The Heaven's Arena is a tower combat arena, the world's most popular battle site, where victorious fighters ascend to higher floors as part of its reward system. The fourth-tallest building in the world, Heaven's Arena stands 991 meters tall and has 251 floors. Inside, thousands of martial artists compete daily in order to test their skills and advance to higher floors. The annual spectator attendance is over 1 billion and the building is fully equipped with service facilities, including restaurants and shopping.

Competitors are allowed to fight and defeat their opponent using any means, but weapons are not allowed on the first 199 floors. One is given prize money for advancing on each of the 199 floors; after reaching the 100th floor, competitors get their own private room. This place was perfect for training and earning money.

First to 50th floors, would reward money enough for a drink, but with showing strong fighting prowess, one can be sent to the 50th level directly.

I started to wait in a long queue for applying to fight in the arena. There were too many people wanted to fight for money, giving this arena doesn't look for any requirement, the people wanted to join was so high. I could earn money with my Hunter Licence, but I didn't want to use too much, and I was told to come here anyway. My main aim wasn't money but learning Nen.

After a few hours, it was finally my turn. I filled in a form for my registration. I was given number 1777 and told to wait in the spectator area. I was going to be called when it was my time to fight. There were too many fights going on at the same time. This was the lowest level of the arena, and only spectators were applicants themselves. After some time, I was called to fight. I went to the arena, and my opponent was already there.

He was 3 meters long, black man. He was big and muscle buffed. He looked at me with a smirk and said, "You little one, you better quit before I make force you to, or you will go to your mother in a shape even she could not recognize you." I get the tough guy act, but what the hell is the mother part? Why people use that phrase that much, indicating visiting a mother is a bad thing. I may be oversensitive on this matter, because I never had one, but it seems just wrong.

"My mother left me in the jungle for wolves to eat," I said and appeared in front of him in a moment. I punched him in the face, and he flew all the way to the spectator area. For some reason, Crow told me to win my fights with a single strike if it is possible. So, I did as he told. The referee declared my win and told me to go to the fiftieth floor.

Up to the 200th floor, the building is divided into twenty 10-floor parts. For example, a fighter who wins on the 40th floor advances to the 50th, and one who loses on the same level regresses to the 30th: a 10-story scale. My aim was to move to the 200th floor with a single punch. Starting from the 50th floor, all matches would be described by speakers, and spectators would bet on the fights.

When I reached to the spectator area on the 50th floor, it was almost my time to fight again. One had to apply for a fight if they want to. On a big screen, my picture taken in my first fight and the same for my opponent was displayed. Speaker told about the victory we had in our previous fight.

"Lord Hitomi won with a single strike, vanishing before everyone's eyes. He is fast! He is strong! Will he be the victor in this fight? Or his opponent. Lord Tulala, he won against his opponent after an even fight. But his opponent wasn't any weaker. It was just even matched fight. And afteeerrr this breathtaking fight, Lord Tuala won against his opponent and now will fight against Lord Hitomi!

We might not see the Lord Hitomi's real power, but in this fight, I believe he has to use more than a one -"

While the speaker was speaking, I went to the ring and waited for my opponent. When my opponent came to the ring as well, after the referee gave us the clear signal, I just used the same tactic to send my opponent to out of the ring with one punch, before speaker even finished her words.

"Um, Lord Hitomi won once again. And used one punch. I can't believe my eyes, we have a new rising star in our Heaven's Arena." Speaker got over her shock quickly and started to introduced me more. I started to go to the 60th floor.

All the way to the 100th floor, I finished off every opponent with a single punch. Crow told me, it would be different after 100th floor, but it was all the same. I arrived on the 200th floor in the single day. It was so easy. I was expecting some hard fight, maybe some Nen trainee but not a single Nen user appeared so far.

After I arrived on the 200th floor, I started to feel people's Ren. The there Ren especially was intimidating. I already heard from Crow that these three cripple were once like me, arrived on the 200th, but they didn't know how to use Nen. Thus they were all crippled. As soon as I went to the registration office on the 200th floor, those three came to me. They wanted to crush newbies because they were weakest on the 200th floor.

After 200th, one wouldn't earn money from the fight but would fight for the fame. I wanted to be floor master before leaving this place, but floor masters all had their special Nen powers, some even more than one. To challenge a floor master one must have 10 wins. But if one has 4 losses, they would eliminate from the 200th floors, and has to start over.

As I was registering for three consecutive days for fighting each of the three, Hisoka arrived with intimidating Aura. She looked at me with the same orgasmic expression and said, "I will fight with you, for your 10th win. Do not disappoint me." It was better to agree to this crazy woman because the alternative was hiding from her every second. After a match, I had 90 days for the next match anyway. I could create my Nen until then.
