In search of a mystical ingredient known as Sky Fish, Meliodas and Hawk stumble upon a spring that suddenly transports them to the Sky Temple: a breathtaking land above the clouds, inhabited by beings called Celestials. Meliodas, however, looks strikingly similar to a local criminal called Solaad, and is imprisoned and shunned as a result. Meanwhile, the kingdom of the Sky Temple prepares to defend the Great Oshiro's seal—said to harbour a three thousand-year-old evil—from the malevolent Six Knights of Black, a group of demons who seek to destroy the seal. However, the Demon Clan is successfully unleashed and terrorizes the land, prompting the remaining Seven Deadly Sins and the Celestials to fight against their wicked foes. The battle progresses well, until one of the Six Knights awakens an Indura of Retribution, an uncontrollable beast from the Demon Realm. With its overwhelming strength and sinister power, the Seven Deadly Sins and Celestial beings must now work together to defeat the creature that threatens their very existence.

It has been two and a half years since Naruto Uzumaki left Konohagakure, the Hidden Leaf Village, for intense training following events which fueled his desire to be stronger. Now Akatsuki, the mysterious organization of elite rogue ninja, is closing in on their grand plan which may threaten the safety of the entire shinobi world. Although Naruto is older and sinister events loom on the horizon, he has changed little in personality—still rambunctious and childish—though he is now far more confident and possesses an even greater determination to protect his friends and home. Come whatever may, Naruto will carry on with the fight for what is important to him, even at the expense of his own body, in the continuation of the saga about the boy who wishes to become Hokage.

Unleashing a devastating surprise attack, flying ninjas from the Land of Sky are seeking revenge against their old enemy Konohagakure. Despite his eagerness to join the fight, Naruto Uzumaki is held up by Shinnou, a mysterious doctor who requires his assistance to save an injured person. While delivering the wounded man to the hospital, Naruto has an unexpected encounter with Amaru—a stormy youngster from a neighboring village desperately looking for Shinnou's help. Meanwhile, as the invaders withdraw to restore their forces, Tsunade seizes the opportunity to dispatch a small team including Sai, Shikamaru Nara, and Kakashi Hatake to strike down their base. Simultaneously, she commissions Naruto, Sakura Haruno, and Hinata Hyuuga to accompany Shinnou and Amaru on their journey. During this time, however, Orochimaru has his own schemes: he orders Sasuke Uchiha to bring him the doctor who specializes in the reincarnation technique. As the escort group accidentally uncovers the sinister truth behind the attacks, tumultuous plans are set in motion. But even when confronted with an unforeseen reunion, Naruto does not waver in his endeavor to end the warfare and its disastrous effects.

A group of ninja is planning to revive a powerful demon, and once its spirit is reunited with its body, the world will be destroyed. The only way to prevent this from happening is for Shion, a shrine maiden, to seal it away for good. Naruto Uzumaki is tasked to guard her, but one thing stops Shion from accepting his help: she also has the ability to predict death—and she has foreseen his demise approaching soon. In order to escape his fate, Naruto must stay away from Shion; however, undeterred, he chooses to challenge the prophecy in order to protect Shion and the world.
