D

Demon Sacred

デーモン聖典

A mysterious illness known as the Return Syndrome causes people to physically regress toward infancy until they vanish completely. When a loved one becomes afflicted, a group of friends—Mona, K2, Rina, Mika, and Shinobu—refuses to give up. They set out to infiltrate the leading pharmaceutical company researching a cure, a corporation that suspiciously hoards its knowledge about the syndrome even from its own employees.

To save their loved one, they must navigate dark corporate secrets and face enemies both human and inhuman. Their desperate quest leads them to cross paths with a dragon slayer and a handful of demons, blurring the line between science and the supernatural. As they dig deeper, they uncover motives that threaten to unravel everything they thought they knew.
