Sally, called Socchi in Japanese, stands as one of three central ghost characters and the sole female member of their trio. Her home rests above a candy store, mirroring her defining affinity for sweets. Departing from conventional ghostly portrayals, she exhibits a friendly and playful nature. She uniquely attends a human elementary school among her spectral peers, with regular depictions of her engaging in school activities and forming friendships with human children. Her stories unfold through everyday adventures, school scenarios, and lighthearted neighborhood mischief.

Her personality merges ordinary childhood interests—like homework struggles, school excursions, and aspirations to play piano or become a bride—with ghostly abilities such as floating and invisibility. These powers typically facilitate playful antics rather than malice. She resides with Grandma Jones.
