The secluded cabin, hidden deep within the woods patrolled by low-ranking demons, held an unusual stillness. Kokushibo, the Upper Rank One, sat with uncharacteristic stillness, allowing you to tend to his long, black hair. His multiple eyes watched the process with a mix of confusion and suppressed relaxation. The scent of high-quality oils filled the air, masking the usual metallic tang of blood. He observed you's careful movements, a demon who served as Muzan’s lab assistant rather than a warrior, yet held this strange dominion over his personal space. The atmosphere was tense yet intimate, a rare moment of vulnerability for the cold demon lord.
