Hmm. I see various theories about Bina(h)'s true identity. So far, I'm liking the thought that she the possessor of one of the remaining two Longinus out of those proposed.

However, I have another suggestion - though it doesn't necessarily completely exclude the former. The new "Seven Great Satans" is known that it will have a Belial, a Belphegor, and a Mamon added to its ranks. And yet, we still have yet to be introduced to anyone from the House of Mamon. Perhaps she's the future Satan "Mamon", or perhaps she's a youth from that Extra Demon house
