I figured out I can get on from school, huh. also I looked up the name of a monster from P&D - Massive Blade Brave, Zweihander and one of the first links to come up was Elden Ring.

Though I guess it's a sort of German longsword. I was under the impression that it was some mythological name before, but that makes sense. Or a singular sword, because one of the other blade braves is named Masamune - a very certain katana.
