Ok, first of all I uploaded both this and the identical-but-smaller post #80411. The reason for this is that the site kept crashing when I tried to upload this pic despite being fine with the other pics I uploaded today. I thought I'd change the dimensions of the image (from the original 640x640 to this 1000x1000) in case another similar image already existed and danbooru thought it was a dupe (4chan has this sort of rule).
Well anyway, it seems the earlier attempt to upload the 640x640 one DID work, though it didn't show up at the time, as usual. So if any mods want to delete either of the pictures that's fine by me. As I said, this one is just an enlarged version of the original one that can be found at the link above.
Secondly, does anyone know the name of this Arrancar? I'm not sure if she's been named yet though she's only been seen a few times and has only one line IIRC.
