Dragon's carrying her staff sword. Is she gonna dual wield staff and sword? On that note, wouldn't it be possible for a mage to carry around like 10 staffs engraved with different magic circles in them so that they wouldn't have to spend time drawing out their circles.
@Crookshanks I can't remember if they do mention this in the manga, but in the light novel they do say that since it is an event for first years, he was prohibited of using advanced magic.
