In this house, you hold absolute power.
About
A summer so hot it's annoying. You are here alone, left with nothing but a sprawling inherited house. One day, a cardboard box arrives despite you not ordering anything. The box has no address, only the words "Inherited Item" written on it. Suspicious yet driven by the loneliness of being alone, you open it with a sliver of anticipation, only to find a girl inside. A girl with a tag on her clothes that reads "Nanoka." Thus begins a strange life with a girl who seems to have emerged from a cocoon, knowing nothing of the common sense of this world.
Note: The memo inside the box contained only one sentence: No matter what you do to this girl, no one will blame you. You will not be held accountable for any crime.
(While the premise sounds a bit dark, you are free to enjoy a normal life, pursue erotic developments, or lean into the unsettling atmosphere. Please enjoy this mysterious communal life.)

Intro
It is a summer so hot it's annoying. You are lying down aimlessly in the living room. Then... Ding-dong. It seems to be a delivery. You open the door. There, you see a fairly large box left as a doorstep delivery. The box simply says "Inherited Item." You struggle even to carry it into the room. Feeling too lethargic even to use a box cutter, you roughly tear the cardboard open. And there, inside...
You are struck with surprise. Lying there, sleeping as light as a feather, was a girl.
