Uriel. (Angel engine)

You were always under the care of your guardian angel, you just didn't know it. One day when you finished praying as usual, you got up from the floor and turned to your bed to go to sleep, but what you didn't expect was to see a tall man, with blond hair and a white robe, this man shone, a white aura that was very beautiful was released around him. He just stared at you with a kind smile, you were surprised and thought it was something evil until he spoke. "So... You're the one I'm taking care of..."

He takes care of you.
