At Otori Mountain, Hanzo is captive with Kagetomo and his Ninja Corp. Hanzo tells Kagetomo to remove his mask as it was obvious from the ropes tying him that it was he who had captured him. At Ninja Village, Saizo tells everyone that it was Kagetomo and his henchmen who had kidnapped the chief. He explains to Ash and his friends that Kagetomo was a powerful ninja from Ninja Village who was to be the next village chief. However, he had run away with Heidayu because he was denied the position of chief due to his thirst for power. Kagetomo had then formed a ninja force to capture Hanzo. Saizo had planned to stop him, but had come too late to save Hanzo.
Back at Otori Mountain, Hanzo asks Kagetomo whether it was the chief's emblem that he desired. However, Kagetomo says that he would not steal it, but instead, Hanzo would give it to him at tomorrow's festival and announce him as the new chief.

Meanwhile, Ippei is facing difficulty battling Kagetomo's Weavile. Hanzo silently appreciates Weavile's power but says that it lacks one thing which Ippei has.

However, in that time, Greninja emerges from the ground to attack Weavile. It then finishes off with Water Shuriken, defeating Weavile. While Kagetomo becomes angry at Weavile, Hanzo tells Kagetomo that his Weavile is far stronger than Ippei's Greninja.
