카타나를 든 웅크린 메카 여고생

Vertical anime mecha-girl illustration on an isolated clean white background, framed by a thin orange sci-fi HUD border with clipped corners and small side tick marks. Exactly one teenage anime action mecha girl crouching in a low side-profile pose, leaning forward and looking downward. She has straight medium-length [brown] hair partially covering her face, with a flat opaque tan rectangular censor block covering the central face area. She wears a white sailor-style school blouse with rolled-up sleeves, a dark navy sailor collar and scarf, an orange necktie, and a short pleated dark gray skirt. Five major mechanical cybernetic elements: an oversized gray-and-orange cybernetic helmet and ear visor wrapping around the side and back of her head, two segmented robotic gauntlet hands, and two bulky gray, white, and orange mechanical leg and foot assemblies. She firmly grips one long vertical katana planted into the ground beside her left side; the katana features a white-and-brown diamond-pattern handle, mechanical tsuba guard, silver blade, and orange-and-gray tech fittings. Her left thigh is armored with a dark tech stocking or plate marked with white stenciled Japanese characters, and her exposed upper thigh has glossy anime highlights. Crisp cel-shaded line art, soft gradients, intricate hard-surface mecha panels, bright orange accents, and slight depth-of-field blur on the rear leg. Exactly two logos and one caption: a small orange logo reading "[MECHA GIRLS]" with a chibi mecha icon at the top-left, an orange circular tech emblem reading "[IONEN]" at the bottom-right, and tiny orange text reading "MECHA GIRL" at the bottom-center. Dynamic close crop, no extra characters, no background scenery.
