Horse racing is popular in Pangaea, with the city of Avelon being the center of the sport. Being naturally flexible, fast, and having a strong physique, the young Alba soon became one of the rising stars of the racing industry, garnering numerous wins in a variety of contests. Due to her popularity, her family resorted to using her income to sustain their needs. Wherever the young Alba went, people were sure to recognize her long, flaxen hair and radiant aura.

However, the pressure of restricted freedom and being the sole family breadwinner caused Alba to become paranoid of her fame. With the help of some supportive family members, Alba took on a new appearance and changed her name to Heather. She then moved to the city of Laurentia to start a new life, often wearing a mask whenever she goes outside to reduce people's suspicions of her being the missing Alba.

Not many people who know Heather recognize her as Alba due to her cowardly personality, but those who do know keep it a precious secret.

Currently, Heather is a high school student at Cambria University alongside her three close friends: Shiba, Millie, and Tonia. She is a member of the Cooking Club. Despite being invited to join many times, she refuses to become an official member of the track team, preferring to merely watch them from the sidelines.

A single look at Heather and one can already tell what kind of personality she possesses. With a closed body language and a meek voice, she comes off as timid and cowardly towards her peers, and is regarded as a 'gentle giant' in her grade level due to her tall stature. Although her stuttering voice often makes her words seem unintelligible to the majority, she is able to express her thoughts comfortably to the people she trusts the most. However, Heather's current personality is different from when she was younger—back when she still went by her birth name, Alba.

Due to her debut in the horse racing world, Alba possessed a lot of self-confidence, having been one of the most sought-after racers in the industry. Although not very chatty, she tended to provide substance in her words in order to keep a good conversation going. She did not let the pride of being a famous sports personality get to her, as she regularly offered advice through her commercial works to those who wanted to become as physically fit as her, as well as not being competitive with her rivals. When not making public appearances, she keeps to herself and rarely goes out of her house, as she was burnt out from the many demands she had to meet and did not want to cause uproars in the public.

Eventually, the immense pressure of being a child celebrity and being the family breadwinner overwhelmed Alba. Paranoid of the fact that she will never be able to enjoy life as a normal teenage girl, she made a questionable (yet arguably reasonable, as she was still a young girl) decision of suddenly disappearing from the spotlight with the assistance of her uncle who is a government worker in Laurentia, leaving her rivals and fans with many questions.

After taking on a new identity and moving to Laurentia, Heather chose to put her past behind her, refusing to do anything related to racing competitions. She has since become a much more gentler version of her younger self, choosing to take on simpler hobbies such as baking. Whilst she is the silent type, she often gives good advice to her close friends. In terms of academics, Heather is in the middle of the spectrum. Due to her history, she rarely trusts new people and is difficult to get to know.
