How to Build a Dungeon: Book of the Demon King

In How to Build a Dungeon: Book of the Demon King, a series from Seven Seas Entertainment that began in 2016, a failed adventurer is reborn as a demon lord with the power to create his own dungeon and command its monsters. This ongoing comic blends fantasy world-building with humorous, strategic dungeon management, as the protagonist navigates both the perils of his new role and the quirky inhabitants of his domain. The series is notable for its inventive take on the "isekai" genre, focusing on the logistics and politics of running a monster-filled lair rather than straightforward heroics.
