Scarlet

Scarlet (スカーレット, Skāretto) is a character in the one-shot chapter A Mother's Determination. Born and raised on an unknown plantation at Grace Field House, Scarlet now works as a Sister at Grace Field Headquarters. Due to her age, Scarlet is considered to be one of the house's "premium quality goods".

History
Scarlet was born and raised as an orphan at Grace Field House at an unknown plantation. At the age of twelve she was shipped out and began training to become a Sister at Grace Field Headquarters.

Appearance
Scarlet has dark skin, black eyes, and short black hair styled into a bob with a white hairband. As a child, she wore the standard Grace Field uniform- a plain white long sleeved button-up shirt and white skirt along with brown boots. As an adult, she wore the standard orphanage uniform made for the plantations' Sisters, which consists of a black dress with a white blouse underneath it and a white apron over it. Her identification number is tattooed on the left side of her neck.

Personality
Scarlet is said to be once affectionate but when she turned twelve, her boundaries changed, her specialties are her swiftness and the ability to closing off her emotions, refusing to be attached helped her climbing up in a position of a sister. She is also very intelligent, diligent, and dutiful, as she is one of the sisters closest to becoming a Mama and she presumably got perfect test scores as a child. However, like all of the Sisters, Scarlet constantly lives in fear. She believes the only way to get a slightly better life for herself is to compete with the other Sisters and bring them down in hopes of taking their positions and making herself look better in the eyes of Grandma and the Demons. She is very depressed and unhappy with her life, but she manages to mask her despair in order to get her job done.

Promised Forest Arc
In February 2046, a month after fifteen orphans escaped from Grace Field and Isabella was promoted to Grandma, four sisters, Matilda, Scarlet, Sienna, and Jessica are jealous of Isabella's new position and decided to team up to take her down. They decided to frame Isabella by forging suspicious communication data and planting it in Isabella's room. Then they plan to start a rumor about Isabella possessing the data so that when the Demons search Isabella's room and find the data, she will get blamed for it. While Scarlet and Sienna begin spreading the rumor amongst the other sisters, Jessica keeps watch and informs Matilda via a walkie-talkie that Isabella has left her room and it is all clear for Matilda to go in to plant the fake documents. However, Isabella is one step ahead of them and as Matilda enters the room she is shocked to find Isabella inside having tea with Sienna, Scarlet and Jessica.

All four sisters were visibly petrified that they had been caught and their fear only intensifies when Isabella takes the documents from Matilda and revealed that she already knew their plan. Fully expecting Isabella to report them to the Demons, the four sisters are shocked when Isabella instead tells them that she plans to destroy Grace Field and asks for their help in doing so. The sisters do not believe her at first, but Isabella reminds them that there is no true way to achieve a happy life at the farm. Even the Mamas and Grandma, the positions all the sisters strive for, live in fear, have to compete with each other, and are viewed as nothing more than food by the Demons. Isabella also tells them that she had been raising their children and Plant 3 and that they are alive with some of them being among the escapees. The sisters agree to join her, but only if Isabella gives them a collateral that ensures she will not betray them if the plan fails. Isabella agrees and gives them the note written by Ray which Krone found and gave to Sarah in an attempt to bring Isabella down. The note is a goodbye letter from Ray to Isabella which reveals Ray knows he is Isabella's biological son. That way if Isabella betrays the sisters, they can show the Demons the note and say Isabella let her children escape because one of them was her biological son.

Return to Grace Field Arc
On November 13, 2047, just before Emma and the other escapees returned the Grace Field, Isabella along with Matilda, Jessica, Scarlet, and Sienna decide to finally approach all of the other sisters with their plan to betray the Demons and Peter Ratri. Isabella uses the same tactics the get the other sisters to join them. Later that day, when Ratri has the escapees cornered, Isabella and the other sisters turn their guns on Ratri in order to save the children.

Human World Arc
Later in the Human World, Matilda, Jessica, Scarlet, and Sienna visit Isabella's grave and leave flowers by her gravestone. They thank Isabella for her sacrifice and tell her that because of her efforts, they are happy now.

Isabella
She is shown to be saying that it is an honor working under her but then burst in anger saying that it was unfair for her to be alive after the four's hard work in aiming to become a Grandma, even though she hates Isabella she is shown to believe in her and at the end she has lost all the hatred towards her and is grateful towards her for standing up and destroying the farms.

Jessica, Matilda, and Sienna
Scarlet is friends with Jessica, Matilda, and Sienna, and after Isabella became Grandma, they decided to team up to bring Isabella down. However, they could never fully trust each other because the Sisters were always competing with each other and could never know when someone might betray them to help themselves. But after Isabella recruits them to help her bring down Grace Field, they seemed to develop a closer and more trustworthy relationship with each other. Their relationship seems to improve even more after going to live in the Human World, as they no longer have to compete with each other and can just be friends normally.
