The events of the story are meant to take place during the time of peace between the first and second games of the series. The story begins with Nakoruru on a bloody battlefield in the midst of a snow blizzard. She has suffered a deep wound on her back and collapses, hallucinating slightly due to the cold and blood loss. The audience is treated to a brief flashback of Rera and Nakoruru at the battlefield. It's insinuated that she received her wound from a child armed with a sword. Rera raises her arm to finish him and, through a reflection in the child's eye, we see Nakoruru mirroring the same action. She is found by her childhood friends, Yantamu and Manari, and is brought back to Kamui Kotan.
