The OVA anime release Marriage consists of two 30-minute pieces by Miki Kasamatsu on the topics of love and looking for that special someone. The first deals with a group of young women who, after being out of school for a few years, are beginning to think about settling down. However, there is one member of the group who has no prospects, and Shizuka's friends are worried that her shyness will keep Mr. Right from noticing her beauty and character. They persuade her to join a dating service called The Wedding Club, but when her first match seems to be quite a dud, Shizuka wonders if a trip down the isle just isn't in her future. The second episode is about five sisters, only one of whom isn't married. What's more, the cool Kiyomi seems to have no interest whatsoever in finding a husband. Her sisters have other ideas, though, and when a co-worker asks her out on a date, the women convince the suitor to propose marriage that very night.This is easier said than done, however, as Kiyomi's attitude can be quite intimidating. The young man may not end up following through with the plan, but even if he does there is no guarantee that the headstrong lady in question will say yes.

OVA Bundled with the first volume of the BD/DVD.

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?
