I doubt you're still looking at this, but I wanted to say that I looked into .UNI files (I wanted to rip Hakuouki's sprites, backgrounds, etc. as well) a while back and the only tool I found that claimed to be able to extract from .UNI files came from asmodean. I myself wasn't able to get the tool to work, it just kept giving me errors (I believe it was something like "This application has requested the Runtime to terminate it in an unusual way"). In the end I gave up.
The tool was designed to work with another game from the same manufacturer as Hakuouki, so in theory it should work. I guess...?
That's... about all the help I can offer, unfortunately. I'd be really interested in these rips if anyone can get into that file though. o/
