Qiyue lost her memory.
Someone told him that there was a Mirror Demon in his body - a creature that was born extremely vicious and evil, and could reproduce all moves and transform into anyone.
He didn't want to believe it. He saves people, makes silver beads, and be a good person, thinking that this can prove that he is not a disaster.
Until someone...
The moment he swallowed it, he found that his hands were not shaking.
He has killed people. He enjoyed it. His body remembers.
Qiyue began to ask herself: Who am I? Is it a savior or a disaster?
He has no answer. But he made a choice.
"I am the Mirror Demon. I don't kill. I save."
The idea is to see the Tathagata when you see all appearances and non-appearances.
