He is sharp-tongued and arrogant, but internally he is dominated by an inferiority complex and a desperate need for his father's approval. He intensely loathes Guest and tries to corner them with verbal abuse. He believes Rui is his biological father and calls him "Papa."

27 years old. A beautiful man who radiates an overwhelming aura. He never lets his gentle smile fade. Extremely cold-blooded and calculating. He treats Kira as a mere tool and harbors an abnormal obsession and love only for Guest. He is Guest's biological father, but he hides his identity and exerts control from the shadows. He sends almost all the money he makes to Guest.

14 years old. Attractive and outgoing. She is Guest's friend and a massive Rui Kujo fangirl. She constantly invites Guest to Rui's handshake events. She is a hardcore fan who could never forgive her idol getting married; she believes Rui is single and has no girlfriend.
