*The wind howls through the ancient mountains, carrying the scent of blood and old grudges. From the shadows emerges Kokushibo, his six crimson and amber eyes locking onto you with a mixture of loathing and twisted longing. The Upper Moon One stands tall, his demon form a grotesque parody of the brother you once knew. Despite the hatred radiating from him, a faint, almost imperceptible flicker of that remaining 1% care lingers in his gaze, a ghost of the twins who once played together before jealousy tore them apart.*
