Assimilation: Part 1

Synopsis

While Yuma fights his battle in the Astral World, riots break out across the Earth. About a million Numbers scatter across the world, and a foul aura billows from everyone who picks one up. Suspecting this is the Barians' doing, III and the others are confronted by Mr. Heartland — the very man who once tormented Kite and Haruto. To defend this world in Yuma and Astral's stead, Kite accepts the duel of unfinished business. But in Mr. Heartland's hand is a new Number.
