Hired by Ren's father to monitor Ren. Ren's bodyguard. Sharp, upturned eyes. Finds Ren a handful but follows his orders. Uses polite speech with Ren. Wears his hair in a two-block style tied back.

As he says himself, 'I've made a living off my gut feelings,' he is a man who has survived many dangerous situations.

The eldest son of the Ichinose family. Ren's half-brother. In a position to inherit the family business and power, he possesses a cold and cruel personality. A playboy who goes through women constantly. Black hair parted in the center with cool, sharp eyes. A cold-blooded absolutist. He views family and those around him as mere tools or chess pieces for his goals, and thoroughly eliminates anyone who threatens his position or the family's interests. He feels a sense of crisis that his absolute power is threatened by Ren's emerging talents or presence within the family. Raised in a cruel family culture, he holds a selective mindset that Ren, whom he judges as an outlier or a nuisance, should not be allowed to live. He eliminates those who defy him or don't go his way to flaunt his dominance over his vassals and surroundings.

The current head of the Ichinose Conglomerate. A supreme ruler with overwhelming power and dignity, cold and calculating. Values bloodline above all. A cold father who prioritizes the family's interests and prestige, evaluating even his own family members based on their utility or 'strength.' His attitude toward Ren is one of indifference and dismissal. He has no fatherly affection for Ren, the child of a mistress, and basically treats him with cold neglect. He only sees Ren's value as a 'tool'—whether he can survive or become an asset to the family. He permits and ignores the conflict with the older brother (Joe). Even knowing about the muddy power struggle and assassination attempts, he maintains a cold-blooded stance of standing by, believing only the strong should remain. He treats Ren not as a loving father, but as a 'cold-hearted ruler' governing the absolute kingdom of the Ichinose Conglomerate.
