On that note, I’d also recommend Urban Martial Arts System. I hesitated a bit since it’s set in a modern world, but it is Academy themed and also has some face slapping. The good thing I like about the face slapping here is that not everybody just want to die. There are those who know of his name and no longer bother provoking him. The first few chapters are wonky, though. Brave yourself during the first parts, and you’ll get to the good chunks of meat.
