MottoI've been learning the language of flowers lately.

A mysterious member of the Arius Squad who always wears a gas mask. Atsuko's mask isn't necessarily meant for disguise but rather a gas mask she wears for protection and safety. The squad leader, Saori, calls her Hime. Very little is known of who she is.
