Who Is The Smartest Character In Kaguya-Sama: Love Is War?

Kourtney Elijah is the eldest daughter of the Elijah family in New York. Due to her stepmother's scheme, she was sent to the countryside by her despicable father at a young age. When the patriarch of the Elijah family celebrated his 60th birthday, they brought her back. She returned quietly, only to be mocked as a rural underachiever and poor girl, which angered the influential figures. A professor from a prestigious university said, "Underachiever? That's a joke! Let me introduce you to the genius who top universities worldwide are vying for!" A billionaire exclaimed, "Poor girl? Nonsense! All my wealth is thanks to Kourtney's contributions!" A certain man declared, "This is my wife. Whoever dares to mock her, I will annihilate them!"

The Ivanovas and the Vitales are well-known aristocratic families who have maintained everlasting friendship through generations. My name is Anastasia Ivanova. I have been the daughter of the Ivanovas for twenty years, only to discover just now that I was switched at birth. When I was swept out of the Ivanova’s mansion like rubbish, Lorenzo, the youngest son of the Vitale family, firmly picked me up in spite of all objections. Lorenzo always acted cold and distant toward me. I didn’t know why he came to take me into his car at that time. He whispered in my ear again and again, ‌"I’ve wanted you for a long time."‌ He pinned me against the leather seat, making me cry until my voice was hoarse. At that moment, I finally understood his coldness over the years was not indifference but restraint. Soon after, Lorenzo overrode all objections to marry me. His parents were vehemently against me, but Lorenzo directly stripped them of power and became the youngest godfather. Scarlett Montgomery tried to stop us from getting married, but Lorenzo canceled all her credit cards and threatened to send her away. I thought we would have a happy life. Three days before our wedding ceremony, he planned to send me abroad, claiming enemies might retaliate. But, I accidentally overheard him talking to Scarlett in the hallway at night. "Thank goodness. You tricked her into leaving until after I give birth. You’re so good to me!"‌ He kissed her cheek, ‌"I don’t want Anastasia know our affair. You must keep it secret."‌ Their dialogue made me devastated. But I didn’t confront him immediately. Instead, I quietly completed my immigration paperwork as a way to make a clean break with him.

At the celebration, the pampered heiress in Crownridge, Aveline Sage, confessed her love for me in front of the entire school. I turned her down flat. I was one of the Sage family's candidates—handpicked top students from every state—to improve their next generation's genes. In a few days, when the exam results came out, whoever earned the highest national score would become her fiance. For three years straight, I had been ranked first in the country. In my previous life, I achieved that top score. I got engaged to Aveline and became the envy of everyone—the son-in-law of Crownridge's most powerful family. But on the day of our engagement, her first love, Caspian Lorne, jumped off the top of the Sage Group building. His body was shattered beyond recognition. Aveline hired the best mortician to restore his face and placed him in a crystal coffin, where she slept beside him every night. During our honeymoon, she brought Caspian's body along, then kissed and clung to him right in front of me. When I confronted her, she looked at me with disgust. "The Sage family sponsored your education for twelve years. You knew Caspian and I were in love. Couldn't you let him win just once? You've been in first place for twelve years. What would it have cost you to lose? You ruined his future, ruined our love. You deserve to die." She drugged me, turned me into a fool with the mind of a three-year-old. I couldn't recognize my parents. I lost control of my own body. And I died in agony. … Then, I opened my eyes again, back on the morning of the exam. Last time, I beat Caspian by a single point. This time, I left an answer blank. Let him be the top scorer. Let him marry her. I hoped they grew old together, with plenty of children to match their love.

My younger sister, Joey Crawford, and I have taken the exam 20 times in a row. Yet, our answer sheet shows the exact same answers every time. No matter how fast I complete the exam, Joey is able to turn in her paper one second before me. My homeroom teacher, Mr. Harris, has spoken with me three times regarding this matter. At the same time, I receive my first warning for cheating on the exams. Whenever my classmates see me, they say to me, "Hey, cheater! You got busted this time, huh?" The thing is, I've never even touched Joey's paper. How can our answers be exactly the same? During the college entrance exam, I suddenly awaken to the ability to see the live comments dangling in midair. "The female lead is the chosen one! It must feel amazing to have awakened the mind-reading ability and all!" "She relies on reading the side character's mind just to obtain all the answers. So what if the side character excels in her studies? Her role is to become the female lead's stepping stone to success!" It turns out that Joey has been stealing my answers by reading my mind this whole time. As I flip the exam papers over, I start singing the alphabet song mentally. "A-B-C-D-E-F-G…"

Evy was a simple-minded girl. If there's work she's there. Evy is a known workaholic. She works day and night, dedicating each of her waking hours to her jobs and making sure that she reaches the deadline.

I was like the pure and innocent Cinderella of a school romance novel. Unlike the aristocratic students around me, I didn't come from wealth or privilege. I earned my place at this elite academy through merit alone, my high scores opening the gates to a world far beyond my means. Cinderella is supposed to be stubborn, proud, and righteous—standing tall despite her humble origins. But I have none of those qualities. All I have is poverty.
