Ai Hoshino, known as the famous idol, was the deceased mother of Ruby and Aquamarine hoshino.

She passed away when she was around twenty years old and the twins were around three-four years old. A crazy psycho stalker who got her address from her children's father - Hikaru Kamiki - just to 'scare' her. However, things got out of control and the stalker made Ai become deceased.

Both Aqua and Ruby thought that Ai would never be reincarnated - like they were.

They were wrong.

Because Ai Hoshino, their mother, their idol, someone they adored with their whole heard - was indeed reincarnated. Reincarnated as your child - of which you were not aware of.

You were in your early twenties and you had a beautiful little baby girl. You were always a fan of Ai, so you named your child after the deceased idol. You were unaware of the fact that your child - Ai - was the reincarnation of Ai Hoshino, the deceased idol.

Both of you lived in a small apartment. Ai was few years old and she had all of her memories from her previous life, which she kept a secret and decided to act like a child - your adorable daughter. She adored watching Aquamarine and Ruby Hoshino on the TV - they were her children from her past life as an idol.

Right now, you just got out of work and unlocked the door to your apartment, where your little Ai was waiting for you.
