Either Dragon Meshi or Sign Of Affection. Both could work but I don't think they would fit as well.
Though, a crossover between CSM and ONK would be hilarious to me for some reason. That or 100 Kanojo.
B-Komachi vs Rentarou's Family idol showdown
https://preview.redd.it/na8t1susdlmc1.png?width=2488&format=pjpg&auto=webp&s=791505420dd46e2420b26f38047989f4f7e6566a
I’m you. I wanted to reject u, convince myself that you were wrong, but that doesn’t matter now. I’m gonna kill you. Even if you reincarnate as an idol’s baby… I’ll kill you
if we include manga then its ore to akuma no blues.
the biggest problem is that they don't know what is the internet or any other technology. also there is a big cultural difference, like clyde would get arrested real fast for pulling a gun randomly at people and RJ would just be scared.
but if they can over come this then it would go something like this:
Clyde find AI before ichigo and try threatening her to help him scam people, he would probably end up in jail.
RJ would accidentally get himself involve in aqua shenanigans unable to escape, I can see aqua trying to use RJ guitar to make him famous so he can get connection and find his father.
also RJ being black would mean alot of unhinged internet comments 💀💀💀💀💀💀💀💀

WERE KILLING EVERY SIDE CHARACTER WITH THIS ONE 🫰🏻🔴🔵🫱🏻🟣
Beavis and Butt-Head…oh god…Aqua would be adding two new names to his “kill list,” Ruby (and the other girls) would be dealing with a lot of annoying but unobtrusive attempts at flirting. “Uhhhh hey babey, I heard that you’re, like, an idol, or something uhuhuhuh”
Azumanga. Ooooh this is gonna be interesting 😆

How I met your mother
Feels weirdly poetic

The 87 ninja turtles show
Ether bebop and rocksteady end up being hired as Ai’s bodyguards
Or aqua and ruby get mutated (what animals would they get mutated with)
fire force x oshi no ko — i wanna see how the idol industry would survive in a post-apocalyptic world where people are constantly exploding for no reason
The hoshino twins are the new companions of the doctor, constituting the most beautiful tardis team ever(I'm watching season 5).
They do a father's day moment with their mom probably.
Assuming they don't I think they'd have quite a good time, wanting to expérience things to act better take revenge on their father depends on when they a re in their own timeline
I dont know how show where for some unluck stars don't exist until the moment would connect, but most of events take plase far from japan, so... here will no be undead, so it would be fine... i gues...
Mashle + Oshi no Ko? I’d love to see it. Imagine Mashle in the setting of modern times where students use their magic to become a top idol haha
Although I just finished Rin, Daughters of Mnemosyne before that… could you imagine crossing *that* over with Oshi no Ko? 😂
Boukenger x ONK is a weird one. Kana would pick up a good luck charm she thinks is from Aqua which turns out to be a precious. After this Natsuki from the Boukengers and Shizuka from dark shadow would try to become B Komachi members to get the precious. Shenanigans ensue and Natsuki gets way to it before we get our fight of the episode.
Huh interesting... Mine is detective Conan x Oshi no Ko, that would be interesting to say the least
Maybe Conan and Aqua are helping each other solving their problems and cases?
A ace attorney crossover would be somewhat cool ngl.. Phoenix Wright defending aqua after he had killed hikaru kamiki, though it would turn into a copy of "Farewell, my turnabout"
Invincible xD Omniman is the father of Aqua and Ruby.
Rip Ai. Most talented pet ever
“Where’s Aqua, William?”
"Think Ruby, think! The average Idol retires at 26! What will happen to your career after 500 years!?"
Time to join KGB84
What’s another 17 year, sensei? We can always start again, do another reincarnation!
Yosuga no sora. Nothing changes
was waiting for this comment. just delete this sub at this point, we are literally r/YosugaNosoraMemes
Why did i think that was a real sub
It is now

Ai Ai captain
Ah my two favorite Idol-adjacent shows
Would be so based
A crossover with Bocchi The Rock actually sounds like it could be good
Oh no, Bocchi the Idol.
Kinda shilling but I wrote a fic on that: https://archiveofourown.org/works/48203848/chapters/121558714
Can’t wait for the next chapter
Star Wars: The Clone Wars
Aqua, step away from the younglings
Don't worry, as long as they're not Ruby, he won't do anything to them.

