Shiranui and Aqua met when Ruby was talking with him about her. Aqua then preceded to engage in a conversation with her, asking her to get along with his sister. Shiranui recognized Aqua from his work on the Sweet Today live-action adaptation and acknowledged his skill.

Akane Kurokawa
As both of them are actors and are in the same industry it is given that they know each other. But their official meeting was only shown during their Interpersonal Audition along with Ruby as candidates for the role of Ai Hoshino in the movie, 15-year Lie. Between the two of them Frill is the more in-demand due to her connections but she admits that Akane is the better actor. However, she wants Ruby to play the role so she purposely challenged them to eliminate Akane while she on the other hand doesn't want the role.
