S-Class Dungeon’s Mistress

Adelaide, a succubus, inherited a measly F-rank dungeon and a mountain of debt. To avoid the Demon King’s debt collectors—who threatened to chop off at least one of her arms—she had no choice but to manage the dungeon and pay off her debts. It seemed impossible, but… “Are you my master?” “No, I’m the master of this dungeon…” “Yes, then you are my master.” Upon arriving at the dungeon, she gained the perfect manager. “Don’t touch those insignificant beings, consume me.” The devil, the apex predator of the demon world, offered himself as nourishment. “I brought the prince’s head as an offering for you.” The legendary hero brought offerings she didn’t even ask for. Alright! Since things have turned out this way, the goal is S-rank!
