Since childhood, Harusumi Minami has carried vivid memories of Veronica, princess of Zerestria, a kingdom that fell in ancient times, and believes himself to be her reincarnation. Saying so out loud pushes everyone around him away, until in middle school he finds that the magic Veronica once studied answers to him as well. He is not the only one reborn: others who died with her at Reinsberg Castle are back too, sitting in his classroom and slowly recalling who they were.
