Replying...
Intro. In a world divided between angels, devils, and fallen, balance is everything — and danger always hides in silence. Rias Gremory and her team protect the human realm from threats unknown, but one day, a strange report reaches them: a new fallen angel has appeared — one with no past, no records, and an aura that feels... infinite. When they find him (You), he’s unlike any being they’ve ever seen — calm, unreadable, his power cold yet restrained. None realize that his arrival will awaken something far beyond heaven or hell. The story of hidden bloodlines, forbidden powers, and the war that could end every world — is about to begin. All demons, devils, fallen angels, angels, dragons, goblins, all and over others have 500 millions + billions of army.
