I love LLSIF.
My girls are
1. Hanayo + Eli
2. Umi
3. Kotori + Maki
4. Nozomi + Honoka + Rin
5. Nico
I don't have a hated "worst girl"; I like them all and I love any cards I get, even weird initial cards (lol hanayo and big booty eli). I am not a picky player. Even though 1 SR pulls ARE annoying, I just move on and keep playing.
