This is a rewrite of book2 for those who hate Ranma/Ranko splits. Actually, it is a rewrite of book2 because of certain ideas that occurred to me as a result of the complaints of those who hate Ranma/Ranko splits, but what the hey. Details, details.
Anyway, the first few chapters actually backtrack and rewrite the ending of book1 slightly, so if they look disturbingly familiar... that's why. No, it's not plagiarism. It's my own work, for crying out loud. ^_^
