Dungeon Builder: The Demon King's Labyrinth is a Modern City! (Manga) ...

“TAKE MY POWER!”

The dreaded white plague has reached Avalon, but Procel and his followers are able to eradicate even it, forcing the Demon Lord of Darkness to launch his next attack...beginning with the kidnapping of Rorono, the pillar of Avalon. Procel orders a rescue mission with Avalon's strongest warrior, Quina, taking the lead and attacking Agares, the Demon Lord of Domination. But Quina is swiftly overpowered, and the only way to aid her is for Procel to unlock “The Awakening,” a forbidden technique that could make one go berserk, consumed by the lust for power. Could tapping into "The Awakening" prove to be Creation's undoing?
