If Babble fish is to be trusted, then the blonde one is the leader, Sadako is the cute one, and older dark haired one is the whore. Also, the evil one appears to be a government weapon of some sort. It doesn't sound all that useful, but hey, they're not my tax payer dollars. Also, it looks like Sadako's supposed to come from the american version of the film, which means that they're keeping continuity, kind of, around all three films. I'm not sure why, but I think that's really cool.
Also, unless that cover of Newtype was photoshopped, then this is probably going to become a real OAV.
