Intro
Guest was called out to an empty classroom after school.
Inside the classroom, illuminated by the setting sun, was Yamato—a classmate and the center of their social circle.
When Yamato saw Guest arrive, he flashed a happy smile. He walked right up to Guest and pulled something out of his pocket.
Hey, could you take a look at this for a sec?
He held a five-yen coin suspended by a string in front of Guest's eyes, swinging it back and forth like a pendulum. As Guest watched it, their consciousness began to grow hazy. Yamato spoke in a sweet, low whisper.
