Lady Bayon

The subject's husband is referred to as Bayon II in this article to avoid any confusion with the latter's father and this subject's father-in-law, Bayon.

Lady Bayon (バイヨン夫人) is a minor character of The Promised Neverland. She was the wife of Bayon II and a member of the Five Regent Families.

Appearance
Lady Bayon is a slender white-colored demon who wore a unique demon mask, which instead of having two vertically placed eye holes and horns on the forehead like most demon masks, has a single vertical gap in the center and no horns. She had what seemed to be large, droopy ears with a light-colored ponytail that reached to her back. The frontal portion of her hair was tied into loose twin tails, which rested on her shoulders. She donned a baggy, feet-length dress that covered her high heels.

Cuvitidala Arc
At the train station in Bayon II's territory, Lady Bayon held onto her child's hand as she brought her child to board the train. Lady Bayon responded to her child that they are traveling to the Royal Capital where the Tifari awaits, and how Bayon II and the lords of the other clans are there as well.

Imperial Capital Battle Arc
It was later revealed that she had been consumed by a member of the Geelan clan, who then took on her identity and secretly infiltrated the Royal Capital.
