Anna is a nine-year-old orphan at Grace Field House Plant 3, born on April 25, 2036. She has fair skin, light blue eyes, and long blonde hair initially styled in twin braids. Her identification number, 48194, is tattooed on her neck. She wears the standard orphanage uniform: a white button-up shirt, skirt, and brown boots. Quiet, thoughtful, kind, and strong-willed, Anna deeply cherishes her siblings and displays fierce protectiveness and a willingness to sacrifice for their safety. After learning the truth about Grace Field from Don and Gilda, she joins the escape plan, sewing ropes for zip-lining and cutting her braids to shoulder-length to provide hair for a decoy body. She later wears her shortened hair in pigtails or a ponytail. During the escape in January 2046, she disables tracking devices, retrieves supplies, and treats injuries, including bandaging Emma and Ray’s ears after transmitter removal. She flees into the wilderness with fourteen other children. In the Promised Forest, she faces wild demon threats until being rescued by the demon Mujika, who teaches survival skills. Anna continues applying her medical knowledge, tending to wounds. After finding shelter, she chronicles daily life in a diary, documenting activities like foraging and gardening. When the shelter is attacked, the group flees again, finding temporary refuge near a demon village. Reunited with Norman, Anna supports Emma’s plan for a peaceful resolution with demons. She later participates in a mission to rescue younger siblings left at Grace Field, helping hack the orphanage network. She hones significant medical proficiency during her studies, learning to prepare remedies and handle emergencies. Ultimately reaching the human world, Anna celebrates her twelfth birthday and reunites with her surviving family.
