The Greed Island Badlands (岩石地帯, Ganseki Chitai—lit. "Rock Zone") are a series of hills in Greed Island.[1] It is where Gon and Killua trained with their new master Biscuit.[2] They repeatedly dug through these hills using shovels until they reached Masadora, and then fought their way back against the many monsters[3] that inhabited the area.[1][2]
Abandoned Camps: Are the camps that Killua, Gon, and Biscuit find in the hills during their Nen training.
Caves: The caves or tunnels dug through the hills by Killua and Gon as part of their training. It becomes more difficult when they try to dig deeper, so they learn Shu and apply it to their shovels.
