Kamza, a vibrant kingdom located on a lush ocean island, is in the midst of a national event celebrating the upcoming marriage of their princess to a valiant knight. But when a group of assassins appears during the ceremony, this dream come true transforms into their worst nightmare. As the knight lays mortally wounded, the princess reveals her longhidden secret - there is a second soul living within her, and together they control the power to travel through time. But can they act quickly enough to reverse the course of history and find out what happened that fateful day? Only time will tell...

The story centers on Toki, a princess, and Towa, the alter ego who shares her body. The two personalities each have their own skills and temperament, yet both are bound to the same man, Zack, whom they love. Rather than a grand quest to save the world, the tale turns on something more intimate: love, commitment, and the road to marriage. As their adventure carries them across time, the bond between Toki, Towa, and Zack is tested, and the complicated romance at the heart of their journey slowly comes to a head.
