Like a Dragon: Ishin! is a period piece featuring a ton of different characters from all over the Like a Dragon series hailing from what I consider to be the golden age of the series (between 5 and 0). It's really good! I didn't know dick all about the history of this time period, and it was interesting to see it adapted in the typical LAD style, with all the reveals, betrayals, and sworn-brothering that entails. The setting really fits LAD like a glove, and I'd love to see more period pieces like these with this cast.
