Hayate is one of Lisa's attendants. While he only makes a handful of appearances in the manga, Hayate in the anime forms a strong rivalry/friendship with Tomoka, and the two occasionally battle one another in friendly duels. Hayate is a very calm, loyal, and serious individual who will go to great lengths for his mistress, Lisa; this usually involves doing some sort of research or private investigating. Tomoka nicknames him "ninja" because of his stealthy ways, only revealing himself when attending to Lisa, or to attack.
