Hunter x Hunter (en) follows a young boy named Gon Freecss who discovers his father, Ging, is a legendary Hunter—a licensed adventurer who pursues treasure, rare creatures, or forbidden secrets. Determined to find him, Gon takes the deadly Hunter Exam, where he befriends three other applicants: Kurapika, the last of his clan seeking revenge; Leorio, a pragmatic aspiring doctor; and Killua, an assassin fleeing his family. The story expands into larger arcs involving a high-stakes auction, a virtual reality game where players can die, and a brutal underworld conflict. Readers enjoy the series for its deep, complex characters, inventive power system (Nen) that rewards strategy over brute force, and the sharp tonal shifts from lighthearted adventure to dark, psychological tension.
