Ash Grave is a death god who rebelled against his fellow deities when they resolved to annihilate humanity. Branded a heretic and a traitor, he is feared and despised by the very people he seeks to protect. His partner is Mirim, an elite swordswoman of the Ten Pillars Sword Guild who carries the title Crimson and wields one of the ten divine blades forged by the gods. Together they oppose the Elva Church, a powerful religious organization that secretly works to summon the creator gods back to the world in order to complete their plan for human extinction. The story follows their journey through a land overrun by monsters and mystical threats, unearthing hidden truths about the past, the nature of the gods, and the true purpose of the legendary swords. Early arcs introduce the pair’s uneasy alliance as they clash with the Church’s agents, while a later arc involves a cursed staff that drains the souls of the living. The narrative escalates when the creator gods decide to reset the world, forcing Ash to make a decisive stand to defend humanity. In the climactic arc, Mirim is captured as a witch who tempted the gods, and Ash must rescue her before she is executed. The series concludes with the resolution of the godly conflict, balancing serious fantasy conflict with occasional comedic interludes—such as the pair taking part-time jobs when they run out of funds.
