Black-haired boy

Black-haired boy is a placeholder name for an unnamed boy living at Grace Field House. He is one of the minor character of The Promised Neverland. He is a two-year-old orphan who formerly resided at Grace Field House Plant 3 as one of the many foster children of Isabella. He only appears in the anime, replacing Milly from the manga. Due to his age, he is considered to be one of the house's "low-quality goods".

After Grace Field House Plant 3 burnt down, he was moved to a different plantation at Grace Field, albeit not the same one as Phil.

History
He is a two-year-old orphan born at Grace Field in 2043 and sent to Plantation 3 a year later in 2044, growing up along with several other children under the parental care of Isabella. He sleeps in Isabella's room and was left behind with the younger children at Grace Field House, while the children over five years old made their escape. He now resides at a different plantation at Grace Field after the Grace Field House Plant 3 was burnt down.

Appearance
He has short black hair parted on the left side and slanted eyes. He wears the standard Grace Field uniform- a plain white long sleeved button-up shirt and white pants along with brown boots. His identification number is tattooed on the left side of his neck.

Personality
Not much of his personality is shown, but he appears to be an innocent, happy, and typical two-year-old who loves his family and enjoys playing tag and hide-and-seek with his siblings.

Introduction Arc
Taking daily tests, playing a game of tag and hide-and-seek, eating scrumptious homemade food and having a good time – he went through the same routine every day at Grace Field House.

Jailbreak Arc
On the night when the House burnt down, he was seen expressing concern regarding the absence of his fifteen older siblings. After Isabella failed to retrieve the older children, he was seen sleeping with his other siblings who were left behind, being cared for by Isabella. Emma promises that she will come back within two years to rescue her siblings from Grace Field.

Cuvitidala Arc
Two months after the escape and Grace Field House Plant 3 burnt down, it is revealed that he was transferred to one of the other plantations at Grace Field, albeit not the same one as Phil.

Return to Grace Field Arc
After getting the word that all the farms are to be abolished, Emma returns to Grace Field House to get him and the others.

Emma, Norman and Ray
Emma and Norman have a deep regard for him, as he is a part of their "family". Upon learning that all of her sibling that had been shipped out were dead, Emma and Norman vow to escape with all of their younger siblings, despite most of them being under the age of five. Ray, however, is more skeptical of their plan and considers everyone other than Don and Gilda to be burdens to their escape plan.

Despite this, Ray really does care about his younger siblings, but believing that escaping with everyone was impossible, he had emotionally detached from them over the years and tried to avoid becoming too close to them so that he would not be as sad when they were inevitably killed. After Norman successfully came up with a plan to escape without sacrificing anyone, Ray admitted defeat and finally joined Emma in vowing to not leave anyone behind. They ultimately decided to escape with all of their siblings over the age of five and return to rescue their younger siblings within two years, before they were old enough to be shipped out.

Isabella
He did not know the real intentions of his caretaker, Isabella, and loved her very much as she were his real mother. After fifteen of his older siblings escaped from Grace Field, he was sent to a different plantation at Grace Field with a new mother. Still not knowing the truth of the orphanage, it is assumed he loved his new caretaker just as much as Isabella.

Grace Field Escapees
He and his older siblings loved each other very much. After fifteen of his older siblings escaped from Grace Field and Plant 3 burned down, he was seen expressing concern of their whereabouts. he did not know the truth of the orphanage nor did he know that his older siblings had actually escaped, and after being relocated to a different plantation at Grace Field, he was told that his fifteen older siblings had been sent to live with foster families. Despite leaving him behind, the Grace Field Escapees vowed to return within two years to rescue him and their other younger siblings before they could be shipped out.

Trivia

 * He has an identical appearance to the two-year old Dark brown-haired boy, but with black hair and his hair is parted on the opposite side. As a result, it is highly possible that they could be twins.
