In the year 2205, the past becomes threatened by the historical revisionists who seek to change it. Protecting history becomes the task of a boisterous band of swords that are brought to life, including the glamorous Kashu Kiyomitsu and the kindly Yamatonokami Yasusada. Beyond their battles, these legendary swords from different eras lead charming daily lives.
