Does [SPOILER] have their own [SPOILER?] counter?
Basically, my question is, does >!Nishinomura have their own Break and Seal counter?!<
Because we know that up until 400 years ago they were "dedicated to producing chosen twins", so they must have expected to have Break and Seal and some point, but despite that, Sayuu was in posession of Higashimura at that point, because the Higashimura lord had the jade necklace.
So, do you think they have their own counter, something equivalent to Sayuu? If they do, my hypothesis is that it would be something like "up and down", based on the expression 上下左右. Which, thinking about it, could apply to Heaven and Earth, Misasagi's tsugai. And speaking of Misasagi, his coulouring looks too much like Right and Left. I would wonder if he himself was the counter if Jin's bullet hadn't graced him (because we know Right and Left are inmune to bullets).
Or maybe the Nishinomura twins wouldn't get Break and Seal but something else altogether and they have the counter to that? The prophecy Asa recites does say "in an eastern village", it says nothing of Nishinomura twins.
Thoughts?
