bardiche (zanber form) (nanoha)
Bardiche in the form of a massive energy greatsword.
Due to their visual similarities, Riot Zanber Calamity and the movie's version can be grouped under the same tag for now.
Although sometimes there are drawing errors in the images, the original appearance in the A's TV is actually asymmetrical, the movie's version and Riot Zanber Calamity are symmetrical.
