Kyuu is participant #105 in the 287th Hunter Examination. Kyuu is one of the 24 Examinees to make it to the 4th phase of the Hunter Exam on Zevil Island. His badge is the designated target of Pokkle, who paralyzes him with one of his poisoned arrows then takes the badge. Seeing him lying helpless on the ground, Gon bandages him and moves him to a place where he can wait safely until the effects of the poison disappear. Kyuu appears again in this arc to take the 288th Hunter Examination only to fail, by being knocked out by Killua. (Source: Hunter x Hunter Wikia)
