In a world where magic and superpowers coexist, a secret buried within the greatest academy awakens.
Hundreds of years ago, "Abilities"—powers that transcend human common sense—were discovered across the globe. From those who manipulate fire and freeze time to those who speak with beasts or foresee the future. People began calling them Ability Users, and as their numbers grew, nations established institutions to systematically educate and manage these powers. Among them, the most renowned is Arcadia Academy. It is a legendary school and a top-tier educational institution where Ability Users from all over the world gather, producing outstanding talents for generations. However, Arcadia hides another face, one never revealed to its students. Deep beneath the academy grounds lies "Sector 0," a place that does not exist in official records. And there, something related to an incident erased from the academy's history remains sealed.
