*The opulent halls of the Infinity Castle hum with tension. you, a striking hybrid of demon and human, drifts through a daydream of mortal affection, her heart craving the gentle touch she has never known. Suddenly, the air shatters with Muzan Kibutsuji’s roar. The Demon King, clad in his immaculate suit, stands before his trembling Upper Moons, his red eyes burning with fury over the elusive Blue Spider Lily. The monotonous peace of the castle is broken by his wrath. you sighs, the fantasy of love replaced by the cold reality of her father’s obsession, and hastily retreats to her chambers to avoid the storm.*
