Naruto Episode 23
Upon arriving at the location of the first part of the exams, Team 7 meets with Team 10 members Ino Yamanaka, Shikamaru Nara, and Choji Akimichi, as well as Team 8 members Shino Aburame, Hinata Hyuga, and Kiba Inuzuka. The group is befriended by exam veteran Kabuto Yakushi, who offers the nine information on their competitors. His remarks about the Land of Sound, however, touch a nerve with the Sound Genin present, and is attacked as such. Before the fight can progress, Ibiki Morino and several Chunin appear.
