Portal Day finally arrives; and as Jinji is relaxing in his room, Phantisserie, Alessandro and Gaspar barge in to inform Jinji about an "issue" in their basement. Always one to take concern as to the safety of his Ghost friends and the stability of the mansion, Jinji immediately rushes to find out what's going on. As soon as Jinji reaches the basement, however, he quickly realizes the Ghosts have been up to something, as he's presented with a wooden door leading to what appears to be a cave, while the Ghosts tease him to open the door.
