Tōru Ishikawa, a student in Class 3-1, stands out with his purple swept-back hair, fair skin, and athletic frame, often clad in his school uniform accentuated by black wristbands edged with a pink stripe. His affluent upbringing unfolds within the walls of a stately home managed by housekeeper Kayo Yashiro, who oversees his routines and prods him about his school life, including his interactions with classmate Yuki Yoshikawa. Nursing a crush on Kyouko Hori, he clashes with Izumi Miyamura, fueled by jealousy over their bond—culminating in a heated physical confrontation. After Hori rejects his confession, he withdraws briefly before reconciling with their relationship, maturing into a steadier, supportive presence among friends. His dynamic with Yuki Yoshikawa deepens when they forge a pretend romance to deflect another suitor’s advances, a ruse that slowly uncovers genuine mutual attraction. Though initially misreading each other’s signals, they navigate lingering uncertainties, culminating in shared affection. He respectfully declines Sakura Kouno’s heartfelt confession, choosing to prioritize his evolving connection with Yuki. Friendship with Miyamura proves layered: as Miyamura’s first male confidant, he learns of his tattoos and piercings early, cementing trust. Their bond wavers between lighthearted camaraderie and rivalry, with Ishikawa’s insecurities surfacing in absurd, jealousy-tinted nightmares where friends morph into animals. A self-proclaimed "disappointing handsome guy," he balances academic struggles with athletic prowess, masking his wealthy background with unassuming charm. His fear of heights triggers unease even in elevators, while quirks like a melon allergy, fondness for sakura cookies, and a hereditary long tongue add texture to his persona. Despite his family’s opulence, he remains the grounded foil to his peers’ eccentricities.
