Ai Hoshino/Relationships

Aqua Hoshino
Aquamarine is the older of the twins Ai gave birth to, and he is the more reserved of the two. He and his sister Ruby enjoyed watching Ai perform her work. Formerly her doctor, Goro Amamiya in his previous life, he adored her even more after that he reincarnated as her son. Despite the years they spent together as mother and son, Aqua admits that he has not totally known Ai as a person.

Although he was never close nor called her mother even once, he cared so much for Ai. Her death was so much to take that it easily changed him and drove him to the path of vengeance. He was never himself since then. Because of his regret on failing to save her (though he was just a child) he could not think of being happy in life and just spent the next years planning his revenge to make her ex and their biological father pay for her death.

Ruby Hoshino
Ruby is the younger of the twins Ai gave birth to. Unlike her brother Aqua, Ruby always yearned for her mother's attention and affection, elated being reborn as her daughter and wanting to savor the moment. She was Sarina Tendouji, a frail and terminally-illed fan of hers in her previous life. It was because of Ai that she conquered her weakness to move, which always leads to her falling over that seem to last even in her new life that prevents her from dancing. Dancing would later become her forte as an idol and member of the new B-Komachi, combined with her looks that she inherited from her mother. Her mother's work inspired her to become an idol in her footsteps, her death exemplifying what passion was already there.

Ichigo Saitou
Ichigo was Ai's scout and manager throughout her career and was there for her during her pregnancy. He takes great pride in her as his talent and the ace of B-Komachi. Together, Strawberry productions tasted great success and all that's left is the performance to the dome, a feat that almost every performer dreamed of. However, her sudden death hit him pretty hard because she was like a daughter to him. He could not attend her funeral and went missing since then. The reason was that he's looking to uncover the truth behind her death and swore to make the culprit pay. Currently he's helping Ruby to be more popular and also promised his help to Aqua in hunting down the killer.

Taishi Gotanda
They first worked together when Ai was given a role as the main female character's classmate on a show he was directing. However, the twins particularly Aqua did not like how her parts were cut a lot and angrily questioned him on the phone. As in little to no screen time. Gotanda admits that its such a waste to do that, especially on a charismatic one like Ai. However, that was exactly the reason why the agency of the female lead asked him to cut a lot of her parts. As she stands out too much their talent would be overpowered. To make up for this, he offered Ai to star in the film he's also doing which is the That Was the Start but under the condition that Aqua is also included in the cast. The film was a great success, earning him awards and nominations.

When Ai noticed how Aqua is strongly attached to the director, she began to trust him very much, even to the point of asking him to direct a documentary film about B-Komachi. He eventually surrendered to her persistence but he asked her to show her real self or he will stop it anytime. It was almost done and their actual performance to the dome was just waiting to be filmed to complete the documentary until Ai's death suddenly struck. Prior to that she gave him two CDs, one for each of the twins when they turn 15. Because of that he could not help but wonder if she knew of her impending death.
