Hunter Exam arc
When confronted by Gon about where Killua went, Illumi Zoldyck mentions the summit of Kukuroo Mountain as the home of the Zoldyck Family. Gon, Leorio, and Kurapika search online information pertaining to the mountain; its size and continental location as well as region are revealed. Upon arriving in the Dentora Region, the group takes the advice of a market stall owner to take a bus to the mountain. A tour guide of Lamentation Tours elaborates known information on the Zoldyck Family and elaborates on the periphery of their home. At the site of the Testing Gate, Gon, Leorio, and Kurapika stay behind much to the perplexion of the tour guide and tourists. They befriend the groundskeeper Zebro who allows them to train there for close to a couple of weeks so they could climb Kukuroo Mountain in order to rescue their friend Killua.
The group passes through the gate and is confronted by a young girl butler by the name of Canary. For the most part, she fends off Gon in a stoic fashion, however, as he becomes heavily bruised she begins to waver. This causes Killua's mother Kikyo (accompanied by her son Kalluto) to intervene. Initially, she lies claiming that Killua is unable to see them, however, due to the grandfather Zeno intervening on the matter, she returns home in a haste in an attempt to bar Killua from leaving home. Kikyo, however, fails to do so as Killua had a heart to heart conversation with his father Silva who allows him to leave and Kikyo chastises him over the fact.
Meanwhile Canary leads Gon's group to the butler quarters where they are greeted by Gotoh and his cohorts. Inside the quarters, Gon's injuries are tended to and, to pass the time, they play a coin game that quickly escalates to a point where their lives are on the line. They manage to win and are greeted by Killua and the group leaves the mountain.
