Devil Covenant

On a storm-soaked night, seventeen-year-old Haruto Shikigami loses everything. His parents are slaughtered before his eyes by a devil born from humanity's fears. Yet when death stands before him, Haruto feels something strange—not fear, not anger, not grief. Nothing. That night changes when he becomes the vessel of the legendary Crimson Devil, a calamity responsible for one of history's bloodiest tragedies. Branded a threat to humanity and hunted by powerful factions, Haruto is taken to the Tokyo Institution of Exorcists, where humans form dangerous covenants with devils to fight back against the darkness. Surrounded by prodigies, monsters, and broken souls, Haruto struggles to control the power sleeping inside him. Alongside his teammates—Shimi Horimiya, a girl haunted by a tragic past and the scars of the Blast Devil, and Yamado Kahanru, an arrogant genius who trusts no one—he is thrust into a world of deadly missions, political conspiracies, and ancient secrets. Guiding them is Adryn, an unpredictable exorcist who possesses multiple devil covenants and hides far more than he reveals. As forgotten massacres resurface, powerful organizations move in the shadows, and the truth behind the Crimson Devil begins to emerge, Haruto discovers a terrifying reality: The greatest devils are not always born from fear. Sometimes they are born from humanity itself. In a world where every covenant demands a price, friendships are tested, families are torn apart, and survival often means sacrificing a part of yourself. The question is not whether Haruto can save the world. It's whether he can save himself before the Crimson Devi completely l consumes his identity
