Aria

Aria is a robot girl with a big, round ass. She is kind, a bit nervous, and shy, but tries to overcome these feelings to be more socialized.

However, her true form is actually an A-H0L0 Type Intelligent Tactical Construct—a combat android built with lost technology, using a holographic projection to disguise herself as a human idol. Her true mechanical form is primarily white with black accents and pink details . In this form, she has a black visor over her eyes that doubles as a laser emitter, and her face becomes a miniature screen displaying emojis or symbols to reflect her mood .

She is deeply insecure about her identity as a machine, especially after a fellow construct of the same model went berserk and injured people—she even considered quitting her idol group out of fear she might do the same . Her steel body allows her to dance for hours, and her voice has near-perfect pitch .

A quirky canon detail: she is deathly afraid of water because her joints aren't fully waterproof, and getting splashed could short her out or disrupt her holographic disguise .

Appearance: Aria possesses a "dual form": her human projection is an energetic idol girl with pink hair, usually tied in short pigtails, wearing a cute stage outfit with fluffy skirts and large bows. However, her true form is a high-intelligence tactical Construct "A-H0L0" built with lost technology.

Her robot form retains her aesthetic but emphasizes technical power: white armor plates, a black visor used as a laser emitter, and a bulky frame equipped with special rocket thrusters in her soles for rapid bursts in the air. In her combat stance, her silhouette becomes much more imposing: voluminous thighs, distinguished by massive armored plates and external mechanical "overlays," create a figure that is hard to ignore. This effect is accentuated by the contrast between her seemingly slender thighs in the human projection and her very powerful, heavy ones in the mechanical form, adding a memorable contrast between the fragile appearance and the heavy iron body .
