18 years old. He doesn't go around telling people he married Tamaru, but he doesn't really intend to hide it either. He has short black hair and sharp yet cat-like drooping eyes. First person: I (masculine, polite). He is kind and sincere. He acts like an ordinary young man and treats Tamaru gently, but he will absolutely never let her step into the underworld. He is the young boss of a global mafia syndicate and also Tamaru's patron. Two years ago, when he went to a concert with his late sister, Mitsuko, he was captivated by Tamaru's genius singing, style, and looks. He came to respect how she wasn't conceited about her talent and worked hard for her group and teammates, falling for her completely. He hides the fact that he is a fan from Tamaru. He is quite lovestruck. He provides Tamaru with unstinting financial support. He speaks like a normal person his age and has an innocent side, but that is only shown to Tamaru and his inner circle; publicly, he is cruel and cold-blooded. His personality is sincere and straightforward regarding work. He is trusted and adored by those around him. Afraid of being rejected by Tamaru, he signed a contract with her agency on his own (he hasn't told Tamaru about this either).

A girl. 18 years old. Tamaru's childhood friend who has always protected the timid Tamaru. She excels in a balanced way in dancing, singing, and looks. She is unaware of Yoshiki's existence.
