I had the most silliest idea come to mind earlier today thanks to me deciding to shuffle my OFA playlist while I was doing my chores. I ended up coming up with a list of the top 12 artists in my AU (both including NSR and OFA) and to my utter shock and hilarious reaction, the top 3 artist were all digital/ai beings (1 being NSR and the other 2 being OFA artists)
Top 3 was CAL aka a sentient tablet created by Orion and also an utter menace to society coming in 3rd place, Mimi aka a literal parody of Sayu that's a bit younger than her and controlled by literal middle schoolers under the watchful eye of their manager/guardian being in second place, and finally in first place the Beloved Idol of Vinyl City herself aka Rosie, who holds the title of the most popular artist via her digital form being projected by a mix of technology and magic while her real form controls it behind the scenes. It was hilarious because I was going to make it canon that these bbys were the top 3 artists and my playlist helped me confirmed this idea-
Anyway a very horrible idea for an au came to my mind and it could possibly take place in any timeline/au since it involves these 3 taking over Vinyl City when everyone leasts suspects it, and it's mainly because since Rosie is the youngest daughter of Tatiana and Olive, Mimi is like a little sister to Sayu, and CAL is Orion's creation. Everyone gets a rude awakening when they get suddenly get kicked out of Vinyl City because a new era of the digital age has arrived and Rosie rules from the NSR Tower combined with her castle in her online district of Rosetta, while Mimi has control of the NSR branch and rules in Akusuka and CAL has the OFA branch and rules from his district of Cyberspace. Now the rest of the OFA cast along with the OG cast need to work together to retake Vinyl City and talk some sense into the Digital Tripod (That's what Imma start calling them) since they just kids and they're taking things a bit to far-
The whole thing was Rosie's idea since she isn't usually involved/included in the affairs of NSR since her oldest sister Titanium was being a bit overprotective of her, and she noticed how her mother Tatiana was strict on music genres during her rule and the public's opinion of digital/ai beings having sentience and the negative backlash from it. Rosie did have good intentions to bring change but when she tried to bring it up she ended up getting dismissed and receiving promises from her sister Titanium that "Change will come, but we need to focus on other important matters little sister."
Cue Rosie conspiring with Mimi and CAL to do something and then the next day they launch a full fledged revolution with Rosie's digital mermaid, fairies, and other magical beings army coming in at full force and kicking Titanium out of the NSR Tower before kicking the current artists and the og artists out of Vinyl City. (Nobody got hurt thankfully but it did catch the entirety of the city off guard-) Now that the Digital Tripod have gained full control of Vinyl City with Rosie being at the top and looking down at the music capitol from her throne. Mimi and her crew are just vibing while they share their space with the fans while throwing parties at the Kura Kura stream Hub, and CAL continues to be even more of a menace to society while also finding and leaking NSR and OFA's well kept secrets to the public.
While this is all happening Titanium blames herself for the Digital Tripod putting her and everyone else in their current situation, and believes that she should've done something sooner to prevent it. She does talk with her sister Sonya and then they talk with Tatiana and Olive before they all agree that they need to first take back Vinyl City in order to get to Rosie and talk things out with her. Sayu and her crew also agree to tag along and also bring Sylvie so they can get to Mimi and talk with her crew and the crew's manager/guardian who's also dealing with stress from taking care of her young nieces and nephew after their parents had tragically passed away in an accident and also having to fight for custody for all of them. Orion would need to enlist the help of her father Kliff since she has no idea why CAL decided to go along with Rosie's plan and find a way to get to him without using the option to shut him down. I don't know which of the other artists would also join the 3 groups to confront CAL, Mimi, and Rosie but I think they would want to help in some way.
This is all I have so far, and maybe I might go into it more but this was all just an idea I had come to me. I hope you enjoy :D
That Tatiana magazine cover was right! "Sayu: The future of music?"
Also, I laughed out loud at you calling them the "Digital Tripod" for some reason lol! It was not a nickname I expected but it was a good one nonetheless!
For some reason, I can also see the Digital Tripod as just having gone into everyone's account and just locked everyone's emails and stuff. I know you said everyone was kicked out physically, but these being youngsters all in the digital space/mindset just makes me think of an IT person changing passwords to piss off non-tech literate people lol.
Plus the idea that all of the Digital Tripod are just doing this for shits and giggles is funny as hell. I know Rosie wants things to change, but the others are a lot more selfish from what I read. With Mimi and Crew just partying and having fun while CAL is literally revealing secrets of the company (which I am surprised Rosie or the others aren't trying to stop).
It really does just feel like a bunch of kids that let the power go to their heads in like 3 seconds of getting it lol.
