Tony, a boy from Earth, was running in a race and stopped to do his laces, is pulled over into the other world while his soon to be female companion tries to steal the book, thinking that she is the chosen one. But her master caught her and made her listen to reason.
Tony and the girl soon end up fighting people among their enemies. Tony has a rock which was given to him by his grandfather, he threw it as instructed by the girl and a blue beast that looks like a dog came. He helped them fight. The girl had her own one. Their other companion, male, also joined when the master told Tony about everything and what they had to do. They had to find the gems that fit into the legendary book.
I remember that once in the series they were up against a challenge in which there were multiple copies of the legendary book and they had to select only the authentic one. The girl remembered that she had spilt tea on some of the pages and thats how she recognized the book. Once those 3 even travelled to Earth and with Tony’s grandfathers ate pizza in a restaurant. They got to learn more about his grandfather and his connection to the other world.
I watched this very long ago on TV, maybe on POP TV or KIX TV, I don't remember but I really want to find this series.
