Then when he was in high school, he was surrounded by Makoto, Rin, and his other friends, and after coming into contact with them, he decided to keep swimming and aim for the world championships.

Makoto Tachibana

Makoto is Haru’s childhood friend and best friend. When they were young, he saw Haruka’s potential and invited him to join the swimming club together. They have a relationship where even if words are not exchanged, they are able to understand each other. Up until now, Makoto has been the type of person to frequently look out for those around him, but now that he is in college, he is studying how to work towards a goal he has found for himself. He is looking to be involved with swimming in a different way compared to Haruka and the others.

Rin Matsuoka

Voice Actor: Mamoru Miyano

Rin tried his hand at studying abroad for swimming in Australia when he was a child. But when he was in high school, he swam in a race against Haruka and others and rediscovered his love of swimming. Rin and Haruka mutually acknowledge each other and are rivals that trust one another. After graduating, Rin moved back to Australia and continue to practice swimming in order to make his dream come true of standing on the national stage. He is a member of a swimming team where players from all over the world have gathered, and it is there that he has a stimulating encounter.

Ikuya Kirishima

Voice Actor: Kouki Uchiyama

Ikuya was a member of the relay team at Iwatobi middle school where Haruka, Makoto, and Asahi all attended. He’s rather inexpressive and this has caused issues around him, but after swimming in the relay race with Haruka and others, he realized how important friends are. In the spring of his second year in middle school, he went to study swimming abroad with his older brother and temporarily left Japan. After coming back though, Ikuya participated in an individual medley and his freestyle resembles that of Haruka’s.

Asahi Shiina

Voice Actor: Toshiyuki Toyonaga

When Asahi was young, he was moving all over the country due to family circumstances and met Haruka when he was a first-year middle school student. He swam freestyle with Haruka. Asahi hates to lose and swears that he is going to beat Haruka in freestyle swimming one day. He always has a cheerfulness about him always building a team no matter where is his, and for that reason, no matter where he goes, he treasures those he meets. He continues to swim after graduating high school and reconnects with his past friends in a chance encounter.

Hiyori Tono

Voice Actor: Ryouhei Kimura

Hiyori is from Shionezaki High School where Ikuya is from and they both belonged to the swimming team there. There is just something about Ikuya that interests Hiyori and so the two are found together often. Hiyori is well-versed in swimming athlete information and it appears that he is quite interested in Haruka. After graduating high school, he continues swimming with Ikuya at the same university. He greets anyone and everyone with a gentle smile and is polite, but he very rarely reveals his true feelings.

Sousuke Yamazaki

Voice Actor: Yoshimasa Hosoya

Sousuke has been Rin’s best friend since they were in elementary school and they both understand each other well. His swimming style of choice was the butterfly stroke, but he injured his shoulder. Ever since his final match in high school, he has walked away from swimming. After graduating high school, he helped out with his family’s business and would sometimes visit the Samezuka Academy swimming team. As a graduate, he was respected by the team there. Giving accurate and direct advice, his juniors began to rely on him.

Natsuya Kirishima

Voice Actor: Kenji Nojima

Natsuya is Ikuya’s older brother. His stance towards swimming had a massive influence on Ikuya. When Haruka joined the Iwatobi Middle School’s swimming team, Natsuya was the current acting club president. He easily gets worked up over winning or losing meaning he has an emotional personality. Due to having competed in actual competitions overseas, he has real talent for swimming competitions. Even now, he keeps in contact with his best friend Nao.
