My orginal idea

I want to her suggestions that you guys have or requests. I'm currently thinking about doing a story about my demon slayer oc, but I want to know what you guys would be looking for in a story. I am new to writing so I might not be the best, but I would love feedback and help whenever I can get it.

I don't own demon slayer or any of the orginal characters mentioned from demon slayer. I'm just writing fanfiction based around the anime
