Who are these bunny girls from Gurren Lagann referencing?
4 is Mahoro Ando from Mahoromatic
6, Anna Kurauchi (He is my Master) is the only prominent GAINAX character I know with that color hair and hairstyle
7 is Aki from Abenobashi
8 is Reiko Kashiwara from Gunbuster
10 ???
12 possibly the "Owner" from Ebichu or Yukino from His and Her Circumstances because she sometimes wears her hair that way
14 possibly Sakura Miyuki from Mahoromatic?


Most likely they're just random girls as there's really nothing that can accurately identify them like clothing or eye color.
