User blog:-Saryn-/Nen in Heaven's Arena

Ok so I've been confused about this for awhile, throughout the show they make it pretty clear that civilians do NOT know about nen, so why is it that it's ok for the 200th floor fighters to freely showcase their nen? how does it not leak into public knowlage through seeing these insane fights? So far I've only thought of two possible explanations

1: It could be that its simply accepted that some people have a strange power that allows them to do these insane things (this would explain how killua knew about dragon dive without having known about nen). I'm skeptical about this however because kastro taking hisoka's arm off with his bare hands is one thing but watching someone controll tops without touching them, or a double of a guy just randomly appear, or watching someone stab his opponent to death with playing cards without even touching them seems a bit too far fetched to me. (also b/c killua couldnt use nen when he had previously seen zeno he wouldnt have been able to see dragon dive even if zeno had demonstrated it because its a transmutation ability

2: it could be that people in the hunter x hunter universe see floor 200 similarly to how we see MMA (staged american fighting) the earlier floors are easier to enter for civilians so it is likely generaly accepted that the fights down there are real but because it's so rare for a civian to make it to floor 200 its possible that the spectators see it more as an elaboratly staged act, and the fighters as actors rather than a legit fight.

let me know what you think, or if you have an explanation thats better than mine. (i know someone probably does)
