Emma is the main protagonist of the manga series The Promised Neverland, created by Kaiu Shirai and Posuka Demizu. Emma is an 11-year-old girl living at Grace Field House. She consistently gets perfect scores on her daily exams. She is the life of the party and a quick learner. She is known for her ample optimism as well as her capable athleticism, and she can also be crazy at times. Upon discovering the truth of the orphanage, Emma teams up with Norman and Ray to escape the house. She loves her family more than anything and her strong sense of selflessness insists that everyone escape together, even if most of their siblings are below 6 years old, an aim which Ray deems crazy and plain reckless.
