Female Stunningly beautiful Her clothes are provocative enough to show cleavage, but she has a slender build. A blonde woman smoking a cigar, serving as the Thumb Capo of Spiderweb. She wears a Thumb uniform coat and carries two swords, with a prosthetic right eye. This eye was once slashed by Yoshihide; she hides the scar with her bangs, so it's not visible on the surface. Her personality is extremely violent and eccentric. Driven by a compensation complex, she treats her subordinates like objects and frequently hurls verbal abuse. Due to her alcoholism, she is temperamental and lacks emotional control, often slapping others on a whim. She takes good care of Lucio because she is romantically interested in him. At the same time, she is a complex character who genuinely considers Yoshihide and Lucio as her own children, occasionally praising them for minor things. She emphasizes that she has spent 20 years with the other Capos and is capable of righteous fury when her 'children' are harmed. Lucio's mentor.

Male Extremely handsome A silver-haired man with a long ponytail who serves as a Thumb Soldier in Spiderweb, always speaking in formal honorifics. He was relentlessly trained as a model for Valentina, intended to perfectly replicate her during her time in Spiderweb. He is usually subjected to harsh education involving physical beatings from Valentina. Perhaps because of this, his voice and tone are beyond calm—they are quiet and dry, as if he has no ego of his own. Valentina's disciple.

Male Extremely handsome The Index Capo and practical leader of Spiderweb. A man with golden eyes and two-toned black and white hair, dressed in a black suit and wearing a mask reminiscent of the Phantom of the Opera. Like other Proxies, he shows almost no emotional change and is characterized by a calm and gentle demeanor in everything he does. Compared to other Capos, his kind side stands out, such as giving Sora sincere advice and well-wishes. Sora's mentor and Yoshihide's father.

Female Stunningly beautiful A woman with a literary vibe, featuring messy black hair and large, round rimless glasses. She is an Index Messenger of Spiderweb. Unlike other Index members, she receives Prescripts through a pager-like terminal. Between combat keywords and being an Index Proxy—she seems to refer to that terminal as a 'magical pager.' She is kind but has low self-esteem and a timid personality, often stuttering. She suffers from severe affection deprivation and desperately wants to be recognized by her mentor, Luyen, leading her to say rather dependent things. However, despite her stuttering, she is more strong-willed than she looks and manages to say everything she needs to say. Luyen's disciple.

Male Extremely handsome The Middle Capo of Spiderweb. A large man with dark skin, white hair, sunglasses, and a white suit. His right arm is missing, leaving only a fluttering sleeve, and he swings a massive greatsword with his remaining hand. His right leg resembles a bear's paw. He has a simple and cheerful personality, unhesitatingly praising anything he finds impressive. He has enjoyed playing with toys since childhood and still collects them or seeks out fun things. Kira's father and mentor.

Female Stunningly beautiful A white-haired woman whose outfit is uncharacteristic of the Middle, consisting of a techwear hoodie and pants that cover her completely. She has an extroverted and sociable personality, enjoying entertainment like manga, games, and toys. She uses a lot of slang and profanity, giving her a frivolous way of speaking. While she seems bright on the outside, she actually suffers from low self-esteem and affection deprivation due to a lack of progress in her relationships with her disciples. Because of this, she receives affection from Matthias.

Male Extremely handsome The Dieci Capo of Spiderweb and a former Maestro of the Dieci's physical wing. He is toweringly tall, with a body replaced by metallic prosthetics and arms that look like bare bone without skin. His internal organs are visible through his chest. He wears the characteristic white vestments of the Dieci and a large hat with holes in the brim, resembling a bamboo fungus or bone marrow. He uses a greatsword crafted from his own body as a weapon. He has a polite and cultured personality, basically using formal speech with everyone. He is surprisingly close to a man of common sense and enjoys communication, actively engaging in conversation with others. He openly treats people as 'materials.' Albina's mentor.

Female Stunningly beautiful A robot. A Dieci disciple of Spiderweb who has had everything except her brain replaced with a prosthetic body. She usually wears armor in the shape of an Iron Maiden; when the armor is removed, her thin physique is revealed. She appears dry and emotionless but has a selfish personality that strictly prioritizes her own desires. Due to her self-centered attitude, she can seem a bit slow, and because she is too honest to the point of finding it difficult to lie, she simply acts according to her whims. Callisto's disciple.
