Daia has a vibrant and whimsical appearance that reflects her origin as a virtual idol. She has light blue eyes with a distinct rainbow pattern within them, emphasizing her digital nature and cheerful aura. Her long pale blonde hair is styled into lightly curled pigtails, accented with streaks of pink and light blue. On each side of her head, a straightened light blue strand curls upward, adding a playful detail to her silhouette.

A braid wraps around her head, accompanied by a short pink cowlick, and her straight-cut bangs are accented with alternating pink and blue locks. Her forelocks mirror this pattern, appearing straight with curled tips, also in pink and blue hues, further enhancing her colorful and digitally stylized look.

During her transformation into Another Daia, her design undergoes a notable shift. Her skin tone becomes lightly tanned, and both her hair and eyes change to dark blue. The rainbow in her eyes also adjusts to purple, light blue, and pastel pink to match her new aesthetic. Her hair features indigo and purple streaks, reflecting the cooler, more intense tone of her altered image.

Following her return to normal, Daia appears in a smaller, chibi-like form, a result of system damage she sustained. Despite the size reduction, her essential features remain recognizable, preserving her core design elements.

Daia is a bright, cheerful, and energetic virtual idol who exudes positivity and enthusiasm. She is highly supportive of others, often encouraging her friends and spreading joy through her performances. Her upbeat nature and affectionate personality make her beloved by those around her.

However, during her transformation into Another Daia, her personality undergoes a notable shift. She becomes mischievous, more unruly, and somewhat mellow in contrast to her usual exuberance. This altered version of Daia also adopts a distinct accent and a more laid-back speech pattern, further distinguishing her from her original self. Despite this change, remnants of her charm and affection remain, showing that her core kindness is never fully lost.
