After losing her parents in a car accident, Okko goes to live in the countryside with her grandmother, who runs a traditional Japanese inn built on top of an ancient spring said to have healing waters. While she goes about her chores and prepares to become the inn's next caretaker, Okko discovers there are ghosts who live there that only she can see – not scary ghosts, but playful child ghosts who keep her company and help her feel less lonely. A sign outside says the spring welcomes all and will reject none, and this is soon put to the test as a string of new guests challenge Okko's ability to be a gracious host. But ultimately Okko discovers that dedicating herself to the happiness of others becomes the key to taking care of herself.

In a tumultuous effort, the Sunagakure ninjas attempt to repel an unforeseen invasion of mysterious armored warriors on the Land of Wind. Shortly afterwards, the same armored troops led by Temujin—a skilled knight of impressive power—ambush Naruto Uzumaki, Sakura Haruno, and Shikamaru Nara, who are on a mission to recover a lost ferret. Naruto and Temujin engage in a fierce fight that ends with both of them falling off a cliff.

Taken aback by their friend's sudden misfortune, Sakura and Shikamaru witness yet another alarming development: a massive moving structure appears out of nowhere, ravaging any trees and rocks in its path. While Sakura sets off to find Naruto, Shikamaru infiltrates the imposing fortress in hopes of learning more about the critical situation. 

Entangled in a relentless conflict, the Konohagakure ninjas join forces with their Sunagakure counterparts to defeat the common enemy. However, amidst the turmoil, a clash between two different visions of an ideal world emerges.

The band "given"—comprised of Ritsuka Uenoyama, Mafuyu Satou, Haruki Nakayama, and Akihiko Kaji—has advanced to the final screening of the Countdown-fes Amateur Contest, in which they will be judged on their live act. Although enthusiastic, they worry about having only one original song to perform.

Mafuyu embraces the idea of learning more about music in order to create new, emotionally resonant songs. In this regard, he unexpectedly receives help from Ugetsu Murata, Akihiko's on-again, off-again lover. Ugetsu has unsuccessfully tried to let go of Akihiko, who himself is torn between lingering feelings for his past and an uncertain resolve for the future.

As the competition draws near, Haruki uncharacteristically begins to doubt his place in the band and the trust he shares with Akihiko. It is a given that not all attachments last forever, but it remains to be seen what can be salvaged from the ruins of heartbreak—or if only regrets will endure.
