I'm looking to put a few of these characters together for a little something. While, technically, I wouldn't really count Ranma for what I have in mind, because his like of ice cream is rather flimsy, I'm going to include him for the comedic factor. The girls I've thought of so far are:
Ranma (Ranma 1/2)
Skuld (Aa! Megami-sama!)
Tsukino Usagi (Sailor Moon)
Shidou Hikaru (Magic Knight Rayearth)
I feel like I'm forgetting one, but that's what I'm hoping you guys can fix. One or two more will do.
