Anna

Anna (アンナ) is a 9-year-old orphan who formerly resided in the Grace Field House. She is a quiet but thoughtful and strong-willed girl who is brought into the escape plan alongside Nat, Thoma and Lannion after the truth of the orphanage is revealed.

After her success of escaping Grace Field alongside 14 other orphans, Anna now seeks to find William Minerva, whom she and her family believe can grant them the liberty to live a safe and peaceful life away from the demons.

Appearance
Anna is a young girl with fair skin, light blue eyes and a rather petite build. She has long, straight blonde hair tied into twin braids, laid on her shoulders. She later cut her hair to about shoulder-length to save Ray, after which she began tying her hair in two short pigtails at the back. Like all the other children at the orphanage, she wears the standard uniform— a shirt and skirt like the other girls and has brown shoes. She has her identification number, "48194", tattooed on the left side of her neck.

In the live-action movie, Anna's platinum blonde hair is changed to brown. She has assumingly been aged up and thus she has the appearance of a 14-year-old teenager. Despite the age increase, the live-action version of Anna still resembles her manga and anime counterparts, such as her signature twin braids.

Personality
Anna is shown to be a bright, gentle, and kind girl who loves her siblings dearly. She is very protective of them, cares for them deeply and would go great lengths to keep them safe. Anna is one of the children considered trustworthy by Emma, and her willingness to help despite the danger demonstrates her loyalty and bravery. Anna is more than willing to make sacrifices for the sake of her family, as seen when she cuts her hair off for Ray.

Introduction Arc
Anna was first seen studying alongside Ray in the library of the Grace Field House. A few days later, during a game of tag, she was caught by Krone along with Nat and Thoma.

Jailbreak Arc
It is revealed that Anna, along with Nat, Thoma, and Lani, was brought into the escape plan after Don and Gilda trusted them enough to hear in on a conversation of Krone revealing information about the truth of Grace Field. Including Anna, the number of children aware of the secret by that point was increased to nine, including the three oldest children Ray, Emma, and Norman. However, over the course of the next couple weeks, Anna, Nat, Thoma, and Lani all kept a low profile in order to ensure neither Krone or Isabella could figure out their awareness of the secret as well. During the two months after Norman's shipment, Anna and her allies got instructions from Emma on how to train the orphans for the upcoming escape. in particular, Anna and the other children who knew of the secret managed to convince seven other younger children including Dominic, Mark, Chris, Rossi, Yvette, Alicia, and Jemima to join in on the escape plan.

In January 2046, Anna assisted with the escape by cutting her hair braids for Emma with her plan to outwit Isabella by using it as part of a decoy body for Ray. Anna, along side Jemima, also took responsibility in sewing the ropes used in the ziplining phase of the escape. Once Emma started the fire, Anna and the others put on their running shoes, grabbed the supplies they gathered and stashed in the forest, disabled the tracking devices in their ears with Ray's hand-made device, and ran to the wall once Emma caught up with them. Anna also assisted in bandaging Emma and Ray's ears after they were forced to cut them off in order to dispose of their tracking devices in a fast manner. Anna and her siblings then escape from Grace Field by ziplining down into the forest on the other side of the large cliff, where they flee as fast as they can until they reach another cliff and witness the sunrise for their first day as free children.

Emma
Anna loves Emma like a sister and worries about her well-being when Emma puts herself in danger. Emma considers Anna trustworthy enough to allow her to listen in on the conversation she and Norman have with Krone, thus revealing the truth about their situation at Grace Field. Emma's faith in Anna proved to be valuable - as Anna was able to help with preparations leading up to the escape. During the two months that Emma was feigning defeat, Anna, along with several other children, secretly took orders from her and trained their siblings while slowly inducting them into the plan.

Ray
Anna cares for Ray deeply. While their initial interactions are somewhat scarce due to Ray's quiet and independent nature. Like all the other children, Ray considered Anna a potential burden to the escape plan and urged Emma and Norman to reconsider their stance on trying to escape with all the children at the house. Unbeknownst to Ray, however, Anna was already informed of the secret and contributing to the escape efforts. During this time, Emma also made Anna aware of Ray's plan to kill himself the morning of his birthday. Anna cut off her braids to help create a convincing decoy for Isabella, so that Ray's suicide attempt could be avoided and he could escape along with them. Ray seems shocked to see Emma presenting Anna's braids, as her long hair was her most identifiable feature. This is a sign of sacrifice in Japan, and this is a slight hint to the future feelings Anna will feel for Ray later on in the series.

Norman
Anna and Norman did not interact that much when they lived in the Grace Field House. Norman agreed with Emma's plan to bring Anna, along with the others, into the plan without Ray's knowledge. Anna was saddened to see Norman leaving to join his new "foster parents" later on.
