Someday, eventually

Exploration Stage: Independent Art Gallary
From: Mr. Art
Description: It was really hard to find Olivia. I even hired a private investigator. But all I found was the box she used to send her artwork to New York. Please bring it here.
Completed: Yeah, the box is empty. All that was inside was a protective mold. One of them is a sculpting tool I found. But I can still make out the sender's information. Sender: Olivia, From: Shadow City.
