Mama

Mama (ママ), is a title given to female humans who are serving the Demons' "dietary goods" under the guise of being a caretaker for orphans in the Premium Farms like Grace Field House. They are former "orphans" and former "Sisters" who have proven to be capable of having children and have surpassed an insurmountable level of expertise in the Litany Exams as well as spent a lot of time of training. Being a mama is one of the highest rankings a human can receive at Grace Field House and therefore is a position that is heavily sought after by the Sisters and girls training to become Sisters. Because there are only five plantations at Grace Field House, it is likely that there are only five of these positions. The Mamas are supervised by a Grandma appoints them to to their position, and is the only higher ranking human than them at the farm. The Mamas run the "orphanages" and serve as the main caretaker to the children. The Mamas are well trained in a variety of areas and accompany the children as they are being "shipped out". While they appear to be very kind, loving, and affectionate to the children, they are actually cold, calculating, and show much detachment to the children's tragic fate. They must keep up the orphanage facade and continue their hard work or risk getting killed themselves. There is a secret room inside each house in which the Mamas report in to Headquarters every night and are informed about who the next "shipment" will be. Like the Sisters, they have chips in their chest that do not allow them to leave their farm. If they leave farm property, they are immediately killed using the chips implanted on their heart.

Appearance
Mamas can be seen wearing a black dress with white collar and buttons coupled with a white apron on the top of their dress, with a pair of brown boots and black leggings underneath. Their uniform also shares design with the sisters'.

Trivia

 * There are numerous other Mamas in the other Premium Farms
 * Mamas and sisters have some difference in their jobs, if sisters are assigned by a grandma to assist their mama at a premium farm, mamas are assigned to manage and take control of the farm.
 * The hierarchy of the farm adults are similar to those in mafia hierarchy. Mamas are taking the position of caporegime, while sisters are the caporegime's soldier (also known as soldato) assigned by either the underboss (grandma) or the boss/don (unknown position Peter Ratri belongs to), while consigliere's position is held by Legravalima.
