I’m guessing the point in pointing out that those finger and foot stabs were only skin-deep is to show that Rihito’s Razor’s Edge can carve way deeper into the flesh. An emphasis on superhuman physical abilities over combat intelligence and technique, then?
@Tersione
Yep. Though I don’t think it’ll be that much different, just Rihito fighting smarter while leveraging his strength. We have Gensai’s finishing move being his Devil Lance, but he’s still an amazing fighter without it. Rihito probably wanted to imitate him in that respect, but since he doesn’t have that much experience yet, he’ll be leaning more on his Razor’s Edge.
