What Demon Slayer: Kimetsu no Yaiba - Sibling's Bond is
Moonless night. A bloodied cleaver glints on the kitchen floor. A boy carries his charcoal sack past corpse-strewn tatami, stops when small hands clench his sleeve. She hisses at moonlight yet shares his tears. Evening light slants across a demon-hunter train platform, the sister tucked in a wooden crate, pounding from within.
