"Pokémon/Grand Order" is a fangame that adapts the story of Fate/Grand Order, using resources from the original game and adjusting them to Pokémon mechanics, based on the Fate system.

Its story is based on the first part of Fate/Grand Order. As the protagonist and the last Master among the 48 who entered Chaldea, the Organization for the Preservation of Human Order, your mission is to restore human history by eliminating chronological irregularities—anomalous regions in the timeline created by King Solomon to destroy humanity's future.
