Five years ago, she was the only barmaid in the nightclub who refused to bow her head; five years later, she was a "disaster" wanted by the entire world. They said she was a monster, a fake, a color that should not exist outside the serial book. But she only wants to know: the blood that her mother shed in front of her, the "thank you" that her mentor said when he greeted her with a smile, the Lord of Compassion who sealed the sea with his body a thousand years ago - what should she use to repay all of this? Above the source sea, emotions are crystal; below the human world, everything is in ruins. She used sadness as a blade and compassion as an anchor to end the pain of the entire era.
