Oh, the Yakuza series is such a wild ride! If you're talking about the manga adaptations of the 'Like a Dragon' games (formerly known as 'Yakuza' in the West), there's actually a mix of official and unofficial translations floating around. The main series, like 'Yakuza: The Comic', did get some official English releases, but they're pretty niche and harder to find compared to the games. I stumbled upon a few volumes at a local comic shop years ago, and the art style totally captures the gritty, over-the-top vibe of the games.
For spin-offs or side stories, you might have to dig into fan translations online—some scanlation groups have tackled lesser-known titles. It's a shame more of it isn't officially available, because the manga dives deeper into side characters like Majima, who’s honestly the best part of the franchise. If you’re into crime dramas with a dose of absurd humor, it’s worth hunting down, even if you have to piece together bits from different sources.
