Hmmm...

Some of the better ones actually have little Ranma/Senshi interaction for various reasons, but have both groups in it. All of the following I think would fall into this category:
- 'Negawarrior' by jimra
- 'No Need for Destiny' by Innortal
- 'Process of Elimination' by Brian Randall
- R-AA 'Ranma Saturn-Jurai' by Multiple
- 'Sailor Jupiter' by Daniel Jess Gibson and side arcs
- 'Dark King Ascending' by SoftRogue
- 'Relatively Absent' by Togashi Gaijin
Beacuse of that fact, I'm assuming they all would not count. Does not change I thought they were good stories.
