Fate/Grand Order: First Order
What they share
Both films are directed by Hitoshi Nanba, and they sit in Action / Animation / Fantasy territory. If that's the register that drew you to Fate/Grand Order: Moonlight/Lostroom, the second film will land in a comparable space — through a different lens.
What Fate/Grand Order: First Order is
You're a magecraft preservationist monitoring 2015, the last year magic still flourished. One day the future vanishes and humanity is already dead. A singularity in 2004 Fuyuki is the rupture point so Chaldea dispatches a team to close the wound before it spreads. The camera lingers on the moment a servant first answers the call.
