Azur Lane's Atago is depicted in a Gakuen Träumerei-inspired campus scene that blends naval elegance with student-life charm. The figure features Atago with flowing indigo hair tied with delicate ribbons and a composed, confident gaze. She wears a stylized school uniform: a deep navy blazer with gold piping over a crisp white blouse, a matching bow, and a pleated skirt that falls to her knees. Her stockings and shoes are polished, and a small naval cap rests at her side. The base hints at a classroom podium and reinforced deck-plate textures, with subtle weathering and enamel painting that highlights the sculpted lines. The overall pose suggests poised readiness, as if she is about to lead a drill or lecture.

Within Azur Lane's world, Atago is a veteran cruiser known for steadfast leadership and a loyal spirit. In the Gakuen Träumerei interpretation, she becomes a diligent student and mentor, guiding new ship girls through academic challenges and fleet drills with calm confidence. Her interactions reveal her protective nature and sense of humor, balancing strict discipline with warmth. She carries a sense of history and duty, often reflecting on past campaigns while encouraging teamwork and shared growth among her classmates. This narrative emphasizes Atago's dual role as an elder sister figure and a capable commander, ready to adapt to the joys and hurdles of school life.
