Postal Anime de Verano con Pistola de Agua

Dynamic vertical anime summer key visual illustration featuring [Kiyoka], a cheerful teenage girl in a sporty one-piece racing swimsuit, 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 lens flare sunlight from the upper left. Close-up low-angle wide-angle perspective: leaning forward toward the camera while aiming a large blue-and-yellow water gun directly forward, spraying water toward the viewer. She has a playful, energetic expression with one winking eye, one open bright blue eye, an open smiling mouth showing a small fang, wet skin, and dripping droplets. She has short wet dark navy-purple hair with messy strands, glowing blue highlights, pointed elf-like ears, small blue flower earrings, and a slim black choker. Her athletic racing swimsuit is white centered with dark navy side panels and a small black logo reading "[athleis]" on the chest. Vivid dynamic water splashes, floating translucent bubbles, cyan glow effects, and exactly 6 small luminous blue butterfly-like motifs drifting in the air. On the right side, vertical glowing white Japanese text in Mincho typeface reading "[暑中見舞い申し上げます]" with a soft cyan outer glow. Polished anime illustration style, saturated summer blues, crisp line art, glossy water caustics, and bokeh water droplets.
