Naruto. Volume 2: Masashi Kishimoto

Naruto is a ninja-in-training with a need for attention, a knack for mischief, and sealed within him, a strange, formidable power. His antics amuse his instructor Kakashi and irritate his teammates, intense Sasuke and witty Sakura, but Naruto is serious about becoming the greatest ninja in the village of Konohagakure!
Naruto, Sasuke and Sakura have passed the final test to become junior ninja - but now the real challenge begins. Tired of menial tasks, the young ninja ask for a tougher assignment and find themselves - together with their teacher, Kakashi - bodyguarding a cranky old man from the Land of the Waves. But Tazuna the bridgebuilder is in more danger than anyone realizes: he`s the target of elite ninja assassins, including Zabuza, `the demon,` and our heroes are about to face a trial by fire...
