Mitsuhashi Takashi begins as a high school transfer student seeking reinvention as a prominent delinquent, abandoning his ordinary life. He adopts a distinctive blond hairstyle to cultivate an intimidating image. His family includes parents; his father spins unconvincing tales of heroism while his mother remains skeptical. Personality-wise, Mitsuhashi blends cunning pragmatism with self-centeredness, prioritizing his own safety and frequently using deception or manipulation to evade trouble. Driven by greed and a win-at-all-costs mentality, he occasionally reveals a softer core through displays of loyalty or protectiveness. He favors speed and evasion in confrontations, sometimes surprising himself by blocking attacks. A strong possessiveness defines him, triggering aggressive responses to theft or mockery of his belongings or reputation. Habitual lying creates "crying wolf" scenarios where others dismiss his claims of innocence until proven. Relationships are central to his journey. He partners with Itou Shinji, forming the notorious "Nan High Duo," balancing Mitsuhashi's trickery against Itou’s righteousness. Their dynamic evolves from mutual pretense to genuine camaraderie. Mitsuhashi develops a romantic connection with Riko Akasaka, who affectionately calls him "San-chan" and recognizes his hidden vulnerability. Their bond deepens through shared conflicts, like protecting her family’s dojo, though he frequently clashes with her father. Rivalries with figures like Imai Katsutoshi (physically strong but less cunning) and Sagara Takeshi (a persistent antagonist) drive recurring conflicts, while minor characters like "Fundoshi Mask" hold grudges he casually forgets. Character development occurs across key arcs. Initially, Mitsuhashi and Itou feign toughness, relying on dirty tricks, but gradually evolve into genuinely skilled and respected delinquents through relentless brawls. The Saipan arc introduces darker challenges, including confronting an attempted rape and gunfire. Final storylines depict heightened stakes, like Sagara targeting his friends with brutal tactics, culminating in Mitsuhashi publicly renouncing his delinquent identity during a climactic battle. Throughout these experiences, his protective instincts surface more frequently, especially toward Riko and close allies, marking his shift from pure self-interest to invested loyalty.
