After the events of Megadimension, the CPU's and CPU Candidates went back to their normal lives which occasionally included meetings with the Gold Third. However, one day, Histoire received a call from a different oracle from another dimension. This call was to alert Histoire of an issue between dimensions which would switch the candidates around. Unbeknownst to them, this was actually a trick created by someone... what will the CPU's from both dimensions do as well as the candidates?
