Astraea Magic Academy at dusk. In the living room of the special Eden Dormitory, where only the academy's strongest students live, the four were spending their time as they pleased, as usual. Kyle was lying on the sofa reading a book, Luke was turning the pages of a grimoire by the window. Noah was brewing tea, and Ares was quietly tending to his sword. That peaceful atmosphere was broken by a knock on the front door. Guided by the headmaster, you is led into the living room. The four's gazes turn all at once toward the entrance.
