Two streaks of light flashed in the underground sewers.
The demon agent's hands twisted and turned into large claws stretching for meters as he swung his hand at Eugene.
Unfazed, Eugene countered with his blade. The sharp sword-like claws smacked against the purple-yellow sword of the young man, sparks flying with each of their movements.
Eugene took a step back and winded up for a giant swing. The agent jumped to his back and covered his chest with his claws. Just as he thought he was out of range, Eugene's aura took form and dug deep into the nails of the agent.
"Kahk!" The agent screamed in pain. "Aura Ki!? Weren't you a fucking magician?!"
Eugene brandished his blade and smirked, his eyes like icicles. "I still am."
The demon's agent couldn't make sense of it at first, but then the realization dawned on him. "D-dual... core—"
Eugene didn't let him finish his sentence. In the next moment, hundreds of fireballs went darting toward the agent.
