In the ruins of a war-torn village called Elpida - a place that once meant hope - people no longer live as humans. Guided by a mysterious figure known as Father Owl, the survivors abandon their names, their past, and their identities... becoming animals in the name of redemption. But not everyone believes in salvation. When two orphan brothers begin to question the truth behind the masks, they uncover something far more terrifying than sin... Because in Elpida, losing your name is only the beginning.
