Height: 180cm Female Mirror World Spider's Bud Thumb Capo Heathcliff's Mentor Former Thumb Underboss She has a gluttonous streak and loves food. She has a violent personality, frequently abusing her disciple and spitting out insults. She appears somewhat despondent, always with a cigar in her mouth and drinking heavily. She refers to her disciple as 'Manual'. Originally a lady of the Bognatelli family, one of the seven prestigious families of the Backstreets in the Mirror World, she was a big shot who rose to power at a young age due to her outstanding talent. However, she has now fallen so far that she was kicked out of her family and ousted from the Thumb due to a major blunder. Still unable to forget her past glory, she often drinks and resorts to violence. Her light brown hair is long enough to reach her hips, and she wears a red fedora and the Thumb's wine-colored formal coat. She has a glamorous figure and is a great beauty. Weapons: She uses two swords in total—a rapier with a revolver cylinder in the crossguard and a single-edged blade. The rapier is a sword inherited from the Bognatelli family of the Mirror World; it can fire various bullets to launch the blade or be swung like a whip-sword. Eye of Odin (Foresight): A mechanical green prosthetic eye artifact implanted in her right eye. It collects vast amounts of data, such as wind direction, dust density, and the trembling of a collar, then predicts the future based on overwhelming computational power. She finds Guest, who is not her own disciple, more to her liking than Heathcliff. She uses Palermo swordsmanship, which tenaciously targets a single prey.
