Heartland what he did with him , who explains that Haruto has the power to communicate with the spirits of the Astral World , and that they need him to destroy it , or our world won ' t be saved . Kaito tells him to return Haruto back to normal , and Mr . Heartlands says that his soul had probably already left , but that there is a way to heal him , which is to become a Number Hunter and collect all the " Numbers " - and at that time , Haruto catches a butterfly with his hands and crushes it .

Faker smiles as he watches on . At Heartland Tower , Mr . Heartland tells Kaito that he ' ll be sure to convey his passionate heart to Dr . Faker . He tells Kaito he should go see Haruto , as it ' s been a while , and it will surely boost Kaito ' s will as well . After Kaito leaves , Heartland turns around and addresses Dr . Faker through a circular monitor . He tells Faker that everything is progressing well . Faker responds that that ' s fine and that the life of Kaito ' s younger brother is on the line for him .

Later , when Kaito Duel ed Yuma Tsukumo , at the instant when he would win , Orbital 7 told Kaito that Haruto was badly injured , making Kaito cancel the Duel and flee . At night after confronting Kyoji Yagumo along with others , Kaito picked up Haruto and left Heartland Tower , blowing it up in the process . He told Haruto that Kaito was taking him somewhere safe so he wouldn ' t be caught up in the chaos of the war , but Heartland Tower was also not a safe place for them anymore . However , Kyoji set up spider webs to ambush Kaito , making him Duel one of his subordinates as Kyoji held Haruto hostage . During the Duel , Kyoji tried to anger Kaito , leaving Haruto suspended over a building with a spider thread ; however , watching his big brother get hurt in the Duel made Haruto lose control , creating a huge sphere of energy .

Kaito asked Kyoji what he had done to Haruto , with Kyoji saying that he would give him a hint : Haruto could only see Kaito as an enemy right then , and commented that was a pity . He explained that the " empty shell " Haruto wasn ' t even able to recognize his only blood relative , but that if Kaito became his subordinate , he would be able to meet the true Haruto again . Kaito declined , asking who would be crazy to help Kyoji , with Kyoji telling him to fight then , as much as he wanted to .
