The terms of Shogo Mikadono's late father's will are strangely specific: To claim his substantial inheritance, Shogo must first transfer to Miryuin Private Academy, find a nice girl from among the student body, and convince her to marry him. As twisted and unromantic as that demand may appear, it does seem doable, right? Unfortunately, there's an even greater moral obstruction standing between Shogo and a rich happily ever after, as one of the students attending the school is Shogo's long lost little sister... and he has no idea which one she is! Can Shogo navigate this minefield and find a future bride without committing a major sin? And if his little sister is revealed, will it be in a manner that's socially acceptable? Insanity is hereditary and Shogo's about to go sibling crazy in NAKAIMO - My Little Sister is Among Them!
