Nagisa Kashiwagi (柏木 渚かしわぎ なぎさ, Kashiwagi Nagisa) is a supporting character in the Kaguya-sama wa Kokurasetai series. She is a second-year high school student at Shuchi'in Academy, the president of the Volunteering Club, and the girlfriend of Tsubasa Tanuma.


Nagisa is a young girl with short dark brown hair, dark brown eyes and a double-banded hairpin on the left side. She wears the standard Shuchi'in Academy high school uniform.


Nagisa has a friendly demeanor to people especially to her classmates. She cares a lot about her boyfriend, Tsubasa and her close friend Maki. She has a tendency to gossip about relationships and romance, usually with Kaguya.

She exhibits many typical girlfriend behaviors such as talking a lot, being moody, or even jealousy to the point where she hires a private detective to spy on her boyfriend to see if he is having an affair, later making up with him by being very physically bold and passionate.[1][2]


Nagisa is the daughter of the chairman of a major shipbuilding company and Miyuki's classmate. She has excellent grades and academically ranks in the top ten of her class.[3]

Early in the series, she is confessed to by a classmate, and ends up accepting on a whim.[4] After that, she started to occasionally ask Kaguya about what to do in her relationships and vice versa.


  • The name Nagisa means "beach, shore" (渚).
  • She's also one of the academy's VIPs.[5]
  • The last name Kashiwagi means "oak tree" (柏木)
  • In Chapter 138, Nagisa tells Kaguya that it was about two months after the first kiss before she and Tsubasa (Nagisa's boyfriend) started having sex, but it took about 40 seconds after the French kiss.
