I totally felt a lump in my throat when Naruto finally found his name in Jiraiya's book; it wasn't just a nod, it was like Jiraiya was saying he believed in him right up to the end, which just makes me think about how much that's gonna fuel Naruto going forward. It's so sad that this novel is the last tangible piece he has of his sensei, but I bet he’ll cherish it forever.
