Animate.tv has been updated today with a new trailer and information on the Tethe'alla Arc's ending song.
The ending song will be by Akiko Shikata, who is also responsible for Umineko no Naku Koro Ni's opening theme and songs from Ar Tonelico III: The Girl's Song That Pulls The Trigger of World's Demise. The ending theme is called ????? (roughly "The Other Side of the Prayer", inori no kanata) and is also featured in the new trailer. Again, we can't upload anything related to the Animation in our YouTube channel due to copyright issues.
