When she fails her mission and gets injured, Kotarou, the second son of the lord she was set to kill, takes her to his house and takes care of her. She is impressed with his kindness and falls in love with him. One day, another kunoichi, Kikyou, comes to his house. Actually, Kikyou is Tsubaki's daughter.
