What is Dungeons / Gates?

In the dungeon/gate subgenre, rifts open into monster-filled labyrinths that threaten the modern world. "Hunters" or "players" — people who've awakened special abilities — dive in to clear them, growing stronger and richer with each raid.

It pairs naturally with the system/leveling trope: dungeons are where the hero grinds levels, finds rare gear, and climbs the rankings. Solo Leveling is the genre's flagship.
