In the last round of the B-Master Battle, Kamon faces Riki in the battle to determine the future B-Master of the East. As the battle begins in a Meteo Bomber showdown, Riki quickly scores a point ahead of Kamon. And all while this is occurring, Ryoma makes a surprise appearance, as he takes off his mask...
Due to the restoration of Kamon's memories by Ryoma, he and Garuburn become encased in a dark aura that brings out their inner darkness against their will.

In order to surpass the darkness, bring back his friend and become the Eastern B-Master, Riki obtains a new power.
