Kō Hyūga

is a shinobi of Konohagakure, and is also a branch member of the Hyūga clan.

Invasion of Pain arc
When Hanabi Hyūga and Hiashi Hyūga were away on a mission, he was assigned as Hinata Hyūga's bodyguard during Pain's attack on the village. When Hinata went to try and help Naruto Uzumaki fight Pain, Kō called her back. He claimed that she would only be a burden to Naruto. Later, he watched in horror with his Byakugan as Hinata went ahead regardless. He was unable to restrain her, due to a broken leg he had sustained when Pain used his Shinra Tensei on the entire village.