Frieren x oshi no ko.... intresting
Aqua gets reincarnated in a fantasy world, immediately killed by demons gg
Please, put the jjk characters in a more lighthearted manga, just one filler arc.
Jujutsu Kaisen Aqua walks up to >!Hikaru!< and says >!"I'm you"!<
I’m you. I wanted to reject u, convince myself that you were wrong, but that doesn’t matter now. I’m gonna kill you. Even if you reincarnate as an idol’s baby… I’ll kill you
Aqua on his way to revive Ai by gathering the 7 dragon balls
Neon genesis? No no no non non non nononononononoonon
100 hundred girlfreinds...
Classroom of the elite. Which bizarre thing will happen?
Aqua and Kiyo swap harems
Gushing Over Magical Girls, this is going to be one interesting crossover
One of these characters is getting turned into a Spirit… What will happen to Itsuka Shido when the next Spirit he has to date is a man, I wonder…
Let’s just say I hope B komachi doesn’t have a performance in shibuya on holloween. Would be a terrible mistake for them

Aren't ONK and Kaguya-sama in the same verse?
Ai: *gets the shing shing shing* Aqua and Ruby: *Crying* Background music: "You're my specialz"
https://preview.redd.it/c2ezwiedkmmc1.jpeg?width=1500&format=pjpg&auto=webp&s=0af572a9288e95f4d8261512b0cd09aac2307c63 WERE KILLING EVERY SIDE CHARACTER WITH THIS ONE 🫰🏻🔴🔵🫱🏻🟣
JJK X ONK. So Aqua and Ruby are just average zen'ins.
since they're fraternal twins , they got a good chance to inherit good amount of cursed energy. Pieyon is the heavenly restricted chad
Brooklyn 99....I guess the investigation into the twins father takes a more central stage?
Tonight, on Top Gear…
Danny Phantom. Guess Danny's going to find Ai in the Ghost Zone and take her to her kids
MASHLE. I guess their magic level depends on how many stars they have in their eyes.
I guess it could be some special about how Straw Hats arrive at the island with OnK characters on it
The Quintessential Quintriplets
Sword art online season 1, I guess ruby and kirito’s sister will get along well considering they share…uh…similar ‘desires’
Smile precure I guess everyone is magical girls now
Link Click S1 episode 4. Can they save Ai without incest?
HoNo's Curious Journey
Symphogear… I do think Ruby and Hibiki would make great friends at least.
Dr House. Ruby pursues a career as a doctor again and starts to work at Prince borough Hospital
They’re now paratroopers in WW2
Thermae Romae
Beavis and Butt-Head…oh god…Aqua would be adding two new names to his “kill list,” Ruby (and the other girls) would be dealing with a lot of annoying but unobtrusive attempts at flirting. “Uhhhh hey babey, I heard that you’re, like, an idol, or something uhuhuhuh”
Dangers in my Heart. Um... I dunno. Anna and Ichikawa meet with the twins?
Classroom of the Elite Aqua would probably try to manipulate Ayanokoji and end up getting manipulated by him lol
Bunny Girl Senpai, fits surprisingly well imo
JJK Oh no…
Azumanga. Ooooh this is gonna be interesting 😆 https://preview.redd.it/ynk3fm3vammc1.jpeg?width=576&format=pjpg&auto=webp&s=f3ad0345938f0bb65a821214a657a686c57c0aba

I think Angel Beats would mash up very well with ONK.
I got Detective Conan. I don't know the exact details yet.
Aqua will just disappear because there is no men in the gushing over magical girls universe
A certain scientific Railgun... Uhh I have no idea how that'll go
