Chibi Yonkoma Rainy Sports Day Manga

Vertical Japanese 4-panel manga comic strip (yonkoma), full color, 9:16 ratio, with a white outer margin and thick black borders dividing four equal stacked horizontal panels. High-energy, glossy digital webcomic style with expressive chibi art, bold outlines, and speed lines. Main character: A cute chibi elementary school [purple-haired girl] with long wavy lavender-purple hair, pale skin, round gray eyes that become sparkling star eyes when excited, rosy cheeks, wearing a pale pink short-sleeve buttoned blouse, light beige skirt, white socks, and simple shoes. Header: At the very top above the panels, a bold title headline reading: "[雨が空ごとプールに変わっても、楽しみは10倍に跳ね上がる！]". Panel 1: School sports day field under gathering stormy clouds. The girl stands excitedly in the center, smiling with clenched fists and sparkles. In the background: school building, international flag bunting, tents, and a floral arch labeled "運動会". On the right, a vertical speech bubble reading: "今日は運動会！". Panel 2: Indoor school hallway. A gray wall speaker on the left with a taped paper notice below it reading "雨で延期". On the right, a dramatic close-up of the girl shocked, sweat drop on her face, mouth agape, fist clenched, with radiating manga shock lines and a speech bubble reading: "延期!?". Panel 3: Heavy torrential rain and lightning flooding the sports ground into a shallow pond. In the foreground, the girl looks amazed with star-shaped eyes, holding a spiral calendar marked "運動会（新しい日）" with a large red circled "7" and "日後！" underneath. Manga sound effects: blue "ザーッ" for rain on the left, orange "ゴロゴロ" for thunder on top right. Vertical speech bubble reading: "あと7日!?". Panel 4: Extreme close-up of the girl's ecstatic face with sparkling star eyes, wide open happy smile, clenched fists, against a hot pink and red radial burst background with yellow sparkles. A jagged speech bubble on the left reading "100倍!!" in red and "楽しみ" in black.
