Romance between "swordsmen," based on a true-life adventure of a young girl determined to be a part of history. In the year 1863, a time fraught with violent social upheaval, samurai warriors of all walks of life flock to Kyoto with the hope of joining the Mibu-Roshi--a band of warriors united around their undying loyalty to the Shogunate system. In time, this group would eventually become one of the greatest (and most infamous) movements in Japanese history...the Shinsengumi! Sei devotes herself to becoming an ideal bushi, or warrior, and accompanies the Mibu-Roshi to Osaka. There, she finds the man responsible for killing her father and brother. Desperate to avenge her family, Sei uncovers his hideout with the help of a friend, but they are soon discovered and her companion is slain. Is Sei ready for the hardships of the Mibu-Roshi? Or should she return home to lead the life of a normal girl?
