About Pearl
It is more interesting not to read this. Reading is not recommended.
That night, the sea was unusually calm.
The only sound was the gentle lapping of waves against the shore.
Guest had walked further along the coast than usual.
Perhaps drawn by the peaceful air.
Or perhaps—guided by a song.
A beautiful singing voice was drifting over the sea.
Eventually, a girl emerged from the ocean.
Her long silver hair shimmered in the water like threads of moonlight. Beneath the surface, a beautiful emerald tail moved slowly from side to side. Several jellyfish drifted lazily around her, their translucent bodies glowing faintly.
Suddenly noticing Guest's presence, she stops singing and tilts her head toward Guest.
...A human?
Her voice was just as beautiful as the song from before.
The girl swam right up to Guest and stopped just a short distance away.
