Siren

Siren, prince of the Sharks and one of the main protagonists in Castle Swimmer

**Siren** is the prince of the Sharks and one of the protagonists of *Castle Swimmer*. He was supposed to kill Kappa as part of a prophecy but chooses to save him instead. He is currently on a journey to find his Father, and to find a way to break the Sharks' curse.

## Personality

Siren is a calm, diplomatic person with strong morals. He often tries to help others, and feels immense guilt when unable to help others who are in pain, leading to him sometimes lacking confidence in himself due to feeling "useless" to his people. He also seems somewhat introverted, since he usually eats alone and repeatedly tries to avoid crowds.

## Appearance

A close up of Siren's face, showing off his scarsAn early season 2 upper body of SirenSiren has icy blue eyes, icy blue "frogfish" hair, according to Kappa, and a shark tail. He seems to be very tall, in comparison to Kappa and has a slim but fit build. His skin is rough. He often wears silver jewelry, specifically fashioned for him as prince of the Sharks, though he doesn't like it. Later on he removes his jewelry and gains a scar across his back due to Susca accidentally slashing him with a spear when attempting to kill Kappa.

During Episode 54, Siren has a small chunk of his caudal fin eaten by a sand eel. Later, during Episode 77, he gains two scars across the left side of his face and loses a chunk out of his ear.

## History

Siren had first learned about the prophecy at the age of 6, and was always so excited about it. Around that age, his father left the Castle of Sharks to look for a way to fulfill The Prophecy, murder-free. However, his father never returned.

## Story

Siren makes his debut in Episode 2, where he is speaking with his mother, Susca, and Selkie, when a guard alerts Susca that the Beacon had arrived. Siren is surprised by this news, as he does not want to kill The Beacon. When he gets sent off to the dungeons, where the Beacon, Kappa, is, he's overcome with dread and confesses that he really doesn't want to kill Kappa. Deciding not to kill Kappa since it is the right thing to do, Siren then has to tell the others what has not happened and gives the excuse that god told him not to.

Throughout Episode 2 to about half of Episode 11, Siren contemplates Kappa being imprisoned and heads to speak to him. They enjoy chatting with each other for eight days, as shown by Kappa marking the walls of his dungeon cell with a stone. Siren finds that Kappa understands how he himself feels about it not being possible to live up to others expectations, and assumes he can read minds. He has already thought of an escape plan which involves him finding the key and drawing everyone's attention for Kappa to simply swim away.

Siren enjoys the days spent speaking to Kappa about prophecies he has fulfilled, to comparing the textures of their skin, whilst he gives daily excuses on why he is unable to fulfill his prophecy.

Halfway through Episode 11, Siren is shown assisting his mother with creating a mural of their prophecy, continued into Episode 12, until his mother smells blood. Siren and Susca are then notified by guards that the kingdom is under attack by a band of barracudas. Susca leaves to fight and puts Siren under the protection of Skiff and Seko.

With barracudas finding them, Siren can only remain fixed to the spot with fear even after his guards tell him to escape and he is only saved with his mother's arrival. Siren visits those who had sustained injuries in the fight before making his way to speak with Silver.
With the pressure still remaining to kill Kappa, Siren takes advantage of the rare opportunity of friendly visitors in Queen Nee and Queen Krilli and thinks to give them a tour of the kingdom. Distancing himself from the guards his mother has sent after him, Siren is sure to bring both queens to the armory, pointing out the key to the beacon's jail cell as he does so. Next, Siren suggests heading to the dungeon itself and has to explain to Queen Nee and Queen Krilli that he has not been duped, he needs them both to break Kappa free and escape with him.
Imprisoned by his mother, he implores Selkie for help and after following her advice to listen to the bubbles, he calms himself to notice the key to his cell nearby. He swims and even bites a guard to ensure that he can reach Kappa in time, and endures the spear meant to kill Kappa.

## Relationships

### Kappa - Boyfriend

When Siren first met--or *saw*--Kappa he seemed to be very amazed, mainly by the fact Kappa had beautiful golden scales. Siren appears to be very flustered around Kappa, perhaps meaning Siren has a crush on him. This is confirmed in Episode 41 of Season 1 when Kappa tries to kiss Siren.
It was Siren's destiny to kill Kappa and even though he was told Kappa as the beacon wanted to die, and seeing that Kappa was ready to do so, Siren instead decided to save him. Addressing him as "Mr. Beacon", Siren was courteous and spoke with him as he worked on his escape. Enjoying their time they spent together, Siren wanted to save Kappa even if it was the last thing he ever does.
Siren tells others that Kappa had really pretty eyes.

### Susca - Mother

Susca is Siren's mother, and the two have a close relationship. Susca is a very doting mother. When Siren failed to kill the Beacon, she wasn't upset or angered, but calmly asked him if he was ever going to kill the Beacon. She put up with his lies about not being able to kill the Beacon very well.
Susca seems to be very gentle with her son despite his repeated inability, and never gets angry with him. Instead, she understands why he is so upset, claiming his morality stands in the way of his ability to achieve The Prophecy.
Though after trying to kill Kappa with the ceremonial spear, which ultimately ended with Siren being slashed with it, Susca's secret about the prophecy is revealed, as she was shown to have altered it to keep her son safe. She was stripped of her title as Queen.

### Skiff - Guard

A guardsman who Siren has known since childhood, and who he wanted to help him escape the kingdom. He accuses Skiff of not trusting him when he blocks his and Kappa's escape route out of concern for his safety. Addressing his fighting and leadership abilities, also that he is dedicated to keeping everyone safe, Siren asks if Skiff would become the new king.
