The world is both shocked and confused when a bunch of mysterious cards are distributed amongst the children, in which the cards can be used to summon creatures from another dimension. These cards soon become all the rage, and children begin to form groups so that they can battle one another in teams. However, when one group summons the power of a being called Drago, they find themselves sucked into the dimension of the monsters, and must now work together in order to get back home and restore balance.
