With the help of producer Masaya Kaburagi, Aquamarine "Aqua" Hoshino and Kana Arima have landed the roles of Touki and Tsurugi in Lala Lai Theatrical Company's stage adaptation of the popular manga series Tokyo Blade. Co-starring with them is Aqua's girlfriend, Akane Kurokawa, who plays Touki's fiancée, Princess Saya. Due to the fanbase preferring Tsurugi as Touki's love interest, Saya has made fewer and fewer appearances in the manga, making it difficult for Akane to fully immerse herself in the role. Her struggles are compounded by differences between the play's script and the original work—differences that also frustrate Tokyo Blade's author, Abiko Samejima. Aqua, however, is more concerned with his personal goals than he is with the play. He has only one objective in mind: to grow closer to director Toshirou Kindaichi and find out what he knows about Aqua's mother, Ai.

Fourth-grader Ayumu Fujino regularly draws four-panel manga for her school newspaper and is lauded as having the best artwork in her class. One day, she is asked by her teacher to turn over one of her manga slots in the school newspaper to a truant student named Kyomoto. When Kyomoto's manga pops up alongside Fujino's, it receives high praises for its detailed artwork, making Fujino furiously jealous. Refusing to be beaten by someone who barely attends school, Fujino devotes herself to learning to create manga. As time goes on though, her goal of outshining Kyomoto seems to only get further and further away, and Fujino, now in sixth grade, eventually gives up and quits making manga. Graduation day arrives, and Fujino is asked to deliver Kyomoto's graduation certificate to her. Through chance, the two end up coming face to face, and their unexpected meeting will end up having consequences far beyond what either of them could ever predict.
