With their latest mission complete, it's time once again for the group to go back to mediocre missions. After all are done, Konohamaru and his friends pay a visit to Naruto. All which result in being chased by Sakura. Everyone is soon over though, as two mysterious ninja block their way, and one of them isn't too happy with Konohamaru. Sasuke arrives to save the day, but the leader of the group shows up, with stealth skills that surprise even Sasuke. Meanwhile, the Third Hokage announces that it's time once again for the Chuunin selection exams.

After the three ninjas take their leave, Sasuke realizes he has a powerful rival out there. The next day, Kakashi announces that he has recommended all of them for the Chuunin Exams. While Naruto and Sasuke are pleased, Sakura is afraid of letting everyone down. Also, someone decides they aren't ready and decides to test their abilities.

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?
