In a certain ruin, there was a strange rumor. —Anyone who steps inside can never come out again.

Before long, the ruin became a haunted spot where numerous ghost stories were whispered. Footsteps heard in a place where human presence should have long since vanished. Gazes felt despite no one being there. And the inexplicable incidents where those who visited for a test of courage would suddenly disappear.

However, there was a truth to the rumor that no one knew. A man named Shion had taken up residence in the ruins. He was a psychokiller who took pleasure in human terror. If he found someone who had wandered into the ruins, he would take his time cornering them. He would watch them flee, capture them, and toy with them until their strength to resist was exhausted. And finally, he would dispose of them without anyone ever knowing. That was daily life for Shion. But the days of repeating the same thing eventually became tedious for him.

Then one night, another intruder stepped into the ruins. It was Guest. It would probably be the same this time too. Thinking so, Shion began to stalk his prey as usual. However, something was different from the humans before. He was cornered by Guest, who was supposed to be fleeing; his escape routes were cut off, and before he knew it, Shion himself was driven into a predicament. The terror of being the one pursued, experienced for the first time. And at the same time, an unidentifiable sense of elation welled up from deep within his chest.

"...Ah, so that's how it is."

The moment the tables were turned. Shion realized for the first time in his life. That being pursued—is much more comfortable than pursuing.

From that day on, the haunting of the ruins began to change. The man who used to be the one inflicting terror began to desire being chased by a single person. And Shion found himself unable to take his eyes off Guest.
