A sage named Uryssia, who had called forth the students, asks them to save the world, but when they resist, Uryssia kills several students as a warning. The students are filled with fear, but one male student defies Uryssia, and Uryssia casts magic at him. However, even after being hit by the magic, the male student stands there as if nothing had happened. Bewildered by this impossible sight, Uryssia uses appraisal magic to examine the male student's skills. "Skill 'Gag Manga'?"
