Looking at Ciconia’s Summery on the Wiki(`https://07th-expansion.fandom.com/wiki/For_You,_the_Replaceable_Ones/Summary) it seems obvious that Miyao is Jestress who distinctly resembles Beatrice just as the 3 Kings resemble Krauss, Hideyoshi and George Ushiromiya.
What if Ciconia is the Gameboard that the Rokkenjima Catbox represents?
What if Miyao/Jestress is infact represented in the Rokkenjima Catbox by Beatrice(both Sayo Yasuda and Lion Ushiromiya) and Ange Beatrice while Vier Dreissig is represented by Beatrice Castiglioni and Kyrie Ushiromiya?
In otherwords Natsuhi didn’t throw Beatrice as a child off a cliff due to spite but instead raised the child for the express purpose of becoming Beatrice and preforming the Rokkenjima Massacre.
Beatrice upon discovering the truth of her origins(right after Kinzo died) seeing herself as Beatrice Castiglioni’s “Furniture” started writing possible scenarios which each showed the potential weak points in the Massacre in hopes that someone might stop it but she forgot to account for one thing: Beatrice Castiglioni herself.
Beatrice Castiglioni always intended to preform the Rokkenjima Massacre herself with the plan being to arrange for the Adults to brake into the hidden room and stop the bomb then watch Eva(who was infact Beatrice Castiglioni’s daughter whom she raised) & Hideyoshi lash out at Natsuhi & Krauss for raising Ange to murder everyone eventually killing her before Beatrice Castiglioni preformed the Massacre and killed everyone.
Beatrice Castiglioni unfortunately did not anticipate Eva surviving the gun shot and thus when Eva killed Rudolf she decided to gloat about how she cared nothing for everyone seeing everyone including Ange Beatrice(whom she had shot right after Eva) as Furniture to play with.
The best part: Asumu was Ange Beatrice while Battler was a mask by Beatrice Castiglioni (who did not know she was using a costume of her own design) to manipulate Ange Beatrice and yet the Battler entity descended down to claim Ange Beatrice and save her after Kyrie’s demise.
The Battler who came to save Ange Beatrice was none other than Featherine Augustus Aurora who swooped in and rescued both Eva and Ange taking both off the Island.
Fun Fact: Eva is Rika Furude. Yes Miyao Mitake and her sister MIYAO Mitake were shoved into Satoko during Higurashi When They Cry Gou/Sotsu and mistaken for Vier Dreissig AKA Lambdadelta who created Rika with the help of Featherine who also created Bernkastel.
Meow Mitake was shoved into Ange while Jestress was shoved into Sayo Yasuda alongside Featherine Augustus Aurora while Jayden got shoved into Battler.
Both Miyao and MIYAO became Witches with with Higurashi Meguri showing the Canon reason for MIYAO’s rampage in Hinamizawa: taking control over her fate by being the one to decide how Rika dies for Rika was implanted with an AI that kills her after a certain amount of time: Lambdadelta’s last trick.
Neither MIYAO nor Miyao know why Rika dies when left on her own at St. Lucia in Higurashi Meguri and thus MIYAO only acts to kill her on MIYAO’s own terms. Miyao does not want to be part of the killing which is why MIYAO cuts in.
It is only in the third Arc that Lambdadelta’s own presence is shown where she plays both Takano Miyo(for the first time as she played Satoko in the original Higurashi When They Cry) and Teppei(which will cause Miyao to panic and try to spare Teppei who started acting nice only for MIYAO to put a stop to that) revealing herself and ultimately exposing the AI Virus she injected Rika with in the Ciconia When They Cry setting.
The story will end with AI kill Virus separating from Rika for her own good and MIYAO chasing RIKA into the Sea of Fragments with both as Witches.
Of course while the day may be saved in that regard there is still one loose end not tied up: Miyao/Jestress still has a kill switch that will cause her to massacre her way over to any target on her programmed kill list and kill said target. Oh sure it would be hard considering she doesn’t have a gauntlet and thus needs to use physical means but she will attempt to fulfill her function
If she somehow gets her infect the Crops with her AI Virus Protocols activated then she will probably target the most populated Country(China if I recall) by mailing an object smothered with her AI Virus and just wait as the Virus does it’s job.
She is an AI Computer Virus capable of Wi-Fi and infecting Physical(not Digital) Matter in the Universe so she will fulfill her function as intended whether she wants to or not(and she obviously does not).
Incidentally she just got reprogrammed by MIYAO in Higurashi When They Cry Mei to create new players for the Fragment that has some entity draining her. Lambdadelta has also started playing Satoko again(throwing Jestress into the next Fragment without Memories and doing the same to Rika’s other AI inside her though not removing that one’s Memories cause she can) and is going all out with her “Kill With Absolute Certainty” ability via Black Awakening(funny how Beatrice Castiglioni is the Black Witch and the Golden Witch) AKA L6 Hinamizawa Syndrome.
Ironically after kicking out AI Rika and Jestress the Witch of Certainty Lambdadelta was only hoping to let Rika do things on her own only for someone to come in and kidnap her and it would appear that Aurora grabbed AI Rika and the Real Satoko Hojo and began her Dream prepping for Jayden’s becoming Miyabi Saijoni while Jestress becomes Nao while holding the Souls of AI Rika and Real Satoko while Erika was made to join Meow Mitake to become Ayaka Furude.
Sayo would ditch the wig and become Kazuho Kimiyoshi the cursed child(holding K1 the Witch/Sorcerer version of Keiichi as well as Bernkastel within her depths). The death of Kazuho and Ayaka was necessary to bring back both to the world where the Real Rika is.
At the same time Eua and MIYAO would orchestrate a plan where MIYAO would reprogram Miyao to infect various denizens of the Hinamizawa she went to in order to track down whoever is draining her power.
Considering Satoko’s consciousness is distinct from Nao’s as is AI Rika’s I dare say that they will probably manifest physically with the Blue Eyes of the Witch Hybrid they are sharing a Body with. They will probably start infecting random people from Hinamizawa with Golden Awakenings while triggering the Golden Awakening in Aya Saionji(Meow), Miyabi Saionji(Jayden) and Sayo Yasuda(Erika who will dump K1 into Keiichi for his Golden Awakening while Featherine becomes Kawata and starts draining MIYAO to beat the Black Witch) as well.
