Yotaka

is a ninja from Hoshigakure. He and Shisō worked under Akahoshi.

Hoshigakure 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 Shisō and Yotaka to fetch the Konoha ninja to help Akahoshi fight Natsuhi.

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