Oneira

European manga published directly in volume format by Kana.

Born from the depths of our minds, the Nightmares have come to life. Driven solely by the urge to destroy their hosts, these monsters—each taking on a different form—have become a scourge that must be eradicated. In response to this growing threat, the Holy See has established the Epeire caste as its armed force against the creatures of dreams.

Arane Heos is one of them, and as she battles the Nightmares while guarding a secret, she must also confront the unrest stirring within both the Holy See and her own order
