Anime: Ouverture was animated by the same studio that did the other two seasons (Nomad), directed by the same guy (Kou Matsuo), and ran on Japanese TV from December 22nd to December 23rd, 2006. Again, this may or may not correspond to the manga; since I have yet to read it, I'll have to get back to you on that.
Story: Ouverture focuses on the first meeting between Shinku and Suigin Tou, mainly through a flashback as Sousei Seki tells the tale to Jun. The flashback part takes place back in Victorian England, and the modern day part takes place between episodes six and eight of Träumend.
Wow. It's amazing, seeing what a violent 180 everyone's personalities took to become what they are today. Well, everyone except the Sekis, really.
Still, I felt that something was missing from this OVA. But that falls more under Length. Overall, though, the plot for the OVA was pretty good, about the same as the writing for Traumend. Definitely dark, definitely revealing, but it felt like there could've been more.
Art: This is the pinnacle of the art that Rozen Maiden has shown thus far. The tones are definitely darker, and it's absolutely beautiful.
Music: No original music for this OVA; instead, it uses music from the previous two seasons. Except for the OP (again, done by ALI Project), which is probably my least favorite of all their OPs. Again, though, the ED (done by kukui) is made of awesomeness, and is my favorite of the three.
Length: The OVA really feels like it's missing something. The plot only starts picking up in the last third of the first episode, and it wraps up pretty quickly in the second (and last) episode. If it had been given an episode or two more, it probably would've had a chance to really shine. (Personally, I would've liked a whole twelve-episode series centered on Suigin Tou, but hey, that's just me. :P)
Seiyuu: Ouverture keeps the same seiyuu from the previous two seasons, so I don't feel the need to repeat what I've said the last two reviews.
Overall: Ouverture is a pretty good OVA, but it's not ZOMG material. Maybe if it had been given a few more episodes, it could've been.
