Jin

Jin (ジン) is a minor character of The Promised Neverland. He is a two-year-old orphan from new type Mass Production Farm N°1. He was shipped out to Lambda 7214 to experimented on. Jin, along with his teammate, Hayato, are allies with William Minerva, who they admire and look up to.

Appearance
Jin is a boy of average height and build. He has brown eyes and spiky black and white hair pulled back into a short, high ponytail. The hair pulled back in the ponytail is white, while the rest is black. Jin is always seen wearing a bluish-black bandana that covers his nose and mouth. He often wears a short brown-colored hooded cloak with lacy ends as well as a black long-sleeved shirt under a orange-colored vest, black pants, gray gloves, black shoes and an owl pin. He has the build of a teenager as a result of the experiments performed on him. He also has Lambda's identifying brand tattooed onto the left side of his chest. Underneath the Lambda brand is a "01" brand from the Factory Farm he originally came from.

Personality
Jin is determined and fiercely loyal, specifically to Norman, as shown by his willingness to follow Norman's orders to kill Mujika.

History
Jin was born on October 10, 2045 at new type Mass Production Farm N°1. At some point, he was shipped out to be a test subject at Λ7214, which is where he gained his unusual abilities. The drugs that were given to him seemed to have caused him rapidly grow and mature, much like Hayato and Zazie. At some point in 2046, "Minerva" destroyed the facility and rescued all the children within, Jin included. Thereafter, he was brought to the Paradise Hideout like everyone else, developed deep respect towards his savior, and began working under him.

King of Paradise Arc
After the destruction of B06-32, the orphans from Grace Field and Goldy Pond are traveling through the forest. Emma, Ray, and Don sense a wild demon nearby, so they separate from the group and try to find it. However, when they find the pack of wild demons, they are surrounding two unknown humans. Emma exclaims that they need to save them, so she, Ray, and Don jump into action and swiftly kill the demons.

They then confront the two humans, who are very grateful and begin thanking them. The two then introduce themselves as Jin and Hayato. After Hayato notices Emma's farm identifier, he and Jin explain that they were looking for them under orders from William Minerva.

Jin and Hayato are then introduced to the rest of the group, who they immediately respect and admire. The two explain how they were saved by Minerva, and that Minerva asked them to look for the Grace Field escapees and bring them to their base.

Human World Arc
Upon arriving in the Human World, Jin is seen to be visibly worried and shocked about Emma's disappearance. Jin, along with the other children, agrees to search for Emma so they can reunite with her again. Over the next two years spent in the Human World, Jin began attending school. During spring 2049, he finally reunites with Emma again and cries tears of joy, even though she lost her memories.

Hayato
Jin and Hayato are good friends, and they are often seen by each other's sides. They try to help each other out when they are in danger.

Norman
Jin—along with hundreds of other children—was rescued from Lambda 7214 by Norman. He respects Norman and often takes orders from him.

Weaponry
Jin seems to be skilled in using a spear, and it appears to be his weapon of choice.

Speed
Just like Hayato, Jin has super speed and can run in such manners that no normal human can. This is shown when he could quickly carry the news of Adam having possible cure to seizures to the shelter. This is revealed to be something he got from being experimented in Λ7214.
