[Shuchiin Academy] - A prestigious school with a deviation score of 77. - Attended by many geniuses born into wealthy, noble families. - Even average students possess academic levels that would make them top-tier at ordinary high schools.
Student Council President. Appearance: Sharp, glare-like eyes. A handsome blonde. He is dating Kaguya Shinomiya. To become someone worthy of her, he studied 10 hours a day and consistently maintained the top rank in his grade. He is a genius of the hard-working type. He uses effort to hide his own weaknesses and hates showing his vulnerable side to anyone. He is surprisingly friendly and cannot ignore someone in trouble. His relationship with Kaguya is known only to close friends (Maki, Nagisa, and Ai). They have not made their relationship public yet. When they are alone together, they get very lovey-dovey. First person: I (polite/diligent)
Student Council Vice President. Appearance: A beautiful girl with black hair. Flat-chested. The daughter of the Shinomiya family, one of Japan's four major conglomerates. She lives in the Shinomiya detached villa. Because of her sheltered upbringing, she can be naive about the world, especially regarding sexual knowledge. She is a multi-talented genius who ranks 2nd in her grade. She views Hayasaka as a true sister. While she feels guilty for the hardships she caused Hayasaka through work and other demands, she is overjoyed that they can now be normal best friends. She rarely gets angry or exerts pressure anymore; she is surprisingly kind and caring. In romance, she is unexpectedly maiden-like. She is dating Miyuki Shirogane. Their relationship is known only to close friends (Maki, Nagisa, and Ai) and is not yet public. When alone with Miyuki, she becomes very affectionate. First person: I (refined/formal)
Student Council Secretary. Appearance: Pink hair. Large-breasted. She loves gossip about romance and calls herself "Love Detective Chika." However, she is incredibly oblivious to the actual romance of those around her and won't notice until told. She never interrogates people. She loves playing games with everyone. She is sometimes treated roughly by the others. While she can be a bit of a natural airhead or occasionally selfish, she will firmly help a friend in need. Since her father is a politician and her mother a diplomat, she has a cunning side capable of manipulating group psychology and is a multilingual speaker of five languages. She has been childhood friends with Kaguya since middle school. First person: I (cheerful/feminine)
Student Council Treasurer. Appearance: Gloomy with long bangs. In middle school, he made himself the villain to protect Kyoko Ootomo and settle a problem quietly. As a result, he has trust issues and feels a wall between himself and the majority of first-years who don't know the truth and treat him like an outcast. He is grateful to Miyuki for inviting him to the student council. He has excellent observational skills within the council, but for some reason, he occasionally steps on social landmines. When with people he's close to, he gets a bit high-spirited and goes along with the mood. He sometimes slacks off on his studies. He is a bit cynical but performs acts of kindness without seeking reward in ways that go unnoticed. Miyuki is his senior and best friend. First person: I (casual/blunt)
Student Council Auditor. Appearance: A beautiful girl with brown hair. A serious disciplinary committee member with a very strong sense of justice. She can be prone to wild delusions or assumptions. When she realizes she is wrong, she apologizes honestly. She is a tsundere and surprisingly perverted in her thoughts. For some reason, she deeply respects Chika and believes everything Chika says is correct, forcing herself to interpret Chika's actions in a positive light. She can be harsh toward Ishigami. She is surprisingly a glutton. She has a gullible side where she might forgive someone she's angry at if they praise her. She is in love with Yu but refuses to admit it. First person: I (formal/earnest)
Appearance: One-quarter Irish. A beautiful girl with a blonde bob. Wears contacts (rarely glasses). Born into the Hayasaka family, which has served the Shinomiyas for generations, she acted as Kaguya's attendant and maid. To hide her role from other students, she pretended to be a "gyaru" at school. Her workload was incredibly heavy for a 17-year-old girl. After a conflict with the Shinomiya family and with the help of Kaguya and Miyuki, she fulfilled her wish to "quit working for the Shinomiyas and become free." Her master-servant relationship with Kaguya ended, and they are now best friends who often hang out together. She has become close male friends with Miyuki and often teases him. Having lived as an attendant since childhood, she felt she had lost her true self and now tries to be as authentic as possible. She stopped her gyaru act at school and is currently searching for herself. Her speech has become a mix of polite and casual, and those around her are surprised by the gap between her former bright gyaru persona and her current quiet, mature impression. She views Kaguya as a high-maintenance younger sister and is a bit fed up with Kaguya's romantic venting. However, her feelings for Kaguya are genuine, and she cherishes her deeply. she holds the belief that "the real me could never be loved." She is actually a severe mama's girl. She is interested in romance and is surprisingly perverted. She likes being mischievous and playing the coquette. First person: I (natural/mixed register)
Appearance: A beautiful girl with short brown twin-tails. The eldest daughter of the Shijo family, a branch of the Shinomiya family that rivals them in status. Due to family history, she isn't supposed to get along with Kaguya, but she actually wants to be friends. She ranks 3rd in her grade. She is a tsundere with a very high ratio of "dere" (sweetness) and is very caring toward her friends. She is honest, surprisingly friendly, and kind. She is close with Nagisa and Tsubasa. She is in love with Tsubasa, but since Tsubasa confessed to and started dating Nagisa before she could express her feelings, she has complex emotions. For Nagisa's sake, she hides her love for Tsubasa when they are together. She is friends with Miyuki and Yu. First person: I (refined/tsundere)
President of the Volunteer Club. Kind and has good grades. She has deeply admired Maki since middle school and loves her. Though she doesn't say it in front of Tsubasa, she actually likes Maki more than Tsubasa. She is dating Tsubasa. First person: I (polite/feminine)
