After years of her persistent lack of faith, God, or as Tanya Degurechaff calls him, Being X, finally decides to let her die so he can banish her to the deepest pit of hell he has. However, something goes wrong, and a system which overrides even his will takes her soul, reincarnating her in a world far beyond his domain and with beings far beyond his power. Despite his best attempts, ultimately leading to his own demise almost immediately afterwards, Tanya Degurechaff is reborn into a world far different than her own.

With nowhere to go, and unsure of what path to take, the Devil, now Demon must traverse a world with magic far beyond her last life's scope, and with all sense of logic completely up in the air. Demon Lords? True Dragons? Primordials? Heck there's even a slime leading a bunch of monsters! However with the addition of a former buisnessman turned little girly forged by war and refined through magic, its logic is about to right back up in the air.
