In the beginning of the Chuunin Exams, Naruto describes Ino as another annoying Sasuke fan. During the preliminary matches, Ino was surprise when Naruto defeats Kiba and said, "Who would have thought Naruto won the match?".
During Ino's fight with Sakura in the prelimenary matches of the Chūnin Exam, Ino muttered on about how annoying Naruto was as she was in Sakura's mind. With the help of Naruto's voice, Ino was thrown out of her opponent's mind and the battle was later shown to be a tie.

Among the Fans
NaruIno isn't overly popular among the fans, but it still has a small number of supporters. They likely support it due to the similar hotheadedness the two have, as well as their similar appearances. Their rival couples are NaruHina, NaruSaku, SaiIno, and ShikaIno.
