Cardfight!! Vanguard G

Synopsis

Chrono takes on a quest from a foreigner who wants him to show how Vanguard is played in Japan. At the rendezvous point, Chrono meets the client, a young Spanish man named Jaime Alcaraz. Despite what the quest said, the overly-positive Jaime is more interested in sightseeing and learning about Japanese culture than playing Vanguard. After much shopping, sidetracks, and run-ins with Shion and Tokoha, Chrono and Jaime overhear two children arguing; one little boy wants to have a cardfight with the other older boy, who refuses him. Jaime persuades that boy into fighting by offering him the delicacies he bought throughout the day. So, the two boys fight, and the younger boy manages to win. Afterwards, the two kids become friends, and Jaime decides to give all of his food with both of them. Just when Jaime finally wants to play Vanguard with Chrono, Mamoru appears and reveals Jaime's real identity; he is a rising star fighter from the European League and has been invited to Japan to compete as part of the Euro team in an interleague match against the Tokyo team (which Mamoru is a member of). In the end, Jaime recommends for Chrono to watch the match and then takes his leave with Mamoru.
