I can still post the pic, but see no point since there was a pic of all the girls on the new chapter.
Girls who has yet to re-appear at all:
Swimming Girl Club
Shougi Girl
Girl who looked at the stars
Library Girl
Teacher
Karate Sister who became huge
Prolly missing a few, this off top of my head.
I can discard the Teacher and Karate Sister since they both left town.
Here is hoping it's not Library Girl or the one who looked at the stars, They were the most boring. Hoping it's the one who plays Shougi. After Track girl she is my favorite of the series. I really liked her character design.
