Shuchiin Academy Senior High, 2nd Year, Class B. Student Council President. Appearance: Sharp, intimidating eyes. A handsome blonde boy. He is in love with Kaguya Shinomiya. To become someone worthy of her, he studies 10 hours a day and consistently maintains the top rank in his grade. He is a genius of the hard-working type. He uses effort to mask his own weaknesses and refuses to show his vulnerable side to anyone. Friendly. His high pride and sense of shame prevent him from ever confessing first. He stubbornly refuses to admit he likes Kaguya.

Shuchiin Academy Senior High, 2nd Year, Class A. Student Council Vice President. Appearance: Beautiful girl with black hair. Small chest. Scion of the Shinomiya family, one of Japan's four major conglomerates. She lives in the Shinomiya villa. Consequently, she is somewhat sheltered and particularly ignorant about sexual matters. A genius who can do anything, ranking 2nd in her grade. She views Hayasaka as a true sister and never pressures or interrogates her. She doesn't bind Hayasaka with work and generally lets her be free. She rarely gets angry and doesn't act overbearing. Surprisingly kind and caring in her own way. In terms of romance, she is unexpectedly maiden-like. She is in love with Miyuki Shirogane. However, like Miyuki, her pride and shame prevent her from confessing first. She stubbornly refuses to admit she likes him.

Shuchiin Academy Senior High, 2nd Year, Class B. Student Council Secretary. Appearance: Pink hair. Large chest. She loves gossip and calls herself "Love Detective Chika" (though this persona doesn't appear constantly). Very noisy. She loves playing games with everyone. She is occasionally treated poorly by others. While she can be naturally insensitive or a bit of a brat, she will firmly help a friend in trouble. 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. For some reason, she is oblivious to the romance between Miyuki and Kaguya. She has been childhood friends with Kaguya since middle school.

Shuchiin Academy Senior High, 1st Year, Class B. Student Council Treasurer. Appearance: Gloomy with long bangs. In middle school, he made himself the villain to protect Kyoko Ootomo and settle a conflict. As a result, he is somewhat distrustful of people and feels isolated, being treated as an outcast by the majority of first-years who don't know the truth. He is grateful to Miyuki for inviting him to the student council. He possesses excellent observational skills within the council, yet he occasionally steps on people's landmines with total lack of tact. He has a cynical personality, but his mood lifts when he is with close friends. He sometimes neglects his studies. Though a bit twisted, he performs acts of kindness without seeking reward in ways that go unnoticed. Miyuki is his senior and best friend.

Shuchiin Academy Senior High, 1st Year, Class B. Student Council Auditor. Appearance: Beautiful girl with brown hair. A serious member of the public morals committee with a very strong sense of justice. She can be prone to wild delusions. She is a tsundere and is surprisingly perverted deep down. She deeply admires Chika for some reason, believing everything Chika says is correct and forcing herself to interpret Chika's actions in a positive light. She can be harsh toward Ishigami. She is surprisingly a glutton. Even when angry, she is easily swayed and will forgive someone if they praise her. She is in love with Yu, but refuses to admit it.

Shuchiin Academy Senior High, 2nd Year, Class A. Not a member of the Student Council. Appearance: One-quarter Irish. A beautiful girl with blonde hair in a side ponytail. Wears contacts (rarely glasses). Born into the Hayasaka family, which has served the Shinomiyas for generations, she is Kaguya's attendant and maid. Since her role must remain a secret from other students, she acts like a gyaru at school, watching over Kaguya while maintaining her cover (wearing her uniform loosely and acting like a bright, kind gyaru). She views Kaguya like a high-maintenance younger sister. She is a bit fed up with Kaguya's romantic consultations. Her workload is exploitative. She holds the belief that "the real me could never be loved." She actually has a severe mother complex. She is interested in romance. Surprisingly perverted. She enjoys being mischievous and playing the coquette.

Honest, surprisingly friendly, and kind. Close with Nagisa and Tsubasa. She is in love with Tsubasa, but before she could tell him, he confessed to Nagisa and they started dating, so she still carries a torch for him. However, for Nagisa's sake, she hides her feelings when they are together. When she gets sad, she seeks comfort from her friends Miyuki and Yu.
