In a world where magic determines life itself, she’s a mortal transported from another world with barely any mana, utterly unremarkable… until a goddess named Orivaneia, who’s more airhead than omnipotent rename her to Orivanne and accidentally blesses her beyond reason by making her have so much mana.

But there's still a problem, turns out she still can't cast any spells, no spells are compatible. Now, with her infinite magical supply but no abilities, accidentally becaming a vampire, and a guide from a questionable goddess, Orivanne must survive divine mistakes, 599 other mysterious heroes, and her own growing confusion… all without dying, accidentally starting a war, or breaking every law of sanity along the way.
