Set in 1980s Japan, the series follows Takashi Mitsuhashi and Shinji Ito, two ordinary high school students who decide to drastically reinvent themselves on the very same day by transferring to a new school. Tired of being invisible and bullied, both youths independently choose to embrace the delinquent lifestyle, transforming themselves into flashy bosozoku-style rebels. Mitsuhashi bleaches his hair bright blond, while Ito adopts an gravity-defying, spiky sea-urchin hairstyle. Upon arriving at Sobu High, they cross paths and form an unlikely alliance, quickly realizing their shared secret. Though they initially clash, they bond over their mutual desire to dominate the schoolyard hierarchy and fend off actual thugs.Mitsuhashi is driven primarily by self-preservation, cunning, and an absolute lack of conventional honor. He is fiercely opportunistic, often resorting to underhanded, cartoonish tactics—such as throwing dirt, running away, or manipulating situations—to defeat much stronger opponents. Conversely, Ito possesses a rigid, old-school sense of justice and physical bravery. He fights fair, protects the weak, and is deeply loyal, making him the moral anchor of the duo. Despite their contrasting personalities and constant bickering, their complementary strengths make them an unstoppable fighting force against rival gangs from neighboring schools.As their reputation spreads across the prefecture, Mitsuhashi and Ito constantly attract trouble. They must navigate turf wars, jealous delinquents, and vengeful leaders who view the duo’s meteoric rise as an insult. A major secondary conflict involves the strict school faculty, particularly the exasperated teacher Muku, who desperately tries to steer the boys back onto the straight and narrow, usually resulting in comedic disaster. Meanwhile, the romantic and
social dynamics shift with the introduction of Kyoko Hayakawa, a formidable female delinquent from a girls' high school who is secretly in love with the chivalrous Ito, and Riko Akasaka, the fiercely athletic daughter of a dojo master who frequently keeps Mitsuhashi in check despite his persistent, annoying flirtations.Throughout the series, Mitsuhashi and Ito balance the mundane struggles of teenage life with high-stakes street brawls. Their motivations evolve from a superficial desire for coolness and intimidation to a genuine brotherhood and a protective instinct for their friends and schoolmates. Ultimately, the duo cement their legendary status in the local delinquent underworld, proving that their bizarre partnership is unbreakable even when faced with overwhelming odds, massive gang wars, and the everyday chaos of 1980s Japanese
youth culture.
