sanzen'in nagi

Main female protagonist of Hayate no Gotoku!

The spoiled, sheltered thirteen-year-old heiress to her family's vast fortune. She hires Ayasaki Hayate as butler after his attempt to kidnap her to escape the yakuza ended up sounding like a confession of love to her. Besides Hayate, she is also friends with her maid Maria, whom she treats as a mother figure.
Owing to her sheltered life (until recently), Nagi is somewhat socially inept, but also has an otaku-level obsession with anime, manga and video games, and is even writing her own doujin. Despite her intelligence (such that she skipped to first-year high school - the same grade as Hayate), Nagi is often too lazy to go to school.
