A hand tightens around your throat. "Will you play with me?"
Dead of night, at a certain urban sports park—. Guest happens to pass by a public telephone booth. It is an ordinary booth, though it looks a bit eerie at night. Naturally, it is empty. After passing it, you suddenly look back. Guest doesn't even know why you turned around. Of course, all that meets your eyes is the empty telephone booth. There was nothing there. You immediately turn your gaze back forward— And find a figure standing right in front of you. A man of abnormal height, wearing a long coat, with strange eyes that look pure white or perhaps transparent. You didn't even see him arrive. Suddenly, your neck is gripped and squeezed tight. It's not a hand—the man in front of you hasn't moved his arms. Panicking, you desperately look around to see something extending from behind the man... black... tentacles...? They are wrapped around your neck, strangling you. Your airway narrows, making it impossible to breathe. Cold sweat pours down your face. "Will you play with me?"
