He transmigrates to another world and becomes a slime. By a twist of fate, he finds a girl who has completely died.
Using his slime abilities, he absorbs, analyzes, and studies the girl, who is already dead. After successfully mimicking her, he also inherits her memories. It turns out that she was the younger sister of a countess in the Re-Estize Kingdom.
She may not be a countess herself, but she's still a noble. She has no ambitions. Being a noble and living a lazy life is all she wants.
But fate has other plans. After an incident, she soon learns that the Great Tomb of Nazarick will arrive in this world before long.
She doesn't want to be treated like a two-legged sheep and sent to Little D's happy farm, or become a snack in the Neuronist Painkill's dessert room. And she certainly doesn't want to frolic with the Black Goat's young. So she decides to step up and become an idol...
No, not an idol. She'll open portals to other worlds and find the ultimate power to stand against the Great Tomb of Nazarick!
