Three hundred years ago, in the icy expanse of Siberia, Jubei Yagyu fought a fierce duel against Kitaretsusai of the Northern Yagyu clan. The battle left Jubei’s daughter, Freesia, trapped in suspended animation. In the present day, global warming awakens Freesia from her frozen prison, and she arrives in Japan as a middle‑school transfer student. There she befriends Jiyuu Nanohana, unaware that Freesia has set her sights on the coveted Lovely Eye Patch, which she believes rightfully belongs to her.
