In the 10 years since Ai's death, Ichigo has fallen out of contact, Ai's idol group B Komachi was disbanded, and Miyako closed down Strawberry Production's idol unit to focus on internet personalities instead. Ruby meanwhile has been auditioning to become an idol, unaware that Aqua has been using his acting skills to secretly sabotage her applications and give her false rejection notices. However, he cannot stop Ruby from being scouted by an underground idol group. Not trusting the management of the underground idol group and wanting to support Ruby's wish to become an idol, Miyako decides to finally reopen Strawberry Production's idol unit with Ruby as its first member. Meanwhile, Aqua works as director Gotanda's apprentice, but has given up on trying to be an actor and is content working behind the scenes to find his father. Gotanda advises Aqua not to give up on his dreams so easily, causing him to recall Ai's last words to him. Aqua and Ruby are later admitted into the prestigious Youtou High School which has a performing arts department. While visiting the school, the twins encounter Kana again, who is glad to see Aqua again but is shocked that he is enrolled in the general education department instead of performing arts.
