Even if you don't play the game, you'll enjoy this book on a purely nerdy level. It features a lot of asides and nods to not only otaku culture but roleplaying as a whole, as well as a plethora of anime references. There are a few "sample" characters wandering around that are really a great representation of the fun that can be had, even if you're creating characters on your own, and not actively getting a game together.
From a fairly brief scan of the book-- I purchased both the PDF and the physical copy-- I found the art to be charming, despite being a little sparse, and the gameplay relatively easy to pick up. It requires few die or supplies, so you don't really have to do a lot of work to set up. Once you have a scenario in mind, you just follow the tables in the book to flesh it out and go to town with maids either randomized with dice rolls or completely customized, from their hair color and uniform of choice down to their personality and type.
There is some combat, but the crux of the game is pleasing the master (or mistress, as the case may be)-- who is the equivalent of the DM, sporting a character similar in construction to a maid but with different rules and autonomies. In some game styles, the 'master' is omitted entirely, or played by everyone, allowing each player to have their own character.
