The Shattered Heart - S1.E10

As Oubu finally achieves its complete form, Entei stands before it controlled not by Reoko, but by Zetsubi. Laughing boldly, she tells the shocked Azuma that he can't beat Entei, but Kinoa insists that they and Oubu are different from before. Zetsubi is cornered by Oubu's ferocious attack, so she takes the Russian team's Bubuki to use as Entei's limbs, and Oubu is overwhelmed again. Can Azuma and his party win this fight?
