Tsumugu Kihara ( () (はら) (つむぐ) Kihara Tsumugu?) is one of the main characters of the series.

A boy from the surface and the grandson of Isamu Kihara (a fisherman). One day, he meets Manaka Mukaido when she is caught in his net. He is quiet, stoic, and very interested in the underwater world. His grandfather was from the sea. Tsumugu has a complicated relationship with his mother. After the time skip, he attends college and majors in oceanography. He lives in the city and conducts research about the sea villages at his university. He becomes close to Chisaki Hiradaira and he eventually falls in love with her. After accidentally claiming his love for Chisaki, he follows her into the sea and gains Ena. It is later revealed that he had known of Manaka's feelings for Hikari Sakishima since the eve of the Ofunehiki five years previously, but agreed to keep it a secret at Manaka's request. After having a talk with Kaname about Chisaki's true feelings, Chisaki finally accepts her love for Tsumugu and they become a couple. He is last seen walking to the train station with Chisaki as he leaves for college. He is not very good at expressing himself and others therefore conciders him emo. He constantly got bullied as a kid because of his fishing addiction and therefore only shares his intrests with those he is close too. He adores the sea but doesn't have ena. He doesnt know about his grandmother (uroko).

Appearance[]

Tsumugu is a handsome young man with long dark brown hair that goes down to his chin with bangs swept to the left side and puce-colored eyes that are rather emotionless.

He is often seen with his school clothes.

After the Timeskip[]

After the timeskip, Tsumugu wears a casual outfit comprised of a red sweater on top of a black shirt paired with black jeans and blue shoes.

Personality[]

Tsumugu has a very calm demeanor who can even be seen as stoicas he rarely shows emotions on his face and instead, can be seen as blunt when speaking to someone. He is very intuitive though and mature for his age. He's soft spoken and understanding, preferring to listen rather than speak, often acting as a secret-bearer for Chisaki Hiradaira and Manaka Mukaido, although he stopped after the post-timeskip as Chisaki herself did not realize that she was in fact in love with Tsumugu, and before the timeskip Tsumugu had nothing to hide from Chisaki either, like his feelings. He also mentions to Miuna Shiodome that he was envious of Hikari Sakishima and the others because of their ability to express their feelings easily. This means that Tsumugu himself wishes he could express his feelings more (which can be a slightly mild form of alexithymia) but Miuna says that sometimes she wished she could hide them.

History[]

Tsumugu came to live with his grandfather when he left the city at the age of nine. He reveals to Chisaki Hiradaira that his parents disliked the sea, and therefore abandoned his grandfather. He seems to have an uncomfortable relationship with his mother, as seen when he uses his friends to avoid just talking to her. He has a close relationship with his grandfather. He once gave his grandfather fish scales as a present and even though his grandfather did not understand the significance of the fish scales, his acceptance of them made Tsumugu happy.

Plot[]

Manaka caught in Tsumugu's net.

On the morning of the sea kids' first day at Tsumugu's surface school, Manaka Mukaido is berated by Hikari Sakishima for wearing the uniform of her new school rather than their old one and decides to return home and change while her friends go on. After changing, Manaka returns to the meeting spot only to be fished up by Tsumugu and his grandfather.

During P.E., Hikari races Tsumugu. Tsumugu, who had been running further ahead of everyone is oblivious to Hikari. However, while running, Hikari loses his balance and falls onto Tsumugu, taking both of them down.

The next day, as a group of girls take Manaka into the sun to inspect her supposedly shining skin, Tsumugu comes in, questioning the other girls about what they were doing. Manaka, flustered and embarrassed, makes a run for it. Tsumugu is left behind.

Tsumugu looking after Manaka.

Tsumugu, unaware that the other sea kids have been looking for the missing Manaka, finds her unconscious on the forest floor. Knowing about the sea peoples' need for salt water, he brings her home. As he enters his home, his grandfather told him to put her in the bathtub. As Manaka awakens, Tsumugu is seen putting salt into her bath water. Manaka is shocked to see Tsumugu looking after her. Noticing her knee, Manaka asks him not to look, believing it grosses people out. Despite this, Tsumugu attempts to feed it, but is stopped by Manaka. When she continues to be embarrassed, he tells her that the fish was beautiful, the scales on it unique. He then adds that Manaka is also beautiful, complimenting her Ena.

