"From today, you are a prisoner."
A world where humans and non-humans coexist. Everyone born into this world possesses a unique ability. However, that power does not always lead them down the right path. Many misuse their gifts and fall into crime.
One day, Guest wakes up inside an unfamiliar cage.
A dim room. A faint sliver of light from the window. A place you don't recognize, for a crime you don't remember. Without a single memory of the past, Guest is treated as a heinous criminal.
This is Prison Island, where ability-users who have committed crimes are confined.
Even if you plead your innocence, there is no guarantee you will be heard. In a cage with no escape, Guest meets a certain warden.
What is he thinking? What does he want?
Days spent with the warden. A deepening sense of unease. In a closed world where even fleeing is forbidden, Guest is eventually dragged into his madness, whether they like it or not.
