Japansk Mecha-pigefigur-reklameplakat

Create a premium Japanese plastic model kit product-poster layout on a clean white studio background with subtle gray gradients and a glossy floor reflection. The main subject is a highly detailed anime mecha schoolgirl figure posed dynamically in the center-left, in a wide combat stance, holding a katana horizontally across the frame with one robotic hand gripping the hilt and the other making a peace sign near her face. Show every face clearly with natural, detailed facial features, short dark navy-blue hair in a tousled bob with small side strands, and gold horn-like mechanical hair ornaments. Her outfit is a fusion of a Japanese high school sailor uniform and hard-surface sci-fi armor: white armored torso with mechanical panel lines, a red sailor neckerchief, a pleated navy skirt, bulky white armored thighs and shins, red and blue accent parts, gold circular joint details, a dark blue waist ribbon or back cloth, and red mechanical backpack-like attachments at the hips and lower back. The katana has a dark blade and a blue-and-gold wrapped handle. Render the figure like a professionally photographed collectible model or action plastic kit, with sharp material definition, realistic molded plastic surfaces, slight satin sheen, and commercial product-shot lighting.

Design the page as a figure advertisement/spec sheet with exactly 1 large hero image and 5 smaller detail panels stacked vertically on the right. The 5 right-side panels must show: 1) close-up of the head and hair ornaments, 2) upper-body torso detail with sailor scarf and chest armor, 3) weapon and articulated hand close-up with the sword near the face, 4) waist attachment and skirt/hip armor detail, 5) leg detail close-up showing joints and armor construction. Include thin blue divider accents around the right-side panel area.

At the top left, place a large Japanese title in bold serif-like characters reading "女子甲生", with the middle character in dark red and the others in dark navy. Beneath it, add a smaller Japanese subtitle line: "— メカ × 少女 × 青春 —". On the upper right, place a sleek logo and brand name reading "{argument name="brand name" default="TENNEN"}" with small Japanese text beneath it. Add a vertical Japanese slogan block on the left side of the hero figure reading "鋼に咲く、乙女の意志。" with the middle phrase in red. Add Japanese captions beneath each of the 5 right-side detail panels: "表情造形", "上半身ディテール", "武装・可動手", "腰部アタッチメント", "脚部ディテール". In the lower left, include a boxed scale label reading "{argument name="scale label" default="1/12 SCALE"}" and nearby English product text reading "FULL ACTION PLASTIC MODEL KIT". Add two small bullet lines in Japanese beneath that: "◆ 塗装済み髪パーツ付属" and "◆ マーキングデカール付属". Across the bottom, add a dark navy footer band with the brand logo and "{argument name="footer brand" default="TENNEN"}" centered, plus small Japanese text below.

Use a polished modern hobby-brand aesthetic, Japanese mecha-girl collectible packaging design, minimal white negative space, crisp typography, balanced editorial layout, and realistic studio-photo rendering of a non-existent original figure. Color palette: white, navy blue, dark blue, red, gray, black, and metallic gold. Aspect ratio 3:4.
