Kankichi Ryoutsu 両津勘吉

"Ryo-san" is a thirty-six-year-old police officer with the personality of a twelve-year-old. His laziness when it comes to work is matched only by his zeal and cleverness in hatching money-making schemes, the fruits of which are invariably squandered on toys, gadgets, and cheap entertainment. He is the stereotypical street-smart "shitamachi" type, sporting a Crew cut and stomping about in ratty sandals (even in uniform), and narrow-minded towards the outside world, as he makes his rounds on a creaky old bicycle. At the same time, he is a super-otaku, up on all the latest fads in popular culture and consumer technology.

While most of his interests are of the juvenile sort (such as video games and collectibles), he also indulges in more typically salaryman-type pastimes such as drinking, pachinko, and gambling (especially horse-racing). Despite his undisciplined lifestyle, he possesses superhuman strength and stamina, which he is forced to depend on at times. Ryotsu is a bachelor and seems relatively uninterested in women, yet occasionally attracts the attention of naïve young female acquaintances, though never with any eventual success.
