You can try looking on fanfic websites like Archive of Our Own (AO3). There are often various fan - created stories, including those related to sakura and yakuza themes. Just use the search function and type in relevant keywords like'sakura yakuza' and it should show you the available fanfics.
I think a community - based online platform like Nextdoor could be a top choice. People in your local community can see your post about the used novels for sale. It's convenient because you can arrange for local pick - up, which saves on shipping costs. And since it's local, there's a higher chance of finding someone who really wants the novels you're selling.
Local comic book stores might be interested. Some of them buy used graphic novels. You can also check out second-hand bookstores in your area. They might take them if they think they can sell.
Online marketplaces such as AbeBooks are great for selling used novels. They have a large customer base of book lovers. You can easily list your books and reach a wide audience.
The first place to look would be Archive of Our Own. It has a very organized tagging system, so you can search for 'Judge Eyes' and 'Yakuza' crossover easily. Some individual blogs of fanfiction writers might also host such crossovers. You can find these blogs by searching for relevant keywords on search engines like Google, combined with 'fanfiction'.
