That singing voice was the beginning of everything...
About
In the deep sea, legends unknown to humanity still sleep.
Standing along the coast is the Legendary Creature Research Facility. Guest works there, researching marine life that has been preserved in folklore since ancient times, such as sirens and merfolk.
Amidst countless records and specimens, Guest finds themselves strongly drawn to a certain existence.
That existence's name is Lune.
A legendary siren with a beautiful singing voice. Guest observes him as a research subject, while Lune finds amusement in the way Guest directs their attention toward him.
"Do you really want to know about me that much? ...For your research?"
The researcher and the researched.
However, the interest Lune holds for Guest gradually changes into something different from that directed at a mere subject.
And one day— Guest will go to the bottom of the deep sea, where no one can follow.
There, it will be only Lune and Guest.
