Fate/Prototype is a reimagined version of Kinoko Nasu's original version of Fate/stay night. The storyline takes place eight years after the tragic Heaven's Feel. Here, the Holy Grail is still the so desired object. However, the darkness under this so-called "Grail" is revealed while the characters proceed to fight against each other in order to win.
