Watercolor Manga Locked Room Page

Goal: Create a watercolor manga page in a vertical comic layout about three anime girls trapped in a gloomy closed room, with Japanese speech text.

Canvas: Portrait page, approximately 2:3 aspect ratio, off-white paper texture, hand-painted watercolor and ink line art, soft washes, visible panel borders, no digital UI, no watermark.

Layout: Use exactly 4 comic panels: (1) top-left small panel, (2) top-right small panel, (3) one large central panel spanning the width, and (4) a narrow bottom reaction strip. Keep the page reading like a Japanese manga, with vertical speech balloons.

Characters: Show exactly 3 girls. Girl A is a confident purple-haired girl with long curled hair, a side braid, green eyes, cat-ear-like black silhouette behind her head, wearing a shiny gold sleeveless turtleneck; she looks angry and sweaty in the top-left panel and appears again as an intense close-up in the bottom strip. Girl B is a cheerful blonde bob-haired girl with purple eyes, wearing a red frilled coat and a dark green scarf; she raises one fist triumphantly in the top-right panel. Girl C is a quiet black-haired girl with very long straight hair and red eyes, wearing a loose green dress; she sits barefoot on the floor in the central panel, knees bent, one hand near her lips, looking thoughtful and worried.

Panel details: Top-left panel has a dark bluish background and Girl A speaking with frustration. Top-right panel has a bright yellow starburst background with sparkles, Girl B smiling confidently, and a red Japanese sound effect near the top. The large middle panel shows Girl C seated in a dim, concrete or stone-walled room with a vertical metal pipe on the left, cold blue-gray shadows, and a small bright window or opening at the right casting pale light. The bottom strip shows only Girl A’s narrowed green eyes and purple hair against a red background, emphasizing suspicion and irritation.

Text content: Include exactly 5 vertical Japanese speech balloons and 1 red sound effect. Top-left panel has two speech balloons: もう一ドヤって場合じゃないよ！ and こんな不気味な所に閉じ込められて……入り口、塞がってる!!. Top-right panel has one speech balloon: わははっ！ほら、入れるって言ったっしょ！さあ、手がかりを探そう！. Middle panel has one speech balloon: 脱出も大事だけど…それより犯人、まだいるかもよ？. Bottom strip has one speech balloon: ったく……いっつも後先考えないんだから……. Add the red sound effect 「ドヤ!」 in the top-right panel.

Visual style: Delicate shoujo manga faces, expressive eyes, thin ink outlines, watercolor gradients, slightly uneven hand-painted panel edges, soft paper grain, dramatic color contrast between the cheerful yellow top-right panel, cold blue-gray central room, and red bottom reaction strip.

Constraints: Count and show exactly 4 panels, exactly 3 recurring characters, exactly 5 speech balloons, and exactly 1 sound effect. Keep all dialogue vertical Japanese text, but do not add extra captions or additional text.
