Hope there are some stories in there that you like and if you like the stories from a certain community you can subscribe and receive updates when they add a new story. I don't know that you'll like all the stories, but thought you'd find some you like. I wasn't able to find any nejikiba or kibaneji communities, sorry. I don't know how many of these stories are finished either as I just looked at what the community included for the most part. *shrugs* Don't shoot me if you don't like them. Just read what you do like and ignore the rest. :D
