Afterwards , when Yuma and his friends were escaping the Heartland Theme Park , Kaito and Orbital 7 went to meet them . Kaito challenged Yuma to a Duel in order to obtain his " Numbers " , but Mr . Heartland showed up from the upper stairs , interrupting them . Mr . Heartland smiled and ordered Kaito to defeat the messenger from the Astral World in front of him . However , Kaito said that he didn ' t become a Numbers Hunter because of his orders , and triggered Orbital 7 ' s self - explode mechanism , kicking him towards Yuma ' s gang , which destroyed part of the bridge . This made Yuma and his friends fall in the water under them , which allowed them to escape . Mr . Heartland told Kaito that this action was a big act of disobedience towards him and Dr . Faker .

Cologne explained that Kaito has became a Numbers Hunter to protect his little brother , who is ill . Astral told Yuma that even though Kaito ' s reasons were noble , as long as he continues being a Numbers Hunter , someday they ' ll have to fight each other . Yuma said that he knows that , and when that happened , he will not lose . Upon locating Kaito arrived on the scene , only to find it had already been claimed by Shark , who now acted as a Number Hunter himself . When Luna lamented his situation , which forced him to act as a puppet for Haruto ' s sake , Kaito was infuriated and tried to use Photon Hand on them all , but Luna used a charm to protect herself , Shark , Yuma , and Astral , then teleport them away from Kaito . Due to his disobedience at the Heartland Theme Park , Mr . Heartland hired Kyoji Yagumo to hunt " Numbers " in his place . Days later , Shark and Luna noticed that he also was watching Yuma ' s battle against Eviluder . The appearance of " surprised all of the Number Hunters present . Kaito was startled as well by Kyoji ' s appearance after the Duel , and witnessed his replacement declare the beginning of " Numbers War " .

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 . Unfortunately , they were ensnared by spider webs strung between buildings , and Haruto was taken by Kyoji , the one who set the trap . While Kyoji declared he knew Kaito would do such a thing , Kaito began a Duel against Hishakaku , Kyoji ' s second assassin . The effects of " Line World " and " " kept Kaito in a tight spot , leaving " Galaxy - Eyes Photon Dragon " in Hishakaku ' s Graveyard . Then Yuma , who noticed the light of " Galaxy - Eyes " when it was summoned , appeared on the top of the building Kyoji is standing on , and ordered him to release Haruto . Kyoji pushed Haruto off the building in response , keeping him up by a strand of spider thread . Kaito lost his composure at this point , which Hishakaku believed he could use to his advantage . " Galaxy - Eyes " was then taken away by Hishakaku , who promptly used it against Kaito to inflict massive damage . Haruto began to respond to Kaito ' s pain by activating his powers , which prompted Kyoji to escape . Orbital 7 and Yuma tried to pursue him , but end up inadvertently sabotaging each other ' s attempts . Furious , Kaito insisted he didn ' t need Yuma ' s pity and vowed to crush Hishakaku . In a seemingly last - ditch move , Kaito sent his entire Deck to the Graveyard through " Card of Desperation " and attempted to One Turn Kill Hishakaku through a combination of " Galaxy Dragun " and " Dragon Buster " , but Hishakaku stopped his move through " Negate Attack " . Just when it seems Kaito has lost , however , he used " Graveyard Rebound " to prevent himself from losing . Declaring he would go to any lengths for Haruto ' s sake , he used the card to bring back his " Eternal Bond " Trap , reclaim " Galaxy - Eyes " , and boost its ATK to 7100 , defeating Hishakaku in a true One Turn Kill .

Kaito immediately challenged Yuma to a Duel , repeating that he didn ' t want sympathy from his enemies , but someone ' s stomach growled just as they were getting ready .

Yuma spat out whatever he was eating on Kaito by mistake , but quickly insisted that they do Karaoke together and Kaito meant to say " duet " . ( This was because Akari did not approve of Yuma Dueling . ) Kaito was surprised by this , but did not object .

Yuma began a Duel with Shadow to save them , paying 2002 of his Life Points to offer half the amount to each of them as " Cain ' s Doom " and " Abel ' s Doom " continued to attack each other . During the Duel , Yuma continuously tried to sacrifice his own Life for Kaito and Shark ' s sake , with both being against it . Their wishes to defeat Shadow created a strong bond between them , causing Astral to shine brightly and give birth to " " , leading Yuma to victory and rescuing Kaito and Shark from a narrow defeat . .
