Jutten!
Yutten! We are talking about a guy who goes on its first high school day, thinking that he will be full of amazing (perverted) meetings with sexy girls and everything else, but instead he was not very lucky, and the dog will urinate him, among other things. The girl who uses his bike to turn his ass, somehow helps him and gives him a handkerchief with a coin at 10 yen (hence the name of the series), and ... after that, very plausible things happen.
