Summary
Diego Ijeiska served as the headmaster of the Hero Academy and instructed the elite Jerga-Kanon class. Like many of his high-ranking students, he harbored a deep arrogance toward the Demon King Academy and its pupils. His belief in human superiority was evident in how he frequently belittled Delsgade's students, even resorting to cheating during magic demonstrations and examinations to deliberately humiliate them.
