Anime Summer Water Gun Postcard

Create a dynamic vertical anime summer illustration featuring {argument name="character name" default="Kiyoka"}, a cheerful teenage girl in a sporty one-piece racing swimsuit, fully clothed and non-suggestive. She is at a tropical swimming pool or beachside water park under an intense blue sky, with palm trees, sparkling ocean-blue water, and strong sunlight flaring from the upper left. The camera is close and low with a dramatic wide-angle perspective: she leans toward the viewer while aiming a large blue-and-yellow water gun directly at the camera, water spraying from the nozzle. Her expression is playful and energetic, with one eye winking, one bright blue eye open, an open smiling mouth with a small fang-like tooth, and wet skin and hair covered in droplets. She has short dark navy-purple wet hair with messy strands, glowing blue highlights, pointed elf-like ears, small blue flower earrings, and a slim black choker. Her swimsuit is white in the center with dark navy side panels and a small black athletic-style logo reading {argument name="swimsuit logo" default="athleis"} on the chest. Add vivid water splashes, floating bubbles, cyan glow effects, and exactly 6 small luminous blue butterfly or flower-like motifs around her and the water. Include vertical glowing Japanese text on the right side reading {argument name="vertical Japanese text" default="暑中見舞い申し上げます"}, set in large white Mincho-style characters with a soft cyan outer glow. Use highly polished anime key visual rendering, saturated blues, crisp linework, glossy water reflections, cinematic lighting, bokeh droplets, and a festive midsummer postcard atmosphere. Keep the composition portrait-oriented, action-packed, bright, refreshing, and safe-for-work.
