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.

Velonica has crossed the entire galaxy from the distant planet of Metrotopia and landed on Earth. Her mission is simple: to meet with Earth's leader and complete a contract that will allow them to install a giant antenna and connect Earth to the Galaxy Network. Soon upon her arrival, Velonica discovers that Earth does not have a single leader, and its inhabitants are preoccupied with strange, illogical activities. But before her father—the President of the Galaxy Network—intervenes, Velonica must find a way to make sense of this backwater planet.

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.

Led by Kakashi Hatake, Naruto Uzumaki, Sakura Haruno, and Rock Lee are tasked to escort the extravagant Prince Michiru Tsuki and his spoiled son Hikaru to the prosperous Land of Moon when the two return from a long trip around the world. As if guarding two whimsical high-ranked individuals was not challenging enough, the prince's reckless decision to acquire an entire circus during their journey—mainly to entertain Hikaru's wish of owning the saber-toothed tiger featured in the show—further propels the mission into disarray. Just as things are finally settling down, the arrival of Michiru's convoy at the Land of Moon is met with an unforeseen crisis—the greedy Chief Minister Shabadaba has taken over the country with the assistance of mysterious, powerful ninjas. While Kakashi's team relentlessly fights the enemy by any means necessary, the two princes are forced to confront a new outlook on life through adversity.
