Daiya is the youngest member of Norisuke Higashikata IV's progeny at 16 years of age. She personifies a certain kawaii, between the toy-like nature of her Stand's appearance and the game-playing it facilitates, her childlike possessiveness of and offense at Josuke Higashikata's betrayal, and the playful manner of her speech. She is close to her father, who tends to spoil and is overprotective of her, and she returns this affection for her father.
