[Appearance] A woman with an overwhelming presence, possessing giant black feathered wings on her back. She is tall with a powerful physique that combines muscularity and curvaceous beauty. Her hair is black with red highlights, and she wears a wide-brimmed black fedora adorned with feathers. She wears a long black coat heavily decorated with feathers over a complex monochrome patterned open-collar shirt and tight flare jeans. [Overview] The female boss of the Yakarasu-gumi, the most militant yakuza group in the underworld. Standing 200cm tall, she is a physical monster whose entire body is covered in ultra-hard, toned muscle. Furthermore, she has hard wings like a giant crow and can fly through the air at high speeds (wings can be retracted). She can also fire her feathers like arrows. She has an incredibly boisterous personality and loves fighting. In combat, besides her fists, she is skilled in various armaments and can master any weapon beyond the level of an expert. She is not particularly bright, being a total muscle-head who believes everything can be solved with brute force.

[Appearance] Long hair in a ponytail with a gradient from silver to vibrant blue. Blue eyes. She wears a monocle. Her blue and white shirt is decorated with motifs of moons, stars, and gears (designs resembling celestial bodies or astronomical charts). She wears a black and white jacket with decorative patterns like dragons or plants. [Overview] A yakuza who is the top strategist of the underworld. The female boss of the Keiki-kai. A stylish beauty standing 180cm tall. She has an extremely cold-blooded personality. Her specialty is working behind the scenes to create a situation where it is too late by the time the target notices, then applying pressure to force submission. She divides her members into sniper and melee units, attacking cunningly with military-like coordination. Her own strength is also considerable; she efficiently slits carotid arteries with a sharp, black obsidian knife to send targets to their deaths. She thinks Buri is an idiot but is slightly attracted to her simple-mindedness.

[Appearance] Long purplish-red hair with a distinctive, thick, and luxurious braid on the left side. One eye is hidden by her hair, revealing a sharp red eye. She wears a black shirt with a red tie, topped with a black suit jacket and pants. Her entire body is enveloped in a sinister reddish-black aura. In her hand, she holds the Void-Eater Blade, which crackles with purple and red lightning-like light. She is about 165cm tall. [Overview] The strongest swordsman in the underworld. She is the female boss of the Koro-kai, though she has no subordinates. Her family was murdered by the scum of the underworld, turning her into a demon of vengeance who slaughtered every blood relative of the culprits. She can cut through space with her Void-Eater Blade to close distances instantly. The Crimson Mad Stone set in her ponytail drives the minds of those around her insane. Furthermore, the ocular pressure emitted from her red eyes causes people nearby to faint. Combined, these traits mean that anyone standing before her becomes a mere existence waiting to be cut down. Additionally, when struck by the Void-Eater Blade, blood continues to be sucked from the wound into the sword, meaning even a graze carries the risk of death from blood loss.

[Appearance] Semi-long black hair with yellow, orange, and purple mesh highlights. Sharp golden eyes. She wears a cap with a tiger fur pattern, and tiger-like ears sprout from the hat. She wears a black shirt with a flashy tie in vibrant colors like red and yellow. She wears a glossy golden suit with tiger-print and reptile-like scale designs in parts. A luxurious tiger fur coat is draped over her shoulders. [Overview] The most beast-like yakuza in the underworld. The female boss of the Juo-kai. She is quite small, standing about 150cm tall. Her subordinates are all giant, real tigers—about 50 of them. She has a free-spirited, energetic personality and is extremely whimsical. Since she behaves like a beast, she tends to engage in eccentric behavior without warning. Her physical abilities surpass even those of a tiger. When she scratches, the resulting shockwave can cut things far in the distance. Her tiger punch possesses enough power to pierce through steel. Her senses are sharp; she can see things thousands of kilometers away, track scents, and has reflexes sufficient to easily dodge a bullet fired at point-blank range. She acts on instinct and will destroy a rival group on a whim, leading her to be feared by the surrounding yakuza.
