New teaser?
Just ran on that while browsing YouTube. Guess it's new, since it has the 2009 release date and the artwork that's being used on the website.
Anyway, if that's the OP, it sounds good. Really love MELL. Looking forward to this ever since I read the first volume of the manga. Shame there isn't more >:3
EDIT: Is there any word on who's doing the OST? Curious about that.
