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. Unfortunately in Shougo’s case, that Ms. Right may end up being a little TOO familiar…as in, familial! Can he find his future bride without slipping into the wrong set of genes?
