Grace Field Headquarters

Grace Field Headquarters (グレースフィールド本部, Gurēsufīrudo honbu) is the sixth plantation at Grace Field House and the main building from which the farm operates. It is where Grandma, Demons workers, Sisters, and girls training to become sisters and Mamas reside.

Layout
Grace Field Headquarters is made up of a small building above the surface and a large underground complex with nine floors in total. The surface is the only plantation at Grace Field House that does not have a forest surrounding it. The only bridge for going to and from the farm is located in front of Grace Field Headquarters. In contrast to the houses on each plantation, Grace Field Headquarters appears to be full of high tech and modern technology and devices. It contains a sisters school, grandma’s private room, a control room, a CPU room, the Demons private room, the Ratri Clan’s guest room, a nursery for zero to one years olds, a child-birthing room, a hospital/medical care unit, two storage rooms, an execution room, the Sisters quarters, the Demons quarters, a flower garden, a sewage/power room, and a portal to the Human World located on the lowest floor.
