Wow just as I thought...
Hey if I'm not wrong, maybe my theory about thinking of things indirectly according to higurashi will work!!!!

Spoiler for My theory to end the Witch's rule:

According to Higurashi:

Onikakushi-hen: Neck-Scratching, solved reason as Hallucinations
Watanagashi-hen: Stomach-Opening, solved reason as Mi/Shi-Body Swap
Tatarigoroshi-hen: Curse-Killing, solved reason as merely coincidence

and just like Umineko:

EP1: "Face-off"
EP2: The great halloween feast
EP3: ???...I don't know yet

Yes I did realize that Cotton-Drifting didn't occur until Tatarigoroshi-hen
but Shion(Disguised as Mion) did mention to Keiichi on the 'Surgery bed' about the Cotton-Drifting

So maybe we can use a similar logic according to the chapters of Higurashi
But since Ryukishi is a genius, he would definitely know better than to make it alike too much
