Kasumi Nakasu, (中須(なかす) かすみ) is one of the 10 school idols in the Nijigasaki High School Idol Club. She is a first year at Nijigasaki High School. Her image color is yellow. She is a member of QU4RTZ, a subunit under the Nijigasaki High School Idol Club.

She is voice acted by Sagara Mayu (相良 茉優).


A first-year at Nijigasaki High School. She loves cute things and admires school idols far more than the average person. She hates losing, and gets angry when people call her by her nickname, Kasukasu. She'll do all sorts of mischief to overcome her rivals, but often ends up doing what everyone else does.


Kasumi is a cutesy and energetic girl who focuses on becoming the top idol in Japan. Because of that goal, she despises loosing to anyone and will often resort to cheating or sabotage. Whenever she tries to come up with plans however, they often fail or aren't as bad as she believes they are. Due to this, she's often a sore loser.

Despite everything, Kasumi is a very kind and caring person. She'll often try to cheer up her friends when they're feeling down or just try to be kind. This is seen a lot when the girls are worried and Kasumi tries her best to be cheerful. Like when she tries to rile up the group to help Ayumu come over her nerves or encourage the others. She'll even exchange heartfelt Christmas gifts with the other members.
