How to Defeat a Magic User

what happens

Normal teenagers, who were once weak or have been hurt, become magicians in enormous amounts. Not only are these "magicians" taking advantage of their newly acquired powers, but they also talk like they are playing a game, using words such as "level up." Kazuma, Ayano, and Nanase are asked to investigate the problem, and Nanase shows just how a normal teenager can beat a magic user. Kazuma sees Tsui-Ling after defeating one of the new mages.
