Story: 9, Art: 8, Sound: 9, Character: 10, Overall: 9
This ONA was incredibly witty, I think I laughed every single episode. It was kept very compact and well paced making every four minute story seem much longer than it really was. The art was of course chibi but very smooth. The backgrounds were oddly well done which I didn't expect from just a simple extra to a main series. Voice acting was superb. Music was appropriate for comedy's sake. I loved how it seemed to develop every character's other side, especially Yuki's "pastimes". A must watch whether you've seen the main series or not. If you enjoy humour, this is for you!
Parental Caution:
Rated PG-13
-Yuki plays H-games. You can only tell that she is because of the reactions of people who look over her shoulder and that the screen is censored.
