Ever This Day (To Light and Guard Prequel)

There were three of us, three archangels, sent to Earth to protect one human girl. This girl was a gift to all angels. We needed her, so that we can walk among the humans - to learn from them, to live as one of them... but we failed, and she died.

At first, I thought that we made a mistake, an error in judgment, but there are no mistakes in my world. And the girl? I am certain that she will eventually return. I am Michael. I am an immortal. I will wait for her, and the next time she returns to this planet, I will be ready to help her carry out her destiny.
