The characters have physical weapons like Sailor Venus has a sword, a chain and a boomerang, Sailor Saturn has a glaive, Sailor Uranus has a sword, Sailor Moon has her tiara she uses as a boomerang, Tuxedo Mask has a cane and throwing roses. I'm not sure if I missed anything.
I think technically Moon has a sword too.
I happen to be studying the First World War a lot and medieval type weapons often made comebacks in surprising ways in the narrowness and close quarters of the trenches, like knives combined with brass knuckles, flairs and maces, taking the bayonet off their rifles and using them like short swords, and so I am familiar with a number of weapons like this.
Still, I would have emphasized their role more like the gods of Rome, they are weapons in their own right. A few gigajoules of lightning through you would certainly not make your day if Jupiter was anywhere near you.
