Kou Hyuuga

Kou Hyuuga (日向コウ, Hyuuga Kou) is a shinobi of Konohagakure and a branch member of the Hyuuga clan. He is the protector of Hinata when Pain attacked Konoha, because Hanabi and Hiashi Hyuuga were away on a mission. As Hinata tried to help Naruto, Kou called her back claiming that she would only be a burden to him. Later, he watched in horror with his Byakugan as Hinata went ahead anyway. He was unable to restrain her due to a broken leg he had sustained when Pain used his Shinra Tensei on the entire village.
