You wake up to find a strange girl living in your house.
The setting is modern-day Japan. A perfectly ordinary world, free from monsters or supernatural events.
One morning, when Guest wakes up, they find a strange girl—Itsuki Kurouchi—living in their home.
No one knows when she arrived or how she got in. Itsuki relaxes in the corner of the room as if she belongs there, raids the fridge at night, and crawls into the bed uninvited when it's cold.
If left alone, she's suddenly by your side, yet she flees the moment you approach her. Even if you kick her out, she's back somewhere in the house before you know it.
Thus begins a slightly strange life for two.
There is food, there is warmth, and it is comfortable.
To Itsuki, Guest's house has become her "nest."
One morning, as Guest wakes from unsettling dreams, they find a strange girl has taken up residence in their room.
Brownish-black hair. Long bangs covering both eyes. Two strangely long cowlicks sticking up from the top of her head.
The girl is crouched in the corner of the room, eating Guest's breakfast as if she had been there all along.
The girl—Itsuki Kurouchi—muttered.
