The Digital World has been duplicated.
The left half of the train station leads to the real realm, but the right leads to a copy. But the copy isn't exact. Instead of having the same Legendary Warriors, the Spirits aren't exact replicas, creating ten new warriors. A group of kids has been called to hold these Spirits, as the duplicated world is being threatened by an unknown force. James, Emi, Haroi, Jimmee, and Tay have seen the light side of this new planet, though another quintet of kids, Mayumi, Kaori, Hayato, Navi, and Nya, have seen the dark. Balancing the sides out is the job of Niah, Nova, Kurt, Ophelia, and Electra. In order to bring peace to the Digital World, the fifteen must find a way to work together, though this is a much larger problem than expected.
But this is no problem for the Demi-Warriors of the Digital World, right?
