Nijukki Hinako is a third-year student at Hanasakigawa Girls' High School and 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.

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.

pitch: high and annoying
