One of four childhood friends from Shioshishio. He is Hikari's best friend who is quiet and mature for his age. He is interested in Chisaki and cares deeply for her. During the Ofunehiki festival, he goes into hibernation after falling off the boat while helping Chisaki save Tsumugu Kihara. After the time skip, similarly with Hikari, Kaname wakes up without having aged and is staying at the Kihara family's home. While being the mature of the group, Kaname has always felt left out. He realizes that when Chisaki's feelings for Hikari are just what she has been convincing herself to feel this entire time, when really a while after Tsumugu and Chisaki met, she actually have feelings for Tsumugu. She didn't even realise this herself - causing her to keep lying to herself that she's in love with Hikari, when really Kaname has known that even 5 years ago, it was always going to be Tsumugu.
Kaname has long, beige hair. Just like the other people from the sea, his eyes are blue.
Kaname is usually seen in his uniform. He is said to be handsome, as shown by Sayu and Miuna's female classmates comments on him.
Kaname is a relatively laid back person who prefers to take things easy and as they come. Generally preferring to avoid unnecessary conflict, Kaname occasionally complains when Hikari ends up determined to do something and proceeds aggressively. He rarely shows his true feelings to others.
On their first day of going to school on the surface, Kaname walks with Chisaki and Manaka and greets Hikari just as he arrives and runs past him. As he berates Manaka for wearing the uniform of the surface school rather than that of their underwater school, Kaname complains of him making a fuss as she leaves to change. Kaname proceeds with the others to the surface and though Hikari says he will not wait for her, he does so regardless, leaving Kaname and Chisaki to go on. Soon, Manaka does not turn up and is found to have been caught up by mistake in the net of a fishing trawler, a scene at which Kaname looks upon in surprise.
At school, Kaname takes part in introductions before taking part in running track. The morning, before school, Kaname and the group arrive to pick up Manaka from her house but find that she refuses to come out, forcing Hikari to go get her. Later at the end of the day, Manaka runs away from school, forcing Kaname and the group to go looking for her.
Looking through the city, Kaname and the group come to the conclusion that Manaka did not return home. As they notice their skin beginning to crack from sun exposure, the three take refuge in the water temporarily, before Hikari leaves to continue the search alone. As Chisaki begins worrying about him, Kaname comments that she and Hikari look like parents to Manaka and tells her if anything happens to Manaka, she will be next to his side. This upsets Chisaki as she tells him that he's not funny, to which he apologizes and admits that things are hard for them.
Sayu has had feelings for Kaname after he got her to open up about her past and befriend Hikari Sakishima and it still remains even when she got older. She was always watching over him and he was always in her heart. She tries to move on, but Kaname was the only reason for moving on with her life. She tells Kaname that it's selfish to not love, and so she tells Miuna Shiodome that she is going to tell him how she feels about him. After Kaname was eavesdropping the conversation between Tsumugu and Chisaki, he walks away and she runs after him. She confesses her feelings for him and she tells him she was waiting specifically for him and that he was always in her heart, which surprises him. After Sayu confessing to him, Kaname cries in joy, because he thought no one was waiting for him after the Ofunehiki and starts to look at Sayu at her own age and gives her a chance, since she is now the same age as him. During the second Ofunehiki, Kaname saves Sayu from falling off the boat instead of following Chisaki - telling us that he is choosing Sayu over her now.
In the last episode, it is implied that Kaname and Sayu have grown closer and the will be together in the future. Sayu approaches Kaname and Kaname smiles at her.
Kaname is known for always being there to protect Chisaki as he would always be the only one there to cheer her up if there is any incident or problem. Later on in the story, pressured by the upcoming hibernation, Kaname appears at Chisaki's door which is where he confessed his feelings for her. After hearing the news, he had realized that her parents were listening, and tells them that he just confessed his feelings to their daughter. Afterwards, things tend to be awkward as Chisaki does not know how to reply or react, but instead decides to tell Hikari how she feels about him because of his confession. However, he prevents her from admitting her feelings by asking Hikari how he really feels about Manaka, causing Hikari to admit that he loves Manaka and not her, which causes a strain in their friendship, but later she understands why he did what he did.
During the maiden sacrifice, Chisaki and Kaname dove into the ocean to save the drowning Tsumugu, after the large wave from the sea god caused his boat to flip over. Chisaki and Tsumugu managed to get back onto a nearby boat, but just as Kaname was climbing onto the railing, he was shocked to see Chisaki embracing and sobbing over an unconscious Tsumugu. His brief moment of shock caused him to lose his balance on the rail due to the boat making a sharp turn to avoid a nearby falling pillar, and Chisaki could only watch Kaname as he fell back into the sea while Kaname gave her one last smile just before he disappeared. After the time-skip, Kaname awakens to discover that Chisaki had avoided the hibernation, and she is now biologically five years older than him.
After Tsumugu told Chisaki he loved her and she rejected him, Kaname tells her to tell him what she feels to help her feel better and to not worry about his feelings for her. He realizes that when Chisaki was just lying to herself that she still loves Hikari, even after 5 years it would've always been Tsumugu, not him. He helps her move on from Hikari by telling Tsumugu to tell her that Manaka loves Hikari, so she would find closure and move on to Tsumugu. After Sayu tells him that she was waiting specifically for him, Kaname decides to start looking at her and moves on from Chisaki.
Hikari is Kaname's best friend. The two are always together with Chisaki and Manaka. Together, they help protect Manaka from harm. He also helps Hikari to admit his feelings for Manaka, knowing those two were meant to be together, and not Chisaki with Hikari.
Tsumugu and Kaname are friends, but Kaname begins to not like him very much after he shows closeness with Chisaki Hiradaira. This worsens after Chisaki saves Tsumugu at the Ofunehiki, and after that holds him, ignoring Kaname who actually needed her help. After the timeskip, Kaname wakes up and he ends up living with him and Chisaki. Later on, Tsumugu confesses that he likes Chisaki and won't let Kaname take her away and Kaname admits he could've left him to die so he could have Chisaki, but chose to save him for her sake. Nevertheless, he helps Tsumugu by telling the truth about Manaka loving Hikari, so she can move past her feelings for Hikari and so that Tsumugu and Chisaki can be together while he moves on with his own feelings.
