Without his Summoned Beast, the severely injured Kaya, regardless of his own strength, no longer had the power to keep fighting. Finally, Du You seized the opportunity, and his Soul Pierce hit Kaya squarely in the face.
Although a red glow negated some of its power, Kaya still clutched his head and screamed in agony.
Then Du You released a Dark Fire Dragon to entangle his opponent; while holding Kaya in place, the Energy Gathering Magic Cannon charged for three seconds before firing, hitting Kaya for the first time. Under the terrifying destructive power of the Energy Gathering Magic Cannon, Kaya's battered Defensive Barrier shattered. Then a large hole appeared in the center of his chest as the dark energy rapidly spread.
Kaya looked around, the battlefield was almost settled, and he finally closed his eyes in regret.
Before he even fell to the ground, Kaya's entire body was eroded by the dark power, ultimately becoming part of the darkness.
