|森乃イダテ Morino Idate|
|Anime||Naruto Episode #102|
Idate took the Chūnin Exams, up until the "tenth question". Like any exam ran by Ibiki, those who chose to abandon the exam before the question would have their team disqualified, but can retake it in six months. Idate chose to stay along with his squad. He was part of the remaining participants who would ultimately fail the exam, being accused of sacrificing a squad's future for their own. This failure resulted in the participants stuck as genin for life, never allowed to retake the exam, which left him depressed. When he protested, Ibiki suggested that he was not cut out for being a ninja. Aoi Rokushō told Idate that he could become a chūnin by stealing a secret scroll and the Sword of the Thunder God. After Idate brought the items to Aoi, he asked about becoming a chūnin. Aoi informed Idate that he would be made a chūnin and Aoi made a jōnin in Amegakure, using the sword and scroll as gifts. Therefore, Idate was classified as a fugitive by his home village, and had to go on the run in order to avoid being imprisoned for his theft.
It was not long before Ibiki uncovered Aoi's plan and chased after his little brother. However, Aoi quickly brought in Amegakure allies to capture Ibiki and eliminate the two Anbu members with him. Aoi then tortured Ibiki to read the scroll, in the process accidentally setting the building on fire after Ibiki managed to free both himself and his little brother. However, despite Ibiki's fierce efforts, the flames soon separated the two siblings, and Idate was forced to flee the fire that would (supposedly) kill the two older nin, although they both escaped separately.
At some point after that, Idate tried to steal money from Jirōchō Wasabi and failed, although Jirōchō took pity on him, and let Idate join the Wasabi family after lecturing him, and giving Idate a pocket-knife.
Despite no longer considering himself a ninja, Idate has been shown to still be proficient in basic ninja abilities. He quickly noticed when he was caught in a genjutsu and easily broke through it.
In preparation for an important race, Idate underwent harsh cardio training, using very heavy weights in a similar way to Rock Lee to increase his speed expeditiously. This method proved successful as he was able to easily outpace Team 7, including Sasuke Uchiha who recently underwent extreme speed training himself.
Land of Tea Escort Mission
Three years after leaving Konohagakure, Idate was hired to be the Wasabi family's runner for the Todoroki Shrine Race in the Land of Tea, with Naruto Uzumaki, Sasuke Uchiha, and Sakura Haruno employed as his bodyguards. They first met at a tea house where Idate started flirting with Sakura, much to Naruto's dismay. Then Idate told the waitress that Team 7 would pay the bill. He then ran off wearing ankle weights. Team 7 caught up, but Idate took off his ankle weights and ran off again. This time they couldn't catch up. They later surprisingly met him at Boss Jirōchō's house. Aoi and Team Oboro turned out to be the bodyguards of the opposing Wagarashi family's runner, Fukusuke Hikyakuya.
Their leader, Kyūroku Wagarashi, hired them to take care of Idate for him. And, although Team 7 was constantly angered by Idate, they still protected him at any cost, especially after hearing his tragic story and realising that Ibiki was his older brother. After enduring difficult battles with Team Oboro and Aoi, Team 7 helped him win. When Ibiki came to pick up an injured Sasuke, Idate bowed to him, while Ibiki said that he didn't have the eyes of a coward anymore.
- The name "Idate" may have been based on the Buddhist God, Idaten, a devoted guardian of Buddhist monasteries.
