The Misfit of Demon King Academy (2020) : 1x5

Shortly after Anos’ encounter with Misha and Sasha as well as his battle with Ivis, a transfer student named Ray enters the Demon Academy. As the Master of Magic Sword and powerful enough to defeat the Seven Elder Demon Emperors, Ray makes it clear that he wants to join a team with a capable leader, and requests to join Anos’ team. However, Anos refuses and proposes to Ray that, "If you prove that you are worthy, I will allow you to become one of my followers." Ray decides to form his own team and battles head-to-head with Team Anos during the team competition exam.
