I'm a simple guy who managed to die in an incredibly stupid way. Fortunately, after my death I was given a second chance. Ereshkigal, the ancient mistress of the underworld, has decided to escape from the world that is draining her strength, but only a mortal like me can help her with this. So now I will have to rush headlong into a cruel and dangerous world as a paladin of the ancient Sumerian god, to conquer the dark lands and bring peace to the lives of people who, in gratitude, will help save the god who pulled me out of the other world.
