I've read two volumes, and i'm still not addicted.
the plot seems to be very simple; guy is rich and powerful, yet sad on the inside. girl tries to act out as boy, and is a complete idiot, yet powerful enough to kick most butt around her. throw in a few more suitors for either of them, and you've got enough misunderstandings to keep a whole season of ranma going.
also, the mangatraders translation has too man japanese words, there's no reason to leave 'gaki' untranslated, it means brat\kid, and having that complicated 'law abiding citizens son' japanese word is pointless, when you can write "a cop's son", it makes the reading unnatrual.
also, all the charecters are composed of above waist body parts, the guy's cheast has more body mass than the entire body of most charecters...
