The four episodes are great - the artwork is beautiful, the characters are interesting and the combat is realistic. There are wheels within wheels when it comes to the plot and there are two story arches within the DVD,so you get a lot of story for your buck. The main idea is that crime rules most of the city of Tokyo and a team of four girls are trying to help keep the peace. But they are NOT part of the normal law enforcement units (think A-Team or Bubblegum Crisis). Rapt seems to run the city, but there are hints of other powers fighting for the top of the hill. In fact the girls seem to follow commands from somebody else (all we get is a name - it could be a person or a business).
There are also a ton of extras, such as radio dramas, one commentary track, funny outtakes, textless songs and, of course, trailers. The English Voice Actors are the best. Jo is played By Monical Rial (Gasaraki, Azumanga Daioh), Meg is played by Jamie Marchie (Fruits Basket) and Kyohei Tachibana is played by Greg Ayres (Full Metal Panic, Gunslinger Girl). We also get Sei played by Clarine Harp and Amy played by Alison Retzloff (from having been in Kiddy Grade).
Now, heres the bad new. First, it is ONLY in surround sound, so for guys like me who have only 2.0 stereo, lots of the audio is lost or too soft. Also, there are subtitle problems. The opening song, for example, has the subtitles right over the credits. The radio dramas, but for the first selection, have non subtitles. Also, the textless closing song in the extras, the English version, has subtitles which can't be turned off. All this little issues add up and take a little away from the enjoyment.
Yet hearing Monica Rial play a female gunslinger, with cussing and all, made my day. That is why I only took one point away. Great anime, nice selection of extras, but sloppy work on putting the DVD together.
