The colossal beast charged with earth-shaking force. Ken dodged just in time as its metal claws gouged deep into the cracked ground.
His body felt heavier, the Abyss Form threatening to overwhelm him with raw power. But Ken forced himself to focus, channeling the dark aura into precise strikes.
He landed a blow to the beast's side, but the creature barely flinched, its eyes burning with rage.
"You're stronger than I expected," the shadow figure from before murmured, watching silently.
Ken gritted his teeth. "I don't care how strong you are. I'm not losing to some monster."
The fight raged on, with Ken narrowly avoiding death multiple times. Each strike pushed his limits, but he learned to weave his power — using Abyss energy not as a reckless force, but as a weapon of control.
Finally, with a desperate surge, Ken plunged his glowing fists into the beast's core. The monster let out a deafening roar before collapsing in a pile of broken metal and flesh.
Ken staggered back, panting heavily. His eyes flickered between his natural self and the glowing Abyss Form.
"This power... it's mine to control," he said quietly.
