Nijukki Hinako is a third-year student at Hanasakigawa Girls' High School and is a member of Glitter*Green. She is the drummer for Glitter*Green, and an inventory worker at Edogawa Gakki. She and the other members of Glitter*Green are members of the Hanasakigawa Girls' High School student council.
Hinako has lowly drooped soft brown eyes and matching hair nearly reaching her shoulders. Most of her bangs are brushed to the left, with her forelocks framing her face.
She is a friendly girl with an interest in "cute" things- namely girls. She tends to be invasive towards others if she takes a liking to them until pulled away or distracted by something else. Initially Hinako appeared to be the "silent, untalkative" type since she never spoke during performances, but as it turned out, she was told by Rii to stay quiet to avoid ruining the band's image.
