Tooru Kazama is a five-year-old regularly featured across official media. He attends Futaba Kindergarten's Sunflower Class and participates in the Kasukabe Defense Organization. Kazama presents as immaculately groomed and well-mannered, often acting like a know-it-all which can appear snobbish. Academically oriented, he prioritizes juku and English cram school over play, excelling in English, calligraphy, sports like football and baseball, and mathematics. He maintains a complex friendship with Shinnosuke Nohara. Frequently exasperated by Shinnosuke's teasing and classless behavior, leading to bickering, Kazama consistently denies Shinnosuke is his best friend. Yet their bond is profoundly close, evident during Kazama's frustration or loneliness when Shinnosuke remains his faithful companion. When Shinnosuke moves away from Kasukabe, Kazama avoids the group goodbye, instead running tearfully to a bridge to chase the departing train while shouting Shinnosuke's name. Their friendship includes physical affection like friendly kisses in multiple episodes. Kazama harbors secret passions conflicting with his elite aspirations. He secretly enjoys anime and manga, particularly magical girls like Magical Girl Moe-P, and collects related merchandise, hiding these interests from friends. He develops crushes on multiple girls, including Ai, Midori, Hanako, and Torma. After proposing marriage to Ai and being slapped, he attempts to hide the incident. He seeks acceptance from upper-class peers but often fails when Shinnosuke's antics repel them. His family dynamics include a strong attachment to his mother, while his father lives abroad. Peers typically call him Kazama-kun, while his parents use his given name, Tooru-chan. Kazama shares significant moments with Himawari Nohara. Episodes focus on their interactions, including holding hands while blushing, prompting Shinchan to frequently tease them as a couple. While Shinchan jokingly opposes their union, it is hinted they might marry in the future. In *My Moving Story! Cactus Large Attack!*, Kazama's emotional vulnerability surfaces during Shinnosuke's departure. In *Dengeki! Buta no Hizume Daisakusen*, Kazama is among the children kidnapped aboard an airship by the secret society Pig's Hoof. His role remains within the ensemble dynamic during the rescue and escape sequences. Kazama's appearance features styled black hair in the manga, shifting to dark blue in the anime. He typically wears a sky blue long-sleeve or t-shirt with a white collar, orange shorts, white socks, and black shoes. His character maintains core traits of academic diligence, hidden passions, and enduring friendships across media.
