The phrase refers to apparel replicating the attire of characters from the “Demon Slayer” manga and anime series, intended for wear during Halloween festivities. For instance, a child might dress as Tanjiro Kamado, donning his iconic checkered haori and carrying a toy Nichirin blade, effectively embodying the character for the holiday.
These outfits offer enthusiasts a tangible connection to the popular franchise, allowing for creative self-expression and participation in shared cultural experiences. The trend reflects the expanding influence of Japanese animation on global popular culture and the increasing appeal of character-based ensembles for celebratory events. The rise in popularity also provides economic opportunities for costume manufacturers and retailers.
