@Luffyxnaruto:
The only thing I could think of is losing Sasuke fugitively.
IF this is the case… I would facepalm so hard my brain would transcend to another dimension.
@Luffyxnaruto:
What convenience bombs?
Jiraiya was conveniently the 4th's teacher who WROTE A BOOK ON NARUTO, and actually knew about him a long time ago, and he just so happens to be the toad sage.
Why is that strange? Let's look at his Team: Tsunade, Jiraiya, Orochimaru. 3 sages just so happen to train team 7, and Sasuke ends up betraying the village like orochimaru.
AND THEN we find out that Naruto and Sasuke the two rivals are relatives to TWO FAMOUS Rivals.
What are the freaking odds of that?
Let's not forget the Akatsuki waiting 3 years before targeting Naruto again. (who was easy pickings at that point)
And then there's this war, Edo Tensei revives a butt load of ninjas, and where do they end up? Right next to their friends, families and rivals of course!
Oh man, oh man, Kabuto is just that unlucky.
Uchiha Madara's plan included Nagato reviving him; A boy who he probably shouldn't even have known about since he's been stuck underground since god knows when.
And then Obito magically falls in his whereabouts?
Don't get me wrong, a LOT of manga do this, but everything is falling into place so well "Because Destiny repeats itself" that it makes me chuckle a bit.
