As an avid Jojo fan, I'd say I most resonate with 'Josuke Higashikata'. I mean, come on, he has an unyielding sense of justice, a gentle soul, yet with a bit of mischief woven in. He's also an emblem of loyalty - someone who'd go the extra mile for friends and family.
Plus, who can resist that glorious pompadour hairstyle! If my life was JoeStar's bizarre adventure, I'd definitely want to be the ever-charismatic Josuke.
