character: mio_\(pixai\). A cinematic 16:9 over-the-shoulder POV shot from behind the right shoulder of mio_\(pixai\), showing her small silhouette in the foreground as she walks into a vast, tall hall. Mio is captured in mid-startle, her hands slightly raised from her sides and her head tilted forward in recognition; she wears a navy blue sailor-style crop top, a black beret, and white gloves with black bows. In the distance, down the central aisle, a wide cream-linen banner hangs between two slender iron poles, featuring the text "HAPPY 4TH BIRTHDAY MIO" in deep cobalt-blue cursive with gold flourishes, backlit by a warm amber glow. Beneath the banner sits a cake table with a tall lavender-frosted triple-layer cake topped with a Moonglade Athenaeum fondant medallion, surrounded by ivory tapers and cobalt-blue sugar stars. The atmosphere is a painterly semi-realistic anime style, contrasting the warm amber light of the banner against the cool, dim dusk tones of the hall.
