Haruta Maho (Yoshida Mizuki), a hit manga artist who gave a shocking speech at a manga award ceremony, sneaks into her alma mater and ends up traveling back in time to her high school days 10 years ago...! The day she traveled back in time was the day that Yukishima Shu (Fujiwara Itsuki), a senior in the manga club, first praised Maho's manga. Knowing that Yukishima has only a short time left to live, Maho uses the drawing skills she has cultivated over the past 10 years to assist Yukishima in drawing "Revive Line" as quickly as possible and having him see it published as a one-shot. Although the work is complete, Arashi Kagemasa (Okura Sorato) from the student council comes to the manga club room, and a new problem arises.
