Hayate has had to work to support his parent's bad habits since the age of eight, always moving from job to job, as he is fired when he is discovered to be underage. Hayate's dad is unemployed and his mother is a compulsive gambler, which leads inevitably to their bankruptcy.

The characters in this series continually remark that Hayate looks poor and needy. He believes that everyone hates him, except children, though he doesn't think of children as being anything other than friends. He can also play the violin. Despite his terrible luck, Hayate lives up to the title of "combat butler" as he is proficient in repelling attacks from almost anything, including other butlers.
