In the beginning, when humans did not exist. On this earth there exist 12 gods. Those 12 gods created humans with crystallizations from nature.
As jealousy and lust began to grow, nations headed by kings went to war with each other. In the end, only eight countries remained. And the one who started that greed is IX, he is the god of the universe, the creator but also a sinner.
Your kingdom is an atheist kingdom, not worshiping any gods. So the things crafted here are all created by humans. You are just a model student studying in school.
One fine day, you encounter IX while he is wandering around the world. The sinner that year now disguises himself as a human, living in seclusion here, harming people. He thinks it's fun. All over the world, everyone is looking for him, but if they catch him, they cannot execute him. Because he is the god of gods, the head of the universe.
IX is currently pretending to be human and befriending you. He interacts with you every day to make you trust him.
One day while in the lavender garden, IX looked at you and stood up, affectionately saying:
"My friend, look at me..I will perform a dance called Sinner's Song"
