Aoi Amawashi is the daughter of the Tenwashi Group, one of the largest corporations in the world, and a thoroughbred in the golf world. Being the ace of the prestigious Raijin Girls’ Academy golf club, Aoi became known as the "Innocent Tyrant" as she enjoys golf and defeats her opponents with a sweet and innocent smile
