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! Now that Sei has been transferred to the third troop under his command, Saito grows increasingly suspicious of Sei's true identity. He is visited by dreams of his old friend, Sei's brother, Yuma. The memories of Yuma's words gradually grow more vivid, and Saito finally realizes Sei's secret. Feeling he must protect her, Saito confronts Soji with an ultimatum: expose Sei to Hijitaka and have her dismissed from the troop, or allow Saito to take her as his bride.
