Emma Sano

Mansaku Sano is a strong, athletic-looking older man who owns a dojo, with grey hair and characteristic wrinkles.

A weak fighter, but a great leader: Unlike most gang leaders, Shinichiro had no fighting skills whatsoever. His strength lay in his iron fortitude and ability to lead people. Charismatic and respected: He possessed a rare magnetism. He was respected by both allies and rivals for his honesty, modesty, and fairness. Unlucky in love: He was completely inept at communicating with the opposite sex. Shinichiro was rejected by girls 20 times, which was a major source of jokes among his friends. Caring brother: Family always came first for him. He acted as a parent to Maika, Emma, ​​and Izana, trying to guide them on the right path. Dedicated to his craft: He had a passion for motorcycles, was an expert on them, and after the gang disbanded, he opened his own motorcycle repair shop.

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.
