, curiously.

"My rules are simple. First, you have to trust me completely. Second, you have to do everything I say without question or hesitation. Third, you have to be ready for anything. Nen is a dangerous and powerful force that can change your life for better or worse. Learning nen is not easy or safe. It requires courage and discipline. Are you willing to take the risk?" Wing asked, looking at them with a serious expression.

They looked at each other, unsure what to do. They felt both fear and excitement at the prospect of learning nen. They knew it was a rare opportunity, but also a risky one. They wondered if they could trust Wing, or if he had ulterior motives.

They hesitated for a moment, then nodded.

"Alright then," Wing said, smiling again. "Let's begin."

They followed him to his room, where he gave them a brief explanation of nen and its types.

Wing gave them a test to determine their nen types, using a simple but effective method. He took out a glass of water and a leaf from his jacket, and placed them on a table.

He asked them to sit across from him and place their hands over the glass. He told them to focus their aura on the leaf, which was floating on the water. He said that depending on what happened to the leaf, they would know their nen type.

"Nen types are the categories of nen abilities, based on how you use your aura. There are six nen types: enhancer, emitter, transmuter, conjurer, manipulator, and specialist. Each nen type has its own strengths and weaknesses, and its own affinity with other nen types. Knowing your nen type is important, as it will help you develop your nen abilities and techniques."

He pointed at the glass and the leaf.

"This is a simple test to determine your nen type. All you have to do is place your hands over the glass and focus your aura on the leaf. Don't touch the glass or the water, just use your aura. Depending on what happens to the leaf, you will know your nen type."

He explained the possible outcomes.

"If the leaf moves away from you, you are an emitter. Emitters can project their aura away from their bodies, and use it to create various effects at a distance. If the leaf moves towards you, you are an enhancer.

Enhancers can strengthen their aura and use it to boost their physical abilities and objects. If the leaf changes shape or color, you are a transmuter.

Transmuters can change the properties of their aura, such as shape, color, texture, or temperature. If the leaf disappears or turns into something else, you are a conjurer.

Conjurers can create objects or substances out of their aura, or make them disappear. If the leaf moves according to your will, you are a manipulator.

Manipulators can control objects or living beings with their aura. And if nothing happens to the leaf, or something unexpected happens, you are a specialist.

Specialists have unique and rare abilities that don't fit into any of the other categories."

He looked at them and smiled.

"Ready? Then let's begin."

They did as he asked, and saw different results.

Kai's leaf sank to the bottom of the glass, indicating that he was an enhancer. Enhancers were able to use their nen to increase the natural abilities of themselves or objects. They were simple and determined, but also stubborn and impulsive.

Killua's leaf changed its shape and color, indicating that he was a transmuter. Transmuters were able to use their nen to change the properties of their aura or objects. They were whimsical and versatile, but also deceptive and unpredictable.

Gon's leaf emitted a small spark, indicating that he was an emitter. Emitters were able to use their nen to project their aura or objects away from themselves. They were emotional and passionate, but also impatient and reckless.

Kurapika's leaf turned into a chain, indicating that he was a conjurer. Conjurers were able to use their nen to create objects or substances out of thin air. They were rational and meticulous, but also detached and obsessive.

Leorio's leaf moved slightly, indicating that he was a manipulator. Manipulators were able to use their nen to control the movements or actions of themselves or objects. They were logical and practical, but also stubborn and selfish.

Wing was impressed by their results, saying that they had rare and powerful nen types. He also said that they had strong and compatible personalities, which would help them develop their nen abilities. He said that he would teach them how to use nen in four basic ways: ten, zetsu, ren, and hatsu.

He started with ten, saying that it was the most basic and essential way of using nen. He said that ten was the ability to create a shroud of nen around one's body, protecting it from harm and hiding it from detection. He said that ten was useful for defense and stealth, as it could prevent physical damage and aura sensing. He said that ten was also important for maintaining one's health and vitality, as it could prevent aura leakage and aging.

He demonstrated ten by creating a thin layer of aura around his body, which glowed faintly in the dark. He asked them to do the same, saying that they had to focus their mind and will on their aura. He said that it might take some time and practice for them to master ten, but that they had to do it before moving on to the next step.

They tried to do ten, following his instructions. They closed their eyes and concentrated on their aura, feeling it flow through their bodies. They tried to control it and shape it into a shroud around themselves.

They succeeded after some attempts, creating their own shrouds of aura. They opened their eyes and saw each other glowing in different colors.

Kai's aura was red, reflecting his fiery personality and his enhancement type.

Killua's aura was blue, reflecting his cool personality and his transmutation type.

Gon's aura was green, reflecting his lively personality and his emission type.

Kurapika's aura was yellow, reflecting his bright personality and his conjuration type.

Leorio's aura was orange, reflecting his warm personality and his manipulation type.

