A Wall Too High…!! (高すぎる壁…!!, Takasugiru Kabe…!!) is chapter 71 of the original Naruto manga.
Sakura and Ino think back on their childhoods together and how, when they amicably ended their friendship, they agreed they would become rivals that would not show each other any sympathies. Intending to stay true to their promise, both relocate their forehead protectors to their forehead, removing any possibility of mercy by fighting as Konoha ninja and not old friends. The two exchange blows and Sakura punches Ino in the face, making Ino happy that Sakura is taking things seriously.
