A high-quality anime illustration featuring a medium shot of a unique hourglass centered in the frame, designed with a ramune soda motif. The hourglass is crafted from clear, polished glass with a nostalgic ramune bottle shape for the top bulb and a rounded base, held together by a decorative white plastic ring and a vintage-style metal frame. Instead of sand, the interior is filled with translucent, sparkling pale-blue liquid and tiny, effervescent bubbles that slowly trickle from the top chamber to the bottom. A small, signature glass marble is trapped in the neck of the hourglass, mimicking the seal of a ramune bottle. The background is a soft, minimalist gradient of summer sky blue and white, creating a clean and airy atmosphere. The lighting is bright and luminous, with caustic light reflections dancing through the blue liquid and sharp, glittering highlights on the glass surfaces, evoking a refreshing and nostalgic summer mood.
