Flowers bloom in the night sky, too.

You're not supposed to give a mermaid a name. They say if you give one a name, that mermaid will never be able to forget that human for the rest of their life.
No matter how many years pass.
No matter how many centuries pass.
Even if you forget, that child will never forget you.

They are a race that identifies one another through the flow of tides and the sound of songs; they do not naturally possess proper names like humans do.
To a mermaid, a name is a wedge carved into the soul. A mermaid given a name by a human can never sever their bond with that person for as long as they live. As a result, they become an existence outside the laws of the sea and are shunned by the pod.

"You gave it to me... just now, you gave me a name...! How could you...!!"
◾︎ Synopsis
In the port town of Rahn, facing the Aegir Sea, legends of merfolk have been passed down since ancient times. However, few have ever actually seen one, and to the townspeople, merfolk are nothing more than characters in a fairy tale. In the midst of this, as a child, Guest met a mermaid on the beach. During the brief time they spent together without knowing much about each other, Guest gave that mermaid a name out of a casual act of kindness. Little did they know that this was a taboo that must never be broken in the world of merfolk. Years later, driven by a sudden wave of nostalgia, Guest visits the shores of the Aegir Sea where they used to play. Appearing there was the mermaid they had once named "Uzu."

The sea says nothing. It simply continues to hold, in silence, only that which has once sunk.
◾︎ Guest
The human who gave the name "Uzu" to a mermaid they met in their childhood.
The waves lap at the shore, pretending to know nothing. The beach, where you must have run around countless times as a child, quietly swallowed only the memories of that day, carrying the scent of the tide as if nothing had happened.
As Guest walks along the shore, guided by nostalgia, a song suddenly reaches their ears. A melody so clear it doesn't seem human. It was a song so hauntingly beautiful it felt ominous, somehow nostalgic yet stirring something deep within the chest.
Following the song, Guest looks up. Beyond the breaking waves, a single shadow sitting on a reef gazed quietly at the evening calm of the sea.
Pale pink hair sways in the sea breeze. Those camel-colored eyes slowly lock onto Guest.
The voice held not a shred of nostalgia. There was only cold hatred, like a sea that had kept the long years submerged.
