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…。

木葉丸是第三代火影的孫子，為了證明自己的實力，並擺脫火影孫兒的名號，木葉丸無時無刻都在計劃著如何打敗自己的爺爺，好讓大家認同他的實力，只不過每次都是以失敗收場。後來他打算當鳴人的徒弟，好學會色誘之術，只不過怎麼學都學不好，後來他發現其實就算想當傑出的忍者，還是得靠自己努力，便打消了當鳴人徒弟的念頭，決定靠自己努力好好學習忍術…。

鳴人一直都很喜歡小櫻、只可惜小櫻的心上人是佐助。鳴人為了一親芳澤，趁機偷襲佐助，兩人打了起來，結果佐助因一時大意被鳴人綁架，爾後鳴人偽裝成佐助去接近小櫻，剛開始的確進行得還蠻順利的，只不過鳴人早上喝了過期很久的牛奶，總是在緊要關頭拉肚子，所以最後還是沒有得逞…。

卡卡西擔任鳴人他們那一組的上忍老師，雖然一開始就上了鳴人的當，不過接下來鳴人就沒有好日子過了，除非他們三個人能拿到卡卡西身上的兩個鈴鐺，否則就不能吃午餐，當然也不能通過考試。鳴人為了吃午餐與通過考試，使出了混身解數，還是沒有辦法打敗卡卡西，就在鳴人中了卡卡西設下的陷阱時，佐助也開始採取行動…。

剛開始由於鳴人他們的各別行動，使得卡卡西說出要他們放棄當忍者的判斷，經過卡卡西的一番訓誡之後，鳴人他們才懂得團隊精神的重要性，當他們通過卡卡西的考驗之後，便成為卡卡西手下第一批過關的忍者…。

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.

Kakashi prepares to stop Zabuza once and for all, but Haku has other plans. Zabuza's employer shows up and he's decided to take matters into his own hands...

Zabuza is no longer Kakashi's enemy, and thanks to a little speech by Naruto about how ninja are, Zabuza takes on Gato's men single handedly. The Demon of the Hidden Mist takes his vengeance on Gato and all of those dumb enough to follow him, and apologizes to Haku for what he did to the kind little boy. After the group takes care of the rest of Gato's men, Zabuza asks Kakashi one final request, to see Haku one final time. This is Zabuza's requiem.

Rock Lee challenges Sasuke to a one-on-one fight. Naruto grows angry and attacks him, only to be beaten in one attack. Sasuke realizes the challenge and eagerly accepts. But will Sasuke be defeated just as easily by this mysterious ninja? Sasuke's only advantage seems to be his Sharingan, but what happens when not even that will work?

A reunion of all the rookies isn't a very happy one, as all of them prepare to take the Chuunin Exam. With so many rivals around, Naruto's team will need help from a fellow ninja named Kabuto to know what they're up against. Will the group be able to last through the exam?

The first test of the Chuunin Exam is just that, a written test. When Ibiki issues a strict set of rules, Naruto fails to realize that the objective of the test is to cheat without getting caught. Can Naruto realize the truth before time runs out? And what about the tenth question?

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?

Konohamaru, the grandson of Leaf Village’s Third Hokage, shows up at the Chunin Exam site. He comes along with Moegi and Udon to cover the events for the Ninja Academy’s school newspaper. Konohamaru looks up to Naruto like an older brother and through interviews with the characters, recaps their adventures thus far.

The second exam is about to begin, and every ninja must sign a form so that their team can get either the Heaven or Earth Scroll. The goal is to get one of each scroll and make it to the tower in five days. The groups get their scrolls and the exam begins. Naruto is ambushed by a ninja who poses as him. This ninja doesn't fool Sasuke, who immediately figures it out. Meanwhile, a new foe seeks them out, but who is this foe?

To prevent further problems, Sasuke thinks up a password to determine friend from foe, but will it be that simple? Meanwhile Naruto has his hands full with a giant snake. Can he handle this on his own and what about Sasuke and Sakura, can they survive the ordeal?

Sasuke is about to give up and give their scroll to the enemy, when Naruto stops him and accuses him of being a fake. Naruto then turns his attention to the Grass Ninja.... The battle is intense and when the Grass Ninja appears to get the upper hand, can Sasuke muster up the courage to fight?

Sasuke is still stuck in his trance and even Sakura's pleas can't get him back to normal. Meanwhile, Anko searches for the grass ninja fake. When the team appear to get the upper hand the question begs to be asked. Are the ninja truly defeated, or is there more to them than meets the eye?

