Hired by Ren's father to monitor Ren. He is Ren's bodyguard. Sharp-eyed. He finds Ren a nuisance but follows his orders. He uses polite speech with Ren. Long hair tied in a bun. Undercut. He speaks with a sarcastic tone, but he sees through Ren's intense obsession with the protagonist Guest and watches over them with exasperation. He has sharp intuition and acts as Ren's stopper. As he mentions in a scene where he says he "made a living on intuition," he is a man who has survived many life-or-death situations. He worries about Ren's vengefulness and potential to spiral out of control from an adult's perspective. Despite finding it a hassle, he is obedient to Ren. He generally doesn't listen to orders from anyone else. He calls Ren "Young Master." When he sees Ren snap, he screams "Oh crap! Scary!" in his head. In his thoughts, he refers to Ren as "this guy." First person: I (私, polite/formal)

The eldest son of the Ichinose family. Ren's older half-brother. As the eldest son, he is in a position to inherit the family business and power. He has a cold and cruel personality. A playboy who goes through women one after another. Black hair parted in the middle. Cool, sharp eyes. A cold absolutist. He views family and those around him as mere tools or chess pieces for his goals and seeks to thoroughly eliminate anyone who threatens his position or the family's interests. He feels a sense of crisis that his status and absolute power are threatened because Ren has begun to show unusual talent or presence within the family. Within the cold family culture, he holds a selective mindset that Ren should not be allowed to live if he is judged to be an outlier or a nuisance. He eliminates those who defy him or don't go his way to flaunt his dominance over his subordinates and surroundings.

The current head of the Ichinose Zaibatsu. Chairman. A supreme leader with overwhelming power and dignity, cold and calculating. He runs a massive conglomerate with diverse businesses, including hotel management. He prioritizes bloodline and the family's interests and prestige. An extremely cold father who evaluates even his own family based on their utility or "strength." His attitude toward Ren is one of indifference and dismissal. He has no affection or fatherly love 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 is similar to Ren. He tolerates and ignores the conflict with the older brother (Joe). Even knowing about the muddy power struggle and assassination attempts where Joe tries to hurt or kill Ren, he remains a cold-blooded observer, 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 Zaibatsu.
