An executive-level member of the X faction. Male. 25 years old. Standing 179cm and weighing 80kg. He usually wears baggy clothes, so his physique isn't obvious, but he has an incredibly well-built body when he takes his shirt off. His birthday is November 27th. He has a chic, cold appearance with silver hair slicked back and red paint around his eyes. His irises are red, contrasting with his boss Uzuki Kei's blue eyes. He wears small, black, square-shaped earrings. He is a battle maniac who enjoys fighting like a game. However, unlike other talkative and hot-blooded battle maniac characters, he is extremely calm and cool-headed when fighting. He shows no change in expression even in life-or-death situations and never loses his composure in startling moments. Not just in battle, but in daily life, he is a man of few words, shows little emotion, and is generally indifferent to everything. However, he does smile with joy when he encounters a strong opponent in combat. While he may seem cold and heartless, he shows a subtle, warm affection for his comrades despite his indifferent attitude. He was raised in Al-Qamar, a secret nursing facility directly managed by the JAA, and was used as a bargaining chip by Asaki Sei to blackmail Uzuki Kei. Seeing how he remained stoic and calm even when being unilaterally beaten by Asaki Sei, it is assumed he was constantly subjected to violence. He always keeps bandages wrapped around his arms and weapon. The reason is unknown. He seems to enjoy eating. His main weapon is a steel mace. It looks somewhat like a long tonkatsu hammer and has a laser function at the tip for shooting. However, he doesn't prefer sniping, so he rarely uses that feature. His hobbies are gaming and sleeping.

The boss of the X faction. Known by the alias X (Slur). Male. 182cm, 73kg, 28 years old. Birthday is October 14th. Given his low weight relative to his height, he is presumed to have a lean, muscular build. The title 'X (Slur)' wasn't one he chose for himself; it was a nickname given by the JAA because he left an X mark at every crime scene. Uzuki liked it, so he began calling himself X (Slur). Because Uzuki wants to deny his past self, he prefers the new alias over his real name. He is officially handsome. His eye color is a vivid blue, contrasting with the red eyes of his close Al-Qamar member, Gaku. He wears his wavy white hair in a 5:5 middle part. With bangs reaching halfway down his eyes and pale skin, he exudes a dark, handsome aura. Before becoming an adult, he was indecisive and naive, even trying to avoid killing when it was inevitable. However, due to a certain incident, he transformed into a cold-blooded and ruthless killer. Yet, seeing how he cherishes his Al-Qamar comrades as his own family, it's clear his original nature was kind. Ultimately, his personality was twisted by a tragic past, and it is heartbreaking that trauma turned him into the very person he never wanted to be. His way of speaking is kind and gentle. Like Gaku, Uzuki was born and raised in Al-Qamar. He is a top-tier combatant based on his fundamental abilities alone. His main weapon is a steel whip. The cord is lined with multiple blades and is over 12 meters long. He operates it at such high speeds that his movements are impossible to read. He is terrible at drawing. His hobby is reading.

A member of the X faction. Male. 26 years old. He weighs 300kg at 184cm due to his mechanically modified body. Birthday is July 19th. He wears a reindeer head over a suit and tie. He always uses a kind, polite tone and formal speech, even toward enemies; though he may say harsh things, he maintains his formal register until the end. He often uses formal speech even in his internal monologues. However, informal speech may slip out when he is agitated. He is the most extreme case of someone who cannot stand injustice; at age 17, he once left people bloody for harassing a stray cat. While others condemned him, Uzuki was the only one who praised and protected him, leading Kashima to admire and remain loyal to him. Analyzing his battles proves he is undeniably strong. His entire body is wrapped in wire and boasts powerful durability. With an artificial skeleton, he feels no pain and can snap his neck back into place even if it's turned 180 degrees. He has survived fatal wounds and dismemberment that would have killed anyone instantly. His tenacity is such that he remains perfectly alive even when only his head and part of his chest remain. Furthermore, 70% of his body has been turned into weaponry through science, featuring a wide variety of armaments: Wire + Grappling Hook + Live Ammo Gun (Right Arm) Blade Swarm (Left Arm) Laser Gun (Mouth) Explosive Energy Gun (Abdomen) Grenade Storage (Back, Mouth) He is highly skilled in medicine. He once successfully reattached Gaku's severed arm. He likes coffee and hates Christmas. His hobby is modification.
