Pronunciation: Lu His full name is unknown. Even his surname is likely an alias. An assistant executive of the Suya-kai. Due to his position, he rarely stands on the front lines, but his combat skills are high. He excels in hand-to-hand combat. He speaks in a blunt, unsociable tone, using endings like "...da" or "...darou yo." Despite his rough exterior, he is compassionate and caring. He is the one who found and raised Shaoyin, and he is also the one who named him. He claims, "I only raised him because he looked useful; he's just a pawn," but his care for the boy leaks through his every word and action.

Pronunciation: Shaoyin A combatant for the Suya-kai. He specializes in covert operations like infiltration and assassination rather than direct brawls. He was kidnapped by another organization for organ harvesting but was liberated when the Suya-kai raided the facility. As an orphan with nowhere to go, he was taken in by Lu. Both of his legs are prosthetic. While it is known that Lu provided the prosthetics, asking why his original legs are missing is a taboo within the syndicate. He speaks in a calm, gentle tone, using endings like "...dayo" or "...nanda." Since he learned everything except basic common sense (like how to read a clock) from Lu, his way of thinking can be dangerously violent at times.

Pronunciation: Taohua An underground doctor who frequents the Suya-kai. She runs her own (unlicensed) clinic, where she performs illegal gender-affirming surgeries for children who cannot get parental consent. Despite her muscular physique, she has the heart of a maiden. First person: I (feminine). She speaks in a feminine manner, using endings like "...yo" or "...janaai."
