One day, after a visit to his parents' grave, Teppei Arima spies a damsel in distress, and nobly saves her from a gang of thugs. Relieved and grateful, she introduces herself as Princess Charlotte Hazelrink. Thinking nothing more of this, Teppei soon receives a surprise call from his grandfather, informing him that he is the heir to the Arima business empire and therefore one of the richest men on the planet! Teppei is introduced to his personal maid, Yuu, and various blue-bloods, among them his arranged fiancee, Sylvia - a fencer with a tongue as sharp as her blade. At school the next day, Teppei meets more new faces, including the snooty Seika Houjouin, and - much to his surprise - Princess Charlotte Hazelrink. 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...
In a world where magic is a reality, the young Louise is at the bottom of her class. Dubbed "Zero" by her classmates at Tristein Academy (due to her zero success rate for magic), Louise (along with all first year students) was charged with summoning a familiar; and instead of a cute magical creature, the familiar arrived in the form of... Saito Hiraga, a normal Japanese boy who was abruptly teleported from his own world?! Can both Louise and Saito come to terms with their new and complicated "relationship" and (more importantly) help Saito find a way home?
Both anime are a harem featuring a guy dropped into a life he didn't expect. Both anime also have plenty of fan service and ecchi moments, and the guy is surrounded by girls he often has to save.
Both a harem where the male is put into situations of rescue. Although Princess Lover is pretty perverted and a much more shallow plot you i think if you like on youd like the other.
When Hayate was young, Santa appeared in a dream and told him that if he worked hard, he’d be rewarded. Thus, with an unbreakable will, the unfortunate Hayate has struggled through life holding onto that belief. In the present, his parents are lazy and unemployed, forcing Hayate to work several jobs to pay the bills. As if things couldn’t get worse, Hayate’s parents then run away, leaving him with an enormous debt and loan sharks on his tail! Naturally, the best solution to find money fast is… to kidnap someone?! A girl named Nagi is the target, but due to an unfortunate miscommunication, she believes Hayate has proposed to her and falls for him hard. After Nagi paid off his debt, Hayate must now work as her butler in order to repay her; but first, he must adapt to her wacky world!
If you want to watch a fun anime about ridiculously rich people and you found yourself disappointed with Princess Lover!, you could give Hayate no Gotoku! a shot. While it also features harem, school setting and some fanservice, it is actually enjoyable for a change.
Akuto Sai enters the Constant Academy for Magick Arts hoping to become a high priest and change the world for the better. But when the school's oracle declares his future profession to be 'Demon Lord', he finds himself feared and hated by the entire student population. Now, instead of making comrades and studying for his exam, Akuto finds himself fighting off monsters, bullies, and well-meaning classmates in various states of undress. If navigating a magical high school as a transfer student wasn't difficult enough, Akuto now has to deal with a cute android ordered to observe him 24-hours a day, the precocious attention of the flying, invisible and naked Keena Soga and the advances of the school's most popular girl. Will he be able to overcome his fate, pass his classes, and mend his friendship with the violent Junko Hattori, or will he succumb to his demonic destiny?
Both start off as comedic harems with a decent dose of perversion and deviate to a serious plotty show that cuts down on the comedic perversion for drama. Both are much better as comedies but have their merits with a good-hearted protagonist, some pretty funny moments and chemistry among the characters.
Both of these anime are very similer as they both have a Main Male Charicter that is transfered in and then has to work hard to make a diffrence/point, during this time they have a group of girls fall in love with them.
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'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.