Wing praised them for their success, saying that they had learned ten faster than he expected. He also said that they had beautiful colors for their aura, which showed their individuality and harmony. He said that they had completed the first step of learning nen, but that they still had a long way to go.

He continued with zetsu, saying that it was the second way of using nen. He said that zetsu was the ability to stop the flow of nen in one's body, making it invisible and undetectable by others. He said that zetsu was useful for stealth and evasion, as it could hide one's presence and aura. He said that zetsu was also important for conserving one's energy and stamina, as it could reduce one's aura consumption and fatigue.

He demonstrated zetsu by stopping his aura flow and disappearing from their sight and senses. He asked them to do the same, saying that they had to relax their mind and body and let go of their aura. He said that it might take some time and practice for them to master zetsu, but that they had to do it before moving on to the next step.

They tried to do zetsu, following his instructions. They opened their eyes and looked at their bodies, feeling them become lighter and colder. They tried to release their aura and vanish from each other's view and awareness.

They succeeded after some attempts, stopping their aura flow and becoming invisible. They closed their eyes and listened to each other's breathing, which was the only thing they could hear.

Wing praised them for their success, saying that they had learned zetsu faster than he expected. He also said that they had excellent control over their aura, which showed their talent and skill. He said that they had completed the second step of learning nen, but that they still had a long way to go.

He continued with ren, saying that it was the third way of using nen. He said that ren was the ability to increase the amount of nen in one's body, enhancing one's physical capabilities and aura output. He said that ren was useful for offense and intimidation, as it could increase one's strength and speed and create a powerful aura pressure. He said that ren was also important for expanding one's potential and limits, as it could increase one's aura capacity and endurance.

He demonstrated ren by increasing his aura flow and reappearing in front of them. He asked them to do the same, saying that they had to tense their mind and body and push their aura outwards. He said that it might take some time and practice for them to master ren, but that they had to do it before moving on to the next step.

They tried to do ren, following his instructions. They closed their eyes and felt their bodies become heavier and hotter. They tried to increase their aura and reappear in front of each other.

They succeeded after some attempts, increasing their aura flow and becoming visible again. They opened their eyes and saw each other glowing brighter and stronger.

Wing praised them for their success, saying that they had learned ren faster than he expected. He also said that they had impressive amounts of aura, which showed their power and potential. He said that they had completed the third step of learning nen, but that they still had a long way to go.

He continued with hatsu, saying that it was the fourth and final way of using nen. He said that hatsu was the ability to release one's nen in a specific way, creating various effects and phenomena. He said that hatsu was useful for creativity and diversity, as it could allow one to express one's individuality and style. He said that hatsu was also important for mastering one's nen type and abilities, as it could allow one to develop one's unique skills and techniques.

"Hatsu is the culmination of your nen training. It is the way you manifest your nen into reality, creating your own personal nen abilities. Hatsu is what makes nen fun and exciting, as it allows you to explore your potential and express your personality. Hatsu is also what makes nen challenging and rewarding, as it requires you to refine your skills and techniques.

Your hatsu will depend on your nen type, your personality, your preferences, your goals, and many other factors. There is no limit to what you can create with hatsu, as long as you follow some basic principles and rules. Hatsu is the most complex and difficult aspect of nen, but also the most rewarding and satisfying. Hatsu is the ultimate expression of your nen."

He demonstrated hatsu by releasing his nen in different ways, creating different effects and phenomena. He showed them his enhancement hatsu, which allowed him to heal his wounds faster. He showed them his emission hatsu, which allowed him to fire his aura as projectiles. He showed them his transmutation hatsu, which allowed him to change his aura into fire or water. He showed them his manipulation hatsu, which allowed him to control objects or animals with his aura. He showed them his conjuration hatsu, which allowed him to create objects or substances out of thin air. He showed them his specialization hatsu, which allowed him to copy other people's hatsu techniques.

He asked them to do the same, saying that they had to use their imagination and will to shape their aura into something else. He said that it might take some time and practice for them to master hatsu, but that they had to do it before moving on to the next level.

They tried to do hatsu, following his instructions. They focused their mind and will on their aura, imagining it as something else. They tried to release their aura in a specific way, creating different effects and phenomena.

They succeeded after some attempts, releasing their aura in different ways. They showed each other their hatsu techniques, which were based on their nen types and personalities.

Kai showed them his Dragon Fist, which allowed him to create a dragon-shaped aura around his fist and unleash a powerful punch. He said that it was his enhancement hatsu, which enhanced his strength and speed. He also said that it was inspired by his love for dragons and martial arts.

Killua showed them his Thunderbolt, which allowed him to generate and manipulate electricity with his nen and shock his opponents. He said that it was his transmutation hatsu, which changed his aura into electricity. He also said that it was inspired by his experience with torture and assassination.

