Kamisama Hajimemashita was the first anime I watched, besides Studio Ghibli movies, and the first manga I read. What stands out in my mind in terms of her style is her nice use of screentones and her many beautiful floral scenes.
Something else I enjoy about this manga is the storytelling and characters. Nanami is a strong character who follows her own feelings and doesn't let herself be influenced by others, meeting the unusual events she faces head on, but she is still just a teenager who faces the same challenges and problems as regular teenagers.
