Shall we go in this direction then: Nanami, using a mundane curved sword and dagger has taken out a few mutated thingamajigs but the storm is getting worse making visibility lower. She's currently getting overpowered by these things and possibly yelling not so much obscenities but angry words not quite befitting of a lady of her status. Some of her foes may be part of a hallucination due to prolonged exposure to the madness wave and probably her straying a little ways up the slopes.

LOL just don't call her a kid to her face. XD
