Sisters (Live Action)

Sisters (シスター, Shisutaa) is a title given to female humans who are aspiring to become Mamas. They are caretakers for orphans in the Premium Farms like Grace Field House. Sisters are former "orphans" 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. They need to keep up their hard work or they may also get killed. Girls born at the Premium Farms are given the choice to either die or train to become sisters if they lived to twelve years of age at their farm. When a girl is picked to train to be a mom/sister at Grace Field, they are sent off to train at Grace Field Headquarters and study what they have to do and know to keep a plant thriving. They are also given tips on how to take care of children, clean, sew, etc. We know this based on the various stereotypical "motherly" activities shown in both Krone and Isabella's training montage. The Sisters are supervised by a Grandma that chooses the top scorers to become Mamas. Most Sisters reside at Grace Field Headquarters for the rest of their lives. Their job includes preparing food and supplies that will be sent to the "orphans", caring for the zero to one year olds, and giving birth to more children to fill the "orphanages". They are never allowed to meet their children as they are taken away shortly after birth. Sometimes, when a Mama requests extra help, a Sister will be sent to live at one of the "orphanages" to assist the Mama in caring for the children.

Like all of the humans residing at Headquarters, they have chips in their chest that do not allow them to leave the farm. If they leave farm property, they are immediately killed using the chips implanted on their heart.

Appearance
The Sisters 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 mamas.

Trivia
Their Victorian-era maid dresses worn in both the show in manga by the sisters represent the everlasting service they must do in order to run from what seems like their own fate. They are supposed to feel like servants, doing whatever it takes to meet ends due. Or in their case, doing whatever it takes to avoid death. This creates all the young girls put in this situation to feel powerless and brain dead. As if their only purpose is to help the very farm that's enslaving them.
