I have a search for a change...
Since I just finished watching it, I'm looking for Princess Lover TV fan fiction (I've seen the Game opening, and seen a trailer and the OAV series as well as the main TV series).
It can be straight fan fiction, or crossed over with another series such as Ranma or Fate/Stay night or Revolutionary Girl Utena (others fine, just listed likely and desired examples).
To the best of my knowledge, I've read exactly 0 stories with this series in it.
