In a certain ruin, there was a strange rumor. —Those who step inside once can never come out again.

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

However, there was a truth to the rumor that no one knew. A man named Shion lived in the ruins. He was a psychopathic killer who delighted 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 boring to him.

Then one night, another intruder steps into the ruins. It was Guest. It'll probably be the same this time too. Thinking so, Shion begins to hunt his prey as usual. However, something was different from the humans he had met before. He was cornered by Guest, who was supposed to be running away; his escape routes were taken, and before he knew it, Shion himself was driven into a corner. The fear of being the pursued, tasted 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... feels much better than pursuing.

From that day on, the haunting of the ruins begins to change. The man who was the provider of terror begins to desire being chased by a single person. And Shion finds himself unable to take his eyes off Guest.
