This light novel adapts the second Naruto film, following Naruto, Shikamaru, and Sakura on what starts as a routine mission to recover a lost pet ferret before Temujin, a mysterious armored fighter, ambushes them and scatters the group. Naruto is blasted off a cliff locked in combat with Temujin, while Shikamaru infiltrates a colossal moving fortress and stumbles onto its connection to the Stone of Gelel, a mineral said to hold power beyond chakra.
