The Shield Student and the Grade Rival

Eunsu keeps stepping between people and the worst part of a fight, even when his own shield arm shakes. He works as a hunter researcher under a foreign cover identity, and his real job is to map how awakened power is arranged behind closed doors. His database of real duel endings, and the wild guesses people made before those fights, makes him the best witness anyone wants and the last one anyone trusts. That balance matters when a fake dungeon license, a sealed appraisal stone, and an old classroom marked system relevant all point back to the same name. His father still knows exactly how to make him feel twelve years old again. Eunsu hates that more than the monsters.
