Slime Saint

When a curious slime monster comes across a fresh corpse, an opportunity presents itself: take over the body and become a human. Easy, right? Except, the body that the slime took belongs to Lady Jelly, a heinous, unhinged young noblewoman whose villainous personality may be the reason why her corpse ended up in the forest. There's no turning back for this slime—the only thing she can do is turn this villainess into a beloved saint! But if her true nature as a slime is discovered, this dream will be over before it even starts. Can a simple slime change Lady Jelly's reputation and keep herself alive in order to become a beloved saintess? Or is this weak creature doomed to stay at the bottom of the food chain forever?
