Rokushiki has always been a clean fighting style to me (Soru and classic Rankyaku being reproposed again), the way Who's Who is showing adaptations combined with his DF (sending a jaws-shaped Rankyaku from his mouth, showing a variant from Shigan, which is "Hagan" and requires a sharp weapon like a dagger) is something I like a lot.
I was already hyped with this battle, not it has my full attention.
