The ninjas do use magic. Throwing weapons and swords on the other hand.... no. Not unless the final character is pulling a Genra and breaking all the damn rules.
I mean, it is entirely plausible the final character IS the Genra replacement much as Nyo-Tengu was Bankotsubos replacement. They can't really bring Genra back through normal means. He was cremated. That makes him pretty definitively dead.
