"The Pair's Growth!!" (二人の成長!!, Futari no Seichō!!, Viz: My, How They've Grown!!) is chapter 246 of the original Naruto manga.
Naruto and Sakura must once again take one of two bells from Kakashi. Since there are only two of them this time (a fact that devastates Naruto and Sakura), there are no underlying lessons of teamwork. Because Naruto and Sakura are no longer fresh genin, Kakashi does not read his new Icha Icha Tactics book and immediately uncovers his Sharingan. Naruto once again attacks before being given permission, though he is not as easily subdued by Kakashi this time. The contest continues into the night but Naruto and Sakura cannot get close enough to Kakashi. Naruto opts for a trick; he threatens to spoil the ending of Icha Icha Tactics, forcing Kakashi to shut his ears to avoid hearing it and his eyes to avoid reading Naruto's lips. This creates an opening for Naruto and Sakura to take a bell.
