Is there any anime focused on martial arts at all? As in, real martial arts, not stuff like Naruto nor Dragon Ball Z.
Something like Avatar: The Last Airbender or The Legend of Korra would be freaking awesome, in my opinion. I really like the symbolism and martial art themes in those series.
Fist of the blue sky
Aiki (a bit of not real martial arts probably thrown in there)
the breaker season 1
also how is avatar real martial arts..?
