Aki (亜季 Aki) is Haruna's younger sister and a tsundere (a character who flips between a "cold" side and a "warm" side).[1] She initially didn't believe that Hakone was a hot spring spirit.[2]

Trivia Edit

  • Aki sounds like the Japanese word for "autumn" (秋 aki). Aki's name also contains the character for "season" (the time period).
