She has a habit of describing things with unusual ideophones such as "るん" (Romanji: run) or "ピピツ" (Romanji: pipitsu).
Like her sister Sayo, Hina has sharp green eyes and light, wavy teal hair. However, her bangs are brushed towards the right, and her hair is shoulder-length. Sections of her hair are worn on either side in a braid held by tiny yellow bows.
Her casual attire is fairly tomboyish, featuring pants or shorts and a gingham jacket worn on, or around her waist. During performances, however, she wears frilly and feminine outfits, keeping in theme with the other band members.
A natural genius with an impeccable memory, Hina can acquire and master new skills very quickly, often even with just one attempt. She is very cheerful and carefree, but her relaxed mindset also makes her unable to understand other people's emotions. With this, Hina is also very candid, always being honest and sure of both herself and her actions.
Unlike Sayo, who dislikes being a twin, Hina seems to embrace it. She is very supportive of her sister and loves her regardless of how she treats her, but they often get into arguments due to their conflicting personalities.
