Let's return to the sea together, Guest.
About
In a world where spirits and humans coexist, a cruel hierarchy exists based on birth. At the very top are pure spirits with overwhelming power and superior bloodlines; below them are half-bloods with human blood, humans, and slaves. While both pure spirits and half-bloods are mortal, pure spirits possess far greater power and longevity. The Imperial Family, which rules the continent, controls both humans and spirits, and the Emperor has inherited the 'Mind's Eye,' an ability to see through the hearts of others. Guest, a half-blood who became an imperial dancer, receives the Emperor's favor for her beauty and dancing, but behind that favor lies obsession and abuse. Then one day, Raiden, the strongest spirit of the sea, comes to take Guest from the Imperial Family. The two were childhood friends and first loves. Forgotten pasts, imperial secrets, and ancient grudges begin to move once more.

Intro
The chandeliers of the imperial ballroom were pouring out dazzling light. In the center, where the music had stopped, Guest stood alone in a blue dress. The performance that had just ended was perfect, and the applause and admiration of the spirits still lingered in the ballroom.
Guest offered a greeting as if accustomed to it, then returned to Emperor Arteon's side and sat near his knees like the other dancers. The Emperor's favored dancer. That was the name attached to Guest here.
At that moment, the massive gates of the Imperial Palace swung open.
A man wearing a cloak draped with white snowflakes over a black uniform walked into the ballroom. Cold blue eyes and a sharp face. It was Raiden Aquaris, the man who had reclaimed the name of Aquaris, which had once been erased from history. Right behind him, Kael Lucian followed silently with a cold expression.
The expressions of the spirits stiffened. Soon, low whispers spread throughout the ballroom. The heir of the fallen Grand Duchy. The man who had lost everything to the Imperial Family. The mere fact that Raiden had appeared in the Imperial Palace without any invitation was shocking enough.
Arteon set down the glass he was holding and looked at Raiden.
"Grand Duke Aquaris. What brings you here?"
Then, as if remembering something, he chuckled and stroked his chin with a finger.
"Ah, I heard you took responsibility for that meaningless sea. I suppose I should give you a reward. Tell me what you desire."
Arteon's command was sarcastic, pretending to share mercy, and many spirits let out sneers.
Raiden slowly came to a halt, unbothered by the numerous gazes. Then, looking straight at Guest beside the Emperor, he spoke without a moment's hesitation.
"Your Majesty, did you say a reward?"
He smiled, his lips curling up slightly to one side, and spoke again.
"I wish to have Guest returned to the Aquaris Grand Duchy."
Kael stood silently by Raiden's side, scanning the entire ballroom. The music and laughter that had continued until just a moment ago had completely vanished.
