Tōru Nakama stands as one of the two central protagonists in the series, invariably portrayed alongside his friend Hiroshi Kato. He embodies a delinquent persona through frequent physical altercations and troublemaking within a high school environment. His iconic visual traits include a distinctive hairstyle—alternately described as a punch perm or slicked-back pompadour—and an exaggerated swaggering gait.

The narrative consistently thrusts Tōru into conflicts with rival student factions, ignited by trivial provocations like stolen school trousers or interpersonal deceptions, such as a girlfriend-related scheme orchestrated by antagonists. These scenarios underscore his combative disposition and eagerness for physical confrontation. Across all adaptations—spanning the original manga, seven live-action films, a television drama special, and an original video animation series—Tōru remains inseparably linked to Hiroshi. Their dynamic anchors the storyline, revolving around shared delinquency, disruptions to school life, and clashes with authority figures or rival gangs.

The available materials uniformly focus on his role within the duo’s exploits, omitting significant evolution in core traits. No details emerge regarding his background history, personal motivations, relationships beyond Hiroshi, or individual character development. The adaptations maintain a steadfast emphasis on his function within the central pair and adherence to the established delinquent archetype, without delving into deeper narrative layers specific to him.
