Premium Farms

The Premium Farms are farms that are made solely for the premium or high-end farming of human meat. The children at the premium farms are all very valuable, in contrast to the Factory Farms, which are for the mass production of cheap meat. There are only four premium plantation farms, including the Grace Field House, while there are hundreds of Factory Farms.

History
Located in the demon world, the Premium Farms were built due the "Promise" made between the Demons and the Ratri family 1,000 years ago. It is unknown exactly when the Premium Farms were built or in what order, but it is implied that they have existed for hundreds of years, if not the full 1,000 years since the "Promise" was enacted. The Grace Field farm did not exist 1,000 years ago. There were previous versions of top-grade farms, but it required around 400 years to come to the current form. While there are hundreds of Factory Farms, which are for mass production of cheap meat for demon civilians, there are only four Premium Farms which produce high quality meat for wealthy and high ranking demons. The orphans in the Factory Farms are kept in poor conditions and are barely alive, while the orphans in the Premium Farms are raised in a good and safe environment so they can grow up healthily, develop smart brains, and make good meals for the demons. Since the livestock that comes from the Premium Farms are supposed to be the highest quality, any children born on these farms with birth defects or deformities (such as Ayshe) are to be disposed of shortly after birth. Grace Field is regarded as the top Premium Farm with the hardest litany tests. Grace Field is also the smallest Premium Farm, being made up of a single building on each plantation. The other Premium Farms are made up of several buildings and have the appearance of villages. There is also a pathway to the human world inside each of the Premium Farms, likely for bringing food, toys, clothes, and others supplies to the farms.

The children at the Premium Farms are all valuable, in contrast to the children at the Factory Farms. The meat sold from the Premium Farms are of high quality and are sold at hefty prices to wealthy Demons, or are saved for, the demon king, to consume.

Life at the farm

 * Before the kids are sent to the farms, they receive Transmitters inside their ears so that the Mama of their respective farms can use her Radar to locate their current location.
 * Only sumptuous and gourmet meals are served inside these orphanages.
 * The children are required to take daily tests. This is a substitute for a real school and prepares the children for life outside of the orphanage. It is later revealed that the tests are necessary to make the children's brains delicious for the demons to consume.
 * All the uniforms are white.
 * It is implied that, with the exception of Grace Field, all premium farms have a fake sky.
 * The children at Grace Field have an identification number on their neck, but not all farms do. In Grand Valley, the children have a code with numbers and letters on their upper torso.

Shipment

 * Only kids who are 6 or older get shipped out.
 * The shipment order is based on scores: the highest score is 300 and the closer an orphan gets to the 300 mark, the longer it takes to get shipped out when the orphan is older, like Emma.
 * There is a shipment at least once every two months, where the child with the lowest score between the age of 6 and 12 is shipped.
 * The maximum age for the shipping date is different, depending on the farm. For example, it's 12 years old for Grace Field, but 15 for Glory Bell, and 17 for Grand Valley.

IQ Test & Scores

 * The kids in the farms take tests daily.
 * If a child scores lower than 120, the shipping date will be hastened.
