Siren (Castle Swimmer)

Siren is the prince of the Sharks and one of the protagonists of Castle Swimmer.

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 anti-social, since he usually eats alone and repeatedly tries to avoid crowds.

Appearance
Siren 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. He often wears silver jewelry. Siren has rough skin, as said in Episode 10.

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 kingdom to look for a way to fulfill The Prophecy, murder-free!

He never came back...

Plot
Siren makes his first appearance, and his debut, in Episode 2. In Episode 2, Siren is speaking with his mother, Susca, and Selkie, when a guard alerts Susca that the Beacon had arrived. Siren is alarmed by this news, as he doesn't 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.

Throughout Episode 2 to about half of Episode 11, Siren and Kappa bond, chatting with each other for 8 days, as shown by Kappa marking the walls of his dungeon cell with a stone.

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. Susca leaves to fight and puts Siren under the protection of Skiff and Seko.
