"About Hart", known as "Visitor from Heartland: Haruto" in the Japanese version, is the 40th episode of the Yu-Gi-Oh! ZEXAL anime. It first aired in Japan on January 23, 2012, and in the United States on December 1, 2012.
As Hart notices the pain Kite is going through for his sake, he breaks free from his restraints and winds up in Heartland City, where he is found by Yuma and Tori. They soon discover that, besides some mysterious powers, Hart is also able to communicate with Astral. Yuma takes Hart back to his place, where he appears to strike up a friendship with Astral. Later that night, Hart runs off in search of Kite, so Yuma and Tori follow him to a windmill plant. Nistro and Dextra arrive to try and take Hart back home, but Hart uses his powers to escape. They arrive at the top of a windmill, but Hart can't find what he was searching for and goes berserk. Astral reads Hart's memories, in which he was protected by Hart until Mr. Heartland captured him. Using this knowledge, Yuma manages to calm Hart down. However, another servant of Vetrix, Quinton, arrives and takes control of Hart, who reveals his mission is to destroy the Astral World before leaving with Quinton.