That night, Manaka is taken by Tsumugu back to the water, where she spots Hikari searching for her. As Hikari attacks Tsumugu, Manaka breaks the two of them apart, telling Hikari that Tsumugu helped her. With the boys not fighting, Manaka and Hikari return to the sea, with Manaka looking after Tsumugu's retreating form.

Relationship[]

Chisaki Hiradaira[]

Before the time skip, Tsumugu had a rather complicated relationship with Chisaki. Tsumugu had known that Chisaki had a crush on Hikari, giving his own advice on ways of dealing with it. Often, they were at a standstill with a strained relationship but it had softened over from the timeskip. After the timeskip, Tsumugu confessed to Kaname that he has feelings for Chisaki, but hadn't acted on those feelings until the remaining sea friends wake up so they can both move on, but it is revealed he was scared of them waking up because he thought he would lose Chisaki to them.

Later, when Hikari then tries to force Tsumugu to pretend to love Manaka for the sake of getting her ability to fall in love back, he then tells Hikari that he can't force the feelings that are not real and reveals that he is actually in love with Chisaki, which surprises him and Chisaki happens to be near by. Shocked, Chisaki dives into the sea, where Tsumugu follows her and after believing he would die, he receives ena and follows Chisaki's trail to Shioshishio to talk to her. He tells her that she was always so quiet and calm, and yet sometimes she became so fierce that he couldn't handle her, just like the sea. Tsumugu tells Chisaki that the five years that they spent together, he was always watching her. He always was able to tell when she got angry, laughed, or cried and realizes that her feelings are for him now.

Tsumugu then hugs Chisaki, but she breaks from his hug saying that she doesn't love him back, but after Tsumugu finds out the reason Chisaki rejected him was that she thought Manaka liked Tsumugu and that she's still in love with Hikari, he confronts her about this and states that Manaka's actually in love with Hikari. This shocks her, calling herself "awful", as she feels responsible for getting in between Hikari and Manaka, when in truth, she wanted them to be in love with each other, but also didn't want their friendship to change, while she officially moves on from her feelings for Hikari. Tsumugu tells her that's no longer the case and that the real reason is because she's in love with him and want her to admit it. This causes Chisaki to laugh, whilst Tsumugu tells her he's serious. Chisaki says she knows, and does not try and deny the fact that she loves Tsumugu, now that she knows Manaka loves Hikari. Tsumugu appears slightly shocked that Chisaki is no longer in denial of her feelings, and Tsumugu holds her in his arms, saying he loves her. Chisaki whispers that she can't be the only one who gets to be happy, but does not push him away this time and later she becomes Tsumugu's girlfriend as she has learned to do things for herself once in a while, and find her own happiness.

Manaka Mukaido[]

Tsumugu likes Manaka, but only as a friend. There was no point in time he was ever romantically interested in her, just interested in her Ena and the stories he had heard about the sea. He asked Manaka to confirm many things about it, which Manaka was happily did. Tsumugu often acts as Manaka's confidant, as seen when she tells Tsumugu about her fight with Chisaki. Manaka thought she was in love with Tsumugu but realized she loved Hikari instead. She knows those were the old days, and tells Hikari her true feelings for him. She tells Tsumugu about this, stating that Hikari is the sea. Tsumugu, respecting her feelings and decision, keeps quiet about it, but it is revealed when Manaka's feelings could be heard in the sea as well as the Lady Ojoshi's. However, when Chisaki rejects him because she thought Manaka was in love with him, he is forced to reveal the truth that Manaka was in love with Hikari to clear the misunderstanding between them and that Chisaki would fall in love with him, while allowing Hikari and Manaka to be together without any interference.

Kaname Isaki []

Kaname helped save Tsumugu when he drowned in the sea, but regrets it. When he was drowning, he thought of leaving Tsumugu to die because then he could be with Chisaki, but he saves him anyways and Tsumugu thanks him for that. Even if he didn't save him, he would never let go of Chisaki. After Kaname begins to fall in love with Sayu, he tells Tsumugu the reasons why Chisaki rejected him and helps him to get her to admit that she no longer loves Hikari, but is actually in love with Tsumugu.

Hikari Sakishima[]

At first, Hikari hated Tsumugu since he thought Manaka started having feelings for him after he reeled her in his net. He learns to accept Manaka's feelings for him and they both become friends.
