Хікава Хіна

Hina is a second-year student at Haneoka Girls' High School and is the guitarist of Pastel*Palettes. She is the younger, more bright-eyed twin of Sayo.

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, and as such doesn't sometimes notice if she's insulting them. With this, Hina is also very candid, always being honest and sure of both herself and her actions, though at times she ends up being more blunt than honest.

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. To add to this Hina wants to do most things together with her, but this ultimately has lead to Sayo quitting most of her hobbies as she felt like Hina was just copying her and then always did it better than her, thus feeding into her inferiority complex more.
