If you like other idol franchises, tell me about your best girls/compare them to your favorites from Love Live! It's fun to see if you have a type.
(Edit: Did some research and added some more idols to increase the sample size, because this is super scientific)

Love Live
Muse: Umi, Rin, Nico, Hanayo
Aqours: Dia, Yoshiko, Hanamaru, You (honestly I can never decide on a 4th favorite but I'm feeling You right now)
N girls: Tsurugi, Mutsuki, Sakuya, Rika


Idolmaster
765: Chihaya, Ritsuko, Makoto, Azusa
Million Live: Shizuka, Julia, Mizuki, Sayoko (honorable mentions because there are too many: Subaru, Noriko, Tsumugi)
This is where Cinderella Girls would go if I actually liked any of them enough to pick favorites lmao
SideM: Rei, Jun, Shiki, Kaoru (THEY ALL LOOK THE SAME I'M SO DISAPPOINTED IN MYSELF)

Bandori: Tomoe, Sayo, Maya, Moca

Enstars: Keito, Souma, Tsumugi, Adonis (I LITERALLY KNOW NOTHING ABOUT ENSTARS EXCEPT WHAT I GOT FROM SKIMMING THE WIKI I'M SORRY but I think my first instincts here just reinforce how repetitive I am l o l)
After some scrutiny I realized with some amount of shame that I can categorize all of these characters with the following venn diagram. I am not proud. (I have no idea why there are enough characters with short grey hair to allow me to put them all in their own special box but that's just how it is now)

Also I can dump them all into 4 categories, with serious bitch being the largest because I too am a serious bitch so it's #relatable

As far as image colors go, 11 of these characters have blue as their color (or at least are represented with blue frequently enough for me to count them), making up the majority of the image colors. The rest of them are kind of a jumble, but there's a lot of grey, and pink/red make enough appearances for me to consider them significant.
FINALLY, if we pick characters with black hair, the Serious Bitch personality, and blue as an image color, we end up with this fun bunch that makes up 25% of this godforesaken list. (I'm sure they're very interesting at parties) (if they even went to parties)

In conclusion I like a Very Specific type of character and I'm very predictable about it please save me
