(Also, Joe has an adorable curly fro in this one XD! Reminds me of Spike and Mugen).
But please, if you haven't watched the original Ashita no Joe first please watch that trail-blazing classic! I clicked on it out of boredom and ended up getting sucked in and I normally am very picky with sports anime. Joe had some serious feels and some high caliber, nuanced writing. It was like Catcher in the Rye meets boxing :XD: This show also dared to cover the harsher side of boxing reality like career-ending injuries, brain damage, losing friends and rivals to the very sport you love. 10/10 for me!
Peace and God bless!
