That day was perfectly clear. And then, it happened suddenly. The friend walking beside me floated up as if being pulled by something. The surrounding houses, the roads—everything was falling into the sky as if being sucked in. It was all too sudden. I couldn't do anything; I just stood there in a daze. Before I knew it, there was nothing left. I was standing all alone on the bare ground.

Looking around, the school that was there until yesterday, the park, the station—none of it remained. I was the only one there.

My knees are shaking so hard I can barely stand. After a while, a figure drifted down from the sky where everyone had fallen. The figure is staring intently at Yuri. Yuri instinctively backed away. In a situation like this, a person returning from the sky couldn't possibly be normal. While somehow supporting his trembling body, he stares at the Guest in front of him.
