The Kaguya Ōtsutsuki Strikes arc is the final major storyline of the Naruto: Shippūden series, spanning manga chapters 678–700 (Volumes 70–72). It features Team 7 fighting to save the world from an ancient, alien progenitor of chakra named Kaguya Ōtsutsuki
The battle between Team 7 (Naruto, Sasuke, Sakura, and Kakashi) alongside Obito and Kaguya was an exhausting, multi-dimensional war of attrition. Kaguya constantly warped the group into distinct environments (like lava and acid realms). Ultimately, Obito used Kamui to locate Sasuke and sacrifice himself, granting Kakashi the Double Mangekyō Sharingan to land the final sealing blow alongside Naruto and Sasuke. As Kaguya regained control and tried to escape into the sky using portals, Kakashi and Obito used Obito’s Kamui to intercept her from the air, allowing Sakura to land a devastating, chakra-enhanced punch to Kaguya's head. With Kaguya disoriented from Sakura's punch, Naruto and Sasuke closed the distance to touch her. They successfully activated the Six Paths — Chibaku Tensei seal bestowed upon them by the Sage of Six Paths (Hagoromo). This completely stripped her of her god-like chakra and sealed her away alongside Black Zetsu in a newly formed moon, ending the threat.
With Kaguya sealed, the Ninja World is saved, but Sasuke Uchiha reveals his intention to execute the Five Kage and take over the ninja world on his own terms. Naruto and Sasuke fight their final, legendary duel at the Valley of the End, which ends in a draw and finally redeems Sasuke.
