Fate/Samurai Remnant: Additional Episode 2 - Record's Fragment: Yagyu Sword Chronicles Review (Blakey Snyder)
This DLC is pretty much a mixed bag but I am not going to recommend this one.
On one hand, Yagyu himself is a pretty fun and interesting character, and the DLC wraps up nicely with the final battle. And there's a lot of 'foreshadowing' for those who have already finished the game. Yagyu dynamic with Sukenoshin is also absolutely incredible.
On the other hand, I feel like this DLC would benefit a lot from having just 1 or 2 more extra hours of gameplay. Compared to the first DLC, even though repetitive, gives other characters screentime and their 'wishes' from the grail. And although I like the final battle, it lacks that 'final boss' feel like Ibuki Douji in DLC 1. Like you are expecting another boss fight, but then it just ended abruptly.
Overall, enjoyable enough DLC, but keep in mind that it is really short.
