GeneralTrash might be of particular interest to you c:

there's going to be some higurashi gou/sotsu spoilers in this plurk if... anyone cares. but satoko is essentially going to run into the part of herself that will become lambdadelta, the concentrated malice and certainty and nihilism necessary to become a witch of certainty. on an arc level this is kind of important for her because it's going to be something

she will deny the existence of vehemently, claiming that any memories it has are falsified or saying it's a case of demonic possession, but her other self will well and truly remember eeeeeeverything

including every single event in the main higurashi story, no matter the perspective character. so she'll recognize keiichi immediately and probably toy with him a bit. if anyone tries to get in the way of witch satoko (we will call her SATOKO) trying to kill satoko, then SATOKO will try to kill them without a scrap of remorse, since as far as SATOKO is

concerned, they're all pieces on a gameboard with no real agency.

pending any intervention i think my ideal way for this to go is for SATOKO to shoot and kill satoko and then someone else to crazy murder SATOKO in response.

oh boy crazy murder, you say?

crazy murder!!!
