Cleo just wants to retire from mercenary work and settle into a quiet life, but one last job turns into a bloodbath that should have killed him. He survives only because Kohaku, a demi-human with white hair and the ability to glimpse the future, revives him at a cost to her own strength, then reveals that years have passed and everything he once had is gone. Together they claim an abandoned castle and start over, running a tavern in a land unsettled by the ongoing Divergent Sword Wars.
