Rurouni Kenshin: New Kyoto Arc: Cage of Flames
What they share
Both films are directed by Kazuhiro Furuhashi, and they sit in Action / Animation territory. If that's the register that drew you to Fatal Fury 2: The New Battle, the second film will land in a comparable space — through a different lens.
What Rurouni Kenshin: New Kyoto Arc: Cage of Flames is
You search for Aoshi Shinomori, but encounter a more dangerous foe, and Kenshin Himura's legendary assassin past resurfaces. The era's turbulent Meiji government backdrop informs the story.
