I'm starting off the season this time around with a look at some sequels to series I haven't watched, some short shows that don't really hold up to in-depth scrutiny, and series meant for young children. There are a larger number of sequels this time around than I'm used to. While I could probably count Fate/Zero amongst them since I attempted to watch Fate Stay/Night multiple times without much luck, it appears to me that its tone is separate enough that it will most likely get its own entry.

There are some long-running series that are relatively easy to step into blindly, like Natsume Yuujinchou. Then there are series like Shana which are so completely full of complicated character relationships and jargon that it's nearly impossible to start watching at any place other than at the very beginning. That in itself isn't necessarily bad, but with the various seasons of the show and its OVA incarnations having been released so far apart, it would be difficult to expect all but the most hardcore of fans to keep everything straight. As you've probably already guessed, I'm far from a hardcore fan (in fact, I've seen 3 episodes of the franchise, and that includes this one).
From what I can gather, the male lead of the series, who was himself just a recreation of a real person who had already died, has vanished from existence. Shana and some of her close companions are certain that he's not really gone, and intend to do what they can to find out the truth and bring him back. Additionally, other factions are... up to something. There's some reference to different worlds that art at war, there are a lot of people in funny costumes wandering about both the real world and the alternate one, and the whole ordeal is incredibly difficult to piece together by a newcomer like myself.
At this late hour I can hardly chastise a show's creators for assuming that the audience for the show is already full of dedicated fans, and this episode is clearly aimed at those people. It's also competently animated and features very little of Rie Kugimiya's shrieking, which is a definite plus. But I'll be darned if you don't have your work cut out for you if you decide you're interested in knowing what's going on; this is definitely not for newcomers.
This series will be streaming at a future date as a result of Funimation's streaming partnership with NicoNico
