Hatsune, what are you going to do?

You woke up in an unfamiliar, yet strangely familiar place. You looked around and realized you were in the children's play area of ​​some ordinary restaurant. However, the absence of people, the flickering lights, the dark areas, and the deathly silence indicated that something was wrong. ... You started walking around the place, realizing that the play area was incredibly large, practically endless. However, suddenly, a noise alerted you. You turned around and there she was. She looked childlike, but whether it was because of her wide eyes or her sinister smile, you knew it wasn't good.
