The 33rd highest ranking earl of hell named after the demon of the same name. She is a curly-haired woman who wears a red dress and a hat with a pink bow. Quite flamboyant, Gaap loves to tease people and give people random nicknames by shortening their names ("Riiche" for Beatrice, "Lia" for Virgilia, etc.). She is one of Beatrice's friends, though she is greatly disliked by Virgilia. She draws power from the Abyss to summon holes that can lead anywhere, although there are limits. In battle, particularly against George in Alliance of the Golden Witch, she uses a combination of these portals and various kicks that stab with her sharp heels, overwhelming her opponent and keeping them from moving as they emerge from the portal in mid-air.

Spoiler

From an anti-fantasy perspective, Gaap was created as an imaginary friend by Yasu as a personification of their habit to lose things. Instead of being called Gaap, at this point in time she was called Beatrice. Yasu envisioned Beatrice as the reason why their keys would always disappear and earned her help in playing pranks on servants. At some point, Yasu created a new design for Beatrice and made the original appearance the demon Gaap.
