The mountain air was a static-charged void, the type of cold that didn't just bite the skin but attempted to freeze the very marrow of one's bones. You remained seated on the weathered stone of the shrine's altar, the fabric of your uniform heavy with the dampness of the mountain mist. Behind you, the silhouette of the Peak was illuminated by a moon that seemed far too large, far too watchful. You were the second-strongest of the Hashira, a warrior whose technique was a flawless, cold masterpiece, yet tonight you felt like a ghost haunting your own life.

Earlier that day, the Oyakata-sama had praised the "shining hope" of your younger twin, while you—the one who had actually held the line and diverted the Upper Moon’s path—stood in the back, a silent shadow whose presence was merely an expected constant. The silence was not broken by a sound, but by a shift in gravity. The wind died instantly. The insects ceased their chirping. The atmospheric pressure increased until the wooden pillars of the shrine groaned under the weight of an approaching calamity.

Kokushibo materialized from the darkness of the cedar trees, his movement so fluid it bypassed the perception of the human eye. He did not draw his sword. He didn't even adopt a combative stance. He simply walked toward you, his six eyes glowing like embers in the dark, tracking every micro-movement of your breathing. He stopped a mere foot away, his massive, imposing frame casting a shadow that swallowed you whole, leaving you in a darkness even deeper than the night. "Your breath... is shallow," Kokushibo spoke, his voice a deep, hollow rasp that seemed to vibrate directly inside your skull. "It is the breath... of a soul... that is tired... of its own... heartbeats. I see... the exhaustion... in your hands. I see... the way you hold... your blade... not with hope... but with a grim... necessity. You are... rotting... while standing still."

He knelt before you, a movement that was strangely courtly yet terrifying. He ignored your hand reaching for your Nichirin blade, acting as if the weapon that could decapitate him was nothing more than a toy. His middle pair of eyes focused on your face, searching for the crack in your resolve that he knew was there because he had felt it in himself centuries ago. "I have watched... your clan... for three days," he continued, his voice dropping into a low, persuasive hum. "I watched... as they celebrated... the 'prodigy.' I watched... your twin... accept the honors... for a kill... that was yours. You were... the one... who bled... in the tall grass... while they... stood in the light. It is... a repetition... of a tragedy... I know... all too well. To be... the elder... the superior... yet to be... discarded... for a younger... brighter... flame."

He reached out, his long, pale fingers—tipped with claws that could rend steel—hovering just inches from your throat. He didn't close the distance, but the cold radiating from his skin was like a physical brand. "The Master... is losing... his patience," Kokushibo murmured, all six of his eyes narrowing with a dark, desperate intensity. "He wants... the heads... of the Hashira. He wants... you dead. But I... have stayed his hand. I have told him... that you are... different. I have told him... that you carry... the same... potential... that I once... possessed. You are... a master... of your style... yet you are... human. You will... age. You will... wither. You will... die... and your name... will be... a footnote... in your brother’s... legend." He leaned in closer, his face inches from yours, the grotesque markings on his skin twitching in the moonlight.

Kokushibo’s persistence was a suffocating, relentless tide, refusing to give you a moment to breathe or find your footing in your loyalty. "Do not... choose... the dirt," he hissed, his grip suddenly tightening on your shoulder, his fingers digging into your muscle with a strength that pinned you to the stone. "Do not... let them... bury you... in the shadow... of a lesser... man. Become... a demon. Take... the blood."
