The moment Rika warns Kisaku about the future he kills her…
Suspicious unless you read Umineko When They Cry Episode 7 Requiem of the Golden Witch…
Kisaku’s wife despite claiming to be Satoko doesn’t look like her and looks more like Natsumi Kimiyoshi with Sakiko resembling Satoko more.
Natsumi…Natsuhi… Demon Personality similar to Witch Satoko who insists she is the real Satoko who looped to chase after Rika…
In Umineko Episode 1 Legend of the Golden Witch Kumasawa San who in some Gameboards is the first Golden Witch Beatrice is killed in the same room as Maria shortly after Kanon died while she was in the same room as him. Similar to the fates of Eua and Fake Hanyuu(being eliminated by Eua before randomly appearing and defeating her).
Jessica and Kanon die in the Episode 2 Turn of the Golden Witch in a way similar to how Tsukuyami Rika and Hanyuu do in Higurashi Mei: in each other’s arms(merged in the case of the Tsukuyami) with Kanon/Tsukuyami Hanyuu dying shortly before their original(Shannon in Umineko and Hanyuu in Higurashi Mei) disappears from the story.
Maria(who has Hanyuu’s Voice Actor) represents Featherine in Hanyuu form while Kanon represents a fake Hanyuu and Shannon represents Real Hanyuu. Kumasawa represents Eua and(when she is Virgilla) Featherine Augustus Aurora the First Beatrice.
Jessica represents Fake Rika in most cases born from Natsumi for the sake of following Gou Rika to Saint Lucia’s despite her hating the place, Kinzo represents Rika before she split into Battler Rika and Ange Bernkastel Beatrice(the 2nd Beatrice AKA the child of the 1st Beatrice Featherine Augustus Aurora and Kinzo) and Tohya represents Original Rika resurrected and sharing a body with Bernkastel and Battler.
Natsuhi AKA Natsumi is the Witch who poses as Satoko for Gou and the true identity of Vier Dreissig. Lambdadelta represents Eua and the rogue extension of herself Gou Hanyuu.
Higurashi Rei’s Rika is the Gou Rika(created alongside Battler Rika and Bernkastel Rika) who after being killed by Kisaku’s true identity Rudolph Ushiromiya is supposed to become Lion Ange Beatrice Ushiromiya from Requiem of the Golden Witch and Twilight of the Golden Witch. The final loop of the Rei Manga will be into a Body that is red haired so as to distinguish her from Rika/Battler, Gou Rika/Jessica(who has glowing Red Eyes), Bernkastel Ange Clair Yasuda Beatrice(the 2nd Beatrice who was imprisoned by her father Kinzo AKA Rika before she split off from her becoming the 3rd Beatrice who at times posed as Shannon AKA Oyashiro-sama) and Erika Furudo(who has lighter Blue hair) who all aside from Rika/Battler are given Clone Bodies.
Upon discovering her origin Lion Ange Beatrice Ushiromiya will off herself and find herself in the Sea of Fragments alongside Eua Lambdadelta Kumasawa Bernkastel and Featherine Augustus Aurora and be forced to find the Book of One Truth AKA Takano’s Diary which confirms that she is indeed a Clone of Rika with seemingly no looping powers(without Jessica Rika at least) to test giving Looping to others.
After Higurashi Rei will come none other than Higurashi: Twilight of the Golden Witch which won’t even hide it’s true identity since the cat will be out of the bag.
I’m sure that once it’s made clear that Higurashi Rei is the Requiem of the Golden Witch in Higurashi Manga form there will be a Higurashi: Requiem of the Golden Witch Anime which will combine Higurashi Rei’s two Mangas into one.
I’m sure that after the cat is out of the bag Higurashi Mei will also get renamed Higurashi Mei: Turn of the Golden Witch and get an Anime Adaption and feature the final showdown against Featherine Augustus Aurora in her original identity of Beatrice the Golden Witch(before she gets harvested by Eua for EVA-Beatrice’s creation in Banquet of the Golden Witch).
