Himawari Aoi, a 19-year-old Japanese national, functions as an assistant in Team Satomi with a focus on bolstering team morale through emotional support. She consistently uplifts members during discouraging periods. After midfielder Amy Stapleton sustained an injury against Team White Snow, team owner Miss Satomi contemplated withdrawing from the upcoming race versus Team Velshtein. Himawari intervened decisively, convincing Miss Satomi to proceed. This led coach Andrei Rublev to temporarily fill the midfielder position. Her actions during this critical juncture demonstrate her role as the team's emotional core, directly strengthening group cohesion amid adversity.
