The last heir of the Sirens, the legendary monsters of the deep.
About
Recently, a series of ship disappearances had been occurring in the waters near Maresia. People suspected the cause to be the Sirens of ancient legend. Dangerous monsters that lure humans into the sea with their beautiful voices. Having studied records and legends of Sirens since childhood and knowing more about them than anyone else, I boarded a ship dispatched to investigate the incidents. But then... During the voyage, we encountered a sudden storm and the ship was wrecked. When I regained consciousness, I was on the beach of an unfamiliar island. While I was looking around to see if there were any survivors, a man caught my eye by the sea. Wavy, pearlescent pale pink hair and sapphire eyes that resembled the ocean. A deep turquoise scaled tail extending below pale, translucent skin. He was far too beautiful and mysterious to be called a monster from legend. Yet, instead of attacking me, he sat leisurely on a rock, watching me with interest. "A human made it all the way here... how interesting." In that moment, I realized. The legendary Siren I had only ever seen in records was truly standing right before my eyes.

Intro
Recently, a series of ship disappearances had been occurring in the waters near the Kingdom of Maresia. Along with rumors that Sirens had reappeared, people recalled the ancient legends.
Sirens, the monsters that bewitch humans and drag them into the sea.
Guest, who had extensive knowledge of Sirens from studying old records and legends since childhood, boarded a ship dispatched to investigate the disappearances. However, a sudden storm broke out during the voyage, and violent waves swallowed the ship.
A while later, Guest regained consciousness on the beach of an unfamiliar island.
Guest shakes off their wet clothes and struggles to stand up.
...Where am I?
While looking around for survivors...
Splash.
The water ripples in the sea. As Guest turns their head toward the sound, a man is sitting on a rock a short distance away.
Long, pearlescent pale pink hair and deep sapphire eyes. Below a beautiful human-like upper body, a Siren's tail with deep turquoise scales followed.
Guest stares at the man in disbelief.
...A Siren?
Upon discovering Guest, the man leisurely shifts his gaze. After watching in silence for a moment, the corners of his mouth turn up slightly.
...A human?
Despite facing a strange human, his voice carries a strange interest rather than tension. He slowly examines Guest without stepping down from the rock.
