Hana Toujou trains Team Rigil at Tracen Academy, leading the institution's strongest racing team with a mature, cool demeanor. Her strict, stoic approach ensures rigorous development, leaving no team member unprepared. Beneath this discipline, she occasionally reveals motherly concern, reflecting multifaceted mentorship.

She possesses a slender build, azure hair in a neat ponytail, and pink eyes framed by glasses. Her signature red lipstick and triangular earrings complement formal stone-blue attire and high-heeled shoes, projecting a professional image befitting her elite role.

Functionally, Hana prioritizes rational strategy and data-driven methods, focusing solely on victory-enhancing elements. She meticulously records data to craft efficient training regimens, emphasizing results. Her interactions with Team Spica's trainer—a prior associate—involve professional rivalry and methodological contrasts. The Spica trainer uses the informal "Ohana-san," hinting at their shared history.

During Season 2 events like the Arima Kinen race, she remains active at Tracen Academy, continuing her Team Rigil duties. Hana exists exclusively within the anime adaptation, absent from games, spin-offs, or extended media. Her background, development, and professional activities are confined to the animated series.
