Ranma, raised to be a man among men, has a bit of a problem: he is half woman! While training in China he fell into a strange magic spring at Jusenkyo. Now, he is eternally cursed to change into a beautiful woman whenever he is hit by cold water, but that may be the least of his problems; his father has betrothed him to marry! There's never a dull day for Ranma as he attempts to find a cure for his curse, train to become stronger, and grapple with the fact that half of himself may be more feminine than his fiancée!
Both anime series are hilariously chock full of ninja mayhem. Also, both male leads have an insurmountable amount of strengtbut yet are rather dense at times (especially when it comes to their own feelings). Both female leads are also very similar in that neither one really cares for their new living situations, but are strong-willed yet caring. If you like this series, then you will definitely love the other one!
Ataru is one of the most desperate womanizers alive, and a man whose life is about to become complicated. When aliens invade, he discovers he has been chosen at random to be mankind’s defender, and must play a game of tag with the beautiful alien princess Lum to decide the fate of the planet! After chasing her with all of his crafty techniques, Ataru finally wins, but his victory also means he must marry the princess herself! Now, with strange alien visitors and a jealous wife to handle, Ataru still manages to keep an eye on his ultimate goal: having his own harem!
Protagonists Moroboshi Ataru and Igano Kabamaru share a love of food, sleeping in class, girls, and making the most of their school days. While Urusei is vastly superior imo, fans of the comedy in one may like the other of these early 80's anime.
