Tofu asks Ranma for help in diagnosing a patient due to Ranma’s high level ki control. Ranma dresses as a candy striper and sees the patient, she doesn’t like what she sees. She checks again a week later and it’s even worse. Hotaru’s ki is like a well that has no way of filling, it’s cut off and she’s using it without it filling up again. She has very little time left so he uses his ki to force open the pathways. For a time it worked, but after transforming into Sailor Saturn, the blockage is back stronger than ever and Hotaru soon dies. Ranma is devastated that he couldn’t save her, when queen Serenity’s ghostly form visits him and explains what happened. Ranma offers to be a replacement, knowing it will fully change him into a girl. Ranma becomes sailor Saturn and helps out the Senshi. (Sailor Moon Crossover.)
