Ryōta Takao, a reformed biker turned bus driver, now navigates the streets behind a steering wheel instead of handlebars. His undefeated streak in brawls cements his fearless reputation, particularly when confronting roughneck rivals from his past. Behind the wheel, he drives with reckless abandon, prioritizing personal vendettas over passenger safety—street-racing rivals, ramming hostile vehicles, and shrugging off collateral damage. Authorities turn a blind eye, as his chaos disproportionately targets those labeled societal threats.

A paradoxical mix of lechery and loyalty, he treads moral gray areas with a roguish grin yet intervenes decisively in crises. This contradiction peaks when he abandons self-interest to rescue a kidnapped love interest, weaponizing his usual recklessness against her captors. His chaotic dynamic with an equally unscrupulous comrade fuels volatile misadventures, marked by mutual mockery and underhanded antics.

Though his origins remain shrouded, his history of street-racing clashes and defiance against authority lingers. Across episodic escapades, he embodies a chaotic enigma—self-serving yet sporadically noble, thriving in the absurdity of his comedic, collision-prone world.
