Holy Potato War

The Holy Potato War ( 聖ポテト戦争, Hijiri poteto sensō ?) is the competition that decides the ownership of the Golden Potato through intense battle royale.



The war of the Steam is unique, as it is the only one that has a Servant system that uses Potato Gods as familiars. It is to be noted that the war of the Steam is apparently not the only "war of the Golden Potato", as there seems to be several artifacts labeled as the Golden Potato and different competitions for their ownership.
