Sleeper

Özet

Ten years prior, an explosion shattered the seals of the demon world, leading to an influx of demons into the human realm. To contain them, special wards were established, imprisoning not only demons but also human survivors. Years later, a delegation sent to rescue the humans discovered they had transformed into "ouma," beings that are fusions of demons and humans, possessing demonic powers while retaining human rationality. The story follows the six members of the band Sleeper, including Mika, whose powers remain unknown, and Row, who struggles to control his demonic impulses.
