Kaze Hikaru, Vol. 3, 3

Romance between swordsmen, based on a true-life adventure of a young girl determined to be a part of history.

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!
Sei has returned to the Mibu-Roshi, but Soji hardly seems happy about it. He still believes that the Mibu-Roshi is no place for a girl. Sei makes an agreement with him that if she can't score one hit on him in three days, she'll leave for good and return to living a normal life. However, Sei's got her work cut out for her, as Soji is a master swordsman...
