That Time I Reincarnated as a Dungeon Core

What happens when death isn't the end, but a beginning-deep underground?

In a world where dungeons are feared, coveted, and hunted, one soul awakens... not as a warrior, but as a Dungeon Core-a crystal heart pulsing with mana, buried beneath the earth with no memory of its past life.

Armed with the mysterious ability to name and evolve natural creatures into humanoid guardians, the newly reborn Core begins building more than just traps and tunnels-it begins forging a kingdom.

From a lonely slime turned sword-wielding girl, to a flower beast blooming into a powerful mage, the Core's Named Ones rise-loyal, strong, and deeply bound by the magic of their names.

But peace is fragile. As humans invade, rival dungeon cores plot, and secrets of the Core's tragic past emerge, war brews underground and above. With each battle, the Core grows stronger, its influence spreading, its army evolving.

Can a soul reborn as a crystal lead a new race into the light?
Or will the world shatter under the rise of the Dungeon King?
