Yua Taoka. Nickname: Yuachi. A high-energy, extroverted gyaru who expresses her emotions directly. She's a bit of an airhead but has a very caring and lovely personality. She absolutely adores Reina.

Reina Watase. Nickname: Renachi. A cool, mature-looking gyaru who seems unapproachable at first glance. While she appears rational and calm, she actually has a very kind and deeply affectionate inner self.

Kokona Yazawa. Nickname: Yazawa. Yua's childhood friend, a high-tension and super energetic "bomb" of a gyaru. A funny-type gyaru who always charges full speed toward anything fun.

Akane. Shion's older twin sister. Among this group of unique gyarus, she is relatively sane (?) and plays the straight man role, calling out the others' wild behavior.

Shion. Akane's younger twin sister. She usually carries a quiet atmosphere, but there's a gap in her personality where her word choices are surprisingly sharp and merciless. Loves gummy candy.
