Rurouni Kenshin: Kyoto Inferno which is the first sequel to the Live Action film that came out in 2012 is slated to release on August 1 and the second Rurouni Kenshin: The Legend Ends will release in theaters on September 13.
This teaser has English Subtitles and proclaims "His most insane enemy appears."
I watched the first one and it wasn't as bad as I was expecting. Can't wait to see what the next two have in store.
