Sopia is a short girl with a cute appearance. She has neck-length purple hair with distinctive yellow underlayer, and a unique "starlight ahoge''" on the top of her head which somewhat resembles a question mark.

Her standard outfit is space-themed, resembling the top half of an astronaut's space suit paired with black shorts and purple gloves. The suit is edged with gold, lined with cyan quilting, and bright orbs on the sleeves. It is decorated with colorful transfers depicting rocketships, planets, and other space and science themed motifs. She wears white shoes with aquamarine detailing, and carries a ray gun in a holster attached to her leg.
