When seventeen-year-old Rileigh Martin discovers she may be harboring the spirit of Senshi, a samurai, she is torn between continuing as an ordinary, shoe-loving girl and embracing the warrior inside, with help from a handsome martial arts instructor, Kim.

With graduation nearing and Kim regaining his memory, Rileigh is ready to celebrate but Sumi not only regains her memory, too, she performs a ritual to switch bodies with Rileigh, draining her ki and placing her in grave danger.
