Run Idate Run! Nagi Island Awaits! (走れイダテ!嵐を呼ぶ波乱のナギ島!!, Hashire Idate! Arashi o Yubi Haran no Nagitō!!) is episode 104 of the original Naruto anime.
Aoi taunts Idate and attacks him. Team 7, who are still swimming for the island, are attacked underwater by the Ame ninja. Using the first step of training for the Rasengan, Naruto creates a huge whirlpool that saves them. They then try to rescue Idate, but prove to be no match for Aoi, who poisons them and leaves. Sakura gives them all medicine Tsunade had given her, and they seek shelter in a cave. Idate explains that he was once a Konoha ninja, but was tricked by Aoi into betraying the village after failing the Chūnin Exams.
