As the year nears its end, the time for final exams arrives at Rigarden Magical Academy. Despite being the only student without any magic aptitude, Will Serfort aims to score perfect grades in every subject, which would allow him to ascend to the Wizard's Tower and reunite with his childhood friend, Elfaria Albis Serfort. However, Will's hard work comes tumbling down when he fails the very last, biased exam, disqualifying him from entering the Wizard's Tower. Meanwhile, Elfaria and the other Magia Vander—the five most powerful mages—perform the annual ritual that protects their world from the dangerous Celestial Hosts. As the ritual temporarily leaves the Magia Vander drained of magic, a large army of monsters suddenly appears and begins attacking mages and civilians alike. To make matters worse, the mages are unable to hold off the invasion due to the monsters' special weaponry that nullifies their magic. Refusing to let the world end in despair, Will and his masterful swordsmanship quickly become a cornerstone in stopping the attack. [Written by MAL Rewrite]
