Yu☆Gi☆Oh! Zexal (Dub)

In the bustling and futuristic city of Heartland, a young boy named Yuuma Tsukumo has a dream that everyone his age wants to achieve—earning the title of the greatest duelist! Sadly, due to his lackluster dueling skills, this dream is far from achievable. But when the school bully, Ryouga "Shark" Kamishiro, splits the key given to him by his father into two pieces, he inadvertently sets Yuuma on a collision course with his dream. Retaining one half of the key, Yuuma begins a duel with Shark, but soon realizes that his inexperienced skills are no match for him. In a sudden turn of events, Yuuma's key repairs itself, and the "Door of Destiny'' appears before him. Using the key to open it, Yuuma is greeted by an alien by the name of Astral—a being only he can see. The bewildered Yuuma soon learns that his memories have been divided into 100 "Number Cards," all of which he must retrieve. However, he is also not the only one looking for them. Bombarded by these revelations, Yuuma, alongside Astral, must defend the world from the upcoming threats that loom over Heartland City—regardless of any divine intervention that may occur. Yu☆Gi☆Oh! Zexal follows the adventures of Yuuma Tsukumo in his hometown, the futuristic city of Heartland. Yuuma is an amateur duelist who wants to become the world's greatest Duel Monsters champion, having learned the basics of dueling from his father who disappeared long ago under mysterious circumstances. Always pushing himself to the limit in order to prove himself, Yuuma soon finds himself outmatched when dueling a bully to recover his friend's stolen cards. Just as hope seems lost, a mysterious spirit named Astral appears and helps Yuuma to win the duel.
