A brush in hand, elastics up her wrist, the mom works tirelessly to create a braid on her daughter that emulates the strength and power of a demon slayer.She's only mortal, but she knows the pressure is on: She's trying to sculpt her little one's hair to look like the KPop Demon Hunters heroine whose long, voluminous lavender braid is the style of the summer. Mom does her best. Rumi's animated after all.
