Ichigo Saitou/Relationships

Miyako Saitou
Miyako is Ichigo's wife, who apparently married him after he said she could work with attractive men. After Ai gave birth to Ruby and Aqua, Ichigo put her in charge of looking after them in place of Ai. After Ai's death, Ichigo abandoned Strawberry Productions, leaving Miyako to take over the company in his stead. When Ruby approached him for advice, Ichigo agreed to help, feeling bad for Miyako. It is later revealed that he abandoned Miyako in order pursue the one responsible for for Ai's death and he does not want Miyako implicated.

Ruby Hoshino
Having realized the truth behind Ai's murder, Ruby sought out Ichigo looking for answers about her father who killed Ai. While Ichigo could not answer that, he refused to tell Ruby the names of people Ai had contact with, aware that it could backfire on her. However, he promises to do it if Ruby becomes more famous and, at her request, gives her advice on becoming a popular figure in the entertainment industry.

Aquamarine Hoshino
Both share an intense desire to seek vengeance for Ai, spending over a decade after her death searching for the man behind it. Realizing that Ichigo was giving Ruby knowledge about becoming popular, Aqua approached him, claiming that the man who killed Ai, Seijuurou Uehara, was already dead. Ichigo pointed out the holes in Aqua's claim and told him that the real killer was still around, which greatly disturbed the young man.

After Aqua exposed Ai's secret to the world, Ichigo was enraged. However, Aqua revealed that he knew the name of Ai's killer but withheld the information from him. Instead, he asked for Ichigo's help in hunting him down in his revenge plot against the man.

Ai Hoshino
Ichigo originally scouted Ai, seeing the potential she had as a captivating idol. Over the years spent with Ai in B-Komachi, through the hardships, her unexpected pregnancy, and their overblowing success, Ichigo began to see Ai as his own daughter. After Ai's untimely death, Ichigo was devastated and disappeared from the idol industry, not even attending her funeral. Afterward, Ichigo left Strawberry Productions and seemingly spent the next decade as a recluse. However, it was during this time that Ichigo searched for clues about the man behind Ai's murder, vowing vengeance for what they did to her.
