I understand what you mean, but ,unlike kung fu, there is only one style of ninjutsu. However, ninjutsu IS made up of several facets. The facet Daredevil is supposedly using is taijutsu. Taijutsu is essentially the striking aspect of ninjutsu. I have seen taijutsu guys fight and I have a couple of friends who train in taijutsu, as well as some other parts of ninjutsu. The techniques Daredevil employ bear little to no resemblance to any techniques I have seen. I honestly think the writers are just throwing in strikes that look cool and "ninja-ey" and really have no idea about the style itself.
It's possible that the writers did some research and found some rare techniques to draw, but I highly doubt that.
