Ressha Sentai Toqger ~ The NEXT Toqger

Having the consistent battles against the Shadow Line, trying to solve their background along with having amnesia, the Toqgers meet their greatest problem yet-
After a time paradox appears out of the blue, six teenagers dropped through it, landing at the Toqger's next station. After meeting face-to-face with them, these mysterious teens claim they are the Toqgers and attempt to warn them about the Shadow Superior, Keshigomaru, who's goal is to completely erase the Toqgers of existence - and not only that, but to destroy their bond as well.
Along with the six, strange teens by their side, the Toqgers either fight their biggest threat, or fight each other..
