Kairen's eyes glowed an intense green as he invoked 'Tempest Fury.' The air around him spun violently, forming a vortex of energy that crackled with destructive power. He had always been reluctant to use this ability, knowing its unpredictable nature and the immense toll it took on him. But now, with no other option, he had to unleash it against the towering monster.
The tall monster's body began to glow with a sinister red aura, its eyes narrowing as it sensed the approaching threat. With a roar, it met Kairen's attack head-on, the two forces colliding in a cataclysmic clash.
The cave shook with the impact, the walls vibrating as the energy from their clash sent shockwaves through the air. The silhouettes of Kairen and the monster were visible in the blinding light, their forms locked in a fierce struggle. From an outsider's perspective, it looked as if two monsters engaged in a fierce fight - a green and red monster.
