Hitori is a high school girl with long, straight pink hair featuring full bangs and two distinctive cube hair accessories—one blue, one yellow—pinned on her right side. She has wide blue eyes that frequently reflect her inner panic. She almost always wears an oversized pink track jacket pulled over her school uniform, preferring to blend into the background. When playing, she wields a black Gibson Les Paul Custom guitar.
