>>1810106It's probably because the two societies in question define spaces differently, the Japanese are overcrowded but deliberately style their social mores to cope with it, meanwhile primarily white European nations do not and it would take less crowding and/or cultural conflict to bring it to a later phase of social collapse. It wouldn't be crowding itself that's affecting her, but the behavior of the people around her. Or, from a society still in the "equilibrium" phase to one in the "die" phase.
Anyway, just an idea. I hope that Kiara accepts the glory that is living rent free in the heads of your haters, she's the Trump of Holos and didn't expect to be, but it's a powerful social position if used correctly. She's not my favorite, but I want to see her get her cheese all the same. Often she acts as a catalyst for the others and EN would be less interesting without her. She needs to accept she's not a perfect seiso idol and embrace her Coco-ness.
