How about getting her a subscription to a monthly manga magazine? You could also get her some manga-themed merchandise such as a t-shirt, pillow or bag with her favorite character on it. Another idea would be to get her a set of manga books personalized with her name or a message, so she can display them on her bookshelf. Additionally, you could purchase her a gift card to visit her nearest manga store to choose her own favourite mangas to read.
Or you can get her a star map with the date when she was born.
