Tableau des relations entre les personnages japonais (affiche)

Using REFERENCE_0 as the cast reference, transform the simple lineup into an ornate Japanese light-novel character relationship chart poster. Keep the same 10 named characters and reuse their existing portrait art as the base visuals, but redesign the layout into a polished infographic on a soft cream and pale-blue fantasy background with decorative borders, sparkles, roses, and a small European-style hotel building vignette in the upper left. Add a large Japanese title at the top, 「支配人はかりそめの顔」, with the subtitle 「キャラクター紹介＆相関図」, and place a dark badge in the upper right that says 「ネタバレ配慮版」. Put the heroine 一条 紬希 in the center as the main focus in a framed character card labeled 「主人公」, and place 秦野 啓司 in a large framed card on the right as the key counterpart. Arrange the remaining 8 characters around them in individual profile cards: 加賀坂 その葉, 川原 澪, 樫村, 紬希の母, ハルカ, 杏子, 美果, 桜子. Connect the characters with multiple colored arrows and relationship labels to visualize the network; include exactly 14 visible relationship labels: 「親友」, 「理解者」, 「本音を見抜く」, 「憧れ」, 「相談」, 「画策」, 「仲直り中」, 「直感的理解」, 「メンター」, 「実務支援」, 「保護者的存在」, 「後輩　ムードメーカー」, 「後輩　グループを支える」, 「後輩　明るさ・希望」. Also add the 8 central horizontal relationship callouts between 一条 紬希 and 秦野 啓司: 「偽溶み→公認」, 「ライバル」, 「秘密を共有」, 「対等な相棒」, 「気になる存在」, plus a pink central badge reading 「反発から信頼へ」, and 3 lower callouts: 「信頼」, 「協力を後押し」, 「二人の空気に気づく」. Include a gold-ribbon group label above the three lower girls that says 「ASTRALの仲間たち」. Add a bottom section with exactly 10 smaller summary cards, one for each character again, lined up across the width. On the far right, add 2 boxed sidebar sections titled 「作品のキーワード」 and 「関係の見どころ」; the first should contain 4 bullet items with icons, and the second should contain 4 bullet items with icons. Fill every card with dense Japanese profile text and role tags in a clean editorial style, as if for a promotional relationship guide included with a novel. Make the overall design elegant, readable, romantic-mystery themed, and magazine-quality.
