Nagisa Hazuki (葉月 渚 Hazuki Nagisa) is a main character of the anime series Free!, beginning with Free!, and the light novel High☆Speed! written by Kouji Ohji. [4] He is the breaststroke swimmer for the Iwatobi High School Swim Club as a third-year high school student at Iwatobi High School. Following high school graduation, he attends Naribusawa University where he is a member of their swim team.


Nagisa Full

Nagisa is a young man of average build with wavy, honey-blond hair and magenta eyes. His fall and winter school uniform consists of light brown trousers, a white shirt with red necktie, tan sweater, dark gray unbuttoned blazer, and black shoes. During the spring and summer, his uniform consists of gray trousers, a white shirt with a dark gray collar, a tan sweater vest, red dotted necktie and white shoes. His uniform as a 3rd-year changes only in the color of his necktie being green. In the beginning of the series, he is seen wearing red swim jammers with a yellow star pattern;[5] however, he later switches to black swim jammers with a pink pattern. The most developed muscles of his form are his soleus muscles.


He has a cheerful and straight-forward personality. He is very opinionated and usually speaks his mind before considering the effect it may have on others, though never with malinintent. It was this attitude and his enthusiasm for swimming that established the current Iwatobi High School Swim Club in the first place, after a long lapse.[1] He can get very enthusiastic about things that catch his eye and if there is something that even remotely interests him, he will instantly act upon and pursue those feelings.

Nagisa has admired Haruka Nanase's swimming style since elementary school, enrolling at Iwatobi High School in the hopes of swimming with his former teammates, as he previously attended junior high away from Haruka and Makoto Tachibana.[1] He can be quite pushy in achieving his goals, especially when Haruka doesn't share an opinion with him; however, this often pushes Makoto to assist.[1][6] Nagisa also lacks some manners as he frequently speaks with his mouth full of food and a tendency to be noisy and untidy.[7]

Nagisa also has a certain rebellious side, as seen when he insisted on sneaking into the indoor swimming pool of Samezuka Academy, which was closed at the time, committing trespass.[1] He often behaves in a childish manner and seems to lack inhibitions, as seen when he goes skinny-dipping in Samezuka's pool and does other things most people would find embarrassing.[1] He is shown to be sly in having his needs met and stubborn, especially when it comes to Gou Matsuoka's name, for no matter how hard Gou tries to make him call her "Kou" (which she considers more feminine), he insists on calling her "Gou", much to her dismay.[1][8][5] Although he tries to be helpful to his friends, his solutions to problems are often unconventional and usually to his benefit. He is particularly close with Rei Ryugazaki, though he gets along well with everyone in the series and has many friends.


When Haruka and Makoto begin attending Iwatobi Junior High School, Nagisa is left behind at Iwatobi Elementary School. Because of this, he goes to swimming practices at Iwatobi Swimming Club alone.

When Nagisa starts practicing butterfly with Rin Matsuoka, his breaststroke evolves into the butterfly. He also wants to evolve the butterfly even further and to be able to swim all strokes, like Rin, in order to swim in an Individual Medley. Since his first appearance in a tournament was as a team member with Haruka, Makoto and Rin, he feels uneasy at the thought of swimming alone.

Also, it is revealed that while still an elementary school student, Nagisa's three older sisters often dress him up in girls' clothing and put makeup on him. One day, when they switch their swimsuits with his, Haruka offers to lend him a swimsuit and take his sister's. Ever since, Nagisa has greatly admired Haruka, however, the bullying by Nagisa's sisters continues into high school and, time after time, they switch his swimsuit with theirs.

Creation and Conception

Early sketches of Nagisa.

Hiroko Utsumi said that Nagisa was the cute younger brother type of character. He always acts childish for his age, even though he's not even a year younger than the rest of the group. Nagisa is the only one who physically plays around with Rei, but since it's Nagisa, Rei's good points are brought out. He's the one who is able to bring out everyone's various expressions. His outer appearance also feels childish with his big and round hairstyle. His personality is that of a natural airhead; everything goes over his head. He's the type of person who gets by on instinct. As soon as he thinks of something, he acts on it instantly. Nagisa has a lot of small penguin accessories because he loves big penguins. In the first episode, you can get a glimpse of his underwear which has penguins on it. He enrolled in Iwatobi High School wanting to swim again with Haruka and Makoto, but there was actually another reason - "Iwatobi" in Iwatobi High School means "rockhopper penguin". With that kind of inspiration, he easily made his decision where to apply. Futoshi Nishiya added that "He's a cute character, but as a first year high schooler, his body is a bit tense. He's not just cute and, while he does say some stupid things as he pleases, he's not an idiot. We drew him carefully while examining the rest of the cast to maintain balance among designs." His character is very important to help move the story along.


  • His motif animal is a rockhopper penguin.
  • Like all members of the Iwatobi High School Swimming Club, Nagisa has a feminine name.
  • Nagisa has an extreme sweet tooth. For lunch, he always eats "rock" and "hopping" bread, which is bread with strawberry jam, marmalade, and chocolate on top. It costs ¥480.[9]
  • Nagisa's favorite food is strawberry shortcake, and he prefers to eat his favorite foods first.[2]
  • Nagisa's dislikes are Math, peppers, and onions.[2]
  • Nagisa owns a pink cellphone.[6]
  • Nagisa likes eating strawberry flavored ice cream and strawberry cake.[10]
  • Nagisa's best subject is History, while his worst is Math.[10]
  • Nagisa likes history, all sorts of insects, horror movies and thrill rides.[10]
  • Both Gou and Nagisa's rooms exactly copied from North American furniture catalogs and blogs.[11]
  • Though he eats junk food very frequently, he still gains muscle and his body is fairly toned.
  • Nagisa talks in his sleep.
  • The seiyuu for young Nagisa, Satomi Sato, also voices Chigusa Hanamura.
  • Nagisa used to have a dog when he was a kid. Its name was Dick and it had a white fur.[12]
  • At a staff talk event for Free!–the Final Stroke–, one of the character designers discussed the main characters' body types in terms of musculature. Nagisa was listed as being "type 1:" which is the most basic/lean muscle type amongst the swimmers.[13]
  • Those born under Leo are cheerful, humorous and warm-hearted, but can also be stubborn, self-centered and inflexible. They like fun with friends and being admired, and dislike facing difficult realities and being ignored. Those born on Aug 1 are idealists who follow their gut feelings but must learn not to be pushy. Traits are affected by the position of the moon and other planets at the time of birth.[14]
