What Happens Inside the Dungeon is a boundary-pushing fantasy series that reimagines the world of monster hunting through a lens of absurd, adult-oriented humor. The story begins with the death of the revered Swordmaster Hoss during his final battle against the Shell Dragon. However, his passing reveals a shocking secret: monster parts can be utilized for intense private pleasures. This revelation triggers a worldwide craze, turning the once-noble profession of monster hunting into a libidinous pursuit of 'spoils' that has completely reshaped society.
At the heart of this chaos is Cheong, the daughter of the late Swordmaster. While she possesses her father's superhuman strength and incredible combat prowess, she is also remarkably naive about the perverted world she now inhabits. Accompanied by the skilled assassin Chunja, Cheong dives into the dungeons to prove her worth and uncover the truth behind her father’s life. As she climbs the ranks, she discovers that her own lineage is far more complex than she ever imagined, granting her unique—and often embarrassing—ways to grow stronger through her own physical experiences.
Created by the popular artist Reva, this webtoon has gained a cult following for its striking contrast between top-tier action choreography and raunchy comedy. Despite its mature themes, the series is lauded for its surprisingly deep world-building, high-fidelity art style, and a cast of characters whose organic growth keeps readers invested. Whether you are looking for intense fantasy battles or side-splitting subversions of RPG tropes, this series offers a wild, unforgettable ride from start to finish.
