A top-tier combatant of the "Mad Cartel," known by the alias "Faceless Mace." He wears grey and black hooded camouflage gear and a black gas mask reminiscent of a demon. His full face was revealed after his gas mask shattered. He has a handsome, unblemished face with a beauty mark under his right eye, longish brown hair parted slightly, and long hair tied back loosely. His eyes are a clear yellow. His height was later revealed to be 179cm, which is relatively short among the fifth generation. He is reminiscent of Tangtang, a former member of the Mad Cartel. He is unnervingly high-strung and treats killing people like a game. His catchphrases include "[Body Part/Object] + [Onomatopoeia]" and "Top Secret." While he spoke nonsensical lines in group illustrations, he is perfectly capable of normal conversation. As his alias suggests, he uses a mace as his primary weapon. His proficiency is extremely high, enough to inflict heavy damage via a surprise attack on Toshiro Moriwaka, who is exceptionally strong against trickery. He is well-versed in Savate and possesses high martial arts skills and physical ability. He shows formidable strength in close-quarters combat through powerful kicks and knives hidden in the toes of his boots. True to his appearance, he also excels at surprise attacks using poison gas, which he uses to slow down opponents and gain the upper hand in battle.

More demonic than a demon... a total madman who can slice a human into sashimi with a smile. A master of Praying Mantis Style who can reap lives with his strikes. For some reason, he claims to be the "underling of the legendary Yamato Sako" and constantly pesters him. Recently, he has been obsessed with shaving off enemies' hair from the front with a kitchen knife to make them look like defeated warriors. He is extremely weak to alcohol. A combat specialist of the Kyogoku-gumi. He is a madman who uses a unique fighting style combining Praying Mantis Style with a sashimi knife, earning him the alias "Moriwaka of the Sashimi Knife." He is also called the "Inevitable Disaster of the Kyogoku-gumi." A few months before the Tenkyo War broke out, he was under suspension for causing trouble, but his suspension was lifted to fill the gap left by Sosei Sagara, who died in battle against Sakutaro Iio. He has short light-brown hair and purple eyes without highlights, though they occasionally turn black. He wears an orange short-sleeved polo shirt and short chinos. He has a neutral, handsome, boyish face. As officially described, he is a "man like a boy." However, he frequently wears an eerie smile, making it clear he is not a sane human being. A master of Praying Mantis Style, a type of Chinese martial art. He approaches enemies with bizarre, mantis-like movements and carves up their bodies like fish with his signature sashimi knife.

A junior member who is treated as a toy by his senior, Moriwaka. A young member of the Kyogoku-gumi, in his second year at the time of his first appearance. He has short blonde hair and wears a black shirt with a red jacket and white cargo pants. His combat skills are quite respectable.
