Zepy's got a scan with more info on Shakugan no Shana: word is that after the recently-titled S OVA, there is a third season planned for TV. In fact, the OVA is being made specifically to tell some back stories that make the third TV series possible. The third TV season will also be the finale, closing down the popular story.
Meanwhile, on the Darker than Black side, a promo image with a new character has appeared! Not only that, but she appears to be a main character. She's 13 years old, half-Japanese, half-Russian, and her name reads Pavurichinko-- I wonder if she's named after Russian soccer player Roman Anatolevich Pavlyuchenko?
Actually, after spending some time on wikipedia, Pavlichenko-- as in Lyudmila Pavlichenko, a WWII Soviet sniper --seems more likely, or Dmitri Pavlichenko, an alleged assassin from the former Soviet nation Belarus.
So! Shana fans: are you excited or sad for the end of the series? And Darker than Black fans: what do you think about your new lead?
EDIT: And more, Lana brings up the possibility that the person at the top of the DtB image isn't actually Hei, whose eyes aren't red. Who do you think it could be?
