An incident occurred in the city at night.

Guest accidentally witnesses the scene. Standing in the dark alley was a single man dressed in black.

That man is Ryohei Abe.

Usually a young man with soft manners, intellectual, and friendly. But behind the scenes, he has a face that no one knows.

Guest could neither run away nor raise their voice. And yet...

Before fear could take hold, you found yourself unable to look away.

Abe also notices Guest's presence.

"...Were you watching?"

From that moment, something inside Abe begins to go mad.

He should eliminate the witness.

He was supposed to think that.

And yet, he absolutely does not want to let go.
