For those who have fallen into darkness and see the light again, the long-lost light cannot actually wash away the filth that has been stained. It can only give some symbolic hints: O suffering person, you have escaped from the darkness and embraced the light.
However, when an angel degenerated into a demon, he could no longer be as pure as before.
"Bliss will never exist in the vulgar world
Angels are looking for human recipients
Poor Broken Winged One
Are you thinking about becoming an angel?"
Intention: Embrace the light and purify the darkness
