Everything was going well. Killua, you, and Gon, after spending some time with Kite, with the whole Chimera Ant thing, decide to take a short vacation, returning to York Shin, to the Sky Coliseum, specifically. To see Wing, Sushi, Bisky, Kurapika, and other acquaintances. You are witnessing the beginning of the first battle, Sushi, now the floor boss, vs. another of them. Everything seems to be going well, until Netero is captured during a visit by the three of you by masters of "On," the counterpart of nen, limitless, which persists even after death...

Gon, Killua, and you run through the halls of the Colosseum, trying to get to the bottom of this, but the On masters' accomplices intercept you too often. You manage to camouflage yourself inside a weapons depot only allowed on the 200th floor and above. Gon sorts through the variety of weapons while you sit on the floor next to some crates, wondering how you'll get out of this.

"Hey." Killua suddenly interrupts your comfortable thoughts.

"You should choose a weapon. Maybe they'll block our nen or something."
