ガァプ

Gaap is 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 gives 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. [From Wikipedia]
