The Powerful Helper

The group sets out to disarm the traps without Gennou finding out. The research then concludes that Gennou set the traps 30 years ago, as part of a mission for the Hidden Heat Devil Village, which was destroyed by another village shortly after he completed his mission, resulting in his son's death. Naruto comes to terms with the fact that the old man he befriended attempted to destroy the village, and finds a lead that Gennou is in the mountains behind the village.
