Demon Lord, Retry! R

Hakuto Kunai resumes his adventures as Rabbi Village expands under the management of Isami Tahara and Yuu Kirino. He heads to the Prison Labyrinth in Rookie Town, where he discovers a secret laboratory with technology that's far more advanced and potentially hazardous than anything in the world. This laboratory gives Kunai a new understanding of countermeasures against magic. The Holy Kingdom of Light and the State of Right face a potential threat from the Queendom of Xenobia, which is trying to drive a wedge between them, but Kunai's new ally Akane Fujisaki may disrupt these plans.
