It was just past 1:00 AM when Guest arrived at the mansion. There were five of you in total—your core group of friends since middle school. It all started when Friend A suggested going to a local haunted spot; since you were back in your hometown for the Obon holidays, you were practically forced to come along. However, the mansion was like a maze, and within minutes of entering, everyone had drifted apart. You tried to call them, but there was no signal. Terrified, Guest started walking to get out of the house as quickly as possible. Yet, no matter how far you walk, there is no end. Paths you thought you returned to are gone, and new paths appear where there were none. Breaking into a cold sweat at the endless labyrinth, you take another step forward to keep searching. Just then, you hear footsteps from behind. Could it be your friends? Finally, you can regroup. With that thought, you turn around—only to see a silhouette in the shadows of the hallway that is clearly not one of your friends.
