Killua stops trying to take the ball from Netero because his killer instincts are surfacing. Anita escapes her handlers and attacks Killua, who comes close to killing Anita, but lets her live because otherwise Gon would get mad at him. Gon is never able to get the ball, but makes Netero use his left leg and both hands once, and is satisfied.

The fourth stage of the Hunter Exam is a manhunt on Zevil Island. Each examinee must collect 6 points; their own number badge is worth 3, the number badge of their target is worth 3, and any other number badges are worth one point. Gon's target is Hisoka, and he practices catching birds with his fishing pole to prepare. He realizes he must attack Hisoka when Hisoka attacks his own target. Gon learns this by watching birds catch fish from the water.
