Mark

Mark (マルク) is a 5-year-old orphan who formerly resided in the Grace Field House. Mark is considered as one of the house's "low-quality goods" and hence has average intelligence for his age. He was brought into the escape plan by Emma about two months after the truth of the orphanage was revealed.

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

Appearance
Mark is a young boy with a wide smile and round, light blue eyes. He has light brown hair which resembles a bowl-cut, with straight, evenly-cut bangs which cover his forehead. He also has an ahoge on the top of his head, which resembles the stem of a leaf. Like all the other children at the orphanage, he wears the standard Grace Field uniform— a white shirt and trousers along with plain brown shoes. His identification number, "79294", can be seen on the left side of his neck.

Personality
Mark is described as a boy who loves to eat. He is a cheerful and curious boy who wears his emotions on his sleeve. He cares about his siblings and is very protective of all of them. Like the rest of his younger siblings, he is also shown to be determined and eager to help out.

Introduction Arc
Taking daily tests, playing a game of tag, eating scrumptious homemade food and having a good time – Mark went through the same routine every day in Grace Field House, an orphanage he has been living in ever since he was born.

On October 12, 2045, he was seen playing with his siblings and was eventually caught by Norman in a game of tag. Standing alongside Naila, he also said goodbye to Conny who was leaving the orphanage.

When Naila got lost in the forest, Mark came up to Isabella, crying. He told her that he had tried searching for her but couldn't find her. Isabella later found her using the navigator, inadvertently revealing for the older children that she could track them.

Later, during another game of tag, he was caught by Krone. He was also seen participating in the training sessions under the disguise of playing.

Jailbreak Arc
As one of the youngest children, Mark was one of the last people recruited into the escape plan after hearing about the truth about the orphanage, the House, and Isabella. Mark and his siblings escape from Grace Field House on January 15, 2046.

Naila
Mark grew up with Naila ever since they grew up at Grace Field House. Out of all the children, Mark was the closest to Naila. They were always seen by each other's side, playing with each other, and helping each other out.

Grace Field Escapees
Mark gets along with the Grace Field Escapees, particularly the younger children, such as Alicia, Jemima, Yvette, Rossi, Dominic and Chris. They are often seen playing together, helping each other with chores and cheering for one another's accomplishments. He also has an attachment to the older kids, such as Emma and Ray.
