Crimson Grave

A long time ago, a demon caused widespread death before being defeated by ten world-creating gods. To safeguard peace, the gods crafted ten powerful swords. Mirim is part of the 10 Pillars Sword Guild, recognized as an elite warrior known as Crimson, and possesses one of these divine swords. She is partnered with Ash Grave, the legendary devil. The pairing of a divine protector with the demon from the past raises questions about the true nature of the story and the roles these two play.
