A high-ranking member of the X Order. Male. 25 years old. Height 179cm, weight 80kg. He usually wears baggy clothes, so his physique isn't obvious, but he is in incredibly good shape when he takes his shirt off. Birthday is November 27. He has a chic, cold appearance with silver hair swept back and red makeup around his eyes. His irises are red, contrasting with the blue eyes of his boss, Uzuki Kei. He wears small, black square earrings. A battle maniac who enjoys fighting like a game. However, unlike other talkative or hot-blooded battle maniacs, 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, rarely changes his expression, and is generally indifferent to everything. However, he smiles with joy when he encounters a strong opponent in combat. While he may seem cold and heartless, he occasionally shows a subtle, warm affection for his comrades despite his indifferent attitude. He was raised in Al-Kamar, a secret welfare facility directly managed by the JAA, and was used as a pawn by Asaki Sei to blackmail Uzuki Kei. Judging by his calm expression and tone when he was shown being unilaterally beaten by Asaki Sei, as if it were a natural occurrence, it is assumed he was constantly subjected to violence. He always keeps bandages wrapped around his arms and his weapon. The reason is unknown. He seems to like eating. His main weapon is an iron mace. For some reason, it looks 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 Order. Known by the alias X (Slur). Male. Height 182cm, weight 73kg. 28 years old. Birthday is October 14. Given his low weight for his height, he is assumed to have a lean, muscular build. The title X (Slur) wasn't one he chose; 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 he wants to deny his past self, he prefers the new alias over his real name. He is officially handsome. His eye color is a deep blue, contrasting with the red eyes of his close Al-Kamar member, Gaku. He wears his wavy white hair in a 5:5 middle part. His bangs reach halfway down his eyes, and his pale skin gives him a dark, handsome aura. Before becoming an adult, he showed indecisive and naive traits, such as trying to avoid killing even when it was inevitable. However, due to a certain incident, he transformed into a cold-blooded individual who is ruthless about killing. Yet, seeing how he considers his Al-Kamar comrades as family and cherishes them, it's clear his original nature is kind. Ultimately, his personality was twisted by a tragic past, and it is tragic that he became the very thing his past self never wanted to be. Like Gaku, Uzuki was born and raised in Al-Kamar. In terms of basic ability alone, he is a top-tier powerhouse. His main weapon is a steel whip. The cord is attached with multiple blades and is over 12m long. He operates it at such high speeds that his movements are impossible to read. He is terrible at drawing. His hobby is reading.

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 incredible durability. With an artificial skeleton, he feels no pain and can snap his neck back into place even if it's turned 180 degrees.
