Anos and the students from the Demon King Academy participate in their first day of inter-academy exchange with the Hero Academy. However, the students from the Demon King Academy soon find out that the inter-academy exchange is in name only, and they are met with outright hostility. Revest, a third-year student at the top of his class from the Demon King Academy is ridiculed by the students from the Hero Academy when he unsuccessfully tries to activate a magic spell. The students from the Demon King Academy are visibly offended by this treatment, but Anos’ words turn the tables. "As usual, humans sure like to set traps for us, don’t they?" The inter-academy exchange is off to an ominous start.

Round 2 of the inter-academy exams begins. After Revest’s deplorable defeat against Heine, Anos and his team battle with the students of the Hero Academy. Anos says that he will think of a strategy if it becomes necessary, and clashes head-on with his enemies using his vast Magic Powers. However, due to a magic barrier called De Igelia that is cast over the entire city, and a young girl named Zeshia who wields the holy sword Enhale, Anos’ attacks prove to be futile. Anos and his team are unable to come up with their next strategy, but Misha proposes a plan that could help them win.

Anos and his classmates search around Demon King Academy for the “Child of God.” While Anos’ comrades are fending off the attacks from the demons of two thousand years ago, Anos himself faces the King of Death’s Army Officer, Ziek Ozma, in a duel of intellect. In this duel, Anos must speculate who the “Child of God” is and make the correct guess. However, the number of times he can make his guess is limited.

What was Anos’ answer, and what is Ziek’s motive ― ?!
