She wears a red-colored, short bolero-style jacket that reveals a lemon tattoo in her midsection. Honey Lemon's appearance is meant to match her personality: She originally had black hair, but was dyed blonde, and her eyes were originally brown then later shown as blue (likely through the use of contact lenses). She is also scripted as a sexy troublemaker, and seemed to be attracted to Hiro Takachiho as she kept smiling at him in a flirtatious way.
Simultaneously, she is one of the team's most responsible members, which had initially made her dislike Go-Go Tomago. Honey is outgoing and optimistic, and she is the most caring and compassionate member of Big Hero 6.
Graduating to full-fledged "secret agent" status, Miyazaki adopted the codename " Honey Lemon" (inspired by her favorite television program of the same name). Inspired by the exploits of Sunfire, Japan's national superhero, Miyazaki persuasively lobbied her superiors in Naichō for a spot on the team. Soon after, the top-secret consortium of Japanese politiciants and business entities known as the Giri Corporation began recruiting candidates for Big Hero 6, which was to become Japan's premiere superhero team. Although Miyazaki's team was responsible for several innovations in surveillance technology, by far their most significant invention was the " Power Purse". Miyazaki's stunning looks and sharp intellect made her a prime candidate for secret agent status, and she was promptly placed on a research and development team consisting of Naichō's top physicists, chemists, and mechanical engineers and put to work creating new technology for the government. She was enrolled in the graduate program at the Tokyo University of Science when she was recruited by the Naikaku Jōhō Chōsashitsu (Naichō), Japan's premiere intelligence agency.