Gon showed them his Jajanken, which allowed him to charge his nen into his fist and release it in three different ways: rock, paper, or scissors. He said that it was his emission hatsu, which projected his aura away from himself. He also said that it was inspired by his favorite game and his adventurous spirit.

Kurapika showed them his Chain Jail, which allowed him to conjure five chains from his fingers and use them for various purposes. He said that it was his conjuration hatsu, which created objects out of thin air. He also said that it was inspired by his clan's tradition and his quest for revenge.

Leorio showed them his Warp Punch, which allowed him to emit his nen through a portal and punch someone from a distance. He said that it was his manipulation hatsu, which controlled the movements of his nen. He also said that it was inspired by his medical knowledge and his practical sense.

Wing praised them for their success, saying that they had learned hatsu faster than he expected. He also said that they had amazing hatsu techniques, which showed their creativity and diversity. He said that they had completed the fourth and final step of learning nen, but that they still had a lot to learn.

He said that they had reached the 100th floor of the Heavens Arena, where they would face more challenges and dangers. He said that they would have to face more nen users and masters, who would use their nen in advanced ways: gyo, in, en, shu, ko, ken, ryu, and hatsu techniques. He said that they would have to learn these advanced ways of using nen, as well as develop their own hatsu techniques further.

He said that he would teach them these advanced ways of using nen, as well as help them develop their own hatsu techniques further. He said that he would train them and teach them until they reached the 200th floor of the Heavens Arena, where they would face the ultimate challenge and danger: the Floor Masters.

He said that the Floor Masters were the strongest fighters in the Heavens Arena, who had reached the top floor and claimed a room there. He said that they were all nen masters, who had mastered their nen types and abilities. He said that they were all formidable opponents, who had defeated countless challengers and defended their rooms.

He said that if they wanted to reach the top floor and become Floor Masters themselves, they would have to challenge and defeat one of them. He said that it would be the hardest fight of their lives, but also the most rewarding one. He said that it would be the ultimate test of their skills and abilities, but also the ultimate expression of their individuality and style.

He asked them if they were ready for this challenge, if they were ready to climb higher and higher in the Heavens Arena.

They looked at each other and nodded.

They were ready.

They enrolled in the arena and began to climb the floors, facing stronger opponents as they went up.

They also learned more about nen, the mysterious energy that allowed them to enhance their abilities and perform various techniques.

As they ascend the towering structure of the arena, they encounter Hisoka, the sinister magician who has a perverse obsession with Kai and Gon. He grins wickedly as he reveals that he is also participating in the arena battles, seeking out strong opponents to satisfy his bloodlust.

Kai feels a wave of rage and bitterness wash over him as he sees Hisoka, who tormented him during the exam and nearly ended his life. He glares at Hisoka and says, "You! I've been waiting for this moment. I challenge you to a fight on the 200th floor. I'm going to make you pay for what you did to me."

Hisoka chuckles and says, "Oh, how delightful. You've grown so much since we last met. I'm curious to see how much you can entertain me. Very well, I accept your challenge. But don't disappoint me, or I'll kill you without mercy."

He fights with all his might against Hisoka, using his speed, agility and intelligence to dodge and counter his attacks. He dashes, leaps and rolls, avoiding Hisoka's cards that fly like blades. He strikes back with his fists and feet, landing a few hits on Hisoka's face and chest, drawing blood and earning his respect. However, he is ultimately outmatched by Hisoka's superior experience and mastery of nen, the mysterious energy that enhances one's abilities.

Hisoka uses his nen to manipulate his cards and bungee gum, creating deadly traps and weapons that Kai can't avoid. He wraps his bungee gum around Kai's limbs, pulling him towards his cards. He throws his cards with such force that they pierce through Kai's flesh and bones. He smiles sadistically as he watches Kai fall to the ground, bleeding and broken.

He walks over to Kai and says, "You did well, for a novice. But you're still no match for me. You need to learn more about nen, and how to use it effectively. Maybe then you'll be able to entertain me more." He kicks Kai in the face, knocking him unconscious. He leaves the arena, satisfied with his victory.

He suffers a devastating defeat at the hands of Hisoka, who spares his life but taunts him for his weakness. He lies on the ground, battered and bruised, as Hisoka laughs at him.

He vows to improve his skills and face Hisoka again in the future, determined to overcome his nemesis and surpass his limits. He clenches his fists, feeling a fire burning in his heart. He swears to himself that he will not give up, and that he will make Hisoka pay for his humiliation. He looks up at the sky, hoping that Gon is watching him.

He whispers, "Gon, I'm sorry. I failed you. But I promise, I'll get stronger. I'll catch up to you. And I'll defeat Hisoka. Just wait for me." He closes his eyes, hoping to see Gon's smile again.
