Within the World Dungeon, there is but one mandate, survive.

As a young crippled boy, Luca should have been counted among the ranks of the dead killed by monsters when the dungeon emerged. Whether by chance or providence, Luca survived and was granted the legendary class of the Accuser, the ancient name of the Black Angel of Death. With his newfound power, Luca must work to survive every floor of the dungeon and seize the Alter of the End if he is to survive.
