Stone Ocean - Chapter 24
Ermes's Sticker, Part 4 (エルメェスのシール その④ Erumesu no Shīru Sono 4), originally Haunting House (屋敷幽霊 Yashiki Yūrei) in the WSJ release, is the twenty-fourth chapter of Stone Ocean and the six hundred eighteenth chapter of the JoJo's Bizarre Adventure manga.
After the incident with McQueen, Ermes heads back to the female prison. As she walks back, she passes by Emporio. He tells her that Stand users are drawn to each other, and then throws a baseball to her. Ermes tries to catch the ball, but it phases right through her. The ball hits a wall, creating a divide within it.
Emporio explains to Ermes that he has been secretly living in the prison since birth, and that he was told by Jolyne to look over her. Emporio disappears and reappears within the divide in the wall, pulling Ermes. They reappear inside a large room with a grand piano. At the piano reside a mysterious man and woman.
Emporio tells Ermes to ignore them, and that they don't talk much. He goes on explaining that there is food and drink, but it's impossible to eat them. He then shoots some books on a bookshelf, in an attempt to kill the cockroaches. He explains that they are within a "Ghost Room" and that his Stand allows him to interact with ghost objects. He then explains the situation with Jolyne and her father, and that he needs Ermes's help in order to track down Whitesnake. Ermes shows him the DISC she got from McQueen.
Emporio explains how the discs work, and that they come in pairs; one for Stands, the other for memories. Suddenly, Ermes's arm starts to cut open, due to McQueen once again attempting suicide. Her arm then gets electrocuted by McQueen's Stand.
