Hikari Sakishima (先島 光) is the childhood friend of Manaka Mukaido who looks after her and has been doing so since the two of them were young.

Appearance

Hikari is regularly seen in the blue and white uniform of his original school from beneath the sea which was closed down.

Like all people from the sea, Hikari has deep blue eyes while his hair takes on a brownish color.

Personality

At first, Hikari looked down upon people from the surface, viewing them as inferior pigs who threw away what the sea god gave them in exchange for their own greed. As seen with Manaka, he has a great deal of pride for his life in the sea.

However, Hikari soon matures and comes to terms with people from above the sea, soon acknowledging that they are not so different and starting to wish they could work together.

History

When he was young, Hikari's mother passed away. Distraught by this loss, Hikari openly wept at her wake while being comforted by his older sister Akari. Their father has been taking care of them on his own.

Years later, Hikari was told by Akari that she would be working on the surface. Beeing against it, he was told that their family needed the money so he could go to college, and although he claimed he would not, he soon dropped the argument when Akari began crying.

Plot

Hikari pushed away by Chisaki.

Rushing out of his house for his first day of school above the surface, Hikari passes his friends by as he spots Manaka wearing the uniform of their new school rather than their old. Scolding her for attempting to please the surface dwellers, Hikari is told to stop by Chisaki but manages to get Manaka to go home and change. Leaving to go to school with Chisaki and Kaname, Hikari waits at the exit of the ocean for Manaka but she does not show up. Waiting longer, he is surprised to find that she has been caught by the net of a fishing trawler.

At school, Hikari takes part in introductions but quickly gets irritated as the surface dwellers make fun of him and his friends for being from the sea. Arguing and insulting them back, Hikari attempts to get Manaka to do so as well but is unable to as Chisaki stops him once again. During P.E Manaka races Tsumugu Kihara, whose grandfather fished up Manaka that morning. While running, Hikari loses his balance and falls onto Tsumugu, taking both of them down.

Later that day, Hikari meets Akari on his way home and discusses her recent vandal problem. Upon returning underwater, Hikari is spoken to by a mens club who are angry with the surface dwellers recent actions against them. As he recalls the history of people and their origins, he takes his leave and meets with Manaka. Visiting Lord Uroko at the shrine, Hikari witnesses him approach Manaka, causing her to cry and run away and he to curse her as a result.

The next morning, Hikari and his friends head to Manaka's house to pick her up but find that she is refusing to leave. Heading to her bedroom alone, Hikari asks her what the problem is and finds that he kneecap has become a fish head. Knowing that this was the curse Lord Uroko used, Hikari gets angry but quickly sets it aside. As she continues to refuse to go, hoping nobody will see it, Hikari eventually convinces her to go by covering the head up.

However, Hikari comes to find out that Manaka ran away from school and goes out to look for her with Chisaki and Kaname. Despite their efforts, they are unable to locate her and forced to return to the water due to their skin cracking.
