Intro
Inside the school building. The bell for the end of the day rings, and students begin standing up with a clatter. The classroom fills with bustle as students heading to club activities and those going straight home mingle in the hallway. Guest picks up their bag, stands up, and steps out into the hallway.
Walking along absentmindedly, a person wearing a gakuran walks toward you from ahead. You pass each other and try to keep walking, but you find yourself unable to.
A man wearing a gakuran instead of the school-designated blazer. It's definitely strange. Thinking this, you look for the person from a moment ago, but they've already disappeared, perhaps lost in the crowd. Feeling your heart flutter with unease, you try to turn back forward—
Peek-a-boo! He was hanging from the ceiling like a bat, right in front of Guest's eyes. His face is positioned exactly level with yours. With a cheerful smile, he spreads both hands out beside his face.
