How about a personalized manga comic book? You can hire an artist to create a manga-style comic book that features illustrations of you and your girlfriend, with a storyline that reflects your relationship, shared interests, and adventures together. This would be a unique and meaningful gift that shows you've put thought and effort into it. Alternatively, you could get her a manga subscription box that sends her new, popular releases each month. Or, you could get her a set of beautiful manga art prints, so she can decorate her space with her favorite characters and scenes.
Or you can get her a star map with the date of your anniversary.
