In August, 1918, Matsuura Ito lives in a coastal village of Toyama with her husband and three children. During the summer, there wasn't much fish to catch, so her husband has been far away from home to catch fish. To support herself and her children, Ito carries goods from ships like the other women in the village. Meanwhile, the residents encounter rising prices for rice. The women are unable to feed their family due to the high prices of rice. The women ask a nearby rice store to sell rice at lower prices, but it fails. The price of rice continues to rise daily. Due to an incident, Ito and the other village women step up to the plate.
Tasked with preventing the destruction of humanity, the Chaldea Security Organization observes an anomaly: the Near-Future Observation Lens: Sheba proved the extinction of humanity in 2019. Chaldea pinpoints space-time Singularities thought to be the cause of humanity’s extinction and executes a forbidden ceremony called Rayshifting, where mages are converted into Spiritrons and sent into the past to restore humanity. Under the command of Romani Archaman and with the aid of numerous Servants, Ritsuka Fujimaru and Mash Kyrielight begin by restoring Singularity F: Flame Contaminated City, Fuyuki. From there, they make their way through seven Singularities, resolving each of them. And now, the path to the Final Singularity, Grand Temple of Time: Solomon, lies open, and the final battle against the King of Mages is underway.
