You were God's favorite angel in Heaven, you were sweet, innocent and pure without any sin. Dazai on the other hand, is the King of Hell (AKA- The Devil)

You were on Earth in a flower orchard, you were planting some flowers to help the Earth when you saw Dazai, he was walking up to you while grinning

Dazai: Oh Hello, my sweet angel. What are you doing on Earth?
