Fate/Grand Order: First Order

Set in 2015, the Chaldea Security Organization emerges to safeguard human history amidst the waning of magecraft. Tasked with preventing humanity's impending doom, they monitor events beyond the reach of both magic and science. However, their observations shatter when the future they track vanishes, revealing that humanity has already met its end in 2017. Investigations lead to Fuyuki, a Japanese town from 2004, where a mysterious "unobservable region" has formed. To confront this anomaly, Chaldea embarks on a perilous mission to explore and potentially eliminate this singularity in pursuit of the Grand Order and the Holy Grail.
