I'll wait for episode 15 to come out so I can watch 13-14-15 in one go.

Hey guys, you know that show, Bakemonogatari?
Yeah, it's wonderful! Too bad SHAFT is in the habit of, y'know, not finishing the damn thing. Shame. Anyway, that just goes to show how great it is, that incomplete episodes can still be so awesome and sell like gangbusters.
But enough about me gushing, here's what you need to know. The next unaired episode of Bakemonogatari will be streaming on Friday from this website. The legions of future Blu-ray and DVD buyers will also be pleased to know that the unaired eps will be included in further disc releases. Which means they will probably be complete by then.
It's the next part of the Tsubasa Cat story arc, which stars Tsubasa Hanekawa, the seventh most popular character in the show, and her possession by a cat who makes her speak with "-nya"'s. That automatically makes the cat one of the best cats ever, because the voice actress behind those "-nya"'s is Yui Horie, a legend and personal favorite of mine. She also played Love Hina's Naru and Persona 4's Chie.
Anyway, it was scheduled to go up nearly a month ago, but SHAFT pushed it back again. Oh SHAFT! But I'm willing to forgive them if this happens to be the episode with Tsubasa's custom OP. Can her character song beat "Ren'ai Circulation"?! I hope so! That'll show those Nadekcon who's the real class president.
