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.

Later, Chūshin and his comrades are seen receiving new orders from an mysterious man. After meeting with their leader, the four-man team encountered Utakata, who single-handedly bested the group until they caught him in their Destructive Barrier Formation technique.

After this, the group headed to the Tsuchigumo Village, where they ambushed Hotaru with the help of the villagers in the hopes of getting the forbidden jutsu. Nangō uses his Earth Release: Mud Body Technique to restrain Hotaru and takes a scroll from her backpack, which he then hands to Akaboshi. The scroll turns out to be a rigged trap, which explodes, allowing Hotaru to escape. Nangō and his team pursue Hotaru, and, just after catching her, are interrupted by Utakata, who claims to have business of his own with Hotaru.

After Utakata escaped with Hotaru, Nangō and the rest of his squad were confronted by their leader, who showed them that Utakata was a Missing-nin from Kirigakure with a bounty of 50 million ryō. Akaboshi asked their leader what they should do, to which he began to muse about.
