The air between Kaito and Grigori was thick with an unnatural silence. They stood facing each other on a once-green field, but in Kaito's presence, the verdant life had been consumed. The grass, the sparse wildflowers, even the topsoil had turned to a fine, gray ash.
Grigori looked around at the desolate scenery, a smirk playing on his lips. "An interesting ability. You're absorbing all life force around you. However, it's useless against me."
Kaito said nothing. He simply rushed forward, his ashen hair whipping behind him, and threw a punch with a force that warped the air. Grigori, with an almost bored expression, easily caught the blow in his palm. But the moment his hand made contact, the smirk vanished. His eyes widened in shock, and he instantly backed off, a look of profound unease on his face.
Grigori looked down at his hand. A dark, spiderweb-like network of wrinkles was spreading from his palm up his arm. "What is this? How could a mere curse affect me?"
Kaito pressed the advantage, following up with another punch. Grigori evaded it this time, but the curse continued to spread. With a look of cold, calculating fury, Grigori ripped his own arm off at the shoulder, letting the blackening limb fall to the ground where it instantly crumbled to ash. A new arm regrew in its place. "So that's how it is. Your curse inherited its 'indestructible' nature. That very nature had defeated me before. No spell of mine would damage you, thus, I shall seal you away!"
The air grew heavy with ancient power. Grigori, channeling both his own will and the might of the No Life King behind him, began to chant.
"Sepultura Viventium!"
"Vinculum Vitae Inane!"
"Cavea Spiritus!"
"Ritus Supressio!"
"Anima Clausura!"
"Silentium Ultima!"
Layer upon layer of restriction was placed upon Kaito. Chains of pure force and ethereal energy wrapped around him, both physically and metaphysically. His body seemed to warp from reality as his form began to dissolve into the void.
"I don't know what you were expecting," Grigori sneered, a triumphant look in his eyes. "As someone who has been sealed himself, I would know how to deal with an 'unkillable' opponent like yourself. I expected more, but you'll die like the rest."
But then, Grigori's newly grown arm began to blacken, the curse continuing its relentless spread again. He held his arm up and watched in disbelief as it started to crumble to ash. The curse rapidly spread, enveloping his entire body and a shocked, silent gasp escaping his lips as his form dissolved into ash.
The No Life King's skeletal form stood alone, its soul flame flickering with a whole consciousness. It watched as the intricate bindings it had placed on Kaito began to violently shake. One by one, it snapped with a deafening crack. Kaito's form returned to reality. He moved through the last of his restrictions as if they were nothing more than a gentle breeze.
Kaito delivered a hard, crushing punch to the No Life King's skeletal face. The force of the blow was immense, sending the figure flying backward. Kaito followed instantly, stomping on the No Life King's face and digging its head into the ground. Stomp after stomp impacted all over the ancient bones, each blow echoing like a thunderclap, carving a large crater into the earth.
The No Life King's bones started to shatter under the onslaught, but just like the lesser undead, an unknown force quickly mended them. Despite this, Kaito continued his relentless assault of pure physical force, devoid of any thread of holy power. He had no intention of letting the No Life King rest.
The No Life King, under the barrage of attacks, spoke with a low, grating sound as its soul flame flickered wildly. "I'm immortal, nothing you can do can kill me. Now fall into an eternal rest."
The King began to cast a spell of his namesake.
"Requiem Cretae!"
A haunting yet beautiful song ran out in Kaito's mind and the surrounding.
Kaito suddenly stopped moving.
