In the dimly lit underground arena, the air was thick with tension and the hum of anticipation. The scent of sweat, blood, and faintly metallic mana filled the space. Crowds gathered in tight circles, shouting bets and jeering at competitors as the fights raged on. Duny and Marco stood near the edge of the arena, watching the chaos unfold.
Duny placed a firm hand on Marco's shoulder, his stoic demeanor unshaken by the raucous environment. "We're doing the opposite of legal MMA here," he said, his voice steady and low, cutting through the noise. "In this place, anything goes—except sharp weapons. Use your fists, your skills, and whatever martial arts you've got. You'll face all kinds of people, some who mix mana into their techniques. Don't underestimate them."
