Kei Shirogane is [Miyuki Shirogane](https://anilist.co/character/121101)'s little sister. She attends Shuchiin middle school and is the treasurer for the middle school student council.

She is a hard worker just like her brother and can be very prideful at times. She also inherited his sense of righteousness and hates it when someone doesn't do the right thing in a given situation. Like her brother, she likes helping out those who are in trouble even if it means going out of her way to do it. Since she grew up in a family that places emphasis on saving money, she normally carries coupons and works hard for the things she wants to buy. 

She developed a prickly attitude towards her brother due to his over protectiveness. She's also entered a rebellious phase and due to her pride and she cannot get herself to have a lighthearted conversation with Miyuki, leading into the similar mind games that Miyuki and [Kaguya](https://anilist.co/character/120649) play against each other, but her objective is to talk to Miyuki without making it look like she has a brother complex. She rarely speaks and most of the time it is only when she exchanges formalities at school or when she hurls abuses at her brother.

Known for being both brilliant and powerful, Miyuki Shirogane and Kaguya Shinomiya lead the illustrious Shuchiin Academy as near equals. And everyone thinks they’d make a great couple. Pride and arrogance are in ample supply, so the only logical move is to trick the other into instigating a date! Who will come out on top in this psychological war where the first move is the only one that matters?

After a slow but eventful summer vacation, Shuchiin Academy's second term is now starting in full force. As August transitions into September, Miyuki Shirogane's birthday looms ever closer, leaving Kaguya Shinomiya in a serious predicament as to how to celebrate it. Furthermore, the tenure of the school's 67th student council is coming to an end. Due to the council members being in different classes, the only time Kaguya and Miyuki have to be together will soon disappear, putting all of their cunning plans at risk. 

A long and difficult election that will decide the fate of the new student council awaits, as multiple challengers fight for the coveted title of president.

The elite members of Shuchiin Academy's student council continue their competitive day-to-day antics. Council president Miyuki Shirogane clashes daily against vice-president Kaguya Shinomiya, each fighting tooth and nail to trick the other into confessing their romantic love. Kaguya struggles within the strict confines of her wealthy, uptight family, rebelling against her cold default demeanor as she warms to Shirogane and the rest of her friends. 
 
Meanwhile, council treasurer Yuu Ishigami suffers under the weight of his hopeless crush on Tsubame Koyasu, a popular upperclassman who helps to instill a new confidence in him. Miko Iino, the newest student council member, grows closer to the rule-breaking Ishigami while striving to overcome her own authoritarian moral code. 
 
As love further blooms at Shuchiin Academy, the student council officers drag their outsider friends into increasingly comedic conflicts.

Shuchiin Academy’s student council room: the place where Student Council Vice President Kaguya Shinomiya and President Miyuki Shirogane met. After a long battle in love, these two geniuses communicated their feelings and, at the Hoshin Festival, had their very first kiss. However, there was no clear confession of love. The relationship between these two, who assumed they would be a couple, remains ambiguous. Now, overly conscious of their feelings, they must face the biggest challenge yet: Christmas. It’s Shirogane who wants it to be perfect versus Kaguya who pursues the imperfect situation. This is the very “normal” love story of two geniuses and the first kiss that never ends.
