Tooru Kazama, a five-year-old Kasukabe resident, attends Futaba Kindergarten's Sunflower Class as Shinnosuke Nohara's classmate and friend. His neatly groomed appearance features styled black or dark blue hair with a distinctive tuft near his left eyebrow, typically paired with a sky blue long-sleeve or t-shirt bearing a white collar, orange shorts, white socks, and black shoes. He prioritizes academics, attending cram school and English classes over play, which—combined with his tendency to present himself as knowledgeable—creates a somewhat snobbish demeanor. Secretly, he harbors a strong affection for anime and manga, particularly magical girl series like Magical Girl Moe-P. His crushes on characters Ai, Midori, Hanako, and Torma include a marriage proposal to Ai that resulted in a slap, an incident he attempted to hide. Kazama shares a complex yet close bond with Shinnosuke. Though frequently exasperated by Shinnosuke’s teasing, leading to verbal disputes, their friendship runs deeper than with other peers. Kazama consistently denies Shinnosuke’s declarations of best friendship, yet they demonstrate mutual reliance: Shinnosuke remains a steadfast companion during Kazama’s frustration or loneliness, culminating in Kazama tearfully chasing Shinnosuke’s departing train after avoiding a group farewell. Their friendship includes physical affection, with multiple friendly kisses. He exhibits a strong attachment to his mother, occasionally implying an Oedipus complex, while his father resides abroad. Kazama sometimes seeks acceptance among upper-class children to join elite circles, though Shinnosuke’s disruptive behavior often thwarts these efforts, causing peer disinterest. He comforts Masao Sato during emotional distress, forming another close friendship. Interactions with Shinnosuke’s infant sister, Himawari, involve teasing from Shinnosuke about potential romantic feelings; episodes depict mutual blushing and hand-holding, with narrative hints suggesting a possible future marriage as a recurring romantic subplot. Kazama shows proficiency in English, calligraphy, football, baseball, and mathematics, and belongs to the Kasukabe Defense Organization. He displays mixed reactions—from enjoyment to discomfort—to having his ear blown on. He appears in films such as *Bakuhatsu! Onsen Wakuwaku Daikessen* (Movie 7) and spin-off series like *Crayon Shin-chan Spin-off*.
