習作：ブラックホールの空間の歪み

夏休み白昼の最新設備を有した伝統ある私立高校。地学準備室の天体観測機器置き場で、高橋製作所製P-2Z赤道儀と付属の小型屈折望遠鏡を整備する制服姿の一人の女子高生。彼女の目の前に突如芥子粒サイズのマイクロブラックホールが出現、重力で周辺数センチの空間を球状に近くほど強く歪ませている。驚きと、科学知識から来る興味と、縮退空間に飲み込まれるかもしれない恐怖との錯綜。思わず後退りする。 [Female] She is currently 18 years old. She has long, straight-cut black hair that reaches her waist; it is fine in texture and has a lustrous sheen, and she wears bangs. She is a 168cm-tall Japanese woman with a slender physique—rivaling that of a Hollywood actress—measuring B83/W50/H85. She wears triangular stainless steel wire earrings and sports crimson lipstick with natural-style makeup. [Dress uniform] Made from smooth, breathable, thin silk twill, this sleeve-less dress requires no lining and nothing underneath. It features a high, full-coverage back and wide straps, while the narrow, deep square neckline beautifully highlights the décolletage. Princess-seam paneling runs from the shoulders and bust through the waist to the hem, creating a snug-fit silhouette and an well above knee pencil skirt. A matching fabric belt with a square chrome buckle at front, cinches the waist. Each exact side seam is replaced by one narrow, exposed, two-way zipper running continuously from directly beneath the underarm to the hem. Each zipper is equipped with two sliders: the upper one positioned at the armpit and the lower one at the starting point of the side slit. The zipper is a fine-gauge dark-navy nylon coil zipper with small polished chrome pull tabs matching the belt buckle. It is functional rather than decorative and never moves onto the front or back panels. Their precise placement at the side edges offers several advantages: - To put it on or take it off, simply remove the belt, slide the lower zipper pull upwards to fully open the sides, put your arms through while inserting your torso from the side, put your head through, put it on, close the zipper, and fasten the belt again. This method is easier to manage than a back zipper and eliminates the need to lay the dress on the floor and step into it from above. - With no zippers on the front or back, the garment maintains a clean, simple aesthetic. Furthermore, the zippers are inconspicuous as they are positioned where the arms naturally hang. - Partially opening the zippers from the hem creates slits on both sides, allowing for smooth movement while walking, even with the skirt that fits tight around the hips. Opening them more creates a lively look, while opening them slightly creates a more modest look. - Even when the zippers are opened wide, the thighs remain largely concealed from the front and back—where they would be most visible—ensuring an elegant gait. The bold opening is visible only briefly from the side. - Unlike a single side slit, the skirt does not become lopsided or disheveled; opening the zippers symmetrically maintains the skirt's balance while walking. [Undergarments] Made of white chiffon. It consists solely of sewn-in long sleeves (with cuffs) and a detachable collar (without a bodice section); the collar is adorned with a deep crimson ribbon bow. No other undergarments are worn, preventing the silhouette from being spoiled by visible lines through the uniform. [Waist Belt] A belt made from the same fabric as the dress—featuring a square chrome buckle at the front center—is worn over the dress to accentuate the curve of the waist. Belt loops are provided at the front-left and front-right of the bodice, as well as at both ends of the back panel. [Footwear] Dark navy knee-high socks feature a small embroidered city crest on the upper outer side. The shoes are black stiletto-heeled loafers with thin soles and 9cm heels.
