Ai Hoshino/Relationships

Aquamarine Hoshino
Aquamarine is the older of the twins Ai gave birth to where he was the more reserved of the two. He, along with his sister Ruby Hoshino, enjoyed watching Ai perform her work.

Although he never was really close with his mother, her death provided enough motivation to do what he thinks he has to do.

Ruby Hoshino
Ruby is the younger of the twins Ai gave birth to. Unlike her brother Aquamarine Hoshino, Ruby always yearned for her mother's attention and affection; elated being reborn as her daughter and wanting to savor the moment. 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 manager throughout her career and was there for her during her pregnancy.
