Slime Seijo

A slime—the weakest of demons—longs to become human and is reincarnated as a saint. The saint’s body belongs to a cunning noble girl with a terrible personality, and the slime must hide its true nature: if anyone discovers it, it will be killed. To secure a safe and comfortable life, the slime starts from the lowest position, where it is despised and disliked. Its goal is to rise from this precarious existence and become a cherished saint.
