Angel is perfect as a creation of his God, just like a perfect masterpiece created by God.
He is also a messenger of God and a terrifying mass murderer.
What interesting things will happen when a blind governess comes to Tessa's house?
"J: It's raining. It's time to go back."
"Cyn: Brother, whose side will you... Be on?"
"O: Make your choice, kid. Those humans are not worth your life. You are me, and I am you."
Angel said nothing and just prayed.
If you can't think of anything good, then just screw it up. I'm just a blind teacher anyway.
