[ I was reborn as a sin-eater and now I want to eat the demon-king ] After finally leaving behind a life that he hated, Canta is reborn in the depths of a decayed dungeon. With a new body and a powerful, ancient class that is highly revered by the holy-people of the surface-world, he makes a bid to leave the wretchedness of his past existence, as well as his old personality, behind. However, he is not alone down in the darkness. There is something else, someone else, trapped down together with him. Someone who shares his wishes of changing. Someone who is clearly evil. No ifs, ands, or buts about it.
