The Fourth Holy Grail War commences in Fuyuki City, where seven Masters summon Servants to compete for the Holy Grail.
The Fourth Holy Grail War concludes with Shirou Emiya and Saber winning; however, the Holy Grail is corrupted and causes unexpected consequences.
After the Fourth Holy Grail War, a time loop begins repeating over a span of five days in Fuyuki City, centered around the events involving Bazett Fraga McRemitz and other characters.
Bazett and other characters find themselves caught in the repeating five-day time loop in Fuyuki City, striving to understand and resolve the mystery.
Shirou Emiya begins retaining memories of previous loops, enabling him to investigate the cause and seek a way to break free from the cycle.
It is uncovered that the time loop is a phenomenon created by Avenger (Angra Mainyu) to grant Bazett a peaceful existence and fulfill wishes unachievable in reality.
Shirou and other key characters manage to break the cycle of the time loop, allowing events to progress beyond the repeating five days in Fuyuki City.
