Houkago no Mahou Sensou

In the shadows of the world, “Mages” operate in secret. They wage daily battles over “Magic Quartz,” the source of their magical powers, and now, wagering the workshops that produce the highest-quality quartz, they have begun a “Magic War (Black Arts)” at a certain academy. Sankurou, a boy born to a mage father but lacking any magical talent dislikes the world of mages. However, he somehow finds himself caught up in this war alongside his childhood friend Neneko. Former friends and teachers revealing their true natures become enemies, and he must struggle to survive. Can he protect Neneko, an ordinary girl unaware of the magical conflict? A school-based magical battle royale filled with ambition and conspiracy is about to begin! (Source: Kadokawa translated)
