Naruto, Neji, and Tenten are sent by Tsunade to the Land of Birds to investigate reports of a ghost, Noroimusha, terrorizing the local population. Upon arriving, they learn that the daimyō has died, and that his son, the successor, cares little about his duties due to the recent death of his sister. Later that evening, the Konoha ninja encounter Noroimusha and give chase. After cornering it, however, an examination by Neji's Byakugan makes the group realize that the armor the Noroimusha is wearing is empty.
