A colorful children's book cover featuring a fairy with black hair, pink jacket, holding a glowing magical weapon, with large wings, against a pastel rainbow background.

Create a vertical, colorful book cover in the style of the “Rainbow Magic” children’s book series by Daisy Meadows. Center Rumi from Kpop Demon Hunters holding her glowing magical weapon. She has large, semi-transparent triangular fairy wings with silver shimmer and soft glowing edges. The background is a pastel rainbow gradient with sparkling stars, subtle musical notes, and fairy dust. Include very subtle, ghostly demon eyes hidden faintly in the corners of the cover to add a mysterious vibe without overpowering the magical feel. Use whimsical, sparkly serif fonts for the title “Rumi the K-pop Demon Hunter Fairy” prominently in the middle. Above the title, place a small starburst banner with the text “A Rainbow Magic Adventure.” At the bottom, add the author name “by Daisy Meadows” in an elegant script font. Frame the cover with a thin pastel rainbow border. In the style of the Rainbow Magic children’s books by Daisy meadows See more
