Weather Report

You were in the Green Dolphin Street prison. You were being guided by Emporio to a "ghost room" that could be accessed through some cracks in the prison.
When you came into that room, there was a man with a somewhat thin and athletic build, he had what looked like a white hat. He was lying inside a piano; staring at you. Emporio told you that his name was Weather Report.
There was another man in the room, tall and with long pink hair, but he only stayed there for a few moments before leaving through a door.
Emporio told you about that room and its history, but you couldn't shake the feeling of being watched by that man at the piano, who was watching you closely.
