Reading a book is innocent enough, right? Except when you're Pita, and reading the book releases hundreds of demons and their leader, and all of them are craving for a bit of...action. Enter a (pig) cherub-in-training named Buhi, who then puts Pita in a contract to take care of each and every one of the demons, add a little bit of Magical Girl bibbity boo, and now you have the start of the story.

Wilson Kane wins a fortune and his future bride at a game of dice. When he decides to go and get the girl not only he finds out that she is more than a pirate could ever want from a wife... but that she has 4 identical sisters as well.
