One day the combination of a wild storm and a mysterious booster pack suddenly means they can bring Hiro, one of the game's characters into their world. Excited but worried their secret will be discovered, the boys decide to take Hiro to school where he is mistaken for a Japanese exchange student. Despite this temporary solution the portal being open means that more people and monsters from Hiro's world can travel to Earth, wreaking havoc on the small town. The boys decide in order to get things back to normal they must send Hiro back but not before their school dance is overrun with Battle Day Zero characters.

Exchange Student Zero

An ordinary summer holiday gets complicated when two kids - Jan and her brother Dean - are packed off to stay with their drop-out uncle, Woody. It should be complete paradise: a secluded island, great waves and a relaxed adult in charge. What could be better? But why is this place so deserted? Why has the town been overrun by jungle and what are those strange noises coming from the beach? The terrible truth is revealed when it turns out the locals are in fact surf-crazed monsters - and they don't take kindly to tourists. Well not at first anyway. The arrival of a rampaging property developer changes everything. Sibling rivalry and genetic differences are suddenly swept aside, as everyone bands together to save the strange little place they've all come to call home.
