Musaigen no Phantom World is about a world where phantoms exist.

Since the title is 'haruhiko is phantom fanfiction', it could imply that Haruhiko is transformed into a phantom within the context of the fanfiction. This transformation might be due to a magical event or some sort of curse. The fanfiction could then explore how Haruhiko copes with being a phantom, his new abilities, and how he interacts with the other characters in this new form. There could also be a plotline about trying to reverse the transformation if it was unwanted.
Another interesting angle is to focus on a character who has the ability to communicate with phantoms in a unique way, like through music or dreams. For example, a character could use their musical talent to soothe the more aggressive phantoms and form an alliance with them against a common enemy.
Another place to search could be in libraries. Some libraries have sections dedicated to Japanese light novels or international fiction. It might take some time to find it as it may not be as common as mainstream novels, but it's worth a try. You can ask the librarians as well, they might be able to help you locate it either in their collection or through inter - library loan if they don't have it on hand.
