The woman is credited as Raven, and that's the place we initially got the name from. So yes, she almost certainly is. As for the woman in the Vol3 opening's photo, she's almost certainly Raven as well, unless there's an explanation for them having the same outfit and also the same weapon in a series where everyone who isn't a mook is unique.
