DXD: The Awakening of Sin
In a cold, hierarchical Underworld where low-class demons are born only to serve and die without trace, Kael Black opens his eyes in a body that is not his own. Reincarnated after a violent death in his previous world—of which the only remaining memory is the sound of his girlfriend’s screams and a lingering sense of helplessness—he is now just another disposable soul in the vast, merciless City of Lilith.
No clan, no status, no protection. No one knows the previous soul committed suicide and was replaced.
For twenty-four hours, he is nothing but confusion, fear, and silence. Then, when he finally rises from the simple bed, a silent, impersonal system awakens before his eyes: a discreet interface, a loading bar, and finally a roulette that spins on its own—displaying silhouettes of legendary warriors from other universes—before settling on a single, permanent, unchangeable archetype.
There is no guiding voice. No easy rewards. No guarantee of survival.
All Kael possesses is a frail body, a mind scarred by fragments of pain, and a slow synchronization with a power that does not copy techniques but shapes limits, style, and potential. A path that advances only through real combat, real risk, and real effort.
As he fights to survive in the stratified streets of Lilith and later in the shadowed halls of Kuoh Academy—where demons, vampires, and mages coexist under a fragile truce—greater secrets move around him. Among them is the concealed existence of Mio Naruse, the unknown half-sister of Rias Gremory, bearer of a power that could shatter the Underworld’s order.
Kael seeks neither vengeance nor redemption. He simply survives—and, little by little, awakens something the Underworld itself has long forgotten: a sin that does not bow, does not break, and does not ask permission to rise.
A story of organic, brutal ascension in a crossover world (High School DxD, Shinmai Maou no Testament, Rosario + Vampire, Fate), where power is not granted—it is seized, blow by blow, wound by wound, choice by choice.
