This is a Galgame/visual novel with a single character and a single ending. The playing time is about two hours.

After meeting with Lilith for a while, she returned to her hometown of Devil because of something, and at the same time was a life-like doll sent by her as a souvenir.
I thought it was just an ordinary (although not ordinary) gift, but I didn't expect the doll to be active at night.
The day of living with a living puppet without a name and no heart starts like this.
