Emma was a short girl, very similar to her mother, Karen Kurokawa, and also slightly resembling her older brother, Manjiro Sano. She had a rather feminine figure for her age. She had sandy blonde hair that she swept over her shoulder and golden eyes. She was most often seen wearing her school uniform, which consisted of a button-down shirt, a skirt, and a jacket that she tied around her waist. Emma exhibits a very childish behavior when around Ken Ryuguji, her longtime love interest. She will flirt with others to make him jealous, but quickly gives up when she realizes it's not working. She tries to act older than her years, but her childish nature prevails—she's devoted to her brother and follows his orders.

Hinata notes that Emma is a pure romantic at heart who wants her love to be reciprocated. Hina also notes that she is a very kind girl who cares for others, despite her attempts to remain calm and detached.
