Her leg becomes stiff during PE class, where they practice for the marathon tomorrow, with Akiko bringing her to the clinic afterward.

Norimasa tries to comfort Kanna in the ensuing rain, but she gets upset, running away back towards Ushijima Shrine.

Shiro then urges Kanna to return to Ushijima Shrine, telling her to overcome her fear of the god.

Yasha challenges her in a race, which he wins, boasting that he can bring all of the offerings to Izumo in time before Shiro urges him that Kanna is the one who was asked to do so.

They stop by Lake Suwa in Nagano at a location of Suwa-taisha Shrine next to it, where they meet the powerful Ryūjin, the dragon god and a son of Ōkuninushi.

Kanna lies that she is to bring the feast offerings to Izumo, angering Ryūjin, who urges her to tell the truth.

Ryūjin understands her, relating to it by explaining that he had to sign a contract that bounded him to rule Lake Suwa, meaning that he could never see his father again, just like how Kanna can no longer see her mother after she died.

Kanna told Yasha about her mom's death from an illness after losing the marathon, because she wasn't fast enough and blames herself for it.

As they went to sleep, Kanna suddenly hears her mother's voice and follows it to a secluded beach, where she is happy to see her, body and soul.

The fake Yayoi distorts her vision, under an evil aura, depicting Shiro and Yasha to her as terrifying monsters to prevent her from listening to their pleas.

After what happened with the fake Yayoi, Shiro reveals to Yasha that the modern world has become cruel, with the dark side of the people emerging from them.

After the vision, Kanna suddenly regains her lost passion for running, realizing that Yayoi was a descendant of the Idaten, who undertook the annual quest before tying up her hair with the torn bracelet.

She motivates herself amid a group of people on the beach in Izumo during the typhoon, believing that she could still communicate with Shiro and Yasha, when in fact, she couldn't, after ripping off the bracelet.

Ōkuninushi thanks Kanna, Shiro, and Yasha, for their undertaking of the quest assigned to the Idaten, taking them back to the entrance of the shrine he rules over.

Spring arrives, and Kanna, who has moved on ever since Yayoi's death, goes out of her apartment to take a run outside on the riverwalk, training herself for what's to come in the future.

The film was first revealed and funded through a series of three crowdfunding campaigns by Cretica Universal, which ran from March 27, 2019, to June 1, 2020.
