Satsuki Kurahashi lives next door to the main protagonist, Fushihara. She is a home-based illustrator who, like Fushihara, possesses the ability to perceive non-human entities. Kurahashi-san displays a lazy disposition and frequently whines, behaviors which consistently annoy her companion, Lily. This interaction forms a core aspect of her character portrayal. Her role remains supportive throughout the series' episodes, manga volumes, and related media, defined by her illustration work, her spiritual perception, and her established dynamic with Lily.
