In the late-medieval land of Barnard, between the mountains and sea, the peaceful lifestyle of the people has been shattered by fear. Monsters known as the Dark Ones roam the land, killing indiscriminately. The townsfolk fear to venture out from their homes, and travel from town to town has become a risk to life and limb. To protect the people from this terror, several guilds have sprung up, including the Guild of Assassins and the Guild of Mercenaries. To go out into the world, or travel across the wilderness, hired mercenaries are essential. One man has built a reputation as an especially fierce monster-killer ‹ a man known as Leroy Schwartz. A former high-ranking member of the Guild of Mercenaries, Leroy has struck out on his own. Many try to hire him for his superior skills, but Leroy has his own agenda. He has a mission to accomplish, a vow to fulfill. This vow is known only to himself, and his one companion: his sentient long-sword Ragnarok. (Source: Anime News Network)

Nero is a young man who works in the island castle-town of Fortuna for The Order of the Sword, a sect of holy knights who revere the demon Sparda and are led by their benevolent spiritual leader Vicar Sanctus. During the Festival of the Sword, Sanctus is murdered by a mysterious man in a red coat who then escapes, Nero is tasked with finding the unknown figure and sets out to trace his steps but over the course of the search he encounters with the dark side of the Order.

The series is set 150 years after humanity lost half of the planet due to a mysterious "black fog." To contain the "black fog," 3,000-meter-tall (about 10,000-feel-tall) walls were erected to split the world, and the half of the human population that survived now live in cities called "Arks." Shidou Enishi, one of the few Japanese survivors, runs a detective agency on the ninth ark. While pursuing a male suspect in a burglary, he learns of a massive conspiracy, one that may be tied to the Rivigarudo syndrome that is mutating its victims into something inhuman.
