A thief wielding Number 56: Gold Rat holds a stickup at a mall where Yuma is attending. However, before Yuma and Astral can reach him, a Numbers Hunter with the ability to slow time (1/10,000 of a second) for everybody except people with numbers, Kite Tenjo, defeats him in a duel and forcibly takes his Number and his soul, leaving him old and decrepit. As Kite's younger brother Hart uses trash from Heartland City to attack Astral World, Kite converses with Mr. Heartland, revealing that the only reason Kite collects numbers was to cure Hart of an unknown illness, who then converses with the mastermind, Dr. Faker, who seeks to obtain the Number cards and destroy Astral World. The next day, as Yuma tries to save Tori from a speeding truck, time slows again and Yuma is confronted by Kite, who forces him into a duel. Kite immediately summons out two Numbers monsters in one turn, Number 10: Illumiknight and Number 20: Giga-Brilliant.
