Before watching this series, I only knew Hokuto no Ken (HNK) because of the iconic "you're already dead" scene as well as it inspiring some aspects of the Yakuza series. I started watching this series on a random whim and I am thankful for doing so.
HNK felt like the anime equivalent of Yakuza: A series with a strong story and entertaining fights while still having comedy sprinkled throughout. It does a great job of starting off as a goofy, over-the-top action show and slowly transitions to a more plot heavy one that still recognizes to not take itself too seriously. That being said, there are some amazing twists and moments in the series that hit me hard in the feels.
In conclusion: I は SHOCK at how great this series is. Hands down my favorite!
