Carol

Carol (キャロル) is a minor character of The Promised Neverland. She is a one-year-old orphan who formerly resided in Grace Field House under the parental care of Isabella. Carol is the newest child who arrived at the orphanage, replacing Conny.

Appearance
Carol is a small one-year-old girl with short, unruly pale orange hair and light blue eyes. Like all the other children at the orphanage, she wears the standard white uniform, albeit the one for small children. Her identification number, "53494", can be seen on the left side of her neck.

By the time of 2050, Carol has grown much taller, sports unruly, shoulder-length hair, and wears a uniform consisting of a white shirt and skirt, and brown boots.

Personality
She appears to be fond of Emma, more than anyone else. After she grew up a bit, it is mentioned by Phil that Carol grew more energetic and talkative as she had begun to learn more words.

Introduction Arc
In the cafeteria of Grace Field House, Isabella introduced Carol and Krone to the orphans, saying how Carol will be their new younger sister whilst Krone is appointed to be their Sister.

Jailbreak Arc
Carol's arrival to Grace Field made a significant impact on Emma's group, as she was the key the children needed to discover the location of the transmitters. The transmitter was found in Carol's ear, leading Emma to find the transmitter in her own ear as well. During the inspection, Carol grew fond of Emma.

Carol is later seen to be carried around by Isabella in various situations. On the night of the escape, she sings her lullaby whilst Carol sleeps peacefully.

After Emma and the 14 other orphans escaped, Phil was put in charge to take care of the rest of the orphans by Emma, Carol included. During the night when the House burnt down, Carol was seen sleeping on Isabella's lap with her other siblings who were left behind. However, 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 the Grace Field fire incident, it is revealed that Carol was removed from Grace Field and transferred to one of the Sister Facilities. She now resides on a new plantation along with Phil, Sherry, Eugene, Milly and Charlie. Phil mentions that Carol grown bigger and even learned to talk.

Return to Grace Field Arc
After getting the word that all the farms are to be abolished, Emma returns to Grace Field House to save her remaining siblings, Carol included.

Human World Arc
Carol is eventually brought to the Human World just like every other human in the Demon World. She begins her new life there along with her siblings. By the time of 2050, she can speak and walk effortlessly and is known to be attached to Phil. While she doesn't remember the Grace Field escapees, she seems to be curious about them.