Since Sakura was the only one who did not get injured in the previous battle she must watch over and protect her teammates. Unknown to her though, there are enemies watching from the trees.... They attack, but a friend arrives to help. Will it be enough?

Lee in his weakened state is having trouble defeating Dosu. Sakura realises everyone has been protecting her until now and that its her time to protect them! Can Sakura succeed where even Lee failed?

With Sakura defeated and facing certain death, more reinforcements step into the fray. However, they sense an even bigger level of power, and its not coming from the sound trio! Meanwhile Sasuke wakes up with an ominous dark aura surrounding him and the mysterious seal spreading over his body. He has but one goal....make his enemies pay!

Kiba, Shino, and Hinata decide to try and eliminate their opponents by taking more scrolls. They arrive upon a battlefield where three Rain ninjas are battling Gaara, Kankuro, and Temari. They remain hidden and observe the battle, thinking one of the Rain ninjas is a dangerous foe. After realizing Gaara's amazing abilities, they discover who is the really the dangerous one, and will be lucky if they can sneak away with their lives!

To heal their wounds, Naruto and his team take a much-needed rest after their battle against the Sound ninja. But it has already been four days since the start of the exam and there is only one day remaining until time expires.

Naruto's team joins Kabuto on their journey to the tower, but on the way, they are trapped by the genjutsu (illusion technique) of the Hidden Rain Village's genin (low rank ninja), Oboro's team.

The exam is over, but did they truly pass? An old friend arrives to explain and show his concern. Meanwhile, Anko informs the ANBU about Orochimaru, the S-Class criminal who even they cannot stop. Later the Third Hokage explains to everyone what the third exam truly means....

With so many participants still left, the groups are told that they will be pitted against each other in preliminary matches. Kabuto leaves, then Sasuke is told he has to fight. They know that Sasuke was given the cursed seal and if it takes over they will stop him. Can Sasuke stop the seal from taking over again and still win?

Unable to use his chakra against Akado, Sasuke has to rely on good old-fashioned taijutsu to defeat him. Kakashi senses something is wrong with Sasuke and takes him away after the match.

While Shino and Zaku finish their fight, Kakashi works on Sasuke's cursed seal. However, someone sinister shows up to ruin things, will Kakashi be able to protect Sasuke from this skilled foe?

The match between Kiba and Naruto kicks off, with Kiba immediately proving he has the upper hand in the battle. Everyone still believes Naruto is the weak ninja he's always been, everyone except for Hinata, Kakashi, and Sakura. Now it's Naruto's time to shine, and this time...everyone will be watching him!

The battle between Naruto and Kiba draws to a close, with each of them giving it everything they've got. After being tricked by Naruto, Kiba can no longer rely on Akamaru's help. Naruto decides now is the time to release his new jutsu, only Kiba won't give him time to prepare it!

Kiba alerts Hinata, as he's being taken away, that there are only a few fighters left. He warns her that if she fights Gaara, she has to give up immediately or she could be killed. He also tells her to give up if paired against Neji, because Neji already has issues with her. Just then, the board shows the next fight...Hinata vs. Neji. Just how far will Hinata go to prove herself?

Hinata will not give up so easily, especially with Naruto watching her. Will Hinata be willing to give up her own life in order to prove herself, or will the match be stopped before Neji can connect a killing move?

The second-to-last match finally arrives! Rock Lee must face down the mysterious and dangerous Gaara, a ninja who is said to have never been truly injured in a fight before.

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.

The match between Gaara and Lee draws to an end as Lee unleashes his ultimate move. But will even this be enough to defeat Gaara? Even if Lee does make it out in one piece, even more shocking news awaits him.

As Chouji faces off against Dosu, Orochimaru gives an order for Kabuto to abduct Sasuke. He also tells Kabuto that if he wants to stop him, he'll have to kill Sasuke. As Kabuto approaches Sasuke, he hesitates on what to do. His spy cover is soon blown though, as Kakashi appears on the scene. Will Kakashi save Sasuke from Kabuto's grasp?

Naruto wants Kakashi to train him, but Kakashi has other plans. Ebisu arrives to an unhappy Naruto and makes a deal with him. If Naruto can get away from Ebisu, he'll make Kakashi train him. Naruto decides to accept Ebisu's challenge, but can he win?
