A message of hostage exchange sends Welfin on the field. One moment he encounters Menthuthuyoupi, and the next, Shaiapouf finds Youpi lifeless. When he returns to the King, Meruem demands Shaiapouf's secrets. On their way, Shaiapouf unsuspectingly coughs out blood, just like how blood trickled from the King and Menthuthuyoupi.

Killua is allowed by his family to leave the Zoldick estate with his sister, but only under supervision of several butlers with orders to bring them home if he ever leaves Alluka's side or allows any of their secrets to be leaked. Meanwhile, Leorio appears and confronts Ging, asking him why he had not ever paid a visit to Gon at the hospital yet.

Gon apologizes to Kite for not being strong enough to save him. Kite tells him they'll always be friends and that he should go get to know his dad. Gon returns to the Election Hall only to find a note that Ging has gone to the World Tree. Gon, Killua, and Alluka journey to the World Tree where Killua reveals Alluka's powers to Gon. Killua vows to protect his sister and says farewell to Gon, promising they'll meet again. Gon in turn promises to introduce Killua to Ging when they meet again.
