Variety has confirmed that a live action adaptation of Production IG anime, BLOOD: THE LAST VAMPIRE will be helmed by Ronny Yu (Fearless, Seed of Chucky).  The plot follows a young demon slaying female vampire (think hard core version of Buffy).
Now that TV series of the same title is aired and out on DVD, its popularity is at its peak. So no wonder they are trying to crank this up.
