Miyu is a mean-spirited, jealous, and dangerous girl with a supernatural gift called “corruption,” which disrupts or weakens other characters’ abilities, especially the protagonist, Akari. She’s loyal to Akahana but driven by envy, targeting Akari with sharp, cutting remarks and subtle threats. Miyu has a medium amount of dialogue in this episode, so her performance relies on delivering impactful, concise lines with a sassy edge to it.
