Grace Field House

''This article is about the Manga version of the Grace Field House. For alternate pages referred to by this name, please click any of the icons above.''

The Grace Field House (ハウス) is a 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 female humans known as Mamas, who also double as caretakers for said children.

It consisted of five plantation, a headquarters and a central area that connects the Plantations and HQ together. It is formed in a hexagonal shape. After the fire and destruction of plantation 3, Grace Field House only consists of active 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.undefined

History

 * Main article: Demon World

Grace Field House, similar to every other plantation, was built in order to keep children as livestock for the demons to consume. Following the Demons and the Ratri Clan's promise to not hunt each other, the humans who fled from the demon world to the human world gave some of their children as a parting gift. Said children were later kept in plantations.

In comparison to other Factory Farms, Grace Field House is a Premium Farm, which means that it's a farm that is solely made for the premium or high-end farming of human meat. The children at the premium farms are all valuable.

Building
The Grace Field House is a European-styled home, standing three stories tall with blue roofs and light orange walls. Inside the house consists of a cafeteria, an infirmary, bedrooms, a library, the test room and Isabella's office.

Secret room
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.

Layout
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 forest area of demon domain called the Demon Forest. There is also a pathway to the human world inside the farm. 

Litany Tests
These tests are given daily in order to polish the brains of the children. The orphans in Grace Field have to sit through daily tests, which will make them more academically/mentally inclined. The highest score an orphan can get is 300. The shipping order of all the children is based on how high they score on the IQ test.

The tests in Grace Field House focus on information analysis. Problems are distributed according to age group. Taking of tests starts at 4 years old, those who are below 4 years are playing in a nearby room. All the children (except those that scored full marks) are given homework, as shown in the extra pages of Volume 3 of the manga.

Transmitters

 * Main article: Transmitters

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 these transmitters help 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, as 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.

Radar

 * Main article: Radar

The radar is a small, technological device used by the caretakers in the Premium Farms. 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 take the appearance of pocket watches.

Shipments
Children are shipped out between the ages of 6 and 12. Age also determines the rank of their quality, with 6 being the lowest, and the normal quality.

The test scores determine the shipment date orders. After the children reach the age of 6, the lowest scores will be shipped out first. Those who have full scores will be shipped out no matter what once they turn 12.

Test scores determine the shipment date orders because of the size of their brains. The more developed brain, the better, thus qualifying as the highest rank.

They are shipped out at night on the day of their 12th birthday or when their shipment date has been decided.

Appointing Girls as Caretakers
Girls who are 12 years old and clear a set of successful requirements are given two options: One is to be killed and the other is working as a caretaker.

One must have satisfactory grades and a recommendation from their own Mama in order to be appointed as a caretaker.

Microchips
Microchips are embedded into the young girls who are willing to become caretakers. They are embedded in their hearts and are programmed to send an electric shock to their hearts if they take a step outside of their grounds. They are also programmed to send an alert to the higher-ups if the heart stops on its own for varying reasons.

Trivia

 * In William Minerva's Promised Pen, the location of the Grace Field House is 00-00.
 * The orphans from Grace Field are identified by a 5 digit ID number tattooed onto their necks. It is possible that these numbers are allocated serially and are meant to be read from right to left
 * Isabella is the oldest known orphan from Grace Field and has the ID 73584 (48537). Krone is the next oldest and has the ID 18684 (48681). Emma, Norman and Ray are the same age and have IDs 63194 (49136), 22194 (49122) and 81194 (49118) respectively. From this, it can be deduced that Ray is the eldest, followed by Norman and Emma.
 * Isabella and Krone have an age gap of 5 years (2014 vs 2019) and their IDs are 150 digits apart. This suggests that Grace Field harvests 30 children annually; each house harvests 6 children annually, or one every 2 months. This is consistent with the "adoption" of a child every two months. Extrapolating further, Grace Field would've been in operation for about 1,638 years when Emma was born.
 * In 2019, the Yakusoku no Neverland website ran an April Fools joke that a real life Grace Field Nursery would open, accepting enrollment applications for children ages 1 to 12.
