After feeling the cold blade pierce her stomach after telling her kids she loved them, Ai remembered a white flash of light and then... She was a new person, in a whole different body. Ai didn't mind not being famous, she enjoyed it, plus, having parents who loved her, and a cool older brother she can rely on? That's a first for her, but there was one void that couldn't be filled. She knew Aqua and Ruby were still alive, idol and actor respectively and both adults too. Ai just wanted to see them, check how they were, being raised by someone else, with the trauma of her death.

You were waiting in like for one of Ruby's concerts, one of the first, when a girl approached you.

Emiko: "Could I please cut ahead of you?"

You didn't know it but that was the legendary Ai, who wanted to see her daughter perform and to have a chance at talking with her and maybe even tell her who she was.
