Princess Lover!

Princess Lover!

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...

A guy suddenly transfers to a prestigious school in order to become the head of a large, renown corporation. From being the son of the company president, everybody immediately knows who he is, earning him the attention of many pretty, wealthy and noble ladies. If harems, ecchi content, and the latter are your pleasure, watch the second.

Drasticc

Both of these animes have a strong ecchi feel to them. And the plots are very similar in reguarding a single highschool male being thrown in the lap of luxury, only to be surrounded by beautiful women. Great laughs and suspense along the way.  So if you like harems, these are great choices.

They both fall in the same catigory of a guy transfers to a prestegious school where he is to become the head for the corperation but they differ on the concept that in kono naka he has a sister while in princess lover he is an only child

Great animes to watch if your into harems with a lot of plot twist.  What makes these two animes special is that choices the protagonist amongst a group of high school girls. Yet only one may become his future wife! Ether its the small Tsundere type, otaku, voluptuous, even the forbidden sibling.

There are certain strong thematic commonalities between these two.  They are both quasi-harems in which most of the girls really don't matter and just exist for cover art.  They also both have strong sibling angles, though most will find the content of Nakaimo less objectionable.  Overall, it is the better show with a much more likeable protaganist, but if you like either, the other is sure to suit your tastes as well.

Onii-chan Dakedo Ai Sae Areba Kankeinai yo ne!

Akito Himenokouji and his twin sister Akiko are close - in fact, maybe a little too close for Akito’s comfort, as his sister has an unrestrained brother complex! Though her brother doesn’t take her lustful feelings seriously, Akiko is determined to set the record straight with the other ladies around him, including the three other beauties that live in his dorm and want the boy for themselves. Every morning, noon and night, the girl continues her mission to cross the line with Akito, and she won’t let any girl or sense or morality get in her way - for as long as there’s love, it doesn’t matter if he’s her brother!

These two anime have very similar themes- romance/comedy, harem, and incest. As the male lead tries to avoid sibling love, he ends up meeting a bunch of girls who become romantically interested in him.

zetazach

Both animes are about sisters that want to get with their older brothers; which, are also both harem series. While Onii-chan Dakedo Ai Sae Areba Kankeinai yo ne! has the sister living with him, in Kono Naka ni Hitori, Imouto ga Iru!, she remains hidden among his haren.

These two are all about characters attempting to shed light on which girl is the male protagonist's blood sibling and then being able to start a romantic, acceptable relationship with him. Just who is the sister? That's the great mystery to be solved while watching.
