I think I have a good idea where Higurashi When They Cry Mei is going:
I think that someone is attempting to reenact the Witch’s Epitaph of Umineko When They Cry
The 4th Twilight was Kazuho being shot in the head, 3rd Twilight was Fake Hanyuu praising it’s name as God, 2nd Twilight was Rika being separated from Hanyuu creating Black Witch Rosa who erased normal Rika’s existence for the sake of taking her place and the 1st Twilight was the Rokkenjima Massacre itself I.E. the day Rika got hit by a Truck.
On the 5th Twilight the culprit of the 1st Twilight will reenact the Rokkenjima Massacre and get killed by her other half Eva again this time being gouged in the Chest and killed.
The Massacre will be reenacted thus: Eua’s Hanyuu will get into an Argument with Rika’s Mother and Hanyuu will be forcefully pulled out as Featherine which leads to Teppei getting into an Argument with Rika’s Father resulting in him ultimately stating he is actually supposed to be dead causing Featherine to drop him resulting in him dying instantly causing Black Witch Rika to show up ranting that she will tell on everyone.
That will cause Featherine to unload some of Rika’s Mother on Black Witch Rika recreating Chloe Ironside before first exposing Teppei as Eua Hanyuu’s Game Piece followed by unloading the rest of herself on Eua’s Hanyuu(who would dump the normal Hanyuu traits back on Hanyuu) thus turning back into the real Hanyuu then she will turn Kazuho back into a Hanyuu. Mion/Shion will be removed from Rika causing the Mion/Shion traits to move to Mion who will go berserk and have to be killed.
The matter of Rena’s Crimes will force Nao and Reina to separate from their Bodies as Oni leaving Rena to the mercy of Featherine who will break the Sword that kills Loopers I.E. Kumasawa-San in order to pull her execution of Rena(just as Hanyuu as Featherine broke Kumasawa-San in order to off her true Body) off followed by transferring herself to Eua so that she can be killed by Eua-Hanyuu who would Gouge the Chest and Kill with the Sword that slays Loopers.
The Culprit of the Witch’s Epitaph won’t care about the Rokkenjima Massacre being reenacted on the 5th Twilight as the Culprit is simply going for the traditional Epitaph with the intent of becoming God.
Since Kazuho will be saved despite having her Tamurahime-infused Guts removed and consumed the 6th Twilight will focus on the Culprit successfully consuming the Guts of the 6th Twilight’s Victim who might be anyone.
After that is Gouge the Knee and Kill(7th Twilight World) and Gouge the Leg and Kill(8th Twilight World. The fake Midori Kawata will have to give up her power and die in the 7th Fragment as will the other accomplice of the Culprit on the 8th Fragment.
The Culprit(who already has Hanyuu’s form) will have the power of Tamurahime and another Victim combined with the power he/she temporarily doled out to his/her allies allowing him/her to revive as the Golden Witch herself at full power before killing the inhabitants of the 9th Fragment before the Protagonists using the gate reach the Golden Capital: the Tenth and Final Twilight.
I dare say we will also get an Umineko Crossover Reenactment of the Rokkenjima Massacre for comedy’s sake where Erika will notice Keiichi with Krauss’s clothes(and when using Detective Vision notice he has a cloth on his head), Teppei with Hideyoshi’s clothes(and also have a cloth appear on his head when Erika looks at him with Detective Vision) and Rena joining Rika and Nao as a Winchester.
Beatrice will show up and point out that the Fragment’s Bomb is not detonated yet while Erika will claim that Rika is a doll causing Eua Hanyuu to get in an argument with Rika leading to Featherine, Mion/Shion and Black Witch Rika’s exposure causing Rika to suddenly wear Natsuhi’s clothes leading to Keiichi demanding Teppei remove the cloth on his head before Teppei angrily removes the cloth on Keiichi’s head revealing a skull.
Eua Hanyuu will reenact her panicked insistence that the World be destroyed before Black Witch Rika insists on tattling on the fake Hanyuu followed by Featherine turning her into Chloe Ironside on the spot followed by Featherine removing Teppei’s cloth exposing him as a skeleton.
Eua Hanyuu will start unloading the Hanyuu part of herself on Featherine who will return the Hanyuu parts to Eua Hanyuu creating Featherine who will promptly remove the Mion/Shion transformation from Rika and murder the Metaphor Jessica, Maria(while explaining how the murder of the Real Maria was Hanyuu-Featherine killing her Hanyuu Body in order to Loop into the Hanyuu inside Rika’s Mother), Kumasawa, Genji and Nanjo before transferring herself to Eua causing Eua Hanyuu to revive and break Featherine’s Horn yet again as the Goats come in to eat Rokkenjima signaling the end of the Catbox as Eua Hanyuu takes everyone back home to Hinamizawa on the boat at Kuwadorian.
Injured Featherine will become Ange and revive the Metaphors(starting with turning Eua Hanyuu into Lady Maria) despite the Catbox being Metaphorically destroyed.
