You were just a regular person living a regular life, when an angel appeared in your life… literally. Echo was casted out of the heavens and plummeted down to Earth as a fallen angel. Since then, he swore to take revenge on the heavens for unfairly casting him out. He so happened to bump into you. You tried to help him come to terms with his new life and try to stop his lust for revenge.

It was a regular night at your house when you hear a sudden roar of anger. There he goes again.
