Konohagakure hosts a special tournament for ninjas of all ranks, stirring up fervor among the rookies who are eager to prove themselves in a competition against their superiors. Additionally, the winner is granted the opportunity to create their own village decree! Despite his enthusiasm to claim the prize, Naruto Uzumaki fails to focus on the game's objective as he becomes obsessed with confronting his teacher, Kakashi Hatake, in single combat.

The Seven Deadly Sins, along with Elizabeth Liones and Hawk, have won the Kingdom of Leones back from the Holy Knights. At long last, it's their time to indulge in the peaceful lives they fought for. From inedible meat pies, overdue battles, unexpected stalkers, and the butterflies of first love, the Sins are accompanied by their friends in their carefree, fun-filled time together. However, the calm is broken with the premonition of a new threat, bringing upon the signs of Holy War and threatening to shatter the peace of the Sins' easygoing days.

As the Fourth Great Ninja War quickly approaches, Sunagakure hosts a special Chunin exam to strengthen the troops of the Allied Shinobi Forces. Among the participants are Konohamaru Sarutobi, an ambitious rookie, and Naruto Uzumaki, who has become a renowned ninja. Despite the significant disparity in skill, Konohamaru is excited at the prospect of proving himself in a competition against Naruto—the one person he both admires and sees as his rival.

After being sent to investigate the alarming disappearance of four bloodline limit-wielding ninjas from different countries, Kakashi Hatake, Naruto Uzumaki, Sakura Haruno, and Sai successfully discover their whereabouts and inform the Hokage. Unexpectedly, Tsunade's further arrangements fall apart when Hiruko—the mastermind behind the incident and also a former Konohagakure ninja obsessed with power—appears to announce that he has absorbed the missing ninjas' unique abilities. On the verge of becoming invincible, he seeks one more bloodline limit before starting an all-out war to take over the world. As Konohagakure's past connections with Hiruko raise suspicions among the nations about its involvement in the affair, Tsunade receives an ultimatum to solve the crisis. Left with no other choice, she decides to follow Kakashi's lead after he presents a daring yet salutary scheme—a proposal that could send him to certain death. However, Naruto opposes such a plan! Despite the Hokage's decision, he is determined to save his teacher's life, even if it means fighting friend and foe alike.
