Helena was an orphan 1 year older than Ray, Emma and Norman who formerly resided at Grace Field House Plant 3 as one of the many foster children of Isabella before she was shipped out. During her time at the house, she was considered the best artist out of all the children, and especially loved drawing optical illusions.
Helena is a rather tall girl. She has a smiling face, big eyes and long light brown hair tied into a single braid in the back. The number "70194" is tattooed on the left side of her neck.
Not many things are said about her, but it's known that she is a quiet, thoughtful and often pensive child, alone in her corner. Despite this, she is deeply attached to her siblings, and doesn't hesitate to play or joke with them.
- Helena made a cameo in The Promised Neverland anime series' first and second ending theme songs, Zettai Zetsumei and Lamp, respectively. Helena was the girl with brown hair praying at the dining table in Grace field's cafeteria along with Isabella and several other orphans.
