Kagetora, a young ninja, is granted the prestigious opportunity to serve a renowned family of martial artists. However, his assignment presents a daunting challenge: to instruct Yuki, the heir of the dynasty, who is charming but clumsy, in the art of self-defense and combat.
Yet, the complication in this task does not arise from Yuki's inability to grasp martial arts. Rather, it emanates from Yuki herself. As the future owner of her family's dojo, Kagetora's role as a ninja forbids him from falling in love with his master - an act deemed as the ultimate betrayal of his duty and a grave dishonor. Can Kagetora help Yuki refine her movements, or will he succumb to his emotions for her?
