Simon

Simon (サイモン) is a minor character of The Promised Neverland. He was a friend and the new adoptive brother of Phil at an unknown plantation at Grace Field House before being shipped off.

Cuvitidala Arc
Simon is first seen at Grace Field at an unknown plantation Phil got sent to after his previous home burned down. Simon was seen playing outside with Jackie, Helen, Carol and Phil and it seems like that he cares about his siblings a lot. In 2046, he was shipped-out by his caretaker Yukko and killed by the demons afterward.

Appearance
Simon appeared to be a cheerful boy. He wore the standard Grace Field uniform and always appeared to be smiling a lot. What also stood out were his thick eyebrows and rather long, wavy blond hair.

Personality
Simon was a very energetic, playful and cheerful boy who loved his siblings deeply. Phil described Simon to be a lot like Don because of his playful personality.

Phil
Phil and Simon shared a great bond with each other. This was proved when Phil was absolutely heartbroken when he knew what was coming for Simon after he was shipped out.

Yukko
Simon did not know the real intentions of his caretaker and therefore it is assumed that he loved her very much, up until his death.
