>>24615059Mori dropped a lot of the fake kayfabe parts of being "Mori", but generally she's the same even if you go back and watch her older stuff, the "cutesy" stuff actually happened pretty infrequently, but it was very notable when it did happen so people remember that part of her more.
I agree that in terms in "personality" specifically, Gura changed more than Kiara has from debut, but the confidence, mental health and insecurity difference in Kiara is so drastic that I think it supersedes changes in personality traits. It's not just that Kiara is better at being Kiara, it's that Kiara is way, way, waaayyy better at being Kiara.
My two cents at least.
