The Fruzen Blade is a very large sword that is often used by Giants, but for some reason it disappeared from world civilization, and the sword is believed to be the strongest sword, due to its rare manufacturing materials, which could only be taken by Giants who had long been extinct due to past great battles, in the past the Giants were feared by all humans, because their powerful strength could destroy a Kingdom with just one strike, i that's why the Giants are so feared by humans.
