After Hotaru is turned into a baby the scouts don’t find her and assume she’s dead. Akane knocks Ranma into Juban and he decides he’s had enough of the fiances so he decides to leave. He lands in the ruins of a school and is visited in his dreams by the Kami of Saturn who shows him Hotaru’s life. Ranma agrees to become an avatar of Saturn’s moon while the spirit of his curse will be another, together they will raise Hotaru and protect her from the outer Senshi who want her killed. Badly written but interesting. (Sailor Moon Crossover)
