In the gritty urban sprawl of modern Japan, high school gyaru Hikari Sato’s life takes a dark turn when a fateful encounter with a demon grants her a strange, supernatural affinity. Pulled into a chaotic world brimming with yokai, cults, and mystical powers, she’s forced to navigate a fragile boundary between the ordinary and the extraordinary. But in a world where no character is safe—not even the heroes—survival is far from guaranteed. As supernatural tensions rise, Area 51, a ruthless empire wielding anti-supernatural technology, hunts down otherworldly beings, and exorcists, bound by their own murky morals, wage an internal war for power. In the shadows, a fanatical cult known as the Sect of Her Shadows emerges, worshipping a mysterious entity, “Her,” who commands the loyalty of the Sect’s Seven Sin Archbishops, each embodying a Deadly Sin. Bound by her authority but driven by their own desires, these figures fan the flames of chaos, and Hikari soon finds herself entangled in their deadly schemes. In a universe devoid of plot armor, each character faces an unrelenting reality where physical death or psychological ruin is possible at any moment. As Hikari fights to survive, wielding an untapped power linked to the mysterious force known as Aura, she unravels her own humanity while grappling with complex alliances, moral ambiguity, and the harrowing horror of the supernatural. With darkness creeping in from all sides, Hikari’s path is anything but clear. Her journey will not only test her endurance but also force her to confront the thin line between hero and monster.
