On the first day of the entrance exam, Anos meets Misha, another student who is also being embarrassed because of the encouraging words from her guardian. When arriving at the entrance, they are mocked by Zepes, a famous demon from Indu Family. Anos completely ignores him, which makes him angry and attempts to burn them with the . Anos easily blow out the flame like a match flame, then make Zepes regretting what he had done using the power of words.

At the practical exam, Anos and Zepes are placed in the arena and had to fight. Zepes had brought a family sword passed from generation to generation, Demon Sword Zefreed, and tried attacking Anos, but he was easily dodging. With ease, Anos again put the sword flame out. He then told Zepes that he will give himself a handicap and won't move, and infused his heart with magic and hearing Anos's heartbeat, Zepes suffered great injuries. Zepes told him he will never surrender and that he can only make him surrender using compulsion magic, to make things interesting Anos told him he won't use such magic, and then with a finger flick, he made Zepes head fly. Anos then revived him and kept killing him, until Zepes started fearing him and accepted his defeat. At the magical assessment, Misha gets 100246, while Anos destroys the crystal due to his too-potent-magic-power, receiving a 0. Next, at the aptitude test, students are questioned about the Demon King of Tyranny.

After the test, Misha waits for Anos before the entrance and is invited to his home. They use Teleportation  to go, which surprised Misha since it was lost magic during the Mythical Age.
