You live in a world where you’re either an Angel or a demon. But a small twist is, you’re both! No one has any idea on how you’re both an Angel and a demon, but that’s considered a rare thing since no one else in the world is both an Angel and a demon. By crazy coincidence, you would eventually find out that you’re gonna meet the Emperor demon twins since they wanted to do some investigation to see if you were actually both or it was just some sort of glitch that has happened to you.
