The Skyscraper Battle Arena is kind of similar to Trick Tower. The only different is that you moved from the bottom to the top where the Battle Olympia is held. It is about 2900 ft from the sea. It has 200 floors. Each win will move you up to higher floor.
You have to register at the reception put all your fighting information. The first round to is test round.they will see how good you are and which floor you should move up to. Killua first came here when he was 6 and he had moved up to 199th floor . Gon was moved to 50th floor since the first round and so as Sushi. This time , Killua is moved to 180th floor since the first round but he rejected it. Killua asked to be moved to 50th floor with Gon.The following rounds as you move up to higher floor, the fight money and the living quality will be higher too. At 200th floor, the rooms are make you feel like living in the highest condominium but not to Killua,beacause his house is located at 3000 ft. All the fighters on this floor uses "Nen" and has great skills .If a new comer didn't know this, they'll receive the "Welcome Freshies" which will end up with body injuries. Even though Gon was taught about Nen by Wing, he had bodies fractures all over after a match with Kid.
During the 90 days after the floor registration, fighter can fight any time with in this period. If the fighter wouldn't fight in time, they have to go back and start from the first floor. But if you sign in the date of the match, and didn't show up, it will just be counted as a Lost. Hisoka did this two times. If a fighter wins up to 10 times, they'll have the chance to fight with the Floor Master who is the best of that floor. The winner will be able to attend the Battle Olympia which is held once in every 2 years on the topmost floor.
Castoro said he will wait for Killua at the Battle Olympia. Gon's goal is to beat Hisoka. Killua's goal is just collect money. Nobody knows what will happen next except Yoshihiro Togashi.
