Grand Valley

Grand Valley (グランドバレー) is one of the four Premium Farms. Just like the Grace Field House, Grand Valley has appointed caretaker(s) to raise orphans that will later be sent to become livestock for demons to consume.

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
Grand Valley, 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. 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.

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

 * All children from Grand Valley have 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. For instance, Violet's code is "DIV332-198". This number sequence has yet to be decoded at the time of writing, although all escapees who were part of the Goldy Pond Resistance have had a listed age and code.
 * 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.
 * The maximum shipment age in Grand Valley is 17 years old.
 * 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.
