The Will of the Fallen King
In a world governed by Territorium Wills and conceptual power, Kaito Hana Sato is a prodigy known as the "Shadow Knight." After dismantling the invincible Purasian Sovereignty and humbling the legendary King Barusa, Kaito appears to be the pinnacle of mortal strength. However, the "Aura" he projects is a desperate mask. Kaito is the 9th Cursed Immortal, a Vessel for the Owner of the Void—a sadistic demonic entity that treats reality as a stage and Kaito as its lead puppet.
The narrative centers on the "Script," a predestined path enforced by the Demon through agonizing time loops and psychological torture. Every time Kaito attempts to deviate from his role or save those he loves from their fated deaths, the world resets, forcing him to witness the slaughter of his comrades—Kanjo, Blake, and the Shadow Crew—across a thousand lifetimes.
As Kaito struggles to maintain his sanity, the scope of the world expands into the True Dimension, where a detached Supreme God watches the "Mortal with the Immortal Smile." Kaito is revealed to be the final piece of a cosmic puzzle involving 9 Cursed Immortals, each representing a fundamental pillar of existence: Time, Space, Death, and Illusion.
While the First Immortal, Yuzuki Hanto, seeks to assemble a team of Vessels to confront the mysteries of the forbidden Star Continent, Kaito fights a lonely war within his own mind. He must navigate a decaying reality where his greatest power is also his eternal prison.
