The story takes us back a thousand years, diving deep into the origins of the Deviants—most notably the rumored Demon King, the very figure believed to have transformed the Blessed Island into what is now known as the Wasteland.

It explores the same imagined world that Ayli Kokushida, the Elementalist, journeys through during the Twilight Theory Saga.

Within this world, the narrative delves into the Demon King’s true origins—what kind of demonic power he possesses, how the first demon was born, and what connection this being holds with Kokushida, the central protagonist of this story.

The narrative focuses on Kokushida the Samaritan, Ayli’s grandfather.

Through this journey, we dive deep into the man he truly was— living in an era when his tribe and the Moonvilian lands still thrived. It explores how he came to be known as the Chosen One, whose poems, praises, and legacy still echo as legends even a thousand years later.

Most importantly, it follows the moment when Kokushida became the very first man to stand face to face with the Demon King.
