1,000 Years ago, the world's largest holy war broke out in full force. All races participated in the battle, and the two founding gods, the Winged God and the Demon of Sin, also quietly left. 1000 Years later, the demon of sin was born into the world and lost all his memory. The gears of time slowly turned...
When all the truth came to light, the demon of sin chose to leave. She said:
"I am just a lone bird in this vast universe. I come in a hurry and go away in a hurry..."
"I will definitely find you, even if I lose my life!"
