Jasper

Jasper (ジャスパー) is a minor character of The Promised Neverland series. He is a four-year-old orphan who formerly resides in Grace Field House as one of the many foster children of Isabella.

History
Jasper was born in 2041 and sent to Plantation 3 a year later in 2042, growing up along with several other children.

Introduction Arc
Taking daily tests, playing a game of tag, eating scrumptious homemade food and having a good time – Jasper went through the same routine every day in Grace Field House. He was seen saying goodbye to Conny during her departure from the House, and he was caught in a game of tag by Krone.

Jailbreak Arc
Jasper continued to have a comfortable life at Grace Field, unaware of the things happening in the House and his oldest siblings.

On the night when the House burnt down, Jasper was seen expressing concern regarding the absence of his 15 older siblings. After Isabella failed to retrieve the older children, Jasper 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.

Appearance
Jasper is a young boy with fair skin and oval-shaped light green eyes. He has short, softly cropped pale green hair. Like all the other children at the orphanage, he wears the standard uniform— a white shirt and trousers along with plain brown shoes. His identification number, "04394", can be seen on the left side of his neck.

Personality
Jasper is described to be a sleepyhead. He also likes to play tag and hide-and-seek with the rest of his siblings.
