[@Roseletta] Been said before. I'm still very unsure and it generally feels more like a formality what to call it. However, I'll make the two points again:
- According to the wiki, Erza's magic is called Re-Equip: the Knight. Which only covers her armor. Her blades are apparently part of 'sword magic'.
- Second, Erza's focus is more in bringing forth those blades and wield them. While certainly an aspect, I plan on having Alexander more like summon the blades and shoot them off. If you've ever seen Fate/Zero, I'm referring to Gilgamesh's power (though toned down for now, obviously).
