Hrm.
The source of CatsTMGirl-chan’s fur-stration seems to be NyanChan-chan attacking them saying they don’t believe their jester read (and that it is therefore fake)
I find the source of this frustration to be probably genuine, as when told their jester-read was fake they directly challenged it instead of backing off into some weird land.
This slot is probably nyat jester just based off of this. Additionally I find it unlikely that it’s partnered with NyanChan-chan because they’d have no reason to get frustrated at NyanChan-chan’s insistence that their read is fake, because NyanChan-chan would know that it’s fake and that frustration, even through theatre, wouldn’t be as focused because CatsTMGirl would know NyanChan is pushing off of a real basis.
