**Kei Shirogane** (白銀 圭しろがね けい, *Shirogane Kei*) is a supporting character in the Kaguya-sama wa Kokurasetai series. She is the younger sister of Miyuki Shirogane, a third-year middle school student at Shuchi'in Academy and the current treasurer of the middle school Student Council.

## Appearance

Kei is a young girl with waist-length white hair that has bangs swept to the left side, blue eyes and an ashen complexion.

She usually wears the middle school uniform and a frilly hairband with a pearly accessory. She has a variety of fashionable casual outfits outside of her school uniform.

## Personality

Kei seems to share many of the same characteristics as her older brother, being a hard worker and unwaveringly kind and self-sacrificial. Being from a low-income family, she places a heavy emphasis on money and goes through great lengths to not spend much. To others outside her family, she comes off as calm and composed, though she is apparently good friends with Chika Fujiwara and her sisters. Her similarities with her brother extend so much to the point that she seems to have developed a nervous attitude towards Kaguya Shinomiya due to great admiration.

Despite being so much like her older brother, Kei and Miyuki don't get along as Kei is going through a rebellious stage in her life. As a result, she is somewhat mean and abrasive towards her family, particularly Miyuki, as he continually nags and treats Kei like a child. Though she refuses to admit it, Kei cares about her brother and is genuinely interested in his personal life, though her pride has prevented her from asking him about it directly. Instead, she is often seen awkwardly stretching around Miyuki when he is trying to figure out how to confess to Kaguya.

## History

Kei is part of the Shirogane family where she is the sister of Miyuki Shirogane. Seven years prior to the events of the series, Kei left with her mother after her parents separated, but she later ran away and returned to live with her father and brother.

## Etymology

* The name **Kei** means "gemstone" (圭).
* Kei's surname **Shirogane** means "white silver" (白銀).

## Trivia

* Kei incredibly adores Kaguya Shinomiya, to such an extent that it may resemble a crush (she greatly admires her) and often becomes a cause for jokes in the plot. However, later chapters reveal that Kei perceives her more as an excellent role model and an ideal wife for Miyuki Shirogane than a potential love interest.
* Kei has the same addiction to coffee as Miyuki and normally drinks it black.
* Apparently, Kei also does part-time jobs as she once implied that buying a certain piece of clothing would cost her 450 newspaper delivery runs.
* Kei doesn't like bell peppers.
* Kei's LINE icon is a picture of a lemon tea juice box, which she also was drinking at the end of chapter 39.
* Kei manages the family finances.
* Kei is actually very proud of her brother.
* Kei labels Miyuki "Dumbass" in her contact.
