Hina Hojo performs as a third-generation idol under Sweetfish Productions. She is the younger sister of China and Mina Hojo, the first-generation idol duo Chocorat Sisters. Hina deeply admires her older sisters, often speaking of their achievements with visible pride and enthusiasm, continuing until someone interrupts her.

She expresses keen interest in baking and pastry-making but consistently demonstrates a lack of skill in this area. Her culinary attempts invariably result in explosive failures, though these incidents cause no physical harm. This flaw extends to general ovenware usage, exemplified when reheating miso soup in a microwave caused another explosion.

Her specialty within the idol group is theater acting. The explosive cooking mishaps remain a recurring aspect of her characterization.
