Sakura is the second daughter of the Odoru family who has lived a quiet life between her talented older sister and her beautiful younger sister. She has no special skills except for taming small magical beasts. However, her life changes overnight when she is taken away to become the bride of Prince Kai, a man feared as the War God.
The reason for her sudden marriage is that Sakura possesses a body that can act as a scabbard for the legendary Demon-Slaying Sword. Although Kai keeps her by his side only for this purpose, her wisdom and kindness begin to change the cold prince little by little. This is a beautiful Cinderella romance about two people who struggle to express their feelings but eventually find a deep and lasting love.
