Speaking of Anime I hope we get Anime of Higurashi Mei and of the Rei Manga which I’m certain are the backstories of Umineko’s Battler/Beatrice/Lambdadelta(Mei would be that backstory), Bernkastel/Ange Ushiromiya/Erika Furudo(the Rei Manga would be that backstory) as well as the rest of the backstories of George Ushiromiya(in Higurashi Mei), Jessica Ushiromiya(in Higurashi Mei) and Natsuhi Ushiromiya(in Higurashi Mei).
Yes I’m suggesting that Higurashi Mai Rika is Beatrice(Une), Shannon(Rika possessing Hanyuu), Kanon(Rika possessing a fake Hanyuu), Lambdadelta(Rika in her Nippah persona) and Battler(Rika’s body) while the Rei Manga Rika is Bernkastel.
Natsuhi’s name sounds a lot like Natsumi a scientist in Higurashi Mai and since the order of exits from Higurashi Gou are so similar to Umineko Episode 1(Eua is defeated by Hanyuu at the same time Dr. Nanjo, Kumasawa San AKA the First Beatrice and Genji die seemingly to Maria Ushiromiya who suspiciously shares a voice with Hanyuu while Natsuhi exits at the same time as Witch Satoko leaving Battler, Jessica, Maria and George alive in the same way Rika, Red Eyes Rika, Hanyuu and normal Satoko are still present in Gou) I would say she uses samples from Beatrice Rika and Looper Satoko(whom George Ushiromiya represents) to create Jessica and Witch Satoko within her own body during Mei.
Witch Satoko would loop into past Looper Satoko while Jessica would loop into Bernkastel setting up Gou.
In that case Higurashi Gou is the Legend of the Golden Witch and Beatrice Rika is watching from a safe distance both admitting to being behind everything and denying being behind everything.
Higurashi Mei would be Turn of the Golden Witch where she fully takes the credit before Bernkastel(having got in contact with her) convinces her to fight Featherine AKA Beatrice Castiglioni and deny herself of being Beatrice.
Mei would be followed by Banquet of the Golden Witch which would be followed by Alliance of the Golden Witch, End of the Golden Witch(where Beatrice Rika jumps into Jessica’s timeline) and Dawn of the Golden Witch(which gets Bernkastel/Erika Furudo booted out of Jessica’s host)
Higurashi Rei Manga would be Requiem of the Golden Witch followed by Twilight of the Golden Witch.
So… Alliance of the Golden Witch, End of the Golden Witch and Dawn of the Golden Witch are the finale of Higurashi along with Last Note of the Golden Witch.
