A medium shot from a side-angle portrays a cool, handsome young boy standing under a night sky. He has short, dark brown hair and striking light blue eyes, wearing a traditional Japanese yukata with a subtle pattern. He holds a handheld sparkler in his right hand, gripping the thin wire firmly, while his left hand is tucked casually into the pocket of his yukata, his expression composed and calm with a slight, confident smirk. The background is a deep midnight blue sky illuminated by the brilliant, explosive bursts of colorful fireworks, casting vibrant reflections on his face and clothing. The visual style is a high-quality anime illustration with a rich, contrasting color palette of dark indigo and vivid sparks. Dramatic lighting from the fireworks creates a luminous glow, with floating embers and a soft depth of field that emphasizes the character's cool demeanor amidst the festive atmosphere.
