Aoi Himawari, known as Jesse Martin in the English dub, is a 19-year-old American assistant for a racing team. She supports the team's supervision and owner, serving as an emotional anchor for the group during times of low morale or high stress. On one occasion, when the team's owner considered withdrawing from a critical race after a key pilot was hospitalized, Aoi persuaded him against this decision. Her intervention motivated the team's coach to step in as a substitute midfielder, allowing the team to continue competing. Aoi consistently offers encouragement and maintains a positive atmosphere for her fellow team members.
