Okay, so here is my review after watching Tsubasa Tokyo Revelations all the way through, and yes that includes the final part. Spoilers will abound, so don’t read further if you don’t want to be spoiled.
First, my impressions of the third OVA. Wow. More consistent overall, and some great scenes. Anything with Yuuko in it — they did a great job with her wherever she showed up. The scene where Fai becomes a vampire was very well animated. And Sakura’s scenes where she goes off to get payment for Yuuko, also very well done. Great character development from Fai and Kurogane. I just love the way Kurogane strips away Fai’s mask repeatedly.
And the big surprise, the inclusion of Sakura from Card Captor Sakura. This was not in the manga. This convinces me even more of the connections (more so than with anything else CLAMP has written with the exception of Xxxholic of course). Now all we can do is hope that CLAMP will finish the series and have the chance to animate more of it too:)
Overall, I enjoyed the OVA more than the first two seasons. Part of it is the story. It isn’t the seasons’ fault that the OVA got arguably the pivotal point in the story. The animation isn’t perfect, but overall is better. And I love the fast pace of the story. The seasons basically did one manga chapter per episode. In the OVAs, we get one tankubon per episode. You can argue that not all of the story would work as well at such a fast pace, but for such a pivotal part it worked perfectly.
For those who have only scene the two series, be warned the OVA is much more violent and intense. For those who have read the manga, this is an excellent addition to the Tsubasa cannon. And for those who are discovering Tsubasa for the first time through the OVA, well previous knowledge probably does help some, but is not required.
