At [[Mount Myōboku]], [[Naruto]] asks to train with [[shadow clone]]s to help his learn [[senjutsu]] faster. [[Fukasaku]] agrees, but they do not help much. Seeing that Naruto is having trouble, Fukasaku informs him that not everyone can learn senjutsu; only those with large [[chakra]] reserves and the determination to never give up can do so. Naruto is happy to find he has plenty of both. Meanwhile, [[Karin]] heals [[Sasuke]]'s injuries while the rest of [[Taka]] fights with [[Killer B]]. Seeing that they might actually be a challenge, B decides to go all out.
