Kasumi Nakasu

Kasumi Nakasu is one of the main characters of Love Live! Nijigasaki High School Idol Club. She is a first year at Nijigasaki High School. Her image color is pastel yellow. She is a member of QU4RTZ, a unit under the Nijigasaki High School Idol Club.

Background
Kasumi had always dreamed of becoming an idol. Upon entering Nijigasaki, Kasumi would go on to join the School Idol Club as its most passionate member. But when the club fell into disarray, Kasumi's dreams never took off, and she would soon begin to doubt herself. Her sole presence in the club room would serve as a reminder that the School Idol Club has seen better days. Nevertheless, Kasumi still believes in the club and is determined to keep the dream alive. She would continue to strive to become a school idol and hopes to once again participate in club activities, especially with a senpai she adores. Along with Karin Asaka and Setsuna Yuki, she works with Dengeki Online.

Personality
Kasumi loves all things cute, and her love for idols is unrivaled in strength and inspiration. Kasumi wants to be number one in any competition she's in, and often resorts to cheating or even sabotage to achieve that goal. As a consequence, she is a sore loser whenever she achieves anything other than first place.

She hates the nickname Kasukasu (かすかす) which roughly translates to "just barely" or "not quite", and gets in a bad mood when referred to with it.

Kasumi spends a lot of her time scheming or thinking up new ways to ensure her own victory; however, these plans often fail or aren't as devious as she thinks.

Kasumi can also be considerate of her fellow idols and is seen doing things to cheer them up or to be nice to them. For example, she tries to rile up the group when Ayumu Uehara is nervous before their live, and exchanges genuine Christmas gifts with the Dengeki Online group.

Clubs and Hobbies
She enjoys making bread and watching idol videos. Her favorite school subjects are science and home economics, but she dislikes classical literature and history.

Trivia

 * Kasumi fulfills the pure attribute of the Nijigaku first years.
 * Kasumi claims to hate the nickname "Kasu" because it was overused in the past, particularly by people she had falling outs with. She adamantly suggests her own nicknames instead, usually asking people to either call her by her full name or Kasumin.
 * Kasumi has matching nicknames for Shizuku Osaka (Shizuko), Rina Tennoji (Rinako) and Shioriko Mifune (Shioko) because they're all first years. When Rina suggested calling Kasumi 'Kasuko' so they could truly match, Kasumi got upset.

Anime-specific

 * Unlike her game counterpart, Kasumi doesn't wear her moon hair clip.
 * Kasumi is the second character since Ayumu to directly confess to someone (in her case, Shizuku Osaka), with Shizuku blushing as a response.
 * But whether she is (possibly) confirmed as a homosexual like Rin Hoshizora in School Idol Diary: Spring-Colored Valentine manga has yet to be determined, given that both Kasumi and Shizuku were paired prior to the former's confession.
