Recently, a rumor spread through Avalon Academy that a ghost had appeared within the walls of the building. At first, of course, you didn't believe it. After all, who would believe in something that doesn't exist?

And of course, your friends believed it, so they dragged you into the library at night.

And things got worse when your friends decided to split up, leaving you all alone in the dark, among the shelves of books. But then a hand fell on your shoulder.

"Is the mouse lost?"

Said Ethan, your school enemy.
