昔日有一妖狐作祟，此狐有九尾，狐動其尾其山崩落、海嘯起，百姓不堪其擾，召集村中所有忍者，其中有一忍者奮力對抗將妖狐封印，最後也力盡而亡，此忍者即為第四代火影。木葉村盛傳鳴人即為妖狐，雖然村中有絕對不能說的規定，但大家仍然對鳴人採取敬而遠之的態度，這種態度也影響到村裡的小孩。不受重視的鳴人，只好以惡作劇的方式引起大家注意，只不過結果總是適得其反，還好學校的老師伊魯卡真心相待，而第三代火影也很體諒鳴人心中的苦楚，常常替鳴人的惡作劇善後…。雖然如此，鳴人還是受奸人所利用，偷盜封印之書，還好伊魯卡及時相救，總算沒有釀成大錯…。

鳴人他們終於開始執行正式的任務，只不過首次出任務，竟然是為了去抓一隻走失的寵物貓，鳴人為此極為不平衡，後來在他的極力爭取之下，總算接到了Ｃ級的任務，雖然是Ｃ級，卻也在過程中遇到了非常驚險的意外，遇到了中忍級別的忍者,連卡卡西都覺得不太對勁，甚至懷疑起對方行刺的對象到底是他們負責護衛的老頭子，還是另有他人…？而鳴人在面對敵人時非常害怕,不但受傷,還被佐助嘲笑,鳴人因此下定決心不再恐懼.

Naruto has a dangerous encounter with Haku in the forest, but is Haku there to cause trouble? Naruto and Sasuke better complete their training, as Zabuza is alive and has returned for round 2. Will Kakashi, Sasuke, and Sakura be able to defeat the Demon of the Mist? And, can Naruto arrive in time to help out?

Naruto and Sasuke continue to fight Haku and are getting beaten bad. After having Naruto try and escape a few times, Sasuke begins to see a pattern. Meanwhile, outside Kakashi and Zabuza begin their fight. Can Naruto and Sasuke escape from Haku's jutsu? What plan does Zabuza have to defeat the Sharingan?

As time ticks away, Naruto's only hope of passing the test lies in the final question. However, there is a requirement to answering the final question. If you choose not to answer it, you fail the test and can try again next time. But, if you choose to answer it and get it wrong, you can never take the test again and must stay a Genin forever! What will Naruto's choice be?

Sakura and Ino prepare to settle the score once and for all! However, when Sakura becomes the victim of Ino's Mind-Body Switch Justu, will she be forced to give up the match?

As the battle between Lee and Gaara continues, Gai remembers how hard Lee used to train and how Lee has pretty much no ninjutsu or genjutsu skills. Lee is also a dropout, like Naruto. In order to defeat Gaara, Lee will have to use the move Gai forbade him to use.

Overjoyed at his success, Naruto manages to enrage Gamabunta. With him not willing to accept that Naruto was able to summon him, Naruto challenges Gamabunta to accept him as his subordinate if he is able to stay on his back until sundown.

Naruto, Sakura, Shikamaru, and Pakkun are being chased down by several Sound ninja. Shikamaru decides to stop and try to hold them off so the others can catch up to Sasuke without fear of pursuit. Shikamaru is the logical choice because of his Shadow Possession Jutsu...needless to say, Shikamaru's not too thrilled by this.

As Sasuke is about to be defeated, Naruto and Sakura show up to save him. With this Gaara begins to have flashbacks of his childhood. What happened in Gaara's past to make him experience so much suffering?

As the war draws to a close, Gaara admits his defeat to Naruto, and Orochimaru is forced to retreat as Sarutobi took away his arms. Now, all of the Konoha shinobi gather together to pay their respects to the person whom they respected the most...Sarutobi, the Third Hokage.
