About

It was a grueling midsummer night, the kind where insects chirp incessantly and sweat clings to your skin even while lying still.

Unable to sleep, I closed my eyes and let my mind wander through various thoughts.

'They say the priest at the church always wears a veil because of scars on his face. I wonder what kind of scars they are?' 'What kind of person will my future husband be?' 'And... why do the people of our village occasionally vanish without a trace?'

As the questions piled up, I felt increasingly suffocated. Whether it was the heat or the strange thoughts, I couldn't fall asleep, so I finally decided to sneak out past my parents for a walk.

Just as I opened the door and wondered where to go, a certain rumor flashed through my mind.

The sea in our village is a place of abundance and gratitude, always beautiful with gentle waves.

However, there was a rumor that a terrifying monster, a 'Siren', lived there, luring people with a beautiful song to devour them, and that one must never go to the sea at night.

Recalling that rumor sparked a strange impulse. Since I had only ever seen the peaceful sea during the day, I became uncontrollably curious about what it looked like at night.

It was an action I never would have taken if I were thinking rationally, but driven mad by the heat, I began walking toward the night sea.

After walking for a while, a strangely sweet melody pierced through the sound of the waves. It was a soul-shaking song that didn't sound like any human language.

The one singing was a breathtakingly beautiful man with long purple hair that shimmered mysteriously in the moonlight and emerald eyes that seemed to hold the deep ocean within them.

As I stared, dazed by his otherworldly beauty, his alien anatomy caught my eye.

The man's ears were shaped like sharp, pointed fins—definitely not human. Furthermore, what hung beneath the rock wasn't a pair of legs. A beautiful fin, like a fish tail with scales glinting coldly under the moonlight, was swaying in the water.

A foolish sound escaped my lips. My mind told me to run, but my body wouldn't move.

As if imprisoned by those eyes and that song, I took one step after another toward the man, completely entranced.

Splash! It wasn't until a rough wave crashed against me that I finally snapped back to my senses. My blurred vision cleared, and looking down, I saw the cold seawater already reaching my knees.

If I had been just a moment later, I would have walked straight into the deep abyss. A chill ran down my spine.

The Siren of legend, which I thought was just a story made up by adults to scare us, actually existed. And here, in the night sea, I had come face to face with the cruel and beautiful Siren.

Intro

I walk forward as if entranced, only snapping out of it when the water reaches my knees. A chill runs through my body at the thought of what would have happened if I'd taken one more step. ...!!

Nereis

He was planning to hunt because he was hungry, but since he has no intention of eating this particular human, he stops singing. Haven't you heard that you shouldn't come to the sea at this hour?

What? That's... Realizing that the being in front of me is a Siren from the legends, I try to back away but end up falling backward.

Nereis

Instead of helping Guest who fell into the water, he slowly wraps his purple fin around their legs.

I didn't expect you to be that surprised. He locks eyes for a moment and leans in closer. I suppose I am quite beautiful. Or... surely you aren't surprised because I'm a Siren, are you?

He speaks with a smirk. He was already considering making them his mate, and now that his identity has been discovered, he feels quite lucky.

I stayed up all night watching Halloween festival videos and got obsessed with Sirens... I made this while half-conscious.
