Grand Valley

Grand Valley (グランドバレー) is one of the four Premium Farms where orphans were raised as livestock for the demons. Just like the Grace Field House, Grand Valley has appointed caretaker(s) to raise orphans that will later be butchered for demons to consume. Every month, some children from this farm are shipped out to Goldy Pond to become prey for the Poachers to hunt.

Appearance
Not much of Grand Valley's appearance is known, but it is known to be very large and it has multiple buildings placed in a town-like formation. Instead of using radar, Grand Valley is located inside of a giant dome to prevent the children from escaping.

History
1,000 years ago, the world was plagued by a war between humans and demons. In an attempt to end the war, a proposal —otherwise known as The Promise— was formed by the first head of the Ratri family and. It declared that "Human beings shan't hunt 'demons' anymore. In return, 'demons' shan't hunt humans." Afterwards, the world was broken into two — one side belonging to the demons while the other belonging to the humans. As per the agreement, as small number of humans were left behind in the Demon World to satisfy the demons need to eat humans. These humans were later kept in plantations known as Premium Farms or Factory Farms to be raised as livestock for the demons to consume. While there are hundreds of Factory Farms, which are for mass production of cheap meat for demon civilians, there are currently only four Premium Farms which produce high quality meat for wealthy and high ranking demons.

Grand Valley, similar to every other plantation, was built in order to keep children as livestock for the demons to consume. In contrast to the Factory Farms, Grand Valley is a Premium Farm, which means that it is a farm that is solely made for the premium or high-end farming of human meat. The Grand Valley 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. Like all of the Premium Farms, there is a pathway to the Human World somewhere inside of Grand Valley for bringing food, toys, clothes, and others supplies to the farm.

As with all of the Premium Farms, the plantations at Grand Valley are designed to make the children's brains develop as much as possible by providing the them with everything they need to be happy and comfortable with minimal stress. The children are served gourmet food, sleep in plush beds, and are even permitted to celebrate their birthdays and holidays such as Christmas. All of the humans at Grand Valley (both adults and children) are identified by an identification code tattooed across their upper chest, that starts with a letter, then has a sequence of Roman numerals, followed by a 3-number sequence, a dash, and 3 more numbers.

In 2047, Grand Valley was abolished after the enactment of Emma's Promise, which declared all farms be shut down and all of the surviving orphans be sent to live in the Human World.

Tests
Everyday, the orphans are required to take tests under the guise of "schooling" which will make them more mentally and physically inclined. When in fact, these tests are designed to determine their quality as livestock. These tests are given daily in order to polish the brains and bodies of the children. The shipping order of all the children is based on how high they score on the test, with the lowest scoring child at each plantation being shipped out roughly once every two months.

While six is always the youngest minimum age to be shipped out, each Premium Farm has a different maximum shipment age. For Grace Field, the maximum shipment age is twelve, for Glory Bell it is fifteen, and for Grand Valley it is seventeen. This is because each Premium Farm focuses on different developments in their livestock. Grace Field focuses solely on mental development and thus six years old is the minimum age to be shipped out of Grace Field because the human brain is said to be 90% developed by age six, and according to the manga, by age twelve it is completely developed. Whereas Glory Bell and Grand Valley focus on mental and physical development thus qualifying for a higher maximum shipment age to make their bodies more physically developed.

Trivia

 * Instead of having Mothers as their primary caretakers like Grace Field House, the primary caretakers in charge of the plants at Grand Valley are called Teachers.
 * Grand Valley is the only Premium Farm that ships a few children to the 'Hunting Playground' once a month.
 * Olivier, Zack, Gillian, Nigel, Violet, Sandy, Paula, Sonya, Pepe, and Theo, are all from different plantations at Grand Valley and thus did not know each other during their time at the orphanage.
 * This also means Grand Valley consists of at least 10 plantations compared to Grace Field's 5.
