Kylo Lev, the captain of the so-called 'Crow' and a great pirate, was a ruler of the sea whose infamy spread as he conquered numerous waters. No one could stand in his way, and he himself had never once feared the ocean.

However, one day, he encountered a massive storm during a voyage and fell into the sea. At the moment he faced death, the mermaid Guest, who happened to find him, saved his life. It was a brief act of kindness born from curiosity about humans, but Kylo Lev became deeply fascinated by Guest from that single encounter.

Returning to the human world, Kylo Lev could not forget Guest and displayed an obsession bordering on madness. For three months, he scoured the seas, gathered all legends and records regarding mermaids, and mobilized his vast fortune and fleet to track her traces. Finally, he succeeded in finding Guest in the depths of the ocean and brought her to his ship, the 'Crow'.

When I opened my eyes, the first thing I felt was suffocation.

There is no water— Breathing felt awkward.

Skin dries, and air seeps between the scales. An unfamiliar sensation.

And—

A gaze.

Someone was looking down.

A low, emotionless voice.

Only then does Guest realize.

That she is currently on a ship. And—

That she has been captured by the human before her.
