Arc 21Worlds Collide
Sakura Haruno defeated Obito and helped Konoha Sasuke confront his vengeful counterpart before she and Sasuke from another world shared knowledge of the coming threat. Back in their own Konoha, Sakura learned new techniques and she and Sasuke began planning another journey through time to investigate the Masked Man.
- Sakura Haruno fought Obito with her giant constructs and ice techniques, survived his fatal strike with an Ice Clone, and defeated him after he exhausted his chakra and stamina.
- After witnessing Sakura Haruno's apparent death, the missing-nin Sasuke awakened his Mangekyō Sharingan, but Konoha Sasuke defeated him and urged him to abandon revenge before Obito escaped with Sasuke and Karin.
- Kakashi, Naruto, and Sakura reached the battlefield, where Sasuke declared his intent to avenge the Uchiha Clan, while Sakura Haruno challenged him and introduced herself as a visitor from another world.
- Sakura Haruno and Sasuke explained their world and their battles to Kakashi's group, and Sakura Haruno revealed that she had killed Shimura Danzō before the group returned to Konoha.
- Sakura Haruno warned Konoha about Pain and told Tsunade that she and Sasuke had traveled through time using the ley-line energy in Rōran's ruins, while Sakura learned Cherry Blossom Impact and Nintaijutsu from her counterpart.
- Sakura visited Yugao and Hinata, then learned that Sasuke was investigating Sai's past and considering how to bring him back from Root.
- Sakura and Sasuke suspected the Masked Man had controlled the Nine-Tails during its attack and planned to return to that night through the Rōran Ruins when the ley-line energy recovered.
- Sakura suggested waiting for Naruto to join their next journey, while Sasuke asked about a future version of himself and Sakura kept the answer secret before they parted.
