Six-Tailed Beast arc
Akaboshi, Chūshin, Nangō, and Benten make for Mount Katsunagi in search of the Tsuchigumo clan's kinjutsu. They manage to destroy the barrier around the mountain and make their way up. While climbing, Chūshin is almost pushed off the cliff, but he managed to recover and continue. They could not find the jutsu anywhere and ran into Tonbee, whom the group defeated quickly. They discover that Hotaru has the jutsu and they begin searching for her.
