Summary[]
During the filming of That Was the Start, Ai came to see Gotanda. Seeing as Aqua had fallen asleep on the director's lap, she commented that Gotanda had almost become a father for Aqua. She the complemented his scripts and requested him to film a documentary about B-Komachi. He was reluctant at first but ended up agreeing to it. Most of the footage were shot, with the final segment being the dome performance, but since Ai was murdered, the documentary was never completed.
In the present, Gotanda regretted not reaching out to Ai as he pushed to film the real her. Meanwhile Aqua approaches Kaburagi with the script of The 15 Year Lie, a movie about Ai and her murder. Kaburagi explains that due to sensitive subject matter, it will be tough to find a distributor. He also feels manipulated into taking on such a project but ultimately agrees to produce it, feeling only he can do justice for such a project.
The provisional cast list consists of:
- Ai, played by Akane Kurokawa;
- B-Komachi members, played by Ruby Hoshino, Mem-Cho and Kana Arima;
- President of Strawberry Productions, played by Melt Narushima;
- The manager Miyako Saitou, played by Frill Shiranui;
- Lalalai's headliner, played by Taiki Himekawa;
- Culprit/Murderer, played by Aqua Hoshino.
Later, Aqua visits Ai's grave and vows "I'll fulfill your actual wish."
