Love Live! Sunshine!! has been a wellspring of context clues to (maybe bordering on wacky) fan theories. You combine fanatical followers with use of real locations and you can't put a shot of AKIHABARA UDX into the anime without someone suggesting that it signifies that A-RISE's old school has been shut down. The latest (probably largely tongue-in-cheek) theory is the suggestion that men are extinct in the anime.
Now, male characters have always been rarely seen in Love Live! anime, especially male characters not voiced by Sora Tokui, but when they remove the bathrooms?!

Yeah, you can probably thinks of some alternate explanations, but it's still a fun detail.
