Good Luck! Ninomiya-kun

Is insanity hereditary? Shougo Mikadono's beginning to think so, because the terms of his late father's will seem crazy and following them may drive Shougo bonkers as well. Oh, it sounds simple at first: before Shougo can claim his VERY large inheritance, he just has to start attending a certain new school and find a nice girl to marry. It's a little unromantic, but perfectly do-able, right? After all, all the girls seem quite friendly, so all Shougo has to do is find one he has something in common with. EXCEPT, and here's the kicker, it turns out that Shougo has WAY too much in common with one of them, because she's actually his long lost sister! And he has no idea which one she is! Will Shougo meet and court his Miss Right without committing something very morally wrong? Can he find his future bride without slipping into the wrong set of genes? And if his little sister does reveal herself, just how much will be revealed and under what circumstances?

In a hidden school surrounded by mountains, young ladies of good families are taught everything a high class lady needs to know. They are also completely cut off from the outside world, keeping them sheltered and innocent. However, a problem has come up recently—more and more graduates are failing to cope with the modern world after graduation. To deal with this problem, they've decided to kidnap a male commoner student, and enroll him as a student. They hope that this will be a gentle way to introduce the girls to the outside world. Kagurazaka Kimito is chosen for this dubious honor, mostly because he seems utterly average. However, the school leaders also seem to have concluded he's a homosexual with a muscle fetish. When Kimito hears that the alternative may be castration (to protect the girls' purity), he eagerly plays along with this misconception. Now he'll just have to survive the attention of many high class young ladies that are completely out of touch with the world!

Izumi Sawatari and her younger sister, Mitsuki Sawatari, have run away from home and are in need of employment. The only jobs available are as maids in the mansion of 14-year-old millionaire, Yoshitaka Nakabayashi. What seems like simple work is soon revealed to be far more than the girls bargained for when they find Yoshitaka to be an authoritative employer who demands they call him "Master".

When you've got acute gynophobia, even a pretty girl can be a malady, and as the sparring partner for his family of female wrestlers, Sakamachi Kinjiro has the worst case EVER! Just one touch makes his nose bleed, so school's a bloody nightmare even before Kanade, the Principal's twisted daughter, deduces both Kinjiro's "feminine issue" AND that his name contains the sounds "Chi" and "Kin" back to back. But Chi-Kin's female troubles don't totally redline until a wrong turn in the men's room exposes the secret Subaru, Kanade's manservant, has been hiding in the water closet. (Well, to be fair, we should say WOmanservant.) And if Subaru's cross reactions concerning her cross-dressing aren't enough of a drag, Kinjiro's girl problems also include a haunted martial artist (with ghosts); a cat-eared fetishist (meow!); AND his own sister, whose interest in "wrestling" a certain incorrectly packaged butler may result in an unexpected ending! And that's JUST the set up!
