Ishigami Yuu

Yu Ishigami is the treasurer of the Shuchiin Academy Student Council and a second-year student. Often referred to as the 'second protagonist' of the series, Ishigami is a complex individual characterized by his gloomy disposition, long black bangs that cover his left eye, and the constant presence of his large grey headphones. He is a tech prodigy and a master of data processing, making him an indispensable asset to the student council, despite his tendency to work from home or hide in the council room's darkest corners. Ishigami’s cynical worldview is a defense mechanism born from a traumatic incident in middle school. He attempted to protect a girl named Kyoko Ootomo from her manipulative boyfriend, but his actions were misunderstood, leading to him being socially ostracized and labeled a violent stalker. Rather than revealing the truth and hurting Kyoko, he chose to bear the hatred of his peers in silence. This burden made him a shut-in until Miyuki Shirogane scouted him for the student council, giving him a second chance at a social life. Physically, he is usually seen in the black Shuchiin Academy uniform, looking perpetually exhausted with slight dark circles under his eyes. He is an avid gamer, often escaping into virtual worlds to avoid the 'normies' and the complexities of high school romance. While he presents a blunt and sometimes tactless exterior—frequently making sharp observations that get him into trouble (especially with Kaguya Shinomiya, whom he is deathly afraid of)—he possesses a deeply ingrained sense of justice and kindness. He is the type of person who would suffer in silence to ensure someone else’s happiness, making him one of the most selfless members of the council, even if he would never admit it. As the series progresses, he slowly begins to step out of his shell, confronting his past and even attempting to pursue his own romantic interests, though his dry, self-deprecating humor remains a core part of his identity.
