Dungeon Kurashi no Moto Yuusha

After defeating the Demon King, Blum Dilmond earned the title of hero—only to find himself relentlessly hunted by the very kingdom he had saved. Forced into a desperate bid for survival, he spent his days evading assassins sent to claim his life. Cornered and running out of options, Blum conceived an audacious plan: to seek refuge in the one place no human would dare follow him—the dungeon that once served as the Demon King’s domain. Without hesitation, he descended into its depths, expecting nothing but ruin. Instead, he encountered two highly unexpected figures. The first was the very mage who had aided him during his battle against the Demon King. The second was Irene, a former subordinate of the Demon King who now worked as a maid within the crumbling fortress. Recognizing that their interests aligned perfectly, the three formed an unlikely alliance. With the Demon King dead and the kingdom still hunting them, they resolved to personally restore the dilapidated dungeon. Working together with earnest determination, the former hero, the loyal mage, and the demon maid set out to transform the decaying labyrinth into a secure sanctuary where they could finally live in peace.
