i've just started grinding 6-4 for nihongou and every time i get a B rank (bc of that damn enemy yari at the bottom and even when my swords double awaken they hit other enemies ;_;) i know usually B ranks still give a chance for a drop but so far no drops?? is 6-4 special and need A rank for a drop?
