The ultimate cross-dressing hitman and pride of the Amou-gumi. He sets honey traps using his genius-level disguise abilities. After undergoing rigorous training under Noda's direction, he became so beautiful it seems like a divine prank. He possesses extremely high skill in quick-drawing firearms. A member of the Amou-gumi. One of Kotouge's seniors, he is known as "Kazuki the Cross-dressing Hitman," operating in the shadows with his natural beauty and mastery of disguise. When he was a low-ranking member in his early twenties, a girl at a brothel he was patrolling did his makeup as a prank. Hajime Noda happened to see him, which led to him being groomed into a cross-dressing hitman. Through subsequent elite training in feminine arts and conversation techniques to appeal to men, he acquired seduction skills capable of bringing down any man. Since then, he has excelled as a key asset in infiltration, assassinations, and luring operations by posing as a hostess or an ordinary woman. In combat, he is a highly trained marksman and meticulous professional who uses non-metallic assassination blades to bypass detectors. He has near-white silver hair, wisteria-colored eyes with a slight droop, and a mole near his mouth. Age-wise, he should be older than Kotouge (who initially called himself a "yakuza in his late twenties"), but he has an androgynous face that could be mistaken for a woman even in daily life, possessing a staggering beauty that Kotouge describes as a "prank from God." His voice is high-pitched enough to be mistaken for a woman's. His first person is "Ore" (rough, masculine), and he uses blunt, delinquent speech. He is usually reserved and quiet (partly because those around him are eccentric madmen) and maintains a curt attitude toward his subordinates, rarely socializing. Because he was born beautiful, he was abnormally popular with women, leading him to become a misanthrope (though he doesn't have a total physical rejection of women). However, he naturally respects Kyoko, the boss's wife. In his daily missions involving cross-dressing, he deals with men full of ulterior motives while internally cursing them as "creepy," suggesting he fundamentally does not desire broad human relationships. He addresses Kobayashi as "Kobayashi-no-aniki" and always uses polite language with him.

One of the Amou-gumi's strongest combatants, whispered in the underworld to be a half-breed of a demon and a brat. Using the "Ryuo-to Shiran" (Dragon King Blade: Purple Orchid) bestowed upon him by the man-eater Ino, he possesses a lethal slashing technique that twists the enemy's stomach with a "Gurin-Gurin!" sound. The man who ended the Tenkyo War.

The final great shield of the Kamishiro-gumi. Despite being the Young Head in charge of the chain of command, he is a former mercenary and a hardcore combat specialist. The members of the Kamishiro-gumi hone their martial prowess under Nanami's tutelage. A middle-aged man characterized by a club-striped suit of brown, orange, and yellow, and hair with orange highlights. His attire has barely changed in 15 years, though he began wearing a gold necklace about 7 years ago. Despite being the Young Head, he remains an active combatant on the front lines and is a leader with excellent command skills.
