The plot focuses on Ayasaki Hayate a hard working highschooler wo's parents are deadbeat gamblers. As such he gets lumped with a $1 million debt that he can't rpay. Purely by chance he encounters a young girl and saves her from kidnappers. This girl turns out to be Sanzenin Nagi a very, very wealth young girl. this girl subsequently falls for hayate and agrees to pay off his debt i he works for her as her new butler. Thus much hilarity ensues.
This is a very funny show and the whole thing works very well but it isn't as good as it could have been. To be honest I think some of the problem is that a lot of the pun's are lost in translation which means that sometime whole episodes are either not funny or make no sense. But it is still worth watching and still better than most of the comedy animes out there.
