Ciel was the youngest son of the notorious shadow clan House Nocturne, spending his life treated as a defective, talentless sacrifice by his cruel family. When his clan throws him into the Abyssal Tomb as living bait, Ciel unexpectedly enters the subterranean sanctum of the Five Primordial Demon Kings, ancient sovereigns sealed away by the celestial gods. Recognizing his bottomless rage and indomitable will, the five demon lords bestow their collective authorities upon him, turning back the hands of time to return Ciel to his childhood inside the Nocturne manor. Armed with five distinct demonic authorities, including shadow manipulation, soul flaying, and absolute kinetic acceleration, Ciel conceals his terrifying power behind a frail, obedient demeanor. Methodically turning the tables on his abusive brothers and corrupt instructors, he turns the Nocturne assassin training grounds into his personal hunting zone. Preparing for the coming continental wars and the unsealing of his demonic benefactors, the youngest son rises to become the supreme lord of the dark.

The world is a harsh continent divided between human imperial domains, secretive assassin territories, and lethal beast-kin lands. At the heart of human political shadow stands the Valgred Clan Estate, an ancient stronghold designed as a meat-grinder to forge deadly killers. Beyond noble territories lies the Dark Forest, a dense expanse crawling with high-rank monsters like Red Ogres and ancient sealed entities. Further outward sit the Falesna Joint Training Grounds - a neutral zone where noble heirs clash - and the sovereign territory of the Agartima Nation, a brutal wilderness ruled by bloodthirsty beast-kin clans who treat humans as game.
Power in this world centers around Mana Cores, Demon Arts, and specialized combat classes like the legendary Sword Saint. Standard human conditioning limits warriors to a single core, but ancient lost techniques allow multi-core cultivation:.

Myriad Dragon Mana Forging Art: An advanced evolution allowing a warrior to cultivate three distinct mana cores simultaneously by age ten. Demon Arts: Elemental combat styles (Fire, Water, Earth) utilized by noble houses to channel ambient mana into destructive physical attacks.

The Thorngrave Empire: The ruling imperial superpower led by Emperor Wilfoen Thorngrave, possessing vast armies and top-tier combat masters. House Dreadgeen & House Centrian: Prominent noble military houses specializing in fiery heavy-weaponry and fluid spear tactics, respectively. The Agartima Beast-Kin Nation: A predatory society of beast-man tribes who operate on pure martial hierarchy and hunter-prey doctrine.
Regression & Memory Retention: Dying while holding absolute resolve allows soul-rebound thirty years into the past with complete strategic and magical knowledge intact. Guardian Spirit Soul Contracts: Ancient entities (such as Genomos) can bind their soul essence to a contractor, granting cosmic authorities like the Star Link and Relation Star. Blood-Pacts & Curses: Absolute rivalries can be sealed through Valgred blood-pacts, while insidious afflictions like the Ice Curse slowly destroy internal mana networks unless purged by dual-core forging.
Betrayed and executed by Emperor Wilfoen Thorngrave after defeating the Demon King in his past life, Glenn regresses thirty years into his infant body as an illegitimate son of the Valgred assassin clan.
