If you liked Ranma 1/2 then you'll also like Kasimasi. Both stories of love that transends gender without the same style of comedy or martial arts action, but more like sience fiction and real life type stuff.

Still awkward and uncouth, Teppei must somehow adjust to high society. With girls pursuing him at every turn, however, that may be the least of his concerns...
Both anime's are essentially the same with a leading role that inherits a family brand, multiple love interests chasing the lead, and unique female roles. Ranma 1/2 has less ecchi and more story but tends to go off into mini random arcs after season 2. Both Princess Lover! and Ranma 1/2 are fantastic animes and if you havent seen either take this recomendation both ways. Cause they are the same thing in a very good way.
A-ko is the brawn, B-ko is the brains, and C-ko is, well, C-ko. They'd make a great team, but A-ko and B-ko are rivals for C-ko's friendship, and if that wasn't confusing enough, there's an army of extra-planetary forces gunning for her too. The battle begins, though not without some comedy!
Besides sharing an 80s/early 90s flair that isn't around in anime anymore, these two shows are both excellent mixtures of comedy and action in the most over-the-top sense possible. Neither is shy about their silliness, and both contain plenty of un-accounted for collateral damage as well as warmheartes gags revolving around their characters. What makes both shows unique is that both the comedic and action elements are very well-done. Project A-ko is a healthy alternative as well if you only have time for a movie rather than an insanely long show.
