Shisō

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

Abilities
He is able to use the Mysterious Peacock Method and could support Akahoshi's techniques by offering him his chakra reserves. He also managed to kill the third Hoshikage alongside Yotaka, although this most likely happened because they caught him off guard. He could also quickly recognise that he is stalked by someone.

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 Yotaka later found where the meteor is hidden and ran afoul of Naruto Uzumaki 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 Yotaka will be subjected to harsh punishment.
