Hina Hōjō is the younger sister of China and Mina Hōjō, members of the original idol group the Chocorat Sisters. She idolizes her older sisters, expressing immense pride and admiration for them. Hina gushes about her sisters at length unless someone interrupts her.

Outside her idol activities, Hina enjoys baking pastries despite struggling with the skill. Her culinary endeavors often result in the pastries dramatically exploding, though without causing harm. This tendency extends to other kitchen tasks, like heating miso soup, which has also exploded. Her mishaps indicate significant difficulty operating oven-based appliances.

Hina released a solo character song CD featuring the tracks "candy (bitter&sweet)" and a solo version of "Love, Love, Love no Sei na no yo!". She performs as part of the third-generation Lovely Idols.
