Thirteen Constellations, eh? I like it. Would each of the bearers of the title be associated with a particular constellation? Would sort of make sense from a monitoring perspective, those who know they are so-in-so constellation (Like, say Kōsa the ) could consider it just a larger part of their identity to the world as a part of the Juusanseiza, while for Central 46 it could be a Kidōfied tracking device / identification tool so that they can talk about these dangerous figures without worrying about anyone actually knowing who they're talking about.

Kanji for the name, in case we're missing it/Njalm is keeping it for a nefarious scheme: Jūsanseiza (十三星座, Thirteen Constellations).

I'll also throw Fiona/Emi at this as a possible candidate, because Pablo is just too OP to be a member.
