Are there any settings/gimmicks battle shounens could use to be original? We already have ninjas (Naruto), pirates (One piece), martial arts (dragon ball and couple others), superheroes (MHA) etc. Heck, we even have at least two wizard ones (FT and Black Clover)! Are there any settings/gimmicks left? Or do new battle shounens have to use something that has already been done? If yes, any ideas how they can make it unique from others?
