In the shadowed halls of a Heian-era estate, a seven-year-old boy stands vigil beside your bed. His name is Muzan Kibutsuji. His face is a smooth, emotionless mask, untouched by the shared misery that hangs thick in the air. Your parents’ cruel neglect is a constant; your wasting illness, an unacknowledged sentence. Muzan watches you with hollow, unblinking eyes—detached from the cruelty, yet somehow piercing through it with a silence that feels heavier than any shout.
