The Grace Field House is symmetrical flat-hexagonal complex used to raise children as livestock for the demons. It is unique, being one of the four known Premium Farms. It is entirely operated by humans known as Mamas, who also doubles as caretakers for the said children.
It consisted of five Plantation Farms, a headquarter and a central area that connects the Plantations and the HQ. It is formed in a hexagonal shape.After the fire and destruction of plantation 3, Grace Field House only consists of four plantations.
The entire complex is surrounded by walls. Beyond the walls lies a deep cliff. Both act as security measures to prevent the children inside from escaping.  The only known practical way to leave the complex is by using bridges that connect the HQ to the outside world.
HistoryMillennia ago, before the construction of plantations, both demons and humans shared the same world which leading to frequent hunting of humans by the demons. Some humans soon after did the same, while the rest worshipped them out of fear of getting eaten. This became a continuous cycle as both sides killed and feared one another. After countless violent wars and massacres, a group of humans called the Ratri Clan stood up to the demons and made a treaty known as The Promise.Citation needed
Bayon and the government of demons held a meeting, discussing how they should consume orphans when they are forbidden to do so after the Ratri clan's proposal of a treaty. Bayon came out with the solution of building the farms to "cultivate" the young of the humans so to satisfy the demons' need of consuming human flesh, as well as to comply with The Promise. Therefore, Bayon's solution was accepted and included as part of the treaty.
The Signing of The TreatyA proposal —otherwise known as The Promise— was formed by the first head of the Ratri family. It declared that ''humans and demons are restricted from further hunting.'' Not long after, the world was broken into two — one side belonging to the demons while the other belongs to the humans.
Birth of the 5 Premium Farms
Afterward, humans gave some of their children to the demons as a parting gift when they fled from the demon world. The children were later kept in "plantations" (institutions that take care of the children) as livestock for the demons to consume.
Thousands of such plantations held offsprings of humans who were kept in poor conditions, as the offsprings never got proper education or food, they are known as Factory Farms.
Premium Farms, on the other side of the spectrum, are farms that are solely made for premium or high-end farming of human meat. The children at the premium farms are all very valuable, in contrast to Factory Farms, which are for mass production of cheap meat, the meat sold from the premium farms are of high quality and are sold at hefty prices to the Demons, or are saved for the demon king to consume. Four of these five farms are – Grand Valley, Glory Bell, Goodwill Ridge and Grace Field.
The Grace Field House is a European style, three stories tall building with blue roofs and light orange walls.
A room hidden from the orphans, located within the adjacent walls of the orphans' bedrooms served as a headquarters for the caretaker, Isabella, to access.
Surrounding the house is a vast, grassy field which reached out to a small forest where the orphans would use to play a game of tag with, and a gate which serves as the entrance to the house, and a linkway to the Premium Farms' headquarters.
A few areas surrounding the perimeter of the complex is considered to be a deep cliff. However, evidence showed later in the story that it is in fact in the middle of a forested area of demon domain, called the Demon Forest. There is also a pathway to the human world inside the farm.

Transmitters are microscopic crawlers that are stapled into the ears of all the orphans in the Grace Field House. Their true form is unknown because they are not externally visible. The use of this transmitter helps a caretaker to track down the whereabouts of an orphan via a radar.
A disadvantage of a transmitter is that it would be useless if the host is near the gate or the wall which surrounds an orphanage, as it would eventually lose its signal. The transmitter will also be useless if the device – invented by Ray – is applied onto the ear of an orphan which contains the transmitter, the device could cripple the transmitters and render them useless. It was crafted by Ray using parts of an instant camera, an old video game console, an iPod and other gifts which he received from Isabella for being obedient to her as her spy.Citation needed

The radar is a small, technological device used by the caretakers in the Premium Farm. The radar can locate orphans who have the transmitters implemented into their body, specifically the back of their ears for the orphans in Grace Field. The radars are designed to be light and durable for the caretakers to carry around. They resemble makeup mirrors with chains attached.
A disadvantage of the radar, as mentioned by Krone, is how the user cannot identify who the marks on the transmitter represent. Nevertheless, the disadvantage does not restrain the radar from tracking down individuals, specifically orphans, as it is capable of tracking them from far distances.
