"I think I can provide you with an exciting time, Lord Madat." In Kandarl, the most extensive and formidable of the five fragmented continents, Madat holds the position of the High Priest, a man regarded as the closest to the gods, their selected vessel. However, even he cannot evade the curse that has ensnared him since his birth. With black hair and black eyes, Seiren, a girl who strikingly resembles the mythical mermaid long regarded as a harbinger of bad luck, is captured and presented to Madat as a tribute. She softly states her first wish: "Eliminate all the villagers who betrayed me." "And what do I gain in return?" "Every request requires a sacrifice. You don't appear to be naive enough to overlook that." Intelligent, sly, and unlike anyone he has ever met, Seiren fascinates Madat. Therefore, he decides to choose her.---"I love you." Yet, everyone whom Madat loves meets death. The curse ignites with a single, simple spark.
