Hidden Star Village arc
They both assisted Akahoshi the assassination of the Third Hoshikage. When the Leaf Ninja were summoned to Hoshigakure to protect the meteor, Rock Lee and Tenten were suspicious of them and did a stakeout until being discovered. After Akahoshi kidnapped Sumaru, he sent Shiso and Yotaka to fetch the Leaf Ninja to help Akahoshi fight Natsuhi.

He, Akahoshi, and Yotaka later found where the meteor is hidden and ran afoul of Naruto Uzumaki and Natsuhi. Akahoshi absorbed the chakra of Shiso and Yotaka. Shiso and Yotaka recovered after Akahoshi recovered the star. Shiso and Yotaka tried to get Akahoshi to give up, but Akahoshi ignored them. When Akahoshi fused with the star, Shiso and Yotaka were among those hit by Akahoshi's out of control chakra. After Akahoshi was defeated, Tsunade mentioned that he, Akahoshi, and Yotaka will be subjected to harsh punishment.
