nestled within the tranquil environs of an orphanage named Eden Farm, a haven for numerous children who had lost their families and found themselves homeless, resided a motley crew of 36 young souls. Their days were filled with labor, play, learning, and testing, among them, two extraordinary individuals - Amara (voiced by Rinko Kikuchi) and Noman (voiced by Tatsuhisa Suzuki). The matronly figure overseeing their care was Isabella (voiced by Yu Aoi), affectionately known as "Mother" by the children. Each departure of a child, signifying adoption, served as a beacon of hope for the ones remaining.
One fateful day, Amara stumbled upon a hidden truth lurking behind the orphanage - the children who left were not adopted but slaughtered, and the inhabitants of Eden Farm were, in fact, its livestock bred for... a grim purpose. This chilling revelation shook the very foundations of their world, and the surviving children vowed to uncover the truth and find their place in this twisted reality.
