Synopsis
One ability. One summon each day. A complete dungeon to develop from scratch. Freya finds herself in a mysterious world with a system in her vision and a dungeon under her control, possessing a singular power: [ Unique Skill Gacha ][ Summon anything that exists, from Rank G to Rank SSS — once every twenty-four hours. ]It might give her something worthless. It might give her a deity. Her initial summon results in an SSS. [ Aria Demonic Maid of Knowledge — Rank SSS ]The ideal maid: loyal, intelligent, eager to fulfill her mistress's every desire. However, she has one flaw. She’s a yandere, and she won't allow anything to come between them. Nothing and no one. Now the real effort begins. Dig, construct, summon, and upgrade every aspect of her realm, tier by tier, transforming bare rock into a dungeon that deserves the title. Yet, Freya is not the sole Earthling in this competition. Other Dungeon Lords are cultivating their own realms, an entire world is marking them as adversaries, and outside the walls, heroes are sharpening their weapons, anticipating a single opportunity: to break in and reduce it all to ashes. Luck gifted her an SSS on the very first summon. She’s going to require it.
