The Succession War in Hunter x Hunter pits the 14 Princes of the Kakin Empire against one another in a ruthless battle for the throne. Behind these Princes stand the eight Queens, each vying for political power, survival, and the protection of their heirs. These Queens hail from various social strata, and their influence over the Succession War is as diverse as their backgrounds. Each given name is inspired by a number reflecting their corresponding rank (e.g. Swinko-Swinko = Cinco), further stripping them of their own identities, and fostering resentment and competition between them even before the games begin.
