Sato Killing Time Chat.exe

Sato Killing Time Chat.exe is a short-form ARG (Alternate Reality Game) mystery where players communicate with a mysterious girl named "Mina" through a chat interface. This isn't just a game inside a window - it’s an experience that bleeds into your real world. Players launch a specific chat app on their PC and exchange messages with a girl named "Mina." An outcast at school and estranged from her family, she reaches out to you with a simple request: "Kill some time with me." Investigate a web of multiple fictional pages - furniture stores, news sites, social media, and corporate homepages. Everything is a clue leading to the "answer," from hidden codes and names to a single sentence in a comment section.
