Romance between swordsmen, based on a true-life adventure of a young girl determined to be a part of history. In the 1860s in Japan, a new era is dawning. During this time fraught with violent social upheaval, samurai of all walks of life flock to Kyoto in the hope of joining a band of warriors united around their undying loyalty to the shogunate system. This group becames one of the greatest (and most infamous) movements in Japanese history...the Shinsengumi! When Sei gets wounded, Soji takes her to Doctor Matsumoto, an old family friend who knows her secret. While in his care, Sei tells him of the resentment she feels toward her father, who neglected his family to pursue his medical practice. Matsumoto reveals the truth about her father and the sacrifice that affected his family's destiny.
