It's actually the Qlipot... so they actually correspond to Yesod and Chokhmah... I think
You might be correct, so good catch on that. edit Yeah, you're probably right, I missed the parts of the pendant that are missing at first. Also, yeah, the top part seems to be Yesod (foundation) and the other is Chokhmah (wisdom/intelligence but in a different manner to that of Binah)
I still can't be too certain about the whole qlipoth thing, since it doesn't seem to have a representation like the sephiroth's tree and no set-in-stone opposites as far as I'm aware. I'm also not sure why Malkuth (majesty) is completely absent, but I guess we'll see.
I mean, honestly, the whole thing is messily introduced to say the least lol. With how gibberish the Hebrew is, I can't take it all too seriously, really.
Reading a bit and holy crap the whole concept of the qlipoth is arbitrary to a wholly separate level of amusing. For some reason, Fire is in direct opposite to the sephiroth. God is pyrophobic, I guess.
The Qliphoth in that shape seems to be used in "demology" and other such things that don't have much basis in Jewish mysticism, rather they tend to stem from Christianity and occult stuff that came from Christianity
Just from looking at it a bit I saw stuff saying the Qliphoth each represent different demons, which is what I'm guessing this is going for considering a lot of them seem to put Beelzebub on Chokhmah's place (and Beelzebub was the demon they fought before that part of the pendant light lit up when she kissed Yukina) and while we didn't get a demon with Karen I saw most stuff associate the bottom bit with Naamah who is supposed to be a succubus, i.e. a demon who feeds on desire, and Karen's thing was granting everyone what they desire.
So I'd say, try not to think about it from a Jewish perspective. It's probably more based on the bastardisation of the Christian bastardisation of the original concepts
