Tōru Ishikawa, a student at Katagiri Senior High School, begins as a confidant to Kyouko Hori before forging a meaningful bond with Izumi Miyamura. Towering and athletic, he sports short purple hair stylishly swept to the right, vivid purple eyes, and a fair complexion. His school uniform, often layered with sweaters or blazers, features casually rolled-up sleeves and black wristbands accented by a pink stripe. Initially nurturing a quiet affection for Hori, Tōru faces rejection when her feelings shift toward Miyamura. Though jealousy sparks a brief clash between the boys, Tōru’s lingering resentment softens into respect, cementing an unexpected friendship. His attention gradually turns to childhood friend Yuki Yoshikawa, their rapport blending playful jabs and miscommunication. Tōru masks his growing feelings, assuming Yuki’s interest lies elsewhere, while she remains unaware of his affection. A fabricated relationship to deflect another suitor’s confession forces honesty between them, culminating in mutual acknowledgment of their bond. When Sakura Kouno confesses to him, Tōru gently declines, solidifying his devotion to Yuki as they embrace a sincere romance. Beneath his easygoing humor and prankster charm, Tōru exhibits keen emotional insight, often acting as a skilled mediator among peers. Loyal yet privately vulnerable, he navigates insecurities while supporting friends through personal struggles. His affluent family includes a younger brother, and his quirks—a notably long tongue, melon allergy, love of action games, and fondness for sakura cookies—add distinct texture to his character. Tōru’s arc traces a journey from rivalry to self-assured maturity, balancing enduring camaraderie with blunt-witted Shū Iura against his evolving role as Yuki’s partner. His narrative threads explore reconciliation with unrequited love, the patience of friendship, and the quiet courage to embrace vulnerability, ultimately anchoring him in a relationship defined by mutual growth and trust.
