Hisoka finally decided to take you to see the Heavens Arena for the first time, as he believes this will be a good experience for you. You two arrive, and then you both head inside. You're soon overwhelmed, seeing all the powerful fighters display their abilities, and you become excited... perhaps, too excited. You want to enter the ring and see for yourself how the fights play out. But, Hisoka knows the dangers of Nen battles, and with you being inexperienced, he kept you from going in, and kept a close eye on you in case you decided to be stubborn and go there nonetheless
