One of the best rules you can follow if you're a vtuber idol is always embrace the memes given to you. Suisei, Sora, Haachama, Miko, Pekora, Botan, Korone, Noel etc all did this to their success. Hell, Kanata probably pushed the 'Gorilla' meme harder than anyone.
Meanwhile, Calli, Kiara (and it seems continiously Flare) continue to be hardnoses. The problem is their ego is involved. They think they matter more than the audience and they don't. Being an idol means sacrifising yourself for the enjoyment of the audience. It's not about you making yourself successful and trying to brute force your own songs into success. That shit doesn't fly because people can smell the desperation. Calli's lucky her rap songs made an impact, because she would've floundered hard with her general attitude.
