In this fantastical tale of demonic battles and courtly intrigue, the onmyoji known as the 'Heretic' faces a destiny that could forever change both human and demon worlds! In an era when only a thin boundary exists between mortal and supernatural realms, demons steal ten powerful artifacts known as the Sacred Relics from the human imperial capital. The emperor issues a decree to the onmyoji who serve and defend the empire: recover the Relics at all costs. Among their number is the brilliant renegade, Fuzuki, who sets off in search of the first Relic.
