三千院 凪-37
Nagi Sanzenin (三千院 ナギ Sanzen'in Nagi) is the sole heir to the Sanzenin fortune, being the only survivor of the family besides her grandfather. She isn't just the average "rich girl". Calling her "rich" would be selling her short. The "Sanzenin fortune" is so large, throwing away 20 trillion yen in a red herring investment is considered a prank. Moreover, Nagi fell for that "prank" when she was a child - she's 13 now, and by far wiser. She doesn't particularly desire the inheritance. However, other people do want that wealth, and will acquire it by any means necessary, leading to many complications for Nagi, the least of which involve kidnappings and attempted assassinations. Hayate, her butler, is indebted to her, so Hayate always save Nagi from any accident, kidnapping, or assassination. Even though Hayate himself attempted to kidnap her for ransom money, Nagi has a crush on Hayate ever since she first met him in the kidnapping situation.


Nagi is short in stature, she has long blond hair which is tied in two long twin tails and she has green eyes which she inherited from her parents. According to Hayate, Nagi looks like her mother. She wears a Hakuo uniform during school, while at home she is usually seen wearing modern clothing.

When she used her alter ego Mask the Money, she wears a mask to cover her eyes and a short frilled skirt with long thigh high socks and a long sleeved blouse with a huge ribbon. During New Years, she wears a yukata with different designs on it. Nagi always wears shoes with heels just to look tall and doesn't want others to call her "short" or "small".

Background and Personality

Nagi is short-tempered, spoiled, anti-social or socially withdrawn, hates to lose and to admit her faults, has a considerably hard time confessing her true feelings towards Hayate (but does confess in the last episode of season 3) or anything in the fact of the matter, she acts immature a large portion of the time but is ultimately a good, educated girl. She is good at finance and likes to learn. Her mind is possessed with her own. She cares for her family and friends, but she doesn't want to show her concern directly. She usually tends to show her concern with "formal words". She is a tomboy and tsundere hikkikomori princess.

Since going outside is very dangerous because of her status, Nagi favors staying at home. Not liking company in general, she lives away from her grandfather in a "small" (compared to the main Sanzenin estate) mansion with minimal staff. Despite her Otaku NEET-like lifestyle, she is intelligent enough to skip 3 grades at school, which even turns out to be one of Tokyo's most prestigious academies. She has an otaku-level hobby with manga, anime and video games, and draws her own manga which is called Millennium Legend: Magical Destroy. Her Otaku-level is high enough that she has submitted entries for multiple amateur manga competitions, though her entries never won. Her art is decent (she started drawing almost from when she was a toddler) but her sense of plot is incomprehensibly warped, not to mention her art style is odd at best. Her genres clash and she draws a magical girl story in the style of a Shonen Manga, Magical Destroy (read: very muscular, very masculine magical girl named Britney who behaves more like a samurai). Only her best friend, Isumi, and a wanderer ghost, Linn Regiostar, can read and understand her manga.

Because of her pampered existence, she lacks any worldly knowledge and is even incapable of looking after herself. In an episode, with the absence of both Maria and Hayate, she was shown to be incapable of even making a cup of tea on her own, wrecking the mansion in the attempt. Nagi is mortally afraid of the dark (due to an incident with Isumi), so she shares her bed with Maria in the nights. She also doesn't like swimming. While Hayate always reminded her to go outside and gather experiences on the outside world, she always thought that that will be boring or she always lost and risk being kidnapped. Which Maria always states to her that without Hayate she will always get lost or be in danger.

Nagi likes to do what she likes to do, but mostly what she likes to do is not so good for her future. She is so hard to control, that even Maria, who has lots of talents, can't control her. But Hayate, her average educated and insensitive butler, who saved her from the kidnappers and the mafia, is able to convince her to go to school, do exercise, have many friends, etc. He helps Nagi to be a better person. He saved both her life and her lifestyle. In short, Hayate is her savior.

Sakuya Aizawa is Nagi's cousin. Sakuya is a talkative, cheerful girl. Her first encounter with Nagi was on a party when Nagi was about 4–6 years old. Sakuya saw Nagi was gloom, so she decided to talk to her. Isumi Saginomiya is Nagi's best friend. Probably she is her best friend. Isumi is a quiet girl, who easily gets embarrassed. She met Nagi on party that held because Yukariko's health became better when Nagi was about 5–6 years old. Nagi showed Sakuya her manga and got insulted by her. Nagi threw her manga to a trash bin. She cried and decided to stop drawing manga. But Isumi picked it up, read it and was interested. She asked Nagi for the next chapter. Nagi was touched. Wataru Tachibana is Nagi's friend and fiancé. Wataru is a blunt, responsible kid. He owned a DVD rental in the middle of Tokyo. His first encounter with Nagi hasn't been explained. He had many fights and argumentations with Nagi.
