Nightmare Knight ~Sacred Maiden & Fallen Magic~

The young girl Rayne, who became the sacred knight of the kingdom, was entrusted by Jas, the leader of the sacred knights and her lover, to investigate the disturbances occurring in a distant town named "Hakudeti". These disturbances involved a surge in criminals in the previously peaceful town of Hakudeti, an overflow of monsters in the nearby areas, and even the appearance of a mysterious dungeon.
