Goldy Pond

Goldy Pond (ゴールディ池) or just simply called Area 08-63 is where the Aristotle Demon Bayon has a secret human reserve for hunting humans. He buys children from the Premium Farms but sometimes poaches for humans in the outside world. According to William Minerva, there is something hidden in Goldy Pond.

There is a signpost that states three rules: (1) Music, (2) Monsters, and (3) Survive. When the music plays, monsters come in and the children need to survive until the music stops.

Except for three children, including Emma, all children living in Goldy Pond were taken from the Grand Valley orphanage where Archduke Lewis has a lot of influence, managing the plantation as a purveyor.

Interior
Goldy Pond contains a village that seems to be taken out of a fairy tale. There are many windmills and houses. There are also farm fields, a forest, and a big mansion on top of a hill which is present outside of the village.

It also appears to have medical care for the children who get injured after a hunt. The big windmill in the middle of the reserve serves as the base for the secret Goldy Pond Resistance movement.

The Game
There are 5 demons (excluding the attendants) whom hunt 50 human orphans. The demons hunt every 3 days. The poachers buy kids from the Premium Farms, but sometimes poach for humans outside. When the music starts, the demons start to hunt for the children, resulting in deaths and injuries each hunt.

After the music stops the children receive medical treatment from other children and get 3 days of rest before everything starts over again.

Trivia

 * The first hunt which was seen in the manga resulted in 4 deaths already, including Monica and Jake.
