Hunter x Hunter Episode 139: Alluka x and x Something

Illumi explains to Hisoka that Alluka’s power has caused multiple deaths in the past and that the Zoldyck family spent a long time testing the rules behind it, including cases where requests led to the deaths of people close to the requester. He says that if Alluka’s requests are failed enough times, the price becomes deadly, and that the family has learned the danger can extend beyond the person making the wish to other people they care about.

The episode then shifts to Killua with Alluka, where he is focused on using her ability to help Gon while also protecting her from the family’s interference. At the same time, Illumi becomes increasingly intent on stopping Killua and seeks help from Hisoka, warning that Alluka’s power could put the family at risk.

The story also continues the Hunter Association election plot in parallel, with the Zodiacs still unable to settle on how to finish the election process. This keeps the episode split between the personal conflict surrounding Killua, Alluka, and Illumi, and the larger political stalemate at the Association.

In the second half, the episode focuses on the practical details of Alluka’s rules as Killua tests how to handle her requests safely. The information makes clear that her power can be used to help, but only if the conditions are obeyed, and the episode emphasizes Killua’s determination to work within those rules rather than let Illumi control the situation.
