After Hashirama and Madara joined the battle, the balance shifted.
Hashirama's method of shaving away the energy sphere with his wooden sword forced Momoshiki to spend roughly three breaths readjusting Takamimusubinokami's convergence mode. During those three breaths, Madara had already found a structural weakness near the root of the summoned beast's left foreleg—the gaps between the layers of shell there were about a sheet of paper wider than elsewhere. When the tips of Madara's Chakra claws pierced that gap, a crack over two inches long split open across the dark shell. What seeped from it was not blood, but dark energy that erupted like high-pressure steam.
After that puncture, the summoned beast's body shuddered for about half a breath. Its four feet tore free of the earth before slamming back down, and the energy gathering within the crack on its face was interrupted for nearly one breath before resuming.
Taking advantage of that half-breath tremor, Naruto condensed another Rasenshuriken. This time, he did not aim for Kinshiki, instead hurling it directly at the ground between Kinshiki and Momoshiki—the Rasenshuriken broke apart and reformed before striking the ground into three separate streams of Chakra. One blocked Kinshiki's path toward Momoshiki, one exploded into a layer of golden light across the ground before Momoshiki's feet, obscuring his vision, and the third skimmed past the edge of the summoned beast's facial crack, shearing off three of the serrated protrusions that were reforming around it.
At the same moment the light screen erupted, Sasuke activated Amenotejikara. His body vanished from its original position for roughly one-fifth of a breath, and when he reappeared, he was already two steps to Momoshiki's left, at the end of a prearranged path. The tip of the Kusanagi Sword was less than a palm's breadth from the outer edge
