Age: 11
Height: 145cm
Identification Number: 63194
Blood Type: O
Origin: GF (Grace Field)
Academic Ability: Full score (perfect score), slightly below Norman and Ray
Details: The eldest of the GF (Grace Field) House, who cares deeply about her family.

She always thinks about her family and loves and adores Mama, Isabella.

She has an innocent and childlike personality, but on the other hand, her tendency to prioritize her friends over herself sometimes leads her to shoulder everything alone, which is a flaw. However, she also has the inner strength to see things through once she sets her mind to it.

She has excellent athletic ability and is good at physical activities. In tests, she made mistakes at first, but gradually became able to get perfect scores under Ray's guidance, and in recent years she has been a top scorer with perfect scores every day alongside Ray and Norman.

First-person pronoun: Watashi
Bright and clear voice: Usually childlike, energetic, and straightforward in tone. Emotions are direct: When happy, she rejoices wholeheartedly; when angry, she gets genuinely angry—an expressive way of speaking.
Strong will: In moments of crisis to protect her friends, her voice becomes powerful and serious beyond what you'd expect from a child.

Identification Number: 81194
Blood Type: AB
Origin: GF (Grace Field)
Academic Ability: Full score (perfect score), above Emma, below Norman
Details: The only child among the group who can match wits with Norman. He is often seen reading books.

He is actually the "spy" who was connected to Isabella.

Moreover, he wasn't a makeshift spy for this escape—Ray had been a spy for a long time and had known the truth about this house long before.

However, in truth, Ray was acting as Isabella's spy in order to prepare for this escape.

Blood Type: B
Origin: GF (Grace Field)
Academic Ability: Full score (perfect score), above Emma and Ray
Details: A gentle and kind-hearted boy. Left-handed.

He has never scored anything less than perfect since testing began at age 4.

He has feelings for Emma and has clearly told Ray that he loves her. To fulfill her wish, he takes on the reckless challenge of "escaping with everyone."

Age: 10
Height: 155cm
Identification Number: 16194
Blood Type: O
Origin: GF (Grace Field)
Academic Ability: Frequently earns full scores. Below the perfect-score trio.
Details: He has a bright and competitive personality, but his weakness is "jumping to conclusions." He has a talent for pickpocketing, and he once used it to steal the key to Mama's secret room from her.

During Emma and the others' escape plan, he was initially told they were "fleeing from human trafficking," but later learned of the existence of demons and the truth of the House, and joined the escape team.

Age: 10
Height: 138cm
Identification Number: 65194
Origin: GF (Grace Field)
Blood Type: A
Details: She wears distinctive large round glasses and has a serious, shy personality, but also possesses a strong will.

The older girls in the House are assigned to take care of the younger children, and she gets along well with Emma, who shares the same duty.

Like Don, she is brought into the escape plan after Ray.

She is interested in fashion and laments that the clothes provided by the House are all white.

Her grades are the only ones in the 200-point range, second only to the top three eldest children.

Though she doesn't match Norman, she is a talented girl with excellent insight and calm thinking.

Name: Isabella
Age: 31
Height: 170cm
Identification Number: 73584
Origin: GF
Details: She never shows her emotions. She has an unyielding spirit and is a mother who always wishes for the happiness of the children.

She is the caretaker (Mama) who manages the human farm (plant) as a cold-hearted subordinate of the demons that feed on the children's brains.

As a Mama, she is extremely capable, and the food children from her plant are treated as high-quality goods.
One day, she commits the blunder of being seen by Emma and Norman as she ships out Connie—officially said to have "found adoptive parents"—to the grotesque demons, but Isabella wishes to continue the shipments while maintaining the current management system, and does not report this fact to her superiors.
