The information provided by Emerald Sparrow did indeed have an effect on the second day of the written exam.
During the first exam on the second day, which was the "Residual Beast Analysis" exam, under the deliberate investigation by the invigilators, a portion of problematic magical girls were quickly identified.
During the exam, dozens of magical girls were caught using malicious magic techniques. Although this number is not significant among thousands of examinees, it is still a number not to be underestimated.
These magical girls indeed used a technique called "Chaos Technique" during the assessment, which can slightly affect others' memory and decision-making without being noticed. Due to its weak effect and inability to be enhanced by higher magic power output, it has low practical value in combat. Moreover, it has a high practice cost, making it an unpopular technique among unpopular techniques, and typically, no magical girl would bother practicing it.
