>>33602895Kiara had a pretty weak debut, and her choice of games are not very streamer friendly, but she's found her niche in hololive and focused on improving her strengths. She's also really good at putting herself out there, even if it's somewhat forceful at times. Kiara has goals that she's focused on achieving.
Ame on the other hand, she was the best of the myth girls at gaming, so she attracted a sizable portion of fans for that reason. She was also the most inventive and also the most willing to invest a fuckton of money into her streams, like commissioning 3d models, getting a whole ass studio to do 3d work, shit ain't cheap. However, her bread and butter content has gotten stale; you can only watch an anime girl get unnecesarily salty at games for so long, and it goes from amusing to concerning when you find out its actual salt and not played up for laughs, especially when it's directed towards senpai or her other myth members. Far as I know, Ame also doesn't have any real goals she's working towards now, there's nothing exciting to keep fans around.
In short, while the Stars drama has minor influence, the real reason Ame's numbers are down and Kiara's numbers are up is because Kiara has fresh shit happening while Ame's content is stagnating.
