Hiyori Tono

Hiyori Tono (遠野 日和 Toono Hiyori) is a main characters in the anime series Free! beginning with Free!-Dive to the Future-. He is Ikuya Kirishima's roommate at Shionezaki High School and later attends Shimogami University with him. He is Ikuya's top supporter, other than Ikuya's older brother, Natsuya Kirishima. He is a skilled backstroke swimmer.

Appearance
Hiyori is a tall, muscular young man with hazel eyes and short, auburn hair. He wears corrective lenses.

Personality
He has an overprotective nature when it comes to Ikuya, but is generally upbeat and supportive when with him. However, when addressing Ikuya's former junior high swim team members, he is brash and outspoken, though his barbs are often said in a calm manner and with a disarming smile. Over the course of season 3, Hiyori comes to terms with his negative feelings and becomes friends with Haruka Nanase, Makoto Tachibana, Asahi Shiina and Kisumi Shigino.

History
When Hiyori is very young, he is often left on his own while his parents are at work. Being shy, he didn't approach others and one of the few people who spoke to him was a girl named Tomo while he is playing in the sandbox. Kaede Kinjou also approaches him and maintains an unsettled relationship with him.

Hiyori later goes to the United States attending high school and becomes friends with Ikuya. He currently attends university with Ikuya, and they are teammates in the Shimogami Swim Club. When Ikuya's older brother, Natsuya, begins traveling as a professional swimmer, he tasks Hiyori with looking after Ikuya, whose health is fragile. Hiyori takes this responsibility seriously and protects Ikuya in every way possible from both physical and emotional upset. He considers Ikuya's former teammates from the Iwatobi Junior High School Swim Club to be unworthy "weaklings" who can not compare to Ikuya's swimming genius. Thus, he has no problem being abrupt with Haruka, Makoto and Asahi, forbidding them to see Ikuya despite their genuine desire to make amends for their past disbanding of the junior high team without an explanation.

At one point, Haruka bets that if he can beat Hiyori in a swimming race, he must allow them to meet with Ikuya. Hiyori agrees, however, Makoto races in Haruka's place since Hiyori and he are both backstroke experts. Hiyori wins the race and although the former teammates assume Hiyori will relent, he does not and, in fact, Hiyori insults Haruka saying, "everyone who swims with you suffers."

Eventually, each one of Ikuya's past friends find a way to make amends with him and Ikuya realizes his folly in keeping himself closed off from everyone. He apologizes to Hiyori, acknowledging their friendship and asking to swim with him as a member of their university's relay team. Finally, at the All-Japan Invitational, Ikuya and Natsuya reunite and face-off in a race with Ikuya winning and Natsuya congratulating him, their sibling relationship restored to a healthy balance. Natsuya also apologizes to Hiyori for burdening him unduly with Ikuya's care. With the burden removed from the young swimmer, Hiyori relaxes and feels comfortable allowing Ikuya to spend time with his former friends, coming to spend time with them, as well.
