A movie? Well, *guess* that it's better that way. Less room(?) for mucked-up characters... or the fixing of said-of traits. I'm still looking forward to the fight scenes. Badass girls in knife fights are always a treat to watch, given the right production studio.
That reminds me. Is Ryogi (and I guess all Shiki personas in the Nasuverse) an expert in all sorts of melee weaponry? Or do they just prefer knives and katanas?
