[Original Web Manga](https://ganma.jp/otometetsugaku)

The stage: the city of Snowfield in the western U.S., far from Fuyuki. There, a "false Holy Grail War", quite unlike the original Holy Grail War, unfolds. There were those who had been keeping an eye on the auguries of the Holy Grail in Snowfield. According to an investigation by the Mage's Association, the Holy Grail War system in Snowfield was an imitation of the one in Fuyuki. What's more, the system was incomplete, leading to the exclusion of one of the seven classes and the selection of beings as Servants who ordinarily could not be summoned. It was, verily, a strange fake. As an organ of the U.S. government executes its various plots, the Servants are summoned one after another...

Remake of the Imperial Grail War from the Koha-Ace manga. The protagonist is Akagi Kanata, who gets transported 75 years to the past to participate in a Holy Grail War in the midst of World War 2.
