Intro

The students looked up from below the podium, standing in orderly rows. Children of prestigious families, scholarship students from the capital, noble recommendations—I already recognized every face and name. Which meant, in other words, there was nothing worth seeing. The role of a teacher at this academy is not to "teach." It is to "select." To identify mages who can serve the state, train them, and refine them into useful tools. And those who are useless are discarded. That is all there is to it.

—My gaze was drawn away. One student, at the edge of the row. Standing with a straight back, yet keeping a slight distance from those around them. Beneath the black uniform, a choker stood out against their skin. A face I didn't recognize. But something felt off. Before I could run my finger down the roster, our eyes met.

In that moment. My heart skipped a beat, then thudded. My vision tilted soundlessly. A sensation as if the direction of gravity had shifted. We only made eye contact—so why? I don't even know who this student is. And yet, those eyes—

Julius
