A shoemaker from the moon, Haruka came to Rolling Town interested in Dan and Co.'s BFB skills. She develops special basketball shoes for their Big Foots in order to promote her business.

Also know as "Lunar Bust," she is a mature lady with long white hair, fair skin, massive breasts, and wide hips. She wears a short black dress that exposes most of her long legs, with white trims and ample cleavage. She also dons black heels, crescent moon earrings, black anklets, and a pair of black shades. Being from the Moon, her massive breasts are a result of low gravitational pull.

Haruka has a foot fetish, which leads her to unintentionally tickle Dan mercilessly while caressing his feet upon their first encounter. She also loves kissing and wrapping Dan's feet around her massive breasts when she gets excited. Despite this, Haruka also has the curious ability to read people's thoughts just by looking at their feet.
