Ep. 140: Killua and Alluka depart with butler supervision while Leorio confronts Ging during the election.

Killua receives permission from his family to leave the Zoldyck estate accompanied by Alluka, who holds Threat 4 status. Several butlers, including Gotoh, Canary, Tsubone, and Amane, are assigned to supervise them and must return them home if Killua leaves Alluka’s side or if secrets are leaked. Alluka unexpectedly requests Tsubone’s pinky fingernail, which Tsubone provides before hiding to prevent further demands. In a separate event, Leorio confronts Ging regarding his failure to visit Gon at the hospital. This confrontation occurs during the fourth round of the Hunter Chairman Election, where Leorio punches Ging through his Nen ability after receiving instructions alongside Morel. The narrative continues within the 13th Hunter Chairman Election arc, specifically part 4 of 12.
