Haruka Nanase (七瀬 遙 Nanase Haruka) is the main protagonist of the anime series Free!, beginning with Free!, and the light novel High☆Speed！ written by Kouji Ohji.  He is a freestyle swimmer and was vice-captain of the Iwatobi High School Swim Club. He is currently a university student at Hidaka University where he also a member of the swim club while pursuing professional competition on the global stage.
Haruka is a muscular young man with blue eyes and short, straight black hair with bangs that dip between his eyes. He maintains a serious expression and rarely expresses emotion. In high school, he often wears his jammers beneath his regular clothing in order to be ready to swim on a moment's notice. As pointed out by members of his swim team, all of his jammers are nearly identical (black with minor variations in the violet striping), yet he claims they all fit differently, and he often has trouble selecting which one to wear in the morning. The most developed muscles of his form are his tricep and abdominal muscles (upper arms and abdomen).
His autumn and winter high school uniform consists of brown trousers, a long-sleeved white shirt with a green necktie, dark gray blazer, and blue sneakers. During the spring and summer, he wears gray trousers, a short-sleeved white shirt with a dark gray collar, a green dotted necktie, and blue sneakers. When not in school, Haru dresses in stylish, casual clothes suited for his age.
He is a quiet but determined individual with a strong affinity for water. His greatest asset is his confidence in his decisions, once made. Despite his cool persona, which many perceive as uncaring, he is protective towards his friends, particularly those on his high school swim team: Makoto Tachibana, Nagisa Hazuki and Rei Ryugazaki, but particularly Makoto, his best friend since childhood. This is seen twice during the team's seaside summer training -- first, when Haruka rescues him from nearly drowning and second, when the group is back on shore and sharing stories. Makoto tells his team the truth about his thallasophobia despite Haruka's attempts to protect him by stopping his telling the story.
Haruka also values his relationship with Rin Matsuoka, another childhood friend with whom he shares an intense athletic rivalry. During elementary school, while on break from schooling in Australia, Rin loses to Haruka in a private race and declares he is quitting swimming altogether. Though Rin's reasons are otherwise, Haruka believes it is his fault and, out of guilt, quits competitive swimming. When Rin returns for high schooling in Japan, an impromptu race restores both of their competitive spirits and both join their respective school teams. Later, at the tournament, Rin is released from his school's relay team and runs off. Haruka seeks him out and reminds him that it was Rin who taught him that the most important thing about swimming is not winning, but teamwork with friends. Rin takes Rei's place in the relay race and although the Iwatobi team's win is rescinded, everyone's friendships are restored.
Haruka's fixation with water sometimes makes him a comical figure as he often wears his jammers beneath his clothing and will strip down to his jammers just about anywhere if there's available water nearby (including a fish tank). He even considers an encounter with a waterfall to be romantic. Despite being stoic, he is ticklish, as seen in the FrFr short, A Distant Tremble!
Haruka has been friends with Makoto since early childhood, meeting him on a local playground in Iwatobi. As the playing children run to see a passing rabbit, Makoto trips and falls but is helped up by Haruka who sees his distress. Since that time, the proximity of their homes and complementary personalities grows their friendship. One day, Makoto asks Haruka to join the local Iwatobi Swimming Club with him, but Haruka refuses saying, "it's too much trouble." When Makoto replies he will not join either, Haruka asks why and Makoto says there's no point if Haruka isn't with him. Haruka eventually does join and others begin to see his incredible talent. 
While attending elementary school, Haruka teams up with Makoto, Nagisa and Rin to form a relay team that wins a tournament.
At Iwatobi Junior High School, Haruka does not intend to join clubs because it will detract from his swimming time. On the first day of school, classmate Asahi Shiina approaches saying, "You look like the type of guy with no friends,." getting off on the wrong foot with him, though he fails to realize it. Haruka does not want Asahi to call him "Haru" like Makoto, but says he can because he wants the boy to stop following him around. Haruka is eventually drafted into the Iwatobi Junior High School Swim Club, along with Makoto, Asahi and Ikuya Kirishima. Later in the school year, when Makoto creates distance between them, Haruka is the one to reach out and initiate amends. He also makes a pinky promise with Ikuya that they will one day swim a race against one another. Their team, however, falls apart when Asahi moves away and Haru quits competitive swimming (causing Makoto to also quit), hurting Ikuya deeply.

Creation and Conception
Hiroko Utsumi, the director of seasons 1 and 2 of the anime, describes Haruka as "equipped with 'coolness'." "One aspect of him is his love for water. He has a bit of an eccentric image; he has trouble interacting with people at a fundamental level. If he's not interested in something, he won't do it. Normally his facial expression is very unsociable, but he gets highly emotional when it comes to water. He's a direct boy who has a strong obsession with the freedom that water gives him." She adds that the audience will get to see Haruka graduall[y change as he matures throughout the series, as seen in episode nine.
The animators had little trouble designing Haruka's character, paying special attention to his eyes, made blue to reflect his love of water. On close-ups of his eyes, the animators have made them detailed, using many frames to make them life-like. Character designer Futoshi Nishiya dresses Haruka with clothing for easy removal because whenever he sees water, he wants to swim in it. The designer also says that when he designed school uniforms for the Iwatobi High School students, they fit perfectly on everyone except Haruka, shocking the crew.
The animators named Haruka a "waterdere," because water brings out his emotions, which nothing else can do. "Sometimes it's obvious that he loves water by how much his eyes sparkle when he sees it. Those kinds of actions and glances speak as much as words to help bring out that humanity in him," Utsumi explains in one interview.

Traits are affected by the position of the moon and other planets at the time of birth.
