According to what I read the other girls are original characters named (茶子) Chako? and (黒子) Kuroko. Chako finds Aya to be cool and Kuroko is enamored with Momiji.
he names for the OCs seems to be provisiory. They refer to their hair color (Note: "茶" means "Light Brown" in this case). Furthermore, they are refered as sisters.
