Sarah

Sarah (サラ), who is dubbed as Grandmother (祖母)undefined is a villain of The Promised Neverland. She is a high ranking human at the Grace Field House, serving as its leader, who considers Isabella as one of her pawns.

Introduction Arc
On 17 October 2045, Isabella contacted the demons via the telecommunication device in Grace Field House's secret room. Isabella notified the Premium Farm's headquarters that everything in her House is fine. Isabella's communication was soon abrupted and cut to Sarah. Sarah notified Isabella the message she received from on how the latter wishes Isabella to ship out three of her orphans (Emma, Norman and Ray) from her planation soon. The Grandmother added on how the other 3 premium farms, Glory Bell, Goodwill Ridge and Grand Valley did not produce any worthy orphans for the demons to feast on, and thus could only depend on Isabella and Grace Field House to do so.undefinedundefined

Jailbreak Arc
In order to get rid of Krone, Isabella got Sarah to write a fake letter about how Krone is promoted to become a Mama, and how she is assigned to one of the other three premium farms. Suspicious of her sudden promotion, Krone wrote a note in regards to how several older orphans in Grace Field House knew the truth and secrets behind the orpahange. When Krone passed the note to Sarah at the gates, Sarah did not believe Krone, and said even if Krone's contents in her note were true, Isabella would be able to cease the orphans by herself. A brief flashback of Sarah waving to a young Isabella was shown as the former explained how Isabella can solve the situation just like how she did in the past. Before ending the conversation, Sarah whispered into Krone's ear on how she is an obstacle for Isabella, and how she is no where as capable as she is in replacing her abilities. Sarah soon walked away, as a demon under her command lurked from the shadows and pierce Krone with a Vida, ending her life.undefinedundefined

On 15 January 2046, when Grace Field House was burnt down by the fire which Emma started, Isabella was called back to the gates and received a violent scolding from Sarah, who was immensely upset on the 15 orphans that have escaped, two of which are the premium quality goods (Emma and Ray) Isabella was supposed to produce for. Sarah addressed Isabella by her plantation number instead of her actual name, and remarked on how due to her mistake, all of the better quality good are gone. Sarah asked Isabella on why would she do such a thing, especially since she is someone whom she placed her trust on. Isabella replied how it was entirely her own fault.undefinedundefined
