Atsuko Katagiri is a member of AKB0048 who has mysteriously disapeared. On Akibastar, She is known as Atsuko Maeda the 13th (前田 敦子) (also known as Acchan (あっちゃん).
Acchan has short, purple hair that slightly fades into purple-magenta and reddish brown eyes. She wore a small red-black ribbon in her hair when singing Aitakatta. She has a heart-shaped lining on her hair and eyes.
Acchan was shy and reserved. But when she steps onto the stage, the Kiraras all flocked to her in a glowing cloud, giving her some sort of confidence. It was like as if she was wearing a 'Dress of Light'. Acchan was also best friends with Tsubasa. Acchan told Tsubasa that she performed as a member of AKB0048 because she wanted to see the audience.
