Casper gazed at Ken and then condescendingly blinked his eyes. "Do you really intend to challenge me, insignificant human?" he sneered.
Ken nodded firmly, resolute in his determination.
"Ah, the naivete of youth," Casper sighed, shaking his head. "These days, young people read too many fairy tales and believe they can become Dragon Slayers." He paused for a moment, his face contorting with the recollection of a bitter memory. "Let me show you what a real dragon is capable of," he growled.
Casper's playful smirk vanished as he concentrated, gathering energy in the tip of his finger.
[Void Sphere]
The air around him grew heavy with anticipation, crackling with dark energy.
Suddenly, a sphere of darkness materialized at the tip of his finger, pulsating with power.
Without hesitation, Casper hurled it toward Ken, who barely had time to react.
