Rainy Sports Day Chibi Manga

Goal: Create a vertical Japanese 4-panel manga comic about a cute chibi girl becoming even more excited when a rainy sports day is postponed.

Canvas: Tall vertical comic page in full color, approximately 9:16, with a white outer margin and thick black panel borders. Use exactly 4 stacked horizontal panels of equal width, manga-style composition, energetic expressions, glossy digital coloring, bold outlines, dramatic speed lines, sparkles, and sound effects.

Main character: A single chibi elementary-school girl named [character name]. She has long wavy lavender-purple hair, pale skin, round gray eyes that turn into sparkling star eyes when excited, rosy cheeks, and a small open mouth. She wears a pale pink short-sleeve blouse with buttons, a light beige skirt, white socks, and simple shoes. Her pose is usually fists clenched near her chest in excitement or surprise.

Panel 1: School sports day setup under stormy clouds. Show the girl standing large in the center of a school athletic field, smiling with clenched fists and sparkles around her. Background includes a school building, Japanese flag, strings of international flags, a clock, a flower-decorated sports day arch labeled 「運動会」, tents, cones, bags, and lunch boxes. Add a large vertical speech bubble on the right with 「今日は運動会！」. At the very top outside or above the first panel, add the headline: [headline text].

Panel 2: Indoor announcement scene. Show a wall-mounted gray loudspeaker on the left, a taped white notice below it reading 「雨で延期」, and the girl on the right in close-up looking shocked with a sweat drop, clenched fist, and wide open mouth. Add a speech bubble on the right reading 「延期!?」. Use beige indoor wall tones and manga burst lines radiating from her face.

Panel 3: Torrential rain on the sports field. Show the athletic field transformed into a shallow flooded pool under heavy rain, lightning, dark storm clouds, and dramatic water splashes. The girl stands in the foreground with star-shaped eyes and an amazed open mouth, holding a spiral-bound calendar that reads 「運動会（新しい日）」 with a large red circled 「7」 and 「日後！」 underneath. Add two sound effects: blue 「ザーッ」 for heavy rain on the left and orange 「ゴロゴロ」 for thunder on the upper right. Add a vertical speech bubble on the right reading 「あと7日!?」.

Panel 4: Extreme close-up celebration. Fill the panel with the girl's happy face, sparkling star eyes, open smiling mouth, and clenched fists. Use a hot pink and red radial burst background filled with yellow sparkles. Add one jagged speech bubble on the left containing 「100倍!!」 in red and 「楽しみ」 in black, meaning the excitement is multiplied.

Text count and placement: Include exactly 1 headline, exactly 4 comic panels, exactly 4 speech bubbles, exactly 1 taped notice, exactly 1 calendar page, exactly 2 manga sound effects, and exactly 1 sports day arch label. Preserve all Japanese text exactly as written. Avoid adding extra dialogue, captions, logos, watermarks, or additional characters.

Visual style: Cute Japanese chibi manga, bright saturated colors, clean black line art, expressive faces, playful dramatic exaggeration, polished webcomic look, high readability of all Japanese text.
