Main Characters (6)
Summary
The Amegakure prisoner Jiraiya seized is handed to Ibiki for questioning, while Shizune takes charge of examining the captured Pain. Hoping to read the Sage's final coded message, Shikamaru brings it to Konoha's Cryptanalysis Team, who determine that the cipher cannot be cracked without a key only someone genuinely close to Jiraiya would recognise.
Key Events
Once the search narrows, it becomes clear that Naruto is the single person who might supply that key. Still crushed by his master's death, though, he cannot bring himself to concentrate on the puzzle.
Shikamaru takes him along on a visit to the pregnant Kurenai and reminds Naruto that he too has buried a teacher in Asuma. Grief cannot be allowed to stall them, he argues, because their duty is to grow into shinobi worthy of the masters they lost. The words begin to steady Naruto and pull him back toward the task at hand.
