Jin

Jin (ジン) is a minor character of The Promised Neverland. He is a 2-year-old orphan from an unknown Factory Farm. 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.

History
Jin was born on October 10, 2045 at an unknown Factory Farm. 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 him rapidly grow and mature, much like 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.

Appearance
Jin is a boy of average height and build. He has spiky hair pulled back into a short, high ponytail. The hair pulled back in the ponytail is white, while the rest is black.
