There was this old TV show probably released at the end of 2000's or early of 2010's it was about a group of people (probably Asian, don't remember it properly) they had some kind of stones or something. Both the bad group and the good group had these stones. No one knew each other initially.
What used to happen was that whenever a good guy and the a bad guy were close to each other they would be sent to another dimension and they would fight using something, I don't remember what exactly probably something like Beyblade.
